Ferrari unveils V12 special series

• New Ferrari V12 special series based on the 812 Superfast

• Launch event live-streamed on Ferrari’s social media channels

• The coupe is flanked by an exclusive Targa version

• New GT Sporting Activities Department near Fiorano track hosts launch

MARANELLO, Italy: The 812 Competizione, the new limited-edition special series car derived from the 812 Superfast, was presented on Wednesday to media, clients and fans all over the world. In the course of the event, which was broadcast live on Ferrari’s social media channels, the wraps were also whipped off the 812 Competizione A, a spectacular Targa-top version, again a limited-series and an homage to the Prancing Horse’s glorious open-top tradition.

The presentation took place in a very special venue, the recently-opened GT Sporting Activities Department located alongside the Fiorano track, further strengthening the inextricable link between Maranello’s road-going sports cars and the peerless racing DNA developed as a result of over seven decades of success on the world’s circuits.

The launch began with the 812 Competizione completing several laps of the circuit to give viewers a full appreciation of the car’s forms in this dynamic and high-performance context in addition, of course, to hear the unmistakable sound of Ferrari’s iconic naturally-aspirated V12. After the hot laps Enrico Galliera, Ferrari’s Chief Marketing & Commercial Officer, officially presented the car and then unveiled the 812 Competizione A.

This duo of cars is dedicated to a very exclusive group of collectors and enthusiasts of the most noble of Ferrari traditions, which focuses on uncompromising maximum performance. The innovative technological concepts applied to the engine, vehicle dynamics and aerodynamics have raised the bar to new heights.

Once behind the wheel of the 812 Competizione and the 812 Competizione A, the driver becomes one with the car, regardless of whether it is on road or track. The car guarantees instantaneous responsiveness to commands and absolute control even in the most complex of manoeuvres. Maximum fun behind the wheel and driving exhilaration are ensured at all speeds, thanks in great part to the new independent, four-wheel steering, which delivers exceptional agility and precision in cornering.

POWERTRAIN

The 812 Competizione and 812 Competizione A sport the most exhilarating V12 on the automotive scene and is derived from the multi-award-winning engine powering the 812 Superfast. The result is a naturally-aspirated 830 cv engine that pairs impressive power with electrifying delivery and the inimitable soundtrack that Ferrari V12 purists know well. To boost the output of the engine, which has the same 6.5-litre displacement as the 812 Superfast’s V12, several areas have been significantly re-engineered to achieve a new record red line while optimising the fluid-dynamics of the intake system and combustion, and reducing internal friction.

Maximum revs are now 9,500 rpm which, together with a rising crescendo of torque delivery, unleashes a feeling of progressive and boundless power and acceleration. A result delivered by the meticulous redesign of key engine components such as the con-rods, pistons, crankshaft and distribution. The titanium con-rods are 40% lighter than steel versions whilst delivering the same mechanical resistance; the piston pins, on the other hand, have been given a diamond-like carbon (DLC) coating to reduce the coefficient of friction to the benefit of performance, fuel consumption and wear. These modifications are combined with a rebalanced crankshaft, which is also 3 per cent lighter than the previous version.

The most significant improvements, however, are to the distribution and the cylinder heads, which have both been completely redesigned. The cam (which now features DLC coating) now actions the valve stems via DLC-coated steel sliding finger followers, which are derived from Ferrari’s F1 experience and were developed specifically for this engine to provide a higher lift profile.

To ensure that the engine breathes correctly across the entire rev range, the intake system was redesigned: both manifold and plenum are now more compact to reduce the overall length of the tracts, thus delivering more power at high revs, while the torque curve is optimised at all engine speeds by a system of variable geometry inlet tracts. This enables the length of the intake tract assembly to be continuously modified, adapting it to the firing order to maximise the dynamic charge in the cylinder. The result is an engine that revs with tremendous speed all the way to the cut off with no drop off towards the red line.

To reduce friction and mechanical losses, thereby improving the engine’s overall efficiency, the engineers developed a new variable-displacement oil pump that continuously adjusts oil pressure across the engine’s entire operating range. Another important point to underscore is the adoption of a less viscous oil (Shell Helix 5W40) than used on previous V12s and the improvement in the flow rate throughout the entire oil scavenge line.

The direct fuel injection management strategy has been further developed to keep abreast with increasingly stringent emissions regulations. The calibration of the timing and amount of fuel injected, as well as an increase in injection pressure, have reduced emissions and the generation of particulate, especially when the engine is cold.

The ignition system is constantly monitored by the ECU which has an ion-sensing system that measures ionising currents to control ignition timing: it has a single and a multi-spark function to the benefit of smooth, flexible torque delivery. The ECU also controls combustion in the chamber to ensure that the engine is always working at peak thermodynamic efficiency, something also achieved in part by a sophisticated strategy that recognises the octane rating of the fuel being used.

To maintain the traditional incredibly high standard of engine sound to which Ferrari V12 owners are accustomed, whilst simultaneously introducing a GPF (Gasoline Particulate Filter) to the exhaust system that ensures compliance with the very latest emissions regulations, the engineers added a new exhaust tailpipe. This unusual and innovative design solution reinstates the medium-high frequency sound muffled by the use of the GPF.

In order to deliver excellent acoustics, performance and aesthetics, the exhaust tailpipes are visible to underscore their function and the car’s track-inspired character without impinging on the signature elegance of all Ferraris. Work was also carried out on the intake tract to which a second pair of resonators were add to enhance specific frequencies and the engine’s more noble combustion order harmonics, creating the perfect melding of the sound from the exhaust and from the intake system.

Both the 812 Competizione and 812 Competizione A are equipped with a seven-speed dual-clutch gearbox, pushing the performance of the latter to new extremes and delivering a new gearshift feeling for the V12. Calibration of the control strategies has reduced shift times by a further 5 percent. Although it retains the same gear ratios as the 812 Superfast, the new car’s changes are even more sporty, thanks to the extra 500 rpm in maximum revs allowed by the new V12.

Hand-in-hand with the performance boost comes further fine-tuning of the cars’ respect of emissions norms with an evolution of the HELE system, which enables an on-the-move Start&Stop function, and

a series of emissions-reducing engine maps, which maintain the signature Ferrari V12 sound even at low speeds. When the HELE is deactivated, performance driving-oriented maps return with lightning-fast gear-shifting for maximum response.

The cooling system has also been adapted to cope with the additional heat generated by the new engine’s extra 30 cv, resulting in the introduction for the very first time on a Ferrari V12 of a single front air intake that maximises the amount air of cooling air channelled towards the radiators. The entire coolant circuit has also been improved, increasing cooling efficiency by 10 percent compared to the 812 Superfast. In addition, the single air intake has been further optimised to improve the fluid dynamics of the engine intake manifold, thereby minimising charge losses along the tract.

Lastly, the engine oil tank was redesigned to cope with the extra flow (up by 30 percent) and to cope with the car’s greater lateral and longitudinal acceleration. Thanks to the optimisation of the interior chambers and volumes, the new tank saves over one kilo of oil compared to the 812 Superfast, making the 812 Competizione and 812 Competizione A the cars that require the least oil in the current V12 range. In the final analysis, this also contributes to the overall reduction in the car’s kerb weight.

AERODYNAMICS

The increase in both the 812 Competizione’s engine output and maximum revs have resulted in a consequent increase in the heat to be dissipated. To meet these new demands, the efficiency of the cooling flow management has been improved without increasing the dimensions and weight of the radiating masses.

While on the 812 Superfast, the engine air intakes are set either side of the large central grille, the 812 Competizione adopts an integrated solution with a single air duct. This allowed the intake for the engine radiators to be extended sideways as far as the chassis allowed as well as reducing not just weight, but also losses to the intake plenum and thus the combustion chamber, which in turn, improved the overall performance.

Compared to the 812 Superfast, the brake cooling concept was completely redesigned around the new front “Aero” calliper which debuted on the SF90 Stradale and which has an air intake integrated into its casting.

Two carbon-fibre side air intakes for the brakes flank the main grille, which feeds cooling air to the engine and cockpit. These intakes are square in section and are split between brake cooling and a double air curtain duct.

Externally the front air intakes are hugged by the scooped side area of the bumper, which extends forwards along its lower edge, defining the shape of the splitter. Two apertures in the wheelarch, one at the top and one at the rear, reduce pressure and enable the underbody to work even more efficiently. The turbulence is channelled and evacuated by the vent rear of the bonnet’s blade, and by that on the wing.

Optimising thermal flows was a fundamental part of developing the 812 Competizione’s front underbody. In fact, the louvres on the bonnet and vents on the front wing meant the size of the vents in the front underbody designed to dissipate hot air coming off the radiators, could be reduced. This translated into a smaller area of the underbody being affected by apertures that would negatively impact downforce generation. The end result was a higher level of downforce at the front and a more energised flow striking the rear of the car.

The modifications made to the braking system also enabled the engineers to redesign the front underbody to extend it into the wheelarch well. The new layout, which freed up space around the lower front wishbone, made it possible to extend the surface area that could be used to generate downforce. It also allowed the insertion of a new S-shaped side vortex generator crafted specifically in the wind tunnel to improve the lateral expansion of the vortex generated and ensure it works in synergy with the front diffuser. The geometry of the latter was also optimised and can now generate even more downforce than the 812 Superfast as well as improving cooling of the calliper. Taken together these solutions hail a significant improvement in performance: optimising the air vents contributes to a 30 per cent increase in overall front downforce while the new side vortex generator adds a further 40 per cent.

The 812 Competizione’s distinctive tail-end treatment incorporates a number of innovative engineering solutions regarding the exhaust layout, diffuser geometry, spoiler volume, patented rear screen and the bumper design. The rear diffuser extends right across the full width of the car to guarantee maximum horizontal expansion of the underbody’s aerodynamic flows and hails a distinct break with the solution seen on the 812 Superfast.

The silencers and tailpipes have been completely re-engineered: from a classic set up of two circular tailpipes each side of the bumper there is now a single exhaust pipe with an unprecedented vertical rectangular form.

Overall, the rear diffuser development produced an increase in downforce that equates to 25 percent of the total increase compared to the 812 Superfast. This jumps to 35 percent if the contribution of the exhausts blowing into the wake is also taken into account. The rear underbody, on the other hand, is responsible for a 10 percent increase in rear downforce.

The aerodynamic development of the diffuser forms allowed the areas of the car dedicated to downforce generation to be extended transversely. The spoiler is now not only higher than on the 812 Superfast, but extends across almost the entire width of the car, working in perfect aerodynamic synergy with the diffuser to guarantee maximum downforce possible over the rear axle. The redesign of the rear wings also benefits aerodynamic performance: the volume has been scooped out rear of the crest to create an aerodynamic channel in the flank to the outside edge of the spoiler which is thus struck by a highly energised flow.

But what really captures the attention is the rear screen which, for the first time on a production car, is completely closed and thus allowed the engineers to explore some unprecedented aerodynamic solutions. It has been equipped with three pairs of profiled elements which protrude from its surface and act as vortex generators. From the LaFerrari onwards, vortex generators of this type have been used on production cars to maximise downforce generated by the flat underbody. However, this solution was applied to the rear screen on the 812 Competizione to distort the flow and thus redistribute the rear axle’s pressure field.

These vortex generators further enhance the work of the rear spoiler-diffuser system, creating areas of strong pressure gradients in the flow immediately above the rear screen and generating vortexes on the transverse plane. Thanks to this solution, part of the flow is deflected towards the sides of the spoiler which boosts downforce generation, benefiting the efficiency of the diffuser. The patented vortex generators alone guarantee 10 percent of the total increase in rear downforce compared to the 812 Superfast.

Occupant comfort in the open configuration is ensured by the introduction of a flap integrated into the windscreen header rail which deflects the energised, incident flow upwards avoiding that it disturbs the interior. This extends the bubble that covers the entire length of the cockpit, thereby also avoiding irritating excess pressure in the area behind the occupants’ heads.

Two aerodynamic apertures have been created between the two buttresses to manage the flow entering over the side windows and to force it to follow a specific route, a fundamental factor in reducing both pressure inside the cabin and the instability of the flow itself. The result of this strategy is twofold because, aside from improving comfort, it also increases aerodynamic efficiency by making the flow stable even when the top is open.

VEHICLE DYNAMICS

The guidelines in the development of the812 Competizione performance strategy were to boost overall performance levels, improve driving pleasure in lateral dynamics and a specific focus on the handling characteristics of a special version.

The 812 Competizione debuts many innovative components and contents, which have ensured it delivers on its vehicle dynamics performance targets. Specifically, these include the first use of independent four-wheel steering, the evolution of the Side Slip Control (SSC) system to version 7.0, and the development of the dedicated new Michelin Cup2R tyres.

The independent rear-wheel steering features a new electronic management system that enables the right and left actuators to be actioned individually rather than synchronised. This evolution yields a significant boost in performance in relation to the control of the position demanded of the individual actuators, and quicker response times.

This system emphasises the front axle’s response to steering wheel commands, maintaining the feeling of grip from the rear axle, which responds promptly to front inputs, and also manages the car’s lateral dynamics response more efficiently as a function of the actuation frequency of the steering wheel angle.

The new solution has resulted in the evolution of the SSC system which brings together all of the control systems developed in-house and uses a shared dynamic control language to integrate the actions of all of the systems to improve efficiency. The Side Slip Control 7.0 spans the electronic differential (E-Diff 3.0), traction control (F1-Trac), SCM-Frs magnetorheological suspension control, brake pressure control when driving on the limit (FDE) available in Race and CT-Off Manettino settings,

and the Virtual Short Wheelbase 3.0 which integrates the electric front steering with the electronically controlled independent rear-wheel steering.

All-carbon-fibre rims are also being made available for the very first time on a Ferrari V12 and offer a total weight reduction of 3.7 kg compared to the lightweight forged 812 Superfast wheels. The inside of the channel and of the spokes is coated in a layer of white aerospace-derived paint that reflects and dissipates heat produced by the car’s extremely efficient braking system, guaranteeing consistent performance over time even under hard use on the track.
