Engine
The Ferrari FF has the largest capacity road-going Ferrari engine ever produced: a 6,262 cc (6.3 L; 382.1 cu in) naturally aspirated direct injected 65° V12, which produces 660 PS (485 kW; 651 hp) at 8,000 rpm and 683 N·m (504 lb·ft) of torque at 6000 rpm.[2]Transmission
The FF is equipped with a 7-speed double-clutch semi-automatic paddle shift system similar to the California and 458 Italia.[1]Four wheel drive system
The new four-wheel drive system, engineered and patented by Ferrari, is called 4RM: it is around 50% lighter than a conventional system, and provides power intelligently to each of the four wheels as needed.[3] It only functions when the manettino dial on the steering wheel is in the "comfort" or "snow" positions, leaving the car most often in the traditional rear wheel drive layout.[10]Ferrari first use of 4RM was in a prototype created in the end of the 80s, called 408 4RM (4.0 liter, 8 cylinder, 4 Ruote Motrici, four-wheel drive).[11][12]
This system is based around a second, simple, gearbox (gears and other components built by Carraro), taking power from the front of the engine. This gearbox (designated "power take off unit", or PTU) has only two forward gears (2nd and 4th) plus reverse (with gear ratios 6% taller than the corresponding ratios in the main gearbox), so the system is only active in 1st to 4th gears. The connection between this gearbox and each front wheel is via independent haldex-type clutches, without a differential.[13] Due to the difference in ratios "the clutches continually slip"[14] and only transmit, at most, 20% of the engine's torque. A detailed description of the system (based on a conversation with Roberto Fedeli, Ferrari's technical director) has been published.[10]
Design
Exterior
The FF shares the design language of contemporary Ferraris, including the pulled-back headlights of the 458 Italia, and the twin circular taillights seen on the 458 as well as the 599 GTB Fiorano. Designed under the direction of Lowie Vermeersch, former Design Director at Pininfarina, work on the shooting brake concept initially started following the creation of the Sintesi show car of 2007.[15] Distinctive styling elements include a large egg-crate grille, defined side skirts, and four exhaust tips. The shooting brake configuration is a departure from the conventional wedge shape of modern Ferraris, and the FF has been likened to the similarly-shaped 1962 Ferrari 250 GT SWB Drogo race car.Interior
The combination of hatchback-like shooting-brake design and collapsible rear seats gives the Ferrari FF a boot capacity of between 450 litres (16 cu ft) to 800 litres (28 cu ft)Engine
The F12berlinetta uses a 6,262 cc (382 cu in), naturally aspirated 65° V12 engine shared with the Ferrari FF, producing 740 PS (544 kW; 730 hp) at 8500 rpm and 690 N·m (509 lb·ft) of torque at 6000 rpm, making it the most powerful road-legal Ferrari to date. This allows the F12berlinetta to accelerate from 0 to 100 km/h (62 mph) in 3.1 seconds, 0 to 200 km/h (120 mph) in 8.5 seconds to a top speed of over 340 km/h (210 mph).[1][2]The engine of the F12berlinetta has been designed to be more efficient than that of the 599, as well as more powerful. The engine management system is fitted with Ferrari's HELE start-stop system to reduce fuel consumption when idling. Ferrari reports that the F12berlinetta can achieve 18 mpg-imp (15.7 L/100 km; 15.0 mpg-US) – a 30% improvement over the 599 – and produces CO2 emissions of 350 g/km.[4]
Transmission
In common with the California, 458 Italia and FF, the F12berlinetta transmits power through a 7-speed dual-clutch automated semi-automatic gearbox operated by the driver using 'paddles' behind the steering wheel. Compared to similar models, the F12berlinetta uses shortened gear ratios to match the power of the engine.[2][3]Chassis
The F12berlinetta is built around an aluminium space frame chassis co-developed with Scaglietti. The chassis is made up of 12 different aluminium alloys and improves structural rigidity by 20% over the 599, whilst reducing weight by 70 kg (150 lb). The centre of gravity has been lowered by around 25 mm (0.98 in). The F12berlinetta's weight distribution is 46% front, 54% rear.[1][3][4]Similarly to other contemporary Ferrari models, the F12berlinetta uses Ferrari's third generation CCM3 carbon ceramic disc brakes with ABS, SCM-E magnetorheological suspension, an electronic limited slip differential, ESP Premium stability control and F1-Trac traction control. The car's stability and traction control, suspension and other settings are controlled by the Manettino dial mounted on the steering wheel.[3]
Tyres
The F12berlinetta is fitted with Michelin Pilot Super Sport tyres, with the tyre codes 255/35ZR20 at the front and 315/35ZR20 at the rear.[5]
