Ferrari’s first series production PHEV (Plug-in Hybrid Electric Vehicle), the SF90 Stradale, delivers unprecedented performance for a production car. Figures such as 1,000 cv, and a weight-to-power ratio of 1.57 kg/cv, make it the top-of-the-range model for the first time in the marque’s history. The SF90 Stradale raises the new benchmark for downforce and efficiency in high-performance road cars, thanks to its ability to generate 390kg of downforce at 250 km/h.
The heart of the SF90 Stradale is a 90° V8 turbo engine that delivers 780 cv, the highest power output of any 8-cylinder in Ferrari history. The remaining 220 cv is brought by three electric motors, one at the rear, located between the engine and the new 8-speed dual-clutch transmission on the rear axle, and two on the front axle. The system allows the driver to simply select one of the four power unit modes, and then focus on driving.
The SF90 Stradale is also the first Ferrari sports car to be equipped with 4WD. This allows the incredible power unleashed by the hybrid powertrain to be fully exploited and to achieve the impressive results: 0-100km/h in 2.5 sec and 0-200km/h in just 6.7 seconds.
For the new model, Ferrari’s engineers have developed the full-electric front axle, known as the RAC-e (electronic cornering set-up regulator). Fully integrated into the car’s vehicle dynamics controls, it controls the distribution of torque, making driving on the limit much simpler and easier. The chassis and bodyshell of the SF90 Stradale is all new, built using multi-material technology, including, carbon fibre.
The SF90 Stradale is the first car to feature the new ignition key with full keyless technology and also the first for a Ferrari to use matrix LED headlight technology to improve visibility in all driving conditions thanks to active beam control.
The SF90 Stradale sports a unique architecture: its compact bubble-shaped cabin is located ahead of the mid-mounted engine. The rear of the car is dominated by high exhaust pipes which are the result of optimisation of the exhaust line layout. The low position of the power-train made it possible to lower the car’s tail as well.
A wraparound aeronautically-inspired cockpit demonstrates the symbiotic relationship between car and driver. The central instrument cluster comprises a single 16” digital HD screen which curves towards the driver to make it easier to read. The default screen features a large circular rev counter which is framed by the battery charge indicator. The navigation screen is on one side of the rev counter with the audio control one on the other.
The SF90 Stradale’s steering wheel is fitted with a series of touch commands that let the driver control virtually every aspect of the car without ever taking their hands off the wheel. The traditional controls include the now-classic steering-wheel mounted headlight control, windscreen wipers, indicators and the Manettino for driving modes. The new touch controls are: the compact but functional pad on the right-hand spoke let the driver navigate the central cluster screens, while voice and cruise controls are on the left-hand spoke. The Head Up Display projects various data onto the windshield within the driver’s field of vision.
For the first time on a Ferrari, clients may opt for the standard car and a version with a more sports-oriented specification. The Assetto Fiorano specification includes significant upgrades, like special GT racing-derived Multimatic shock absorbers, extra lightweight features made from high-performance materials such as carbon-fibre (door panels, underbody) and titanium (springs, entire exhaust line), resulting in a weight-saving of 30 kg. Another difference is the high downforce carbon-fibre rear spoiler which generates 390 kg of downforce at 250 km/h. The Assetto Fiorano includes Michelin Pilot Sport Cup2 tires that feature a softer compound and fewer grooves than the standard tires.
