The Most powerful Ferrari and arguably the most beautiful gets its world premiere at Geneva.

Most powerful ever 800 cv production engine
Ferrari has selected the 87th edition of the Geneva International Motor Show for the world premiere of the new 12-cylinder berlinetta, the 812 Superfast, the most powerful and fastest Ferrari in the marque’s history.
This new car not only introduces a plethora of innovative features but is also particularly significant as the V12 series marked the official start of the glorious Prancing Horse story in 1947, 70 years ago this year.     
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. 
It is aimed at clients demanding the most powerful and exclusive Ferrari in the range: an uncompromising sports car that will deliver exhilarating driving both on road and track yet also be comfortable enough to allow its owners enjoy it as an all-round experience.
Engine
Powered by a new 6.5-litre V12 engine that unleashes 800 cv, the 812 Superfast is the new benchmark in the mid-front-engined sports car segment, achieving maximum power output at 8,500 rpm, which translates to a specific power output of 123 cv/l. Figures that no other front-engined production car has ever even come near to delivering and which ensure the kind of thrilling top-end performance that is the exclusive characteristic of Ferrari’s noble V12 heritage.
The engine’s power is underscored by a full, rich exhaust sound that exploits the acoustic clout delivered by its increased displacement.
Maximum torque is 718 Nm @ 7,000 rpm, a significant 80% of which is already available at 3,500 rpm, improving both driveability and pick-up even at low revs.
These performance levels were achieved in part by adopting a 350 bar direct injection system for the very first time on a high-performance engine and pairing it with variable geometry intake tracts conceptually derived from those of naturally-aspirated F1 engines.  
The 812 Superfast’s dual-clutch transmission has specific gear ratios which, combined with shorter up and down-shifting times between gears, sharpen throttle response still further.  
Vehicle dynamics
The 812 Superfast is equipped with leading-edge control systems and components, resulting in unparalleled handling and roadholding.  It’s the first Ferrari to sport EPS (Electric Power Steering) which, in accordance with Ferrari’s uncompromising engineering approach, is used to fully exploit the potential of the car’s performance and, through the complete integration with all the electronic vehicle dynamics controls – including the latest 5.0 version of Ferrari’s patented Side Slip Control (SSC) - make its powerful performance easier to handle and even more thrilling to exploit.
The vehicle controls also feature, for the first time, the Virtual Short Wheelbase 2.0 system (PCV) which, following the experience gained with the F12tdf, features a further evolution of the software that improves the nimbleness of the handling and reduces the vehicle response times even further.
Styling and aerodynamics
Designed by the Ferrari Styling Centre, the new 812 Superfast redefines the formal language of front-engined V12 Ferraris, underlining the car’s exceptional performance with very sporty lines and proportions.  
Seen in silhouette, the 812 Superfast has a fastback sleekness: a two-box design with a high tail reminiscent of the glorious 365 GTB4 of 1969. The design of the flanks visually shortens the tail and is characterised by impressively muscular wheelarches which imbue the 812 Superfast with the power and aggression warranted by its imposing V12. Full-LED headlights integrated into the design of the sculpted air intakes on the bonnet also emphasise that front muscle, integrating with, and wrapping around the front wheelarch.
At the rear, four round tail-lights inspired by Ferrari tradition emphasise a design crafted around horizontal lines and give the 812 Superfast a broad, imposing stance, visually lowering both spoiler and cabin. 
The car is being launched in a special new colour, Rosso Settanta, which marks the company’s 70thanniversary.
As with all Ferraris, style and aerodynamic function are seamlessly integrated to produce innovative solutions and forms. Two examples are the multi-functional frontal section, which incorporates a cluster of aerodynamic solutions including active flaps at the front of the underbody, and the rear flank which features an unprecedented aerodynamic by-pass to increase downforce.
Interior
The interior of the 812 Superfast has been revisited in line with the more extreme exterior whilst maintaining unaltered the exceptional on-board comfort and space that Ferrari’s front-engined V12 berlinettas have always offered.
The cabin has been given a sportier, more radical look with the main elements seeming to float, creating an effect of both thoroughbred racing eagerness and lean elegance. The horizontal dash loops stylishly around the central air vents for a sophisticated, sculptural look.
New, more sporty and ergonomic seats feature alongside the new HMI, including new steering wheel and instrument clusters and the latest infotainment and air-conditioning units.

PARIS - Ferrari launches the first four seater in the brands history, the World Premiere of the GTC4Lusso T.

  • The first Ferrari V8-engined four-seater
  • World Premier of the GTC4Lusso T at the Paris Motor Show

Following on from the success of GTC4Lusso, which raised the performance bar for Ferrari’s traditional four-seater  V12 GTs, the Prancing Horse announces the arrival of the new GTC4Lusso T, the first four-seater to be powered by a V8 engine. 
Ushering in a whole new Ferrari Grand Touring concept, the car is aimed at drivers seeking a car that is sporty and versatile, as well as perfect for driving on a daily basis.
The new GTC4Lusso T is equipped with an evolution of the 3.9-litre V8 turbo which punches out a maximum of 610 cv at 7,500 rpm, guaranteeing powerful acceleration with maximum torque of 760 Nm available between 3,000 and 5,250 rpm. Despite such impressive performance, the GTC4Lusso T’s fuel consumption figures guarantee extended range, ideal for town driving or long trips.

Combining this powertrain with rear-wheel drive has resulted in significant weight-saving. Adding four-wheel steering to the mix gives the car additional agility and quicker responses. The rear-wheel steering system is integrated with the latest evolution of the electronic controls of the SCM-E suspension, ESP 9.0 and third generation Side Slip Control (SSC3).
ENGINE
Like every engine to come out of Maranello, the GTC4Lusso T’s V8 turbo has all the classic Ferrari power unit qualities: razor-sharp throttle response, blistering performance, continuous and powerful acceleration at all speeds, an exhilarating soundtrack and compact dimensions. Mounted low down in the chassis, it helps sharpen driving dynamics.
The car’s V8 is the latest evolution to emerge from the engine family that was named the 2016 International Engine of the Year. The 3,855 cc power unit is both compact and efficient, developing 610 cv at 7,500 rpm, resulting in a specific power output of 158 cv/l, the highest in its category. It is also responds instantaneously to the throttle delivering increasingly powerful acceleration (760 Nm of maximum torque between 3,000 and 5,250 rpm) while optimising fuel consumption.
This class-leading performance is achieved by the adoption of new pistons and con-rods in high-resistance aluminium alloy to maximise pressure inside the combustion chamber, new more linear high- and low-pressure air ducts in the intake system to minimise losses and a new intercooler to increase air cooling and minimise fluid-dynamic losses. 
The instant throttle response typical of Ferrari V8 engines is guaranteed by a flat-plane crankshaft, compact turbines featuring twin-scroll technology and a three-piece cast exhaust manifold and turbo housing, the former with equal-length pipes to optimise pressure waves in the turbine.
The car’s excellent performance across the entire rev range, on the other hand, is the result of intensive research into maximising combustion efficiency. The solutions adopted include high-tumble intake manifolds, specifically shaped to improve air entry to the combustion chamber, an ion-sensing system with adaptive ignition and multi-spark functionality which optimises combustion both under high and partial loads across the engine’s rev range. Optimised mechanical efficiency is guaranteed by a variable-displacement oil pump that supplies oil at either high pressure or low pressure, reducing the hydraulic power requirements by up to 30 per cent compared to a conventional pump, and a valvetrain with roller finger followers to reduce the power absorbed by 10 per cent at low revs.
One of most innovative features of the GTC4Lusso T’s V8 is Variable Boost Management, a control software that adjusts torque delivery to suit the gear selected, delivering increasingly powerful pick-up as revs rise, whilst optimising fuel consumption. And all without impinging on driving pleasure. As the car goes up through the gears (from 3rd to 7th), the amount of torque delivered by the engine increases all the way up to 760 Nm in 7th gear. This has allowed Ferrari to adopt longer gear ratios in the higher gears to the benefit of fuel consumption (the car’s range is, in fact 30 per cent more than the V12-engined model).
In line with the finest Ferrari tradition, the GTC4Lusso T has been given its own unique and utterly unmistakable soundtrack. In addition to the flat-plane crankshaft, which synchronises engine firing, and equal-length exhaust headers which equalise the sound, the exhaust line now features a new central section along with a larger-diameter silencer. 
VEHICLE DYNAMICS
When Ferrari’s engineers decided to adopt a V8 turbo engine and rear-wheel drive for the GTC4Lusso T, their aim was to modify the vehicle dynamics to give a sportier feel that was coherent with the handling characteristics laid down by the V12 version. A combination of the car’s lighter overall weight and increased weight bias towards the rear (46:54%) allowed the adoption of a specific set-up for the 4WS and SCM – E control systems. These ad hoc vehicle dynamic control systems ensure the GTC4Lusso T feels more nimble and has reduced roll. The feeling of longitudinal performance is enhanced at low speeds by Variable Boost Management.
In press-on driving, the 4WS (rear-wheel steering) helps provide a sharper response to steering wheel inputs, both entering and exiting corners, thanks to the fact that the rear wheels steer in the same direction as the front ones.
The Magnaride SCM-E damper control system is the same as on the GTC4Lusso and represents the state-of-the-art in control algorithm development. On the GTC4Lusso T, body control is governed by a control model adapted to the new car’s weight distribution and suspension characteristics, and which optimises the tyre contact based on the sensitivity to vertical frequencies.
The response time between front and rear axles has been cut by 6.5 per cent while the steering wheel activity is down 2.5 per cent. As with the  GTC4Lusso, the rear-wheel steering makes it easier for the car to be driven on the limit by making the latter more predictable and easier to control. 
The Side Slip Control 3.0 (SSC3) system dialogues with all the GTC4Lusso T’s components and vehicle dynamics controls. It is thus able to adapt the car’s behaviour to suit differing dynamic and grip conditions. Through the information it receives from all the body sensors and the grip estimation, the SSC3 delivers a real-time estimate of side slip to all onboard systems, which means the car’s behaviour is more precisely tailored to the various dynamic situations it encounters.
The integration of the F1-Trac and E-Diff electronic differential optimises traction and torque delivery to the outside and inside rear wheels. This system also makes the car more driveable on medium grip surfaces. 
The five Manettino positions (Ice, Wet, Comfort, Sport, ESC OFF) underscore the potential of the car’s architecture and vehicle dynamics controls, particularly the rear-wheel steering and electronic differential (E-Diff). The combined effect of the two systems is that torque is efficiently split between the two rear wheels, controlling slip when the rear wheels are on mixed grip surfaces. The rear-wheel steering makes turning in, cornering and exiting corners more effortless, by making yaw angle more predictable with an instant reduction in the amount of steering wheel correction needed and its frequency. 
DESIGN
Designed by Ferrari’s Styling Centre, the GTC4Lusso T maintains the same innovative take on the shooting brake coupé as the V12 version, reinterpreting the concept with an extremely streamlined, tapered shape that gives it an almost fastback-like silhouette. The cabin is an effortless melding of sophisticated elegance – seen in the artisan quality of the prestigious hides - and the high-tech, sporty aspect of the metal or carbon-fibre components mainly found in the human-machine interfaces.
The GTC4Lusso T features the unique Dual Cockpit architecture, designed to enhance the shared driving experience for both driver and passenger. It also incorporates the latest iteration of the infotainment system complete with an impressive 10.25” HD capacitive touchscreen. 
Available to order are specific tailpipes and 20” forged wheels developed especially for the V8 model with a very dynamic design.
