Sina Auto News On October 29, 2019, Ferrari’s first mass-produced plug-in hybrid sports car, SF90 Stradale, was officially unveiled in China, and the price was announced at 3.988 million yuan. The new car is positioned as a flagship supercar, equipped with a hybrid system consisting of a 4.0T V8 turbocharged engine and three motors, with a maximum power of 1000Ps, a speed of 0-100km/h of only 2.5s and a maximum speed of over 340km/h..
1. Ferrari’s first externally rechargeable hybrid vehicle;
2. The maximum power of the hybrid system reaches 1000Ps, and it consists of a 4.0T V8 turbocharged engine and three motors;
3, 0-100km/h only takes 2.5s, and the maximum speed exceeds 340 km/h.
The F90 Stradale was built by a team of designers from Flavio Manzoni and Ferrari Styling Centre. The compact rear suspension, which is shorter than the front suspension, and the forward movement of the cockpit create a forward-leaning structure of the cockpit, highlighting the characteristics of the mid-engine The low center of gravity enables designers to reduce the cockpit area by 20 mm. Combined with the curved windshield, slender A-pillar and wide tread, it forms a fashionable car with perfect proportion. The compact bubble cockpit is like an aviation cockpit, and the design of moving forward greatly further highlights the tail flying arch shape in the same color as the car body.
The prominent feature of the rear of the vehicle is the high exhaust pipe, which is the result of optimizing the exhaust pipe layout. Because the position of transmission system in sports car is much lower than in the past, designers can reduce the height of the rear of the car. Another feature different from the traditional coupe is that the rear bumper no longer follows the line from the roof to the rear bumper. The baffle separated from the cooling grille embodies the separated modeling elements. The taillights also changed Ferrari’s iconic oval shape. The striking horizontal luminous ring makes the taillight more horizontal and reduces the visual height of the rear.
The interior of SF90 Stradale aims to create a cockpit that leads the new design direction, and will continue to be used in all Ferrari cars in the future. Designers have integrated future elements into the operation interface, created a wraparound cockpit inspired by aviation and highlighted the dashboard, and adopted a fully digital man-machine interface. This is the first time Ferrari has used a 16-inch digital high-definition screen tilted to the driver’s side in the central instrument cluster, which is easy for the driver to see, and adopts a F1-style surround cockpit. This is the first time that such screens have been used in Ferrari mass production sports cars.
The concept of "keeping an eye on the road and holding the steering wheel" has been promoting the continuous development of the man-machine interface of every Ferrari F1 racing car, and then gradually transferred to the road sports car version. The steering wheel of SF90 Stradale has been transplanted from the track perfectly, and a series of touch commands have been introduced, so that the driver’s hands can control all parts of the sports car without leaving the steering wheel, opening a new era of control. Traditional control devices include headlight controller on steering wheel, windshield wiper, signal lamp and classic Manettino driving mode.
In addition to the man-machine interface with a new concept, another obvious change in the cockpit is the design of the central control area. The slender shape is lined with control buttons from F1, which is probably the most classic design element in recent generations of Ferrari models. All of them have been redesigned, supplemented by modern metal panels, which can not help but remind people of the same classic prancing horse design, traditional shift lever.
For the first time, Ferrari offers two versions for customers to choose from, including the standard version and more sporty configuration. The Assetto Fiorano configuration model adopts a greatly optimized and upgraded configuration, including a special multi-modal shock absorber based on GT racing car, as well as lightweight parts made of high-performance materials such as carbon fiber materials (doors, floor) and titanium materials (springs, complete exhaust pipes), which successfully reduced the body weight by 30 kg. Other differences include the carbon fiber rear spoiler, which can generate 390 kilograms of downforce when the speed reaches 250 kilometers per hour. The Assetto Fiorano model is equipped with Michelin Pilot Sport Cup second-generation tires specially designed to improve the performance on dry roads on the track. Compared with the tires used in the standard model, the tread texture is softer and the surface grooves are less.
SF90 Stradale is Ferrari’s first plug-in hybrid vehicle. The power system consists of a 4.0T V8 turbocharged engine and three motors, of which two motors are installed on the front axle and can work independently, and the third motor is installed at the rear of the vehicle between the engine and the gearbox. The maximum output power of this hybrid system is as high as 1000Ps.
The 7.9kWh high-performance lithium-ion battery supplies power to three motors, which ensures that in eDrive pure electric mode, only the front axle motor can be started to meet the cruising range requirement of 25 kilometers. When the engine stops working, two independent motors will help the new car achieve a speed of up to 135 km/h and a maximum longitudinal acceleration of no more than 0.4 g. Reverse gear can only be used in eDrive mode, which also means that the new car can drive at a low speed without starting the V8 engine. The organic integration of front-axle motor and ejection starting technology helps this brand-new sports car to accelerate at 0-100km/h in only 2.5s, and at 0-200km/h in only 6.7s.
Through the new eManettino control knob installed on the steering wheel, the driver can freely switch between four different power control modes: eDrive, Hybrid, Performance and Qualifying. "eDrive mode" is suitable for congested urban road conditions, and the system will be driven by electricity as much as possible; The default "hybrid power mode" can realize the optimal presentation of system energy efficiency through power distribution; In the "performance mode", the engine is always working, and more emphasis is placed on charging the battery, rather than optimizing efficiency, in order to bring the driver a freewheeling driving experience; "Qualifying mode" can realize the maximum power output and release the motor output power to the maximum extent.
In terms of transmission, SF90 Stradale is matched with an 8-speed wet dual-clutch gearbox and adopts a four-wheel drive system. In addition, the new car also provides an electronic traction control system, a brake-by-wire system with anti-lock braking and electronic braking force distribution, and a torque vector distribution system, which optimizes the overall grip of the vehicle and brings stronger and more balanced performance.
Ferrari SF90 Stradale with beautiful proportion and strong performance will open a new chapter in the electrification transformation of Ferrari brand. Although the engine is still the main output unit of the whole plug-in hybrid system in terms of power parameters, the formed multi-motor hybrid system architecture and control system are the foundation of Ferrari’s future deeply electrified models.
