Ferrari released the SF9 at the end of last year? Stradale is of extraordinary significance. Thanks to advanced technologies such as plug-in hybrid, it has 1 horsepower, and SF9 has become the fastest mass-produced sports car in Ferrari's history. According to past practice, all kinds of test drive contents have been overwhelming on the Internet for a long time. However, this year's situation is very special. Due to the epidemic, travel restrictions in Europe have not been lifted, and most media outside Europe have not yet touched this car. Although the test drive wish can't be achieved, it doesn't affect us to interpret this car from the theoretical level.
the power of internal combustion engine is 78 HP
in SF9? When Stradale was first introduced, some people criticized Ferrari for not striving for progress, saying that the engine of SF9 imitated F8? Tributo。 In fact, except for the same cylinder block and displacement, the remaining engines of SF9 and F8 are quite different. Ferrari replaced the engine of SF9 with new twin turbines, intake manifold and exhaust manifold, and redesigned cylinder head, crankshaft and piston. This engine is 25kg lighter than the one on F8, and its installation position is 5mm lower. Finally, SF9? Stradale's 3.9T? The V8 engine has a maximum power of 78 HP and a maximum torque of 8Nm, and it is also the fastest turbine engine in the world at present.
the fastest Ferrari sports car
According to the test results officially released by Ferrari, SF9? The -1km/h acceleration time of Stradale is only 2.5 seconds, and the -2km/h acceleration time is 6.7 seconds. This acceleration is on the same level as Koenigsegg One: 1 and McLaren Senna. SF9? Stradale not only surpassed all previous Ferrari sports cars including LaFerrari in a straight line, but also SF9? Stradale's lap speed is one second faster than LaFerrari's.
There is no reverse gear in the gearbox
Thanks to the plug-in hybrid system, Ferrari was able to operate in SF9? The Stradale car is designed smarter and bolder. The reverse function of this car is realized by the reverse rotation of the front wheel motor. The 8-speed dual-clutch gearbox is not designed with reverse gear, so the volume and weight are obviously reduced, which is 1kg lighter than the 7-speed dual-clutch of F8, and the installation position is also 15mm lower, which greatly improves the sportiness of the vehicle.
pure electric power is used for braking
Like other hybrid cars, Ferrari SF9? Stradale's braking system also uses a combination of kinetic energy recovery and physical braking. In order to achieve the optimal state, the brake pedal needs pure electric power. The principle is basically the same as that of the steering wheel, which can improve the braking response speed and reduce the vehicle energy consumption.
It may be surprising that the car body is not carbon fiber
, but Ferrari insists that the aluminum body is the most suitable for this car. SF9? Stradale's body structure consists of F8? Tributo is improved, but the bulkhead between the passenger compartment and the engine is made of carbon fiber, which reduces the weight by 25% and improves the torsional stiffness of the car body by 2%, making the sports potential reach a new level.
you can lose another 1kg
SF9? The standard dry weight of Stradale is 167kg. If the prospective owner is not satisfied with this weight, he can also reduce the body weight by 1kg by selecting lightweight components. These options include carbon fiber wheels and Assetto? Fiorano performance option package and so on. In addition, the owner can also remove the unused door panel storage compartment to achieve the ultimate lightweight.
Easy to drive
See the SF9? After Stradale's performance data, I believe many motorists will be afraid that it will be difficult to get started or easy to get out of control. However, Ferrari official test driver Raffaele? de? Simone said, "It's an easy car to drive. With the previous 488? Compared with Pista, SF9? Stradale has lower requirements for drivers, but it will have a slight oversteer when it is fully fueled. After all, 8 of the 1 horsepower are transmitted to the rear wheels. "
the mechanical instrument is missing
Ferrari SF9? Stradale used a 16-inch full LCD instrument in the car, including the mechanical tachometer located in the center of the dashboard. The operation mode of the instrument is completed through the thumb touchpad on the steering wheel. However, under the steering wheel, Ferrari's traditional red driving mode knob is retained, and the driver can freely switch between four driving modes: eDrive, Hybrid, Performance and Standard through the physical knob while driving.
Lightweight Aerodynamics Kit
Ferrari has always been a master of aerodynamics in the sports car industry. This time, the R&D team gave SF9? Stradale developed a cleverly designed tail and applied for a patent. The rear wing can generate 39kg downforce at a speed of 25km/h, and the tail main body remains stationary. The active adjustment function is realized by descending a small area under the tail. Obviously, the motor that performs the operation can be made smaller and therefore lighter. The aerodynamic parts of the front part are fixed, but there is an S-shaped air duct in the front of the car through the front cover and the vortex generator below. This is the charm of Ferrari's body design. They can always find a simple and lightweight scheme to achieve the best aerodynamic effect.
The first plug-in hybrid Ferrari
Ferrari really didn't do it aggressively enough, because in the LaFerrari era, rival porsche 918? Both Spyder and McLaren P1 have plug-in function. Through this new SF9? Stradale, Ferrari is finally determined to promote the application of plug-in hybrid technology, and V8 plug-in hybrid will gradually replace V12 engine and become the flagship power of Ferrari in the next era.
