Ferrari FF This is a V 12 four-seat GT model with a front engine, which will not only replace 6 12? Coupe also aims to attract a new group of Ferrari consumers. This new four-seat four-wheel drive FF car was designed by Ferrari's own chief designer flavio? Designed by Pininfarina under the guidance of manzoni. As the first modern Ferrari car that will accommodate four adults and their luggage, this Ferrari FF will be unveiled at the Geneva Motor Show in March 20 1 1 and will be put on sale in the near future. Ferrari hopes that this FF will attract consumers who usually use all-wheel drive cars or SUVs in winter.
Ferrari named the all-wheel drive system adopted by FF as 4RM. This system includes two gearboxes with a total of nine forward gears. The late arrival of all-wheel drive models shows that Ferrari officials have taken a very cautious attitude in launching all-wheel drive models. Is the birth of FF better than Porsche's first Carrera? 4 More than 30 years late.
Ferrari FF all-wheel drive system
There is no doubt that all-wheel drive system can improve handling, but Ferrari's system is not designed to improve the performance of vehicles in dry environment. In the words of Ferrari technical director, the best way to improve the dry handling of sports cars is to transfer all the power to the rear axle. In fact, FF's 4RM all-wheel drive system is also biased towards the rear axle in power transmission. The diameters of the front axle and the rear axle directly show this. The front axle shaft is thinner, so the maximum torque obtained by the front axle only accounts for 20% of the total power output.
Front two-speed gearbox
Ferrari arranged the engine behind the front axle, forming a traditional front center layout. The traditional all-wheel drive system transmits power through two sets of transmission shafts and a gearbox, but this will bring disaster to Ferrari. The extra drive shaft will bring extra weight and affect the spatial layout. Ferrari gave up this technically easier solution and chose another way.
Rear 7- Forward Dual Clutch Transmission
The 4RM system allows the power transmitted to the front axle to be directly transmitted through the gearbox with two forward gears (including one reverse gear) instead of the main gearbox. The familiar 7-speed gearbox is still in the rear axle, responsible for the power transmission of the rear axle. Before understanding this system, many friends may think that two gearboxes are not as heavy as two transmission shafts, which has a greater impact on vehicle performance.
The ordinary gearbox is like this, but the two-speed gearbox on the front axle will not make people feel so worried. This gearbox is integrated with the engine, replacing mechanical parts weighing about 35-40 kilograms. The engine power is directly transmitted from the crankshaft to the front gearbox, and the front gearbox distributes the power to the left and right wheels through the electronically controlled multi-disc clutch. Ferrari FF has no differential on the front axle. The specific working conditions of the front gearbox are as follows: when the main gearbox is at 1 or 2, the gearbox is combined with the first group of transmission gears; When the main gearbox is in the third or fourth gear, the second group of transmission gears of the front gearbox; After the rear gearbox is in 5th gear, the front axle will no longer get power, and all the torque will be transferred to the rear axle.
In most cases, Ferrari FF is still a standard rear-wheel drive supercar. Only when the driving computer calculates that it needs to output power to the front axle will the clutch of the front gearbox be combined. This intelligent all-wheel drive system was independently developed and put into production by Ferrari, and other related components were produced by Italian supplier Carraro. The 4RM system will directly improve the starting performance of the vehicle, and the FF will accelerate from standstill to 100 km/h in only 3.7 seconds. Without this system, it will take longer for the vehicle to complete the same acceleration test.
KIMI is still staying at WRC this year. He himself said earlier that he would never return to F 1, but who knows, he is not in Red Bull Youth Team or Ford now, but has organized a team by himself? It is called team ICE 1, and its full name is "ICE 1? Racing? The world? Rally? "Team, this car is a new Citroen DS3 car.
On Tuesday, kimi raikkonen completed the first test of NASCAR for two days. Raikkonen is in Gresham, Georgia, USA. Motor racing? Park) completed more than 400 laps on the elliptical ring road, and it is said that the test effect is very good.
This test is not open to the public, and no media can take pictures without the permission of the team. We only know KBM (Kyle? Giving? Motorsports provided a black Toyota Tundra racing car, and Raikkonen was tested in a black racing suit.
The news released by KBM team today said: "Raikkonen successfully tested Toyota Tundra on a half-mile track, and the lap speed was very stable. The Finns completed more than 400 laps in two days, and carried out chassis adjustment, shock absorption adjustment and tracking adjustment with the KBM team and Toyota engineers, which made Raikkonen better familiar with the new car. "
On May 20 this year, the Finnish Iceman will make the debut of NASCAR at the Charlotte Circuit in the United States and participate in the NASCAR pickup race.
