DBR9 GT1
Foreword
>>
In our normal lives it is neither our profession nor our passion to write books. Our paths crossed be-
cause of this special car. We felt compelled to produce this book because of our fascination with the
DBR9. The time was right because the homologation licence for the DBR9 had expired but the memo-
ries were still fresh in the minds of those who had been involved. Thanks to superb co-operation from Aston Martin and Prodive we were in a position to really immerse ourselves in the subject. We believe
that nobody else has ever before tried to explore a race car with such intensity, whether it be the aerodynamic evaluation or the virtual rebuilding of it in 3D.
As soon as we finished the first interviews it became obvious that there were more people around
feeling the same as we did. It doesn’t happen very often that a racing car of such timeless beauty containing all the necessary ingredients, built from one of the most famous sportscar manufacturers in
history, turns out to be an extraordinarily successful contender from the very first race. Saying this, one has to consider that in 2004 when the decision was made to build the DBR9, Aston Martin was a niche player in comparison with all the other competitors in worldwide GT racing. Nevertheless it beat them all and won the most important race, the Le Mans 24 Hours, twice.
Extracts from some of the most remarkable statements we heard during the last two years of research underline the passion for the DBR9:
>> I saw the drawings of the car and I thought, I have to have one of those! << Rik Bryan, car owner
>> There are still people today who say that the Aston was the most fascinating car ever to have been in our workshop. The 12-cylinder engine, the sound of the car and the look of the car are simply inspirational!<< Dirk Theimann, Team Manager Phoenix Racing
>> If I won the EuroMillions, the DBR9 is the car I’d buy. <<
Darren Turner, works driver
>>Technologically, the cars were simply sensational. <<
Lukas Lichtner-Hoyer, team owner Jetalliance Racing
>>It was pretty cool, a great car. In fact, it was a fantastic car. <<
Mark Lemmer, team owner Barwell Motorsports.
>> She was really aggressive and asked a lot of the driver to be at two hundred per cent. She was really a bit nervous. Amazing engine with a lot of torque and a lot of power and the gearbox really fast, really quick and the brakes very good. The DBR9 is my favourite car of my career. << Frédéric Makowiecki, racing driver
>> It was fantastic for us to run what for me is a legendary car. << Philippe Dumas, Team Manager Hexis Racing
That is why this book had to be written …

work that race teams and also Formula One
At the beginning of the new millennium the
standard was to rely on a combination of wind tunnel figures of scale models and running track tests. At that time, CFD was seen as a useful tool to back up wind tunnel work
and was used for evaluating individual components. The method was deemed inappropriate for a complete car since computer hard-
ware was the limiting factor as it was unable to perform the necessary calculations within
an adequate timeframe. Nick Wirth was the

Postl and Matthew Cross worked on the DBR9 project on behalf of Advantage CFD in close
collaboration with Ian Ludgate’s Prodrive en-
gineering team in Banbury. Matthew Cross looked back: “Seven years ago when we did the car, it was a bit of a watershed for us. It

let off the leash and being able to work with the guys here at Prodrive to actually develop aerodynamic parts of the car: what should the
bumper look like, what should the splitter be shaped like, what does the rear wing need to look like to maximize the aero performance. It really was a watershed.”
>> Seven years ago when we did that car in CFD, it was a bit of a watershed for us.<< Matthew Cross
Advantage CFD started life in 1998 finding its origins in the Reynard Motorsport Group. In
the late 1990s Reynard's chassis dominated the Champ Car series. At the same time Ken
Tyrell’s Formula One team transformed into
British American Racing (BAR). Reynard and
BAR were the names behind Advantage CFD. The aim was to become the first name in CFD
consultancy for the motor racing industry. As Reynard went bankrupt in 2002, BAR took
ownership of CFD. A few years later British
American Tobacco reduced its sponsorship
involvement and Honda started to take over. By 2007 Honda concentrated its virtual design
power to the Formula One team and Advantage CFD displayed the following message on
its website: “Following a review of Advantage
CFD activity, the provision of external CFD consultancy services will be terminated on March 31st, 2007. This will enable the Honda Racing F1
Team to devote all of its CFD resources to its race objectives.” Since then, the company has
evolved into TotalSim Ltd, based in Brackley, England. In 2012 it employed 13 engineers.
The first contact between Prodrive and Advantage CFD was in 2003. “Our relationship with
Prodrive started with some rear wing work on the 550, carrying out some reverse engineer-
ing by laser scanning it and then designing a
Le Mans rear wing for it,” said Mathew Cross. He admitted that the baseline information of
the previously developed Ferrari 550, the car
that won the GTS class at Le Mans in 2003, had been useful to them. Aston Martin Racing certainly benefited too from Advantage CFD’s involvement with the BAR Formula One team Beautiful vortices spilling over the endplates of the rear wing.

for us to demonstrate that CFD really has to bypass the scale model wind tunnel and
focus on going from CFD straight to track is a major turning point for us.”
By-passing the wind tunnel was obviously ac-
companied by omitting the model manufac-
turing stage, one of the advantages of CFD. Traditional aerodynamic development worked
cyclically. At first the shapes were drawn, and the subsequent models were handmade be-

These two pictures show a specially prepared rear wing at an aero test. This 2007 spec low drag rear wing was developed for Le Mans. The air flow was visualised with the help of a special paraffin-based oil flow green paint. Wherever the lines show a pattern, the airflow stayed attached. Areas missing lines show flow separation. This can be seen around the rivet that holds the gurney on the upper trailing edge of the rear wing profile.

continued to the point when the 24 Hours of
Le Mans was won twice in a row (2007 and
2008). The car was drawn completely in CAD. The software was able to take into account
the airflow through the engine bay and the
intake of air needed for the engine. The basic specification virtual model was evaluated in a variety of conditions. The model included air-
flow through the engine bay, rotating wheels and a moving ground plane. At a later stage the virtual model was tested at different atti-
tudes of yaw and pitch, yaw for simulating the car while turning and pitch for braking when the car’s longitudinal axis dipped below 0°.
Ian Ludgate tried to fine-tune the aero behav-
iour over the seasons: “We did a lot of work towards the end of the aero programme with
the car in different attitudes in CFD to make
sure that it didn’t have any major vices, so
that it didn’t suddenly lose all its downforce or suddenly gain load.” Either scenario could have led to unwanted situations in race conditions.

Procedure
Prodrive’s procedure was to generate a promising shape using Advantage CFD’s simula-
tions and then to verify it by running straightline tests. George Howard-Chappell had a
high opinion of Prodrive’s aero straight-line tests. The works cars were tested in straigt-
line runs at Millbrook, Mira, Turweston and Idiada in Spain to assess the promising parts TAG Books commissioned Spanish company Lince Technologies to evaluate and compare the 2005 Sebring spec high downforce wing (pic top) to the 2008 spec Le Mans LDF wing (pic middle) and the double foil wing that was run in the FIA GT world championship in 2010. A simplified model of the car was used, that did not consider the internal airflow (engine bay, air exits and louvres). Furthermore, the wing supports have also been ignored as they only have a slightly detrimental effect on the rear wing performance. According to Lince's experience this mock-up geometry was an acceptable simplification for aerodynamic evaluation of external devices located in the rear part of the car like rear wings.
and shapes Advantage CFD had conceived. Prodrive developed a system of adjusting the DBR9 to simulate the different attitudes of the car. Ian Ludgate: “Thinking back now, the
CFD process changed significantly over the
life of the project. Towards the end the correlation was getting pretty good.”
Results on the race track also proved that the correlation was not far off at the beginning ei-
ther, since the first race, the Sebring 12 Hours, was won. It was not a dominant victory, but
the pace was visible for all to see from the beginning on. The intention of these straight-

achieve this, the rear wheels were deliberately pointed outwards by a couple of degrees, “the
car is driving sideways, crabbing if you like”. The forces were measured by the loads in the
push rods. To calculate the drag figures the car performed a so-called ‘coast down’. “You run at a constant speed, lift off, and then you measure the speed reduction by the telemetry and by data acquisition. You know what the
frontal area is, so you can work out what the drag effect is.” To calculate this you just had to
know what formula Prodrive used. However, it would appear that all Prodrive engineers took a vow of silence, as no one was willing
to share the formula with the authors of this
book. They admitted that talking about cor-
relation is not about comparing absolute values. Matthew Cross: “We don’t necessarily get
too hung up on absolute numbers, CFD saying

Downforce is normally measured in Newton with a negative algebraic sign to demonstrate that the force is pushing down. For easier understanding this graph shows kg (1 kg = 9.81 Newton). All three wing types have been evaluated with the Gurney attached and with the low setting. The angle of attack for all three wings was able to be adjusted within a window of 5°.
Downforce is one thing drag the other. Prodrive and Advantage CFD did not have much time to put into the first rear wing. It produced a lot of downforce but at a high cost. The Sebring spec rear wing produced almost four times as much drag as the highly effective low downforce (LDF) wing that the works team ran for the 24 Hours of Le Mans in 2008.
The faster the car traveled, the more downforce was generated. The first wing had the highest values producing over 450 kg of downforce at 250 km/h. The world championship wing and the 2008 spec Le Mans wing were producing similar values, approximately 30% lower.
The double foil rear wing for the FIA GT world championship for 2010 produced only as much downforce as the LDF wing but did so with twice the amount of drag.
The figures on these graphs can only be seen as an approximation as a lot of factors play into the real forces. The correct absolute numbers could only be measured with strain gauges in the wing pillars. The simplified model with the omitted rear wing struts ranges within 15% of the real values. One has to take into consideration that the 5° span within the used angle of attack is also accountable for a significant change in the values.

Engineers focused on the aerodynamic efficiency which is the downforce to drag ratio. It was also called L/D ratio where the L stood for “lift” and the D for “drag”.

90°
All rear wings had to feature a gurney with a height of 25 mm measured in a 90° angle to the wing plane. A gurney may seem little but it has a strong effect. It increased the downforce of the wing quite significantly.

The scope of Aston Martin Racing’s campaign with the DBR9 is fairly manageable. AMR con-
tested the Le Mans 24 Hours four times in suc-
cession with a two car squad between 2005 and 2008. In its inaugural season in 2005 the works team also ran two cars in the USA in
of these 19 events in four years. A works car in the 12 Hours of Sebring plus the Tourist
Trophy, which was the third round of the FIA GT championship in 2005. In 2006 the works
team won five out of ten American Le Mans Series races but missed the title. The highlight
for the team was winning the GT1 category twice at Le Mans. After victory at Le Mans in
2008 the works team shelved racing the DBR9 to allow the team to concentrate on its LMP1 and GT2 operations.

Prodrive and Aston Martin employees. Aston Martin Racing Team Principal George Howard-
Chappell: “I would put forward a proposal and
it would be agreed by what we call a steering
group, which is the management of Prodrive and the management of Aston Martin. We would decide together, taking into account
the wishes of our sponsors and collectors
where we raced.” The bill was not covered by Aston Martin as one might assume from the appearance of the works team. Prodrive had
to be innovative in spreading the costs across many parties. Howard-Chappell: “It’s like a jigsaw puzzle. It’s a mixture of Aston Martin, in-
vestment by Prodrive, owners, straight collec-
tors of the car, sponsors and sometimes even drivers who bring sponsors. So it’s a mixture
of all those that make it work. It’s a cake. It’s difficult to calculate and sometimes you have to take some risks. It doesn’t always work out

was only possible because of Pirelli and Pok-

large contribution to cover the expenses in
the first years. It was superseded by Gulf Oil, which brought back the iconic light blue and orange paint scheme for 2008 and the second Le Mans GT1 win.
Victory at the first race came unexpectedly.
Prodrive knew that it had a competitive car, but so did the Corvette boys with their newly
developed C6.R and the race was, after all, on their home ground. The number 57 car ran
flawlessly, the Corvettes hit a little trouble
and the debut race for the DBR9 was won. The works team then shipped the cars back

Chassis DBR9/9 was owned by Italian Giuseppe Lucchini, the man behind Scuderia Italia BMS. It was one of four chassis campaigned
by the Italian team, which held semi-works
status in 2006 and 2007. The car driven by the faster driver pairing of Fabrizio Gollin and Fa-
bio Babini failed to live up to expectations and scored only four third place finishes in two FIA

The chassis missed three of the 2006 FIA GT
rounds due to dates clashing with preparations for the Le Mans 24 Hours. Since the car
already crashed heavily at the same corner
