DR FORMULA TEAM STARTS ON TOP

One of the toughest open wheeler championship, if not the toughest: with 41 drivers on grid, the F.4 Italia Championship collects the most talented drivers, mainly from karting. DR Formula driver Raul Guzman scored three podiums and is currently second in championship.

Great start for DR Formula at Misano for F.4 Italia Championship 2016: thanks to 58 points earned througout the last weekend, Mexican Raul Guzman is second in the overall classification just 8 VROOM INTERNATIONAL MAGAZINE

behind Mick Schumacher.

Guzman finished second in the first race of the weekend starting from the 7th position, and closing the race with just 1.3 seconds behind the winner. The Mexican stressed too much his tyres, being unable to overtake the leader who drived a consistent race. The battle for the first victory of the season took place during race 3, when Guzman replied a great comeback from 7th place and won ahead of Siebert and Van Uitert.

Another podium came in race 4 when the Mexican driver passed into third under the chequered flag.

Petrov Artem was 21st and 14th respectively in race 1 and race 2, while he did not finish race 4 because of a contact after only 10 laps.

Now the team is getting ready for the second round that will take place at Adria on May 8th.

After nearly a decade, the layout of the track in Sarno, the Circuito Internazionale Napoli, changes. No great changes to path that has evolved most of the current and those from recent past motorsport and Karting champions.

Most of Sarno’s iconic straights and corners have remained in the new layout: vehicles in the race course have maximum stress for both chassis and engine, and setup is never definitive or standardized. A challenge in the challenge to increase the value of a race in Sarno. The new 2016 track now measures 1,590 meters, 109 meters less than the previous one. A significant change is in the last part where once there was the famous and terrible “triple s” that disappears in the new design. Drivers will now turn left twice, then right, engaging and drawing something like a hook then into the usual last turn before the starting grid straight. Work is in progress also for park fermee structures.

On Circuito, crew are carrying out works on the asphalt at certain points as well as some curbs along the track. New Circuito figures: lenght 1,590 mt, 9 straights, 13 corners with different radius and 1 light chicane between the two segments of the main straight. “Circuito Internazionale Napoli” is getting ready for the Rotax Max Challenge Grand Finals 2016, next October.

IN THE NAME OF HIS FATHER Mick Schumacher is catching the media’s attention, and not only for his name: three wins in the first two meetings of the 2016 season. What a great start!

When your last name is Schumacher and you are a racing driver, your life will not be easy on a racetrack. Mick Schumacher knows very well how much pressure media can put on him very well, but he is coping well.

Mick started his career in karting in 2008, and won his first title in 2010: the Kerpener Kartchallenge Bambini.

The following year he passed to the ADAC Kart Master and in some international events until 2014, his last year in karting: he was second in both the European and the World CIK FIA KF Junior championships, and achieved good results also in KF Junior WSK Champions Cup and Super Master Series. 2015 has been his first year in the ADAC F.4 Championship, and he took a win and two podium places. He was also protagonist of a bad accident at Spielberg, where he broke his hand.

The 2016 season has started greatly: Mick is racing with Prema Powerteam in both ADAC F.4 Championship and F.4 Italian Championship. In the first round of the Italian series at Misano, he scored a double win in race one and race two, being the leader of the championship. Just

DANILO ROSSI ± DR FORMULA (F.4 ITALIAN CHAMPIONSHIP) ª This is the third year that DR Formula is competing in the F.4 Italian championship, and with 41 drivers on the grid we are pleased to be part of it. The main reason of the success is the direct effort of the FIA to create a series which helps karters to get into car racing. They wanted to create a defined path from karting to F.1: F.4, F.3, F.2 and then F.1. Young drivers must earn points for their Superlicence since their debut in F.4. Their approval is a guarantee for everybody. Moreover the car is absolutely fantastic: the Tatuus-Abarth F.4 is really reliable and cheap, and drivers are able to drive it fast very quickly. The engine is the deriving from the Abarth 500, slightly modified. It can produce 160 HP, which is a good power for young guys.

The paddle shifter makes everything easier.

Overall is a great championship for a relatively low cost.º

TRACK TEST TYRE TEMPERATURE WITH CRG-MAXTER

T

he analysis of the “excessively obvious”, almost neglected features of karts, goes on thanks to the instruments made available by Officine in Progress. As the temperature and pressure generated inside the braking system of a kart while making use of trailing throttle oversteer have already been dealt with, today’s topic will be a relatively established one: tyres heating up while being used. The fact of the matter is: how, and how much?

Such question required us to attend a CRG practice session in Lonato supervised by Dino Chiesa to be answered, as we mounted specific infrared sensors on the CRG-Maxter KZ2 kart of Japanese driver Fuma Horio, thereby recording what happened as test sessions were carried out and modifications were made. Here is how the test was carried out, and what the results were.

INFRARED MEASUREMENT

The three sensors used in this kind of measurement were of the infrared type, mounted in proximity of the rear and left front wheels (the latter being subject to more wear compared to the front right one, due to the shape of the Lonato track). Since sensors do not perceive temperature as heat, but as an emission, the datum is not affected by tyre installation distance. However, such distance influences the reading “cone”, and therefore the measurement area. The sensors were thus positioned so as to “point to” the most important part of the tyre tread, namely the internal one, with a 5-6 cm width.

As far as the rest is concerned, the usual sensors were used, including the GPS one, the one used to measure acceleration on the three axes, but also the one for braking system pressure, so as to collect data on the link between braking and tyre temperature. Worn tyres were used from the beginning, so as to prevent wear from affecting the measurements (and performance), whilst new tyres progressively wears (and get worse) after entering the track a few times.

22 VROOM INTERNATIONAL MAGAZINE

Team Manager Dino Chiesa and Andrea Saccucci analyse data

CHANGES DURING VARIOUS RUN

So as to fully assess the different results, here is a list of the set-up configurations of Horio’s kart, namely a CRG Road Rebel equipped with the latest version of the manual transmission Maxter 125 engine (the MX-S 2), together with the modifications made during the different laps.

47”027 - 132,4 km/h - 50°C average temperature The first entry was made with the standard setup as a reference point. The driver did well, though he said he would have preferred better cornering, due to the slippery track. The ambient temperature was around 25°C on average, and was therefore good.

SECOND RUN 47”382 - 133,0 km/h - 60°C average temperature The front caster was loaded with a further 1° for better cornering. The driver did better, though he complained about steering-wheel heaviness. Moreover, the pneus were loaded way more.

THIRD RUN 47”136 - 130,9 km/h - 65°C average temperature The last issue required tyre pressure to be lowered from 0.54 to 0.50 bars to be managed.

The kart “ran properly” a bit later, but little changed as far as exploitability and temperatures are concerned.

FOURTH RUN 47”330 - 129,6 km/h - 65°C average temperature More angled spindles (from 10,5° to 11,0°) were used at this point, together with standard setups, especially as far as the camber and caster are concerned. This way, the internal back wheel can be raised more, incidence being equal. The driver appreciated such modification, as he considered the kart as easier to drive and steer.

FIFTH RUN 47”720 - 130,2 km/h - 70°C average temperature The last set of laps saw the use of less used tyres for a final comparison, though things did not substantially change.

CHARTS SHOWING CORRELATION BETWEEN DRIVING AND TYRE TREAD TEMPERATURE, WHICH GENERALLY INCREASES AFTER USING TRAILING THROTTLE OVERSTEER 24 VROOM INTERNATIONAL MAGAZINE

HOW THEY HEAT UP

This first chart (1) enables one to see tyre tread temperature not only during the lap, but also at the beginning, during the first quick lap. Clearly, front wheel temperature (red line) increases in correspondence of braking points, and cools down during straights. The other two (green) lines, representing instantaneous speed and brake pressure, confirm it. The slight delay in temperature increase compared to the application of the brakes is due to the fact that the tyre needs some time to “generate heat” when stressed. Also witness how average temperature increases during the “warmup” lap.

4 STABILISING LAPS

The specific table (2) indicating back minimum, medium and maximum tyre temperature shows how long is required to adequately warm up tyres. Without considering the first lap, the minimum value of which is influenced by the equipment, the tyres clearly reach “decent” working temperature during the fifth lap. Indeed, 4 laps are required to “stabilise” wheels with a balanced setup (the standard one). After the eight lap, maximum and medium temperatures do not necessarily “agree”, which depends on the driver’s possible mistakes or slowing. A skid can significantly increase instantaneous temperature, while speeding down has the opposite result.

of the previous run: a maximum of 70°C in the first run, and more than 100°C in the second one.

Of course, several factors lead to this result: on one hand the increased load on the front axle, which led the rear axle to bounce while braking, thereby increasing the temperature of both axles.

On the other hand, the increased confidence shown by the driver with the more steering-oriented setup led him to tackle curves more aggressively, both when hard-braking and when cornering.

However, chronos went higher, and forcing tyres to work at temperatures higher than ideal could have played an important role in achieving this result.

SETUP EFFECT

The third chart (3), obtained after modifying the setup for the first time by Daniele Parravano and Andrea Saccucci of Officine In Progress increasing the caster angle so as to load the front axle, shows not only how the front tyre works during the lap, but also how it reaches temperatures way higher than those

VROOM INTERNATIONAL MAGAZINE 25

TRACK TEST TYRE TEMPERATURE WITH CRG-MAXTER

TEMPERATURE RANGE Speaking of ideal temperatures, those who deal with data collection can benefit from charts such as these, as they show the correlation between tyre tread temperature and absolute longitudinal acceleration (which means braking is also expressed with a positive value here), and therefore tyre performance. One instance refers to the front one (4), while the other refers to the back one (5). The areas where the red dots gather show where tyres work more, but it also worth noting that when the front and back tyres reach temperatures higher than respectively 83°C and 58°C, maximum performance is not achieved. Chart 6 is included for those who are more into telemetry, as it shows how this point of reference ª variesº during a first lap: the ª peakº reached between 60 and 63 degrees shows how the best performances are achieved within this temperature range.

Certain values achieved at lower temperatures (51-52°C) are the result of ª extreme manoeuvresº made by the driver to warm up the tyres.

LET' S NOT GET TOO HEATED Without lingering on details for too long, this test enabled us to understand that certain setup modifications are more effective than others as far as the working temperature of tyres is concerned. More in

26 VROOM INTERNATIONAL MAGAZINE

detail, modifications involving tyre or axle ª loadº (caster or height) have a significant effect, while others don' t.

Tyre pressure, for instance, does not significantly influence the final value, but it helps one to anticipate or delay when tyres work best. However, other than being lower than expected, tyre tread temperature proved important as far as tyre performance is concerned, being able to determine a better final result (namely lap time) more than certain modifications, especially when tyres reach temperatures higher than a specific limit. In short, tyre tread temperature should be taken in consideration more directly when trying to achieve the ideal setup of a kart. After all, certain motorsport experts are for real when they say that the car (or the kart) is a tyre accessory, and not the way round; even though it means development or set-up tests need a different approach.

required. Obviously the data system also registers situations where the kart is not flat out, but it’s obvious that maximum values are reached with a full open throttle. It’s interesting to see that this Maxter can supply up to 48.2 hp at 13,600 rpm, and almost at the same crotation speed it reaches 25.0 Nm maximum torque. Anyway, we can see that torque also reaches a good level between 11,500 and 12,600 rpm.

TEST

AND YET IT MOVES!

WE TESTED THE ELECTRIC KART FROM THE GSIDE PROJECT, A KART DEVELOPED

BY THE “UNIVERSITÀ DI CASSINO”. IT STILL NEEDS A BIT MORE ACCELERATION (BY CHOICE) BUT THE BASIS IS THE AND ON THE WHOLE IT HAS NOTHING TO ENVY “THERMAL” KARTS FOR. REPORT: M. VOLTINI - PICS: OIP

32 VROOM INTERNATIONAL MAGAZINE

In the previous reports dedicated to the “electrification” of karting, we have seen that there are already several applications with electric traction in motorsport and also in various indoor karting applications.

But what about kart racing? Well, we can assure you that: although we are undoubtedly in the early stages, the theoretic project level is over and done with, and there is already an electric kart lapping along the track. Even better, there are two. And we had a chance of trying one at the Valle del Liri track in Arce, near Frosinone, south of Rome.

The karts are those that have been developed within the GSide project (GSide meaning Green Side) from the “Università di Cassino and Lazio Meridionale”. However, let’s take a closer look at how this kart responds on the track.

STUDENTS’ DAY The day organised at the track in

Arce was for setting up two university teams that “compete” in the set-up of the two GSide karts on the track, and there is a third team that sees to the general development of the project (a sort of R&D department).

Remember that this is an idea starting from a university, therefore particularly aimed for student formation, giving them “on the field” experience that is very important for their future. This is why the result has been, to put it mildly, fantastic. About sixty students have taken part in this project, there are about fifty from Engineering and about ten from the Physical Science faculty.

This project started out in 2014 as electric kart “racing” and, if you look just at electric traction applied to generic four-wheeled vehicles we go back to 2013. In December 2015 they started to get students officially involved in the project.

With this foresight, the region Lazio funded the project led by university

professor Giuseppe Tomasso and supported by Aci Sport (the italian racing federation) in particular by Mario Bonifacio. Here a mention goes to the technical partners who have helped to define and develop these karts, BAR Engineering and Officine in Progress, they have always been there to give their help and support. All this of course, without diminishing the importance of the various “suppliers” involved each time for the various karting “accessories”, such as engines, batteries and so on.

BALANCED SET UP Now, what’s the GSide electric kart like? First of all, you start with a “normal” base, that is, a normal 125 chassis like the one used for KZ, and leave for example the braking system with disc also at the front (pedal controlled). Then the batteries, which are lithium polymer batteries, are placed at the side of the seat,

TRACK TEST

NOT JUST TECHNICAL INTEREST

The day spent at the track in Arce was very successful, Giuseppe Tomasso tell us all about it: «My greatest satisfaction is in seeing how an electric kart can draw so many youngsters closer to the

world of racing, even if at first it is for a mere technical interest.

Out of the more than 50 students, studying engineering, involved in this early phase of the project, more than 30 had never driven a kart and half of them hadn' t ever even been anywhere near the sport world involved with motor racing. They are stimulated, we are stimulated by the fact that we are planning to make ecological racing vehicles, but preserving the environment (a noble aim) isn' t the only target, the aim is also to prove that electric vehicles can now compete on an equal standing with an endothermic one. Judging by the expression on the faces of those who drove our karts last Sunday, I think that we are gradually getting there».

34 VROOM INTERNATIONAL MAGAZINE

between the seat and side pods: this location is quite protected and allows you to put them there without changing the weight distribution.

For the time being, there is a battery charger, ª slowº mono-phase 2.4 kW, but with a three-phase current you can have 7kW ª fastº one.

An electric engine was mounted in the usual position, therefore, without needing to change anything; a commercial model was used, a three phase asinchronous one capable of reaching 8000 rpm with a 21 kW power peak (that is, about 28.5 hp) besides 58 Nm maximum torque gained at about 3000 revs.

Drive as usual is chain drive, with a final ratio of about 1:4. Everything is run by a vector control inverter situated where the tank is normally positioned. We must also point out the potentiometer acts as an accelerator (controlled by the right pedal), communicates via CanBus, a Battery Management System

developed at home, and there are some protection and safety elements: GPS and crash sensors have been applied to the ª big general push-buttonº that allows you to disconnect energy delivery automatically in case of accidents.

The final result is a kart that not only limits weight to 115 kg (batteries included), but already at first sight shows a very ª cleanº general disposition, it is simple and linear without anything ª out of lineº , almost as if you were dealing with a 100 aircooled kart; and obviously, this is a compliment.

ELECTRIC SENSATIONS Obviously we were very curious on this occasion and couldn' t wait to try this kart personally. Once we sat in it, they told us that all we had to do was to switch on the red button and press ª forwardº with the switch below, the same one that controls reverse motion.

AN OPEN SOURCE KART To help the manufacturing of an electric kart and hence the entry to a future championship, and undoubtedly also because among the aims of anyone working in a university there’s also the will to divulge knowledge, the GSide project will also be available “open-source”. To be more precise, the part that is available to everyone

Yes, and at this point you realise that there is something missing, something whose presence we feared: the ª on-off effectº o n the gas pedal (so to speak), that is a brusque power coupling. Instead, thanks to the already advanced stage of the software used for this system, we find that everything is progressive.

Once on the track you are a bit ª bewilderedº b ecause there is no sound coming from the engine like we are used to hearing, but not for the lack of thrust: torque is good on corner exit, and even if it is expressed in a fluid manner it also allows you to control oversteering, so that in the mixed part of the track you don' t feel any particular ª strangenessº c ompared to a normal direct drive kart. Instead along the straight there is a bit of power lacking, but we must say that the vehicle had been a bit

ª cappedº o n purpose, so as not to go over the 7100 revs out of 8000 maximum. This is to allow all the students who have taken part in this test to lap before the batteries got flat (it should have about fifty minutes autonomy, in this modality, after being recharged for about 2 hours), maybe because the team' s approach has been rather prudent and they preferred to increase performance gradually.

The strange thing is that along the straight you can smell a sort of ª electricº scent, something that is technically due to the ionization of the air around the engine. If we get distracted by this, or by not hearing the ª roarº o f the engine, we will tend to relax; but then as we draw closer to the turn, at quite a speed, we ª wake upº a gain: an electric kart mustn' t be underestimated.

However, we can count on powerful controllable braking, either because of the three discs,

or because the recharge function on release (an electric engine also acts as a ª dynamoº w hen there is no thrust) also brings about a sort of ABS effect that makes the rear stable on braking. In this case, they didn' t use this function to the maximum, this is something that might make it possible to mount a smaller rear brake, or perhaps even do without. You can actually feel overall weight a bit, especially if you don' t take the curbs properly, but in the end the engine gets the better of the situation. Regarding this topic, we will have a separate column with the impression, very similar, that our collaborator Alessandro Roca had when he tried the GSide kart.

BRILLIANT FUTURE… COMING UP Well, the impression we got was that we had something that was worth having, even as a racing class to

A QUESTION OF SENSES support the usual racing categories, in the near future. In the meanwhile, we must say that, lapping alongside some 125 gear-class, you could see the difference along the straights; however, when the two GSides were running very close each other, the “race effect” was really positive.

Then we mustn’t forget that already in 2017 – if not earlier – we would be able to see these vehicles in real racing competitions. And, this we will get to after the forthcoming evolutionary developments. In this case GSide, already see the imminent arrival of a permanent magnet brushless engine with 50 hp (37.5 kW) and 70 Nm, electronic running with even more thrust looking to “racing” and having the battery packs (that will go from 72 to 88 Volts, always with 40 Ah) so it is easy to change them, or to be able to recharge them better. The time is right, and for once Italy is even ahead of other European countries.

OUR FRIEND ALESSANDRO ROCA TRIED THE ELECTRIC GSIDE KART TOO, AND THIS IS THE IMPRESSION HE GOT A human being relates to the world around him trying to make the most of his senses, and it’s here that things start being quite different: as there is hardly any sound or smell makes you underestimate this vehicle, it is as if we aren’t using two out of our five senses.

However, it doesn’t take long to see that things aren’t so, you only have to get closer to the early turns and press down the accelerator pedal. A lot of torque, even if it is limited for this occasion, and it’s immediately available.

The electric engine has a strong thrust, it is easily controlled and allows you to get a smooth fluid drive, without the normal aggression, which is typical of a two-stroke engine. Furthermore, it helps during the braking phase: thanks to the engine brake and a double braking system, you manage to brake determinedly without blocking the kart, with the kart “stopping dead” without forecarriage pecking down. The weight of the battery packs is felt, but they are well-distributed on the chassis avoiding any disturbance whilst driving.

Seeing how heavy it is, the only thing that you have to do is avoid jumping on the curbs too much, the batteries are thankful.

Basically speaking the first word that came to mind when I got out of the kart was: “strange”, but meaning it in a positive way! To tell the truth I was rather skeptical (complete opposite compared to the editorial line of the magazine), with my nature as a 23-year old who was nostalgic for the old motorsport, I’ve had to change idea: ladies and gentlemen here we have progress. The “soft” characteristic concerning delivery and the smooth drive make it a perfect instrument for newcomers to the sport and for children. To conclude, it would be really good to see these karts used for competitions, but (this is where nostalgia steps in) personally I can’t see them taking over from the endothermic karts, but as complementary to the latter.

TRACK TEST

SMOOTHER ALSO IN THE GRAPHS This time too, like in the other tests, we try to find some interesting comparisons in the telemetry supplied by Officine in Progress, who moreover in this specific case collaborates actively with the Università di Cassino in measuring everything that happens on the electric kart on the track, to be able to see what actually happens.

Graph 1 shows us a lap covered by the GSide (green line) compared with the lap of a 125 gear class (blue line). A comparison with a direct drive kart would have undoubtedly been more correct ª sports wiseº . However seeing that the federation has practically managed to make them disappear¼ anyway, you can see how drive for the electric kart is much smoother, more fluid with less ª peaksº both in longitudinal and lateral accelerations (LatAcc and LonAcc) and in speed.

In particular, you can see how the latter ª capsº also due to the software, and for this reason less current is absorbed by the engine: in fact, on corner exit, this ª strainsº and makes tension drop (vBatt) the same that later stabilises when less energy is needed.

Graph 2 focalises the internal part of the track more in detail, the part that includes the last four turns before the straight box.

38 VROOM INTERNATIONAL MAGAZINE

Graph 3 instead evidences parameters that are more specific for the electric kart: you can see how even in one ª variableº lap ( speed is given by the green line) the engine absorbs current in proportion as to how the kart is used (purple line) while tension (blue line) rises suddenly when you reach the braking points. This is the effect of recuperating energy on braking, and you can see how this represents a significant percentage in that part of the track. Well, when you get to the real competitions , it' s hard to underestimate (or ignore) this aspect of electric traction.

DRIVER PERFORMANCE ANALYSIS

ISSUE NUMBER 4 – Data analysis is not to be limited only to monitoring the engine or equipment: drivers are just as important. Very useful information can be obtained by “recording” all their movements, which can help the team as well as the same driver to understand how to improve performance… here’s how. REPORT: A. SACCUCCI - TRANSLATER: M. BUGIOLACCHI When one analyses the performance of a driver, they should not fall into a trap which usually leads to making modifications, almost on the starting grid during a race weekend: a problem “experienced” by the driver may be due to his lack of driving technique, and vice versa. Analysing what happens on the vehicle and what the driver does through actual data is paramount. Such phase requires the driver’s presence, as well as telemetry support.

Drivers are usually able to remember how the vehicle behaves bend after bend, lap after lap. Telemetry support is able to confirm what the driver says with actual data. Of course, the driver is required to learn how to read charts (also through specific training) by using basic techniques and knowing how the vehicle works, so as to improve performance.

Consistency: the cyclic nature of identical actions lap after lap, such as using trailing throttle oversteer always in the same point.

The image shows that stepping on the throttle too early (red arrow) in an unstable way causes an excessively early gear shift (black arrow), which leads the red track to go slower than the blue track in the straight.

The picture shows a breaking operation: the red track has achieved a better performance by raising the system' s temperature very quickly (aggressive braking). However, both are not very linear during the release phase, as the driver is forced to brake several times, thereby increasing braking time. Of course, this suggests that the driver has experienced too many problems when performing such manouvres. Further channels are to be looked for in the same turn.

Dear Vroom readers, we have finally reached the third and last part of this column on knock, where we are going to try to draw to an end (at last). I advise you to go through the previous two articles, since the topic below is the same. The physical nature and effects of knock have been described quite well up to this point.

However, if one does not know how to study, measure and prevent it (as far as possible), this information serves no actual purpose. Motoring enthusiasts like us have a tendency to pragmatism, as we deem theoretical knowledge useless, if it does not have a practical application.

TO JOE

I would like to end by remembering my friend Joe, who passed away two years ago. Not only was he a friend to me, he was also a mentor, a sincere and brilliant person. I remember the time we spent on the phone, engaging in small-talk for three, maybe three and a half hours, without mentioning motors.

His expertise, together with his culture and technique, always amazed me. No wonder he scolded me when I said “Joe, I don’t understand this stuff”. He got really angry! He had a vision, and most of the time he was right.

I still remember when, a few years ago, we spoke about why he had made “trefoil” plates, while sitting on the dismantled seats of an M5, or when we spoke about how to determine the perfect balance for a drive shaft, while eating on the balcony of his seaside house. He would play some Dream Theatre riff on his left-handed guitar, just like Jimi Hendrix’s… though he had never installed the strings the right way! He told me “Simo, I realised something was wrong, playing that way did not feel right… but who cares, that’s how I do it”. I literally burst out laughing.

He was unique.

Goodbye Joe, a lot of people miss you, I assure you of that.

CIK-FIA EUROPEAN KZ & KZ2 CHAMPIONSHIPS OUEST KARTING, ESSAY (FRANCE) 24th APRIL 2016 – 1st ROUND

Ardigò, chapeau!

SINCE THE LAST DECADE, THE PREMIER CLASS OF KARTING HAS THE RESPONSABILITY OF BEING THE MOST APPEALING SIDE OF THE SPORT AND THEREFORE THE MOST CREDIBLE AND SPECTACULAR OF THE KARTING CLASSES, THANKS TO THE PARTICIPATION OF THOSE DRIVERS WHO HAVE MADE HISTORY WITH THEIR CHALLENGES SUPPORTED BY STRONG PERFORMING RELIABLE ENGINES. THE FIRST ROUND OF THE CIK FIA WHICH TAKES PLACE IN ESSAY, FRANCE, CONFIRMS MARCO ARDIGÒ AS THE BEST. REPORT: W. GUCCI / PHOTO KSP

For those who live motor racing, crossing the finish line first is the result of many things, on which all competitors focus trying to win. These things affect their reputation because winning is the goal that justifies the commitment for an entire season. Winning the 125 shifter class means having the right mix of preparation, intuition and self awareness. Winning is the recognition of – work, which may last a lifetime, or perhaps just one day. Winning makes you a protagonist, a reference point for the whole karting circus. Marco Ardigò always shows his talent: his success in racing has never come by chance. His victories ripen during the race, facing each situation with the right tactic and his Vortex engine powered Tony Kart makes things easier for him. When racing at this level - strategy is very important. In Essay, on a particularly disastrous track condition, Ardigò is the master, the question is: who is going to be the driver skilled enough to beat him? Everybody wants to do better than Ardigò’s Tony Kart-Vortex; it is an obsession for all his fellow competitors because winning without beating Marco Ardigò is not considered creditable. To become number one in the world is fundamental, you have to win the duel against the Tony Kart ensign. Only - this way will such a victory prove to be worthy. Who will be the bold driver who will have the right equipment and skill to challenge the Brescian driver?

GAME OF STRENGTH

The first round of the European championship of the KZ and KZ2 final is raced with typical winter conditions (7 ° C), on a hostile track for tire life where it is hard to overtake.

Marco Ardigò, once again, risults impeccable and if he continues with this pace, it will be very hard for his opponents. Camponeschi and Iglesias step on the final podium with honour. Also Hanley is protagonist of a good race, but snubbing heats is not a champion behaviour.

Does the saying “well begun is half done” fit the situation? Looking at what happen during KZ qualifications it does not fit: Marco Ardigò is in tenth place, but only Pescador, Habulin and De Conto use slicks tyres resulting faster. Other drivers use rain tyres, being forced to settle for reserve positions. As said the track was a real puzzle, because also rain tyres on wet track wear out quickly. Qualifications result unreliable, whilst heats start anticipating better the real potential of participants.

Pescador remain the fastest, earning 52 VROOM INTERNATIONAL MAGAZINE

Above, Jeremy Iglesias (4) overtakes Ardigò on lap 6, he is unable to pull away from Tony Kart’s standard bearer. Below left, Flavio Camponeschi gets away from his rival De Conto and heads for flag

the pole position for the prefinal.

Also Paolo De Conto confirm what showed in qualifying. Good performance also for Iglesias, who join Ardigò on the second row. The third row is composed by Abbasse and Dreezen.

PREFINAL Flying start by Paolo De Conto, followed by Iglesias, Ardigò, Abbasse and Pescador. Ardigò sets the fastest lap, stopping the chrono on 48.600 seconds and overtaking De Conto on the following lap.

Ardigò gets away on the fourth lap, and behind his shoulders Dreezen is the fastest setting a lap of 48.479 seconds, overtaking Abbasse and chasing Iglesias. The Belgian wants to gain more positions, and he overtakes also Iglesias and De Conto.

On the seventh lap positions seem to be defined, and the race goes on smoothly except for the contact between Abbasse and Pescador, which forces the Frenchmen to the

16th position. Ardigò leads the race followed by Dreezen, who decides to settle for the second place after some furious laps. Also Iglesias prefers staying behind De Conto in fourth position. Fifth place for a brilliant Flavio Camponeschi who starts from the 14th position. Even Hanley, sixth on the finish line (which did not race the heats in order to exploit new sets of tires in the final stage), reaches his goal with 18 overtakings.

FINAL After qualifying session, heats and the prefinal race the final outcome of this first event begins to take shape.

Ardigò is the driver to beat. But who will be his antagonist?

After few laps Iglesias seems to be the most inclined to ruin the Tony Kart driver’s party. The Frenchmen easily puts his Sodi Kart-TM ahead of Ardigò during lap six, but the race is long… On seventh lap Camponeschi overtakes De Conto, starting his own race. Dreezen, who VROOM INTERNATIONAL MAGAZINE 53

CIK-FIA CIK-FIA EUROPEAN EUROPEAN KZ &KZ KZ2 & KZ2 CHAMPIONSHIPS CHAMPIONSHIPS

was one of the fastest in the prefinal race, looses the leading group. In the meantime, Marco Ardigò is following Iglesias as his shadow who is not able to exploit his leadership. In the second half of the race the pace starts slowing down, and during the fifteenth lap Ardigò overtakes the leader. Camponeschi is third and thanks to his pace slightly faster tries to catch Iglesias, who is opening a considerable gap from the leader.

Few laps to go, but the race is done.

Ardigò is getting ready to conquer the the first round of the European championship, leaving everybody astonished.

On the penultimate lap, Flavio Camponeschi gets the better of Jeremy Iglesias. Is the Roman driver the Ardigò’s antagonist? Looking at this first round he could be the right one. Anyway, Iglesias is happy for this podium in his home country.

Besancenez. Behind the leaders, a quartet of drivers composed by Piccini, Irlando, Davies and Tornqvist is fighting for the third place. In the second half of race, the leading duo increases his gap. Davies is slower than the other, but Tornqvist is not able to get the better of his opponent, underlining how difficult is to overtake. Pex wins the race ahead of Besancenez, who settles for second without trying to grab the leadership.

Piccini wins the duel against Irlando finishing third with more than five seconds of gap.

PREFINAL 2 Lorandi starts greatly, but he misses the breaking point on turn two and Corberi thanks. With dirty tyres Lorandi looses also the second place in favour of Gonzales. On third lap a motivated Federer overtakes Lorandi, getting the better of Gonzales on the following lap.

Fabian Federer (307) is once again the most competitive. His attempt to catch Corberi in the final and the remaining doubt whether he’d be able to overtake 3 laps from the chequered flag is worthy of note. Leonardo Lorandi (339) stops best practice time but loses pole after dueling with Pex and Besancenez race, but when finally is close to the leader the red flag is waving to allow the rescue of a commissioner hit by Matteo Viganò. The race is stopped and Corberi wins it, delaying the duel to the final race. Lorandi finishes third in front of Schmitz who started from the tenth place.

FINAL Pex and Corberi are leading the grid, followed by Besancenez, Federer, Piccini, Irlando and Lorandi.

After the green light Pex is still ahead of Corberi, but the Tony Kart driver exploits a rain shower during the third lap and grabs the top spot. Federer seems to be in perfect shape, and during the following lap is in second place. Corberi’s strategy pays off, and the gap earned in the beginning of the race is just unbridgeable and everybody looks behind their shoulders to mantain the position. In the end Pex, Besancenz and Lorandi are close to Federer and, with just two laps to go, Besancenez and Lorandi overtake Pex.

CIK-FIA CIK-FIA EUROPEAN EUROPEAN KZ &KZ KZ2 & KZ2 CHAMPIONSHIPS CHAMPIONSHIPS

TRACK On this occasion, the International Circuit Aunay doesn' t seem to be not so

appropriate for this event. The most important aspect is the difficulty in overtaking. It is a flowing track without important braking points and asphalt when wet is very rough and slippery. In brief theese conditions are the worst for racing at this level. The European KZ class needs perfect condition to allow these mini-racing cars to express their power.

Moreover, the tyres wear-out quickly: it seems that Vega sold more than 250 sets of tyres between Friday and Saturday to allow drivers to find the right set-up. Ironically, during the official qualifying session, slick equipped drivers are faster than drivers who mount rain tyres on a wet track. On the other hand, there is someone does undertsand the situation, Hanley, who preferred not to take part in the heats, he uses a new set of tyres for the prefinal; this allows him to overtake 18 times because grip is better (about 1º faster per lap). If you want to finish the race ª pedal-to-metalº is not very good. As the old saying goes, going slow is not always a bad thing, look at ª the hare and the tortoiseº . Out of those who know how to deal with tyres, during the early stages of the race Ardigò concentrates more on saving his tyres for later. During the final he decides to avoid duelling with Iglesias and prefers to let him go and wait for the right moment to get back into the lead and carry on from there

51 drivers from 39 nations attend the first round of the CIK-FIA Karting Academy Trophy, all motivated to win the opportunity to race the OK Junior World Championship that will be on scene on November 19th in Bahrain with a team of the OTK Group, official supplier of the trophy.

All driver were selected by their ASN respecting some characteristics: they have to be between 13 and 15 years old and they should never be ranked in the top 15 places of a CIK-FIA junior championships. One place is reserved for a lady selected by the FIA Women in Motorsport Commission.

From Saturday afternoon the Brit monopolises the higher step of the podium until the final race: an accident in the first manche involved nine drivers,

forcing the polesitter Thomas Mialane to slow down the pace. After the yellow flags, Bradshaw is able to exploit the re-start gaining the first position. The Brit replies also in the second manche, gaining the pole position for the prefinal race. The Frenchman Thomas Mialane has to settle for runner-up position, followed by Oliver Clarke (GBR) who will start third.

Despite changing climatic conditions, Callum Bradshaw wins both prefinal and final races leading the pack from flag to flag. In the prefinal Thomas Mialane steps on the second spot of the podium, followed by Mads Eielso Hansen (DNK).

The two drivers exchange positions in the final race, with the Brit always in front of the group.

Many engine exchanges were made at the initiation of our technical delegate without a variation in performance. The winner used different engines while remaining at the forefront of the category.

In the prefinal Tamsin Germain (DG Racing) and Richard Faulkner (Coles Racing) follow in second and third spot, but none of them could repeat the performance in the final. Here Slawomir Muranski (Wyrzykowski Motorsport) from Poland and Dennis Kroes complete the top three on the podium.

all four Saturday races in that order. They were also quick in the wet on Sunday though this time Carpenter missed out on a place on the podium to Brendon Hart in the second heat and Darren Walker in the Pre-Final.

DD2 Three drivers Daniel Bray, Mathew Kinsman and Josh Hart - battled hard on both days for class honours with Bray having the edge in the dry on Saturday but Josh Hart coming through to win the Final on a damp but drying track on Sunday.

Tyre choice proved critical in this race with Mason Armstrong and James Blair claiming weekend-best finishes (second and third respectively), Kinsman hanging on for fourth and Daniel Bray back in eighth place by the time the flag came out.

DD2 Masters Dry on Saturday or wet on Sunday, it made no difference, the pair claiming the only class clean sweeps (quickest in qualifying then eight race wins from eight starts) at the meeting.

Having - just - missed out a clean sweep at the opening double header round of this year’s Giltrap Group-backed New Zealand Challenge at Palmerston North in February, Urban at least had something

But to complete the challenge he still had to master two very different sets of driving conditions - warm and dry on Saturday, and wet and cool on Sunday - which was some achievement, and one matched by only one other driver over the weekend, recently crowned NZ Rotax Max Heavy class Sprint champion, 17-year-old Campbell Joyes. In the dry on Saturday Urban led home top female driver and former UK Rotax category rep Tiffany Chittenden in the heats and Pre-Final then won the Final from experienced sprint and superkart ace Karl Wilson from Wellington with Chittenden a DNF thanks to a brake issue. In the wet on Sunday Aucklander Aarron Cunningham, Wilson and Chittenden battled mightily all day behind Urban who again won both class heat races and the Pre-Final and Final, the latter from Wilson, Chittenden, Cunningham and Palmerston North driver Callum Orr. Rotax Junior Pukekohe teenager Matthew Payne dominated on Saturday but was pipped in the rain in qualifying on Sunday by in-form local driver Reece Hendl-Cox who went on to win both heats and the Pre-Final and finish third in the Final behind visiting Australian driver Cody Brewczynski and Wellington young gun Ryan Wood. A spin on the second corner in the Final put Payne back down the field but he retained his series points lead.

SUPER ONE SERIES RISSINGTON, CHILTERNS (UK) APRIL 24th 2016 – 2nd ROUND

SECONDS OUT Temperatures were unseasonably cold but the racing was hot at the high level Gloucestershire circuit amid the heart of the Chilterns.

The sun shone most of the day on the 133 competitors until a sudden sharp shower punctuated the second final of the official British Cadet Championship.

Jensen Butterfield enjoyed lights to flag victories in both MiniMax finals. Tom Canning had earlier topped timed qualifying from Jonny Edgar but Butterfield won both heats whilst Canning suffered an exclusion for a non-compliance. When Edgar took Lorcan Hanafin for second in the Dog Leg complex it gave Butterfield an unassailable lead he did not squander.

Edgar was bundled back to fifth but recovered for a three kart wide dash for second, taken by Dexter Patterson from Edgar and Hanafin. Butterfield again had a break in the second final when several karts went off including Edgar. But this time he was reeled in by Patterson and the recovering Canning to within half a second. Edgar recovered to fifth.

Joe Turney had the upper hand throughout timed qualifying and the two heats, lining up on pole for the first final with Jonathan Hoggard alongside.

As Turney took the lead William Pettitt slotted briefly into second until Hoggard took it back. Pettitt eventually claimed second with a light touch on Hoggard with Myles Apps in fourth.

Mark Kimber and Rory Hudson clashed on the last corner, Kimber surviving for fifth but Hudson out. Turney and Hoggard traded the lead in the early part of the second final until Pettitt fired his kart up the inside to lead. As the other battle continued to rage behind, Pettitt eased away for the win. Once Turney had flung off the attentions of Luke Ide and Tommy Foster he started to close in for the finish. Hoggard

endured a long grassy trip falling to seventh.

ABkC Rotax Max National Championship Josh White maintained his advantage from TQ through both heats to pole position with Josh Collings alongside for the first final. But White was immediately hobbled at the dog leg as James Johnson dived in, letting Jack McCarthy take up the lead. White started his comeback from tenth but the lead battle was a fierce rough and tumble of changing places, variously led

by Collings and Johnson. White also got back to the lead battle but a half spin saw him having to settle for fourth.

That fracas allowed Harrison Thomas to the front and he hung on for the win over Johnson and McCarthy. Briefly usurped by McCarthy, Thomas hung onto the lead for most of the second final until the last lap when White dived in and won from Collings and Johnson with Thomas falling to fourth. The latter two scrabbled over the grass at the

penultimate corner but made the flag.

The support race for Rotax Max 177 was won by Daniel Martin.

MSA British IAME Cadet Championship Georgi Dimitrov and points leader Harry Thompson were quickest in the time trials, with Thompson claiming the first heat, Bray Kenneally the other two. Kenneally and Thompson traded the lead in the first final with Rattican and Jonny Wilkinson battling behind.

After Thompson had eased Kenneally to one side on the penultimate lap they clashed on the final lap allowing

Rattican to take up the lead and win.

Whilst Wilkinson and Thompson slowed each other, Kenneally swooped round the outside for a provisional second until penalised 10s. Thompson also took a penalty but a successful appeal to the Stewards put him back to third.

Rattican was hung out to dry in the second final in favour of Thompson after many karts crashed at the first corner, including Kenneally. Thompson clung on to the lead ahead of Dimitrov and Tyler Read until a sudden rain shower had Taylor Barnard at one with the conditions catapulting himself from

Junior X30 International Qualifier Gordon Mutch had been fastest in the TQ but slipped a little in the heats, won by Jake Douglas and Ethan Pitt. A three way fight for the lead between Pitt, Douglas and Mutch became a five kart battle when Harrison Smith and Angus Fender joined in. But Smith was forced to retire whilst Mutch took advantage of the interference behind to ease away for the win. The very wet track suited Fender better as he leapfrogged Douglas and Mutch for the second final win. Behind Mutch and Pitt, Harry McQuillan moved up a few places for fourth, beating Douglas.

Sam Marsh won both heats from Matt Davies albeit Davies had been faster in the time trials. But Davies challenge in the first final was almost immediately thwarted when he was forced to stop. Marsh took full advantage, never headed as Scott Mackrell and Brett Ward fought over second. Charlie Bingham made a challenge on Matthew Hirst for fourth but ended bouncing along the grass for only tenth. Still wet for the second final with a racing line starting to dry from the half way point. Mackrell made a break over Marsh who had his rear filled by Ward until Collings came up to split them.

VROOMBOX USA – CHALLENGE OF THE AMERICAS SIMRACEWAY PERFORMANCE KARTING CENTER, SONOMA (CA) APRIL 3rd 2016 – 3rd ROUND

(344) CHRISTIAN BROOKS SECURED THE ROTAX GRAND FINALS TICKET IN SENIOR MAX WITH TWO VICTORIES IN SONOMA The 2016 Challenge of the Americas program came to a close over the April 1-3 weekend at the Simraceway Performance Karting Center.

Nearly 100 competitors traveled to the Sonoma, California facility, taking to the 3/4-mile course situated above the famous Infineon Raceway circuit, looking out at the Sonoma Valley. The championships in the seven categories were up for grabs in the final two rounds of the sixround title chase. For the Senior Max, Junior Max, and Masters Max title winners, it was a chance to claim a ticket to be part of the 2016 Rotax Max Challenge Grand Finals in Italy this October

Nash Motorsportz Senior Max - After missing the 2015 title for only four points, this year Christina Brooks made sure there was no question who the title winner was with two victories on the last weekend.

Brooks opened up the weekend with a victory on Saturday after running second through qualifying and the Prefinal. He drove away to a 4.2-second victory over championship contenders Kellen Ritter and Nathan Adds. The start to Round Six began with a setback, as Brooks was late reporting to the grid and not allowed to

take a single lap in qualifying. This put him 15th on the grid for the Prefinal. The 17-lap performance was championshipesque, posting fast laps of the race to finish second. Needing only to finish, Brooks had the title in hand but wanted more. He was shuffled back early but eventually reeled in leader Adds with three laps remaining. Brooks held on to record his fourth victory of the season, putting an exclamation point on his championship season. It was a photo finish for second with Adds scoring the runner-up position over Canadian Coltin McCaughan. Ritter and Jim McKinney completed the championship podium.

Rolison Performance Group Junior Max - Five victories in row for Nick Brueckner: he started the prefinal in fourth before winning both prefinal and final. Second place for Hannah Greenemeier ahead of Canadian Matthew Taskinen finished third for his fifth straight podium result.

Greenemeier came back Sunday as the driver to beat, again qualifying quickest before losing out to Brueckner in the Prefinal. The newly-crowned champion sat out the main event, putting Greenemeier

to the point. She led the first half of the race until Taskinen put up a challenge.

They swapped the lead lap after lap, allowing Riley Dickinson and Carter Herrera to close in. On the final lap, the top two went side-by-side entering the double lefts, both drifting wide and allowed Herrera to slip past. He held the lead to the checkered flag, earning his first series victory. Greenemeier settled for second, along with vice-champion with Dickinson into third to drop Taskinen to fourth, third in the championship chase.

Cambrian Go-Karts Masters Max - Carlos Calderon was the quickest driver all weekend, only able to win Sunday’s main event with Billy Cleavelin landing on top of the podium Saturday. Calderon was the top qualifier for Round Five, and led the majority of the Prefinal until a broken axle sidelined him, handing the race win to Roman Alekseenkov. Cleavelin started the main event third, and was into the lead early, driving away to a four-second victory. Calderon closed in the closing laps, only to lose his chain attempting to pass Cleavelin. Point leader Mike Jones secured the second position,

and the championship with his finish as Alekseenkov completed the race podium.

Calderon returned Sunday with fast lap in qualifying, but contact with Jones racing for the Prefinal lead cost him a chance at the win, which went to Cleavelin. The Round Five winner led the majority of the Final until a charging Calderon closed in and took over the lead. Calderon went on to score his first series victory by 2.3 seconds over Cleavelin with David Pergande in third for his second podium of the season.

Energy Kart USA Shifter Senior Âą This category saw a three driver battle with local star Brett Buckwalter joining championship rivals Jake French and Kolton Griffin.

French came away with a perfect score on Saturday, holding off both throughout the day to clinch the championship.

Buckwalter stole the second position from Griffin to end the day. Sunday was much of the same with the trio battling hard for

the lead position throughout the day. French edged them out in qualifying, while Griffin stepped up the pace to win in the Prefinal. The fighting continued in the main event with French able to cross the line first.

Officials however penalized the title winner for contact with Griffin, dropping him to third in the order to hand Griffin his second win of the series and move Buckwalter to second once again. French and Griffin were joined on the championship podium by Don Whittington.

ROTAX MASTERS - CARLOS CALDERON

The Dallas Karting Complex Shifter Masters was swept on the weekend by Patrick O' Neill with Kevin Woods placing second both days. The championship was awarded to Ryan Kinnear, who was absent on the weekend.

VROOM INTERNATIONAL MAGAZINE 89

VROOMBOX MICRO MAX - CARSON MORGAN

SHIFTER SENIOR - PATRICK O’NEILL Go Kart Hero Mini Max - 2014 Micro Max series champion Jak Crawford earned victory both days. Championship contender Austin Torgerson set the pace in qualifying, and the two battled for the win in the Prefinal. Each were awarded penalties for contact, thus handing the win over to Ashton Torgerson.

Crawford fought his way forward to land himself second, hounding race leader Dustin Salaverria. A last lap pass stuck for Crawford, earning him his first victory of the weekend.

Salaverria settled for second with Ashton Torgerson in third. Crawford swept the day on Sunday, making another late race maneuver to secure the win in the Final.

Salaverria crossed the line second but was handed a two-position penalty for contact, moving both Torgerson brothers Austin and Ashton onto the podium. Austin earned the championship by 32 points over Canadian Marco Kacic with Salaverria in the third position.

Ruthless Karting Micro Max - Championship leader Ashton Torgerson went winless in Sonoma, but secured the championship with a pair of top-five finishes. The race wins went to Carson Morgan and last year’s series champ Diego LaRoque. Josh Pierson, also making his series debut in 2016, set the benchmark in qualifying and the Prefinal, but the field caught him in the Final. Morgan and LaRoque hooked up at the start, pulling away early with Carson able to hold off Diego at the checkered flag by two hundredths of a second. Pierson crossed the line trailing in third. Sunday,

Torgerson put himself back at the front to help secure more points toward clinching the championship. Ashton was top qualifier and drove away to the win in the Prefinal. The top-five battled the entire 14-lap main event, but LaRoque got the better of his opponents being on top of the podium. Torgerson crossed the line in second with Morgan in third.

That gave Torgerson the championship by 47 points over Morgan with Tuesday Calderwood in the third position

Martono (KFJ) and Joyner (KF) grab the win at PFI, but despite the quality of the on-track action, the event was hardly a success. Too many problems afflict the sport, starting from ever-feeble grids. But dwindling numbers, now also at the highest level – both in directdrive and gearbox classes - is only the tip of the iceberg.
