The car is Ferrari’s first full series production plug-in hybrid vehicle (PHEV), and also the first of its V8, mid-engined sports cars to use a four-wheel drive system. It uses a hybrid petrol-electric powertrain, with a bored out, four-liter, 769hp variant of its award-winning twin-turbo V8 paired to a trio of electric motors.
Two of the motors drive each of the front wheels independently. This means that when running in pure electric mode, at speeds up to 84mph, the SF90 Stradale becomes a front-wheel drive car for the first time in Ferrari history. Unusually, these motors also control the car’s reversing function, meaning that Ferrari could eliminate a reverse gear from the car’s new, eight-speed gearbox to save weight.
A third motor sits between the ICE and the gearbox. This acts just like the MGU-K system in Ferrari’s racing SF90. Combined power output from all three motors in “performance” mode is 217hp, giving the car a complete system output of 986hp, and 663lbft of torque.
The 7.9kWh battery pack and motors do put a significant amount of weight into the car. In total, the electronics come in at a meaty 600lb, so Ferrari has had to come up with some solutions to keep the weight down.
This includes an all new chassis, which mixes aluminum and carbon fiber. Ferrari has used new hollow castings and “quiet aluminum” to not only deal with the four-wheel drive and hybrid systems, but also keep vibrations and weight down. According to its figures, the SF90 Stradale chassis has a 40% higher torsional rigidity than predecessor platforms.
Ferrari quotes a dry weight for the SF90 Stradale of 3,460lb, although this is likely to rise to near 3,750lb with fluids and driver. That still equates to nearly 590hp/ton and that translates to some pretty sharp performance figures. 60mph comes up in a mere 2.3s, and it’s doing twice that just over four seconds later. Top speed is 211mph, and Ferrari says braking from 60mph to rest happens in just six car lengths.
There’s some serious work on the car’s aerodynamics too. The nose bears a similar appearance to the S-Duct on the 488 Pista and F8 Tributo, but Ferrari says it’s honed the system even further. More interesting is the treatment at the rear, where the SF90 Stradala employs a “shut-off Gurney”.
This system keeps the rear-end flush at normal driving speeds, but retracts into the car for high downforce situations — direction changes and heavy braking. That has the effect of exposing the fixed rear section to airflow and creating downforce.
Even the car’s wheels involve wings. Ferrari has designed the wheels in such a way as to act like rotors, pulling air from inboard through the wheel and out to create a smooth airflow down the sides.
The SF90 Stradale’s cabin includes a new instrument display and a new head-up display. The former is a curved, 16-inch, fully digital HD display, the first of its kind in a production car. It incorporates a rev counter dead center, with a battery indicator alongside, and audio and navigation information either side — although the drive can customize this display.
You’ll find the usual Ferrari-style array of switches on the steering wheel, including headlights, windscreen wipers and the “Manettino” drive mode selector. There’s also touch controls with haptic feedback that allow the driver to deal with almost all vehicle functions and information.
Ferrari is yet to reveal prices for the SF90 Stradale, but it’s rumored to be somewhere between the current flagship 812 Superfast and the holy trinity member La Ferrari. That puts it at around the $600,000 mark, with the first customers — 2,000 of which were at the unveiling — getting their keys at the start of 2020.
