Ferrari F12 Berlinetta: Presentado oficialmente

El recién presentado Ferrari F12 Berlinetta viene para demostrar de que Ferrari siguie siendo el rey en cuanto a la fabricación de motores V12 de altas prestaciones, si recientemente perdió el trono por culpa del V12  de 700 CV que equipa el último Lamborghini, Ferrari vuelve a subir el listón, en esta ocasión con una potencia de 740 CV lo que lo convierte en el Ferrari de producción mas potente jamás fabricado.

Con semejante potencia el F12 Berlinetta ofrece una aceleración de 0 a 100 km/h en 3,1 segundos, la velocidad máxima se sitúa en 340 km/h y en las pruebas realizadas pudo completar una vuelta al circuito de Fiorano en 1:23, lo que se considera como un récord para un Ferrari de producción, mas teniendo en cuenta que el mismísimo Ferrari Enzo necesitaba el tiempo de 1:24 para completar dicho trazado.

Para lograr este magnífico resultado, el F12 Berlinetta cuenta con un cetro de gravedad mas bajo y mas centrado gracias a unas suspensiones y caja de cambios rediseñadas , de este modo a pesar de tener el motor en una posición central/delantera, el 54% de la masa del vehículo se encuentra suspendida en el eje trasero. La aerodinámica también ha sido intensamente estudiada obteniendo un coeficiente aerodinámico de 0,299 Cx, a pesar de ello se ha incrementado en un 76% la downforce.

En cuanto al motor contamos, como ya era de esperar, con un V12 atmosférico de 6.3 litros de cilindrada (para ser exactos 6.262 centímetros cúbicos) de inyección directa de gasolina, el cual logra una potencia de 740 CV y un par de 690 Nm, entregando ya el 80% del par desde las 2.500 rpm y alcanzando el máximo a las 8.700 rpm. El nuevo motor también logra homologar un consumo bastante contenido, situando la cifra en 15l/100 km.

El F12 también ha logrado adelgazar en la báscula unos 70 kg respecto al 599 GTB Fiorano, situándolo en 1.525 kg y marcando una relación de peso-potencia de 2.1 kg/cv. Con esta relación de peso-potencia logra hacer el 0-100 km/h en 3,1 segundos y 8,5 segundos para alcanzar los 200 km/h desde parado.

El nuevo Ferrari cuenta con un chasis completamente nuevo realizado en aluminio tridimensional. La nueva caja de cambios es de doble embrague con 7 velocidades. En el apartado de los frenos, como era de esperar, cuenta con discos carbocerámicos que ya va siendo poco a poco un elemento habitual en todos los deportivos de gama alta.

Announcing the F12berlinetta: the fastest Ferrari ever built
The first in a new generation of V12 cars unveiled exclusively on www.ferrari.com

Maranello, 29th February 2012 – Today’s on-line unveiling of the F12berlinetta ushers in a new generation of Ferrari 12-cylinders in the form of a car that delivers unprecedented performance from an exceptional new engine, combined with innovative design that redefines classic themes along with extreme aerodynamics.

Revealed to the world for the first time on Ferrari.com in preparation for its official debut at the Geneva International Motor Show, the F12berlinetta, finished in an attractive new Rosso Berlinetta three-layer colour, represents the very cutting-edge of mid-front-engined sports cars.

This is, in fact, the most powerful and high-performance Ferrari road car ever launched thanks to the incredibly efficient engine – in terms of mechanical, combustion and fluid-dynamics efficiency – which, together with advanced vehicle architecture, aerodynamics, components and electronic controls, guarantee unsurpassed driving involvement whatever the road or track.

Ferrari’s traditional transaxle layout has been revolutionised to match the more extreme performance of the car. The wheelbase has been shortened and the engine, dashboard and seats have been lowered in the chassis, while the new layout of the rear suspension and gearbox enabled Ferrari’s engineers to make the rear volume of the car smaller. The overall result is a very compact car with a lower centre of gravity that is further back in the chassis, and a level of aerodynamic efficiency that sets new standards.

Scaglietti, renowned for its expertise in aluminium materials and construction, designed an all-new spaceframe chassis and bodyshell using 12 different kinds of alloys, some of which have been used here for the first time in the automotive sector, and employing new assembly and joining techniques. This has resulted in a 20 per cent increase in structural rigidity while reducing weight to just 1525 kg (70 kg less than the previous V12 coupé) with an ideal distribution between the axles (54 per cent over the rear).

The F12berlinetta’s 6262cc 65° V12 engine delivers unprecedented performance and revs for a naturally-aspirated 12-cylinder. Its maximum power output is 740 CV which translates to a specific output of 118 CV/l. Torque reaches a peak of 690 Nm, 80 per cent of which is already available at just 2,500 rpm, and which provides an unrelenting surge of acceleration all the way to the 8,700 rpm limit. The engine is mated to the F1 dual-clutch transmission, which has closer gear ratios developed specifically for this car’s performance. The F12berlinetta boasts a weight-to-power ratio of just 2.1 kg/CV .

Fuel consumption has been reduced by 30%, with CO2 emissions of just 350 g/km – figures which put the F12berlinetta at the top of the high-performance league. These results have been obtained by extensive research and development which focused on efficiencies of the whole vehicle: engine, aerodynamics, tyres and weights.

Similarly excellent results have been obtained with the car’s aerodynamic development, thanks to the integration of the design process with extensive computational fluid dynamics (CFD) simulations and lengthy testing in the wind tunnel. Downforce has been boosted by 76 per cent (123 kg at 200 km/h) while drag has been significantly reduced (the Cd is just 0.299). These results come courtesy of two new solutions. The first of these is the Aero Bridge which uses the bonnet to generate downforce by channelling air away from the upper part of the car to its flanks where it interacts with the wake from the wheel wells to decrease drag. The second is Active Brake Cooling, a system that opens guide vanes to the brake cooling ducts only at high operating temperatures, again reducing drag.

The F12berlinetta’s impressive technical specifications are completed by Ferrari’s latest generation carbon-ceramic brakes (CCM3) and the evolution of the magnetorheological suspension control system (SCM-E). As is now traditional with all Ferraris, its control systems (E-Diff, ESP Premium, F1-Trac, and high-performance ABS) are all fully integrated.

The result is that the new Prancing Horse 12-cylinder accelerates from 0-100 km/h in 3.1 seconds and from 0 to 200 km/h in 8.5 seconds. It also completes a lap of the Fiorano circuit in 1’23», faster than any other Ferrari road car. Benchmark performance and maximum driving involvement are guaranteed by immediate turn-in, with smaller steering wheel angles, and increased cornering speed. Stopping distances have also been drastically reduced.

The design of the F12berlinetta is a result of the collaboration between the Ferrari Styling Centre and Pininfarina and is a perfect balance of uncompromising aerodynamics with harmonious proportions interpreting the typical elements of Ferrari’s front-engined V12 cars in an original and innovative way. A coupé with sleek, aggressive lines whose compact exterior dimensions conceal exceptional in-car space and comfort. The all-new Frau leather interior highlights the balance of advanced technology and sophisticated, handcrafted detailing. In the middle of the light and lean dashboard, there are new carbon fibre and aluminium air vents clearly inspired by the aeronautic field.

The cabin has been optimised to ensure maximum usability of the interior space with additional luggage capacity behind the seats, which can also be easily reached thanks to the large aperture offered by the tail-gate. With the cockpit designed around the driver, typical of all Ferraris, the Human Machine Interface approach is emphasised, grouping all the major commands within immediate reach to guarantee maximum ergonomics for the most involving driving experience.
