SUPERFAST

The first and most difficult challenge Ferrari always faces when it decides to develop a new model is to push the boundaries of its own achievements yet again. This challenge is made all the tougher when the task at hand involves designing a new 12-cylinder engine, the power unit that hailed the start of the glorious Prancing Horse story 70 years ago in 1947.

ON THIS OCCASION, intensive research and development focused on exploiting Ferrari’s wealth of track-derived engineering know-how has produced a unique model designed to offer its drivers both benchmark performance across the board and the most riveting and rewarding driving experience possible. Whilst, of course, also guaranteeing the superb comfort on longer trips that is the signature of a genuine Grand Tourer berlinetta. Ferrari’s past is studded with just such cars, a long and illustrious list of exceptional models that have gone down in automotive history.

The obsessive pursuit of the most seamless melding possible of state-of-the-art running gear with a harmonious yet edgy design from the ever-inventive Ferrari Styling Centre, has produced a near-perfect aerodynamic package.

The 812 Superfast’s exceptionally futuristic, finelyhoned lines also, however, clothe Prancing Horse power at its rawest, as an entirely new 12-cylinder engine of unprecedented efficiency and might was designed for the car.

That engine’s output has been boosted by 60 cv compared to the F12berlinetta, so that it unleashes a massive 800 CV, making the 812 Superfast the most powerful and fastest road-going Ferrari ever built (with the exception, of course, of the mid-rear-engined, special limited-series 12-cylinders). The 812 Superfast thus ushers in a new era in Ferrari 12-cylinder history, in doing so, building on the invaluable legacies of the F12berlinetta and F12tdf.

To make full use of that huge power and to guarantee perfect weight distribution, the car exploits a highly evolved transaxle architecture that couples a frontmounted engine with a rear-mounted transmission.

The 812 Superfast is equipped with leading-edge vehicle dynamics control systems and components. It is striking for both its highly innovative design and aero package, as well as its unparalleled handling. It is also the first Ferrari to sport EPS (Electric Power Steering).

Simply put, the 812 Superfast is the new benchmark for mid-front-engined sports cars. And at its heart is the new 12-cylinder which has forged its character.

Like all cars with Prancing Horse DNA, this new berlinetta delivers exhilarating feedback both on road and track, but equally promises exceptionally fluid handling and ride comfort that drivers will appreciate on longer journeys.

The 812 Superfast, in fact, is aimed at clients that demand the most powerful and exclusive Ferrari in the range. They want a blisteringly high-performance car, but refuse to compromise on the kind of versatility that will allow them to thoroughly appreciate driving it as a 360-degree experience.

Engine and transmission

The challenge Ferrari tackled with the 812 Superfast was to design the most powerful road-going engine in the marque’s history (800 cv, 123 cv/l) whilst contemporaneously cutting fuel consumption and emissions, and, naturally, retaining the inimitable Ferrari 12-cylinder soundtrack.

At the development stage, the engineers set themselves the goal of exceeding the specific power output of the F12berlinetta’s V12 which itself delivered class-topping performance. To do so, they decided to focus their efforts principally on optimising the intake system and combustion efficiency to fully exploit the increase in the engine’s displacement from 6.2 to 6.5 litres. These aspects increased the maximum amount of air that could be drawn into the engine (and thus its power output) thereby boosting its

The development process resulted in a maximum power output of 800 cv at 8,500 rpm, a new benchmark for the Ferrari range, in addition to a specific power output of 123 cv/l, a completely unprecedented figure for an engine front-mounted in a production car.

The torque curve illustrates this impressive improvement on the F12berlinetta in terms of acceleration and instantaneous power, particularly at high revs. The engine’s power is underscored by a full, rich exhaust sound that exploits the acoustic clout delivered by its increased displacement.

These performance levels were achieved in part by optimising the engine design and in part by introducing innovations, such as the use of a 350 bar direct injection system for the very first time on a spark-ignition engine, and the control system for the variable geometry inlet tracts, developed on naturally-aspirated F1 engines, which is a further evolution on its application on the special limited-series F12tdf.

These systems allow the increase in displacement from 6.2 to 6.5 litres to be exploited to maximise power output whilst retaining excellent pick-up even at low revs.

The high pressure injection system also improves nebulisation of the injected fuel thus dramatically reducing the the amount of particulates emitted when the catalytic converter is warming up, ensuring the engine complies with all emissions regulations.

The engine’s maximum power-to-fuel consumption ratio has also been improved, attesting to the engine’s exceptional efficiency in urban driving contexts. This was achieved in part as a result of Stop&Start On the Move strategies which cut and restart the engine while the car is moving.

Particular attention was also paid to calibrating the Manettino settings to enhance the engine’s potential and the sensation of extreme power delivered by the car. That said, the driver will always be able to easily and confidently dose the massive torque available with the accelerator pedal, thanks to smooth, progressive power delivery at all engine speeds.

The result of all these developments is a boost in maximum power output to 800 cv at 8,500 rpm (an impressive 60 cv more than the F12berlinetta) and maximum torque of 718 Nm @ 7,000 rpm - a completely unprecedented achievement for a naturally-aspirated Ferrari production engine.

A significant 80% of maximum torque is available at just 3,500 rpm, improving both flexibility and pick-up at lower revs. The shape of the power curve, which rises constantly all the way to the maximum revs of 8,500 rpm, and the rapidity with which engine speed increases, thanks to low inertia, give occupants the feeling of boundless power and acceleration. The latter sensation comes courtesy of the overall increase in maximum power output and the optimisation of the aforementioned power curve between 6,500 and 8,900 rpm, which maximises the average horse power exploitable for presson track driving when engine revs are kept consistently high.

The exhaust system geometry was evolved to increase and balance the sound from the engine compartment and tailpipes, with a 6-into-1 manifold. The aim being, of course, to enhance the car’s already extreme, sporty character. The resulting engine sound is strong and smooth inside the cabin in all driving conditions.

Transmission

The new 812 Superfast is fitted with Ferrari’s F1 dual-clutch transmission which has been further evolved to meet the car’s track driving performance targets and cope with the boost in maximum revs to 8,900 rpm. The gear ratios on all of the gears have been shortened by an average of 6% to exploit the extra performance and higher revs to the fullest as well as to improve the car’s acceleration without compromising pick-up in higher gears.

There was particular focus on calibrating the gear-shift strategy to enhance the car’s sportiness, further slashing response times and creating a feeling of massive power and speed both in terms of longitudinal acceleration and auditory perception of the rising rpms. In both up- and down-shifts, the transition time has been reduced by 30%. Combined with the shortened gear ratios, these modifications, mean that occupants will instantly feel the car’s powerful response to the throttle.

On the track, this sharpened response equates to more down-shifts in the same time interval, when the driver uses the multi-down function (keeping the steering wheel-mounted Down shift paddle depressed with the Manettino in Sport position).
