Ferrari SF90 Stradale trailblazes the plug-in hybrid path for Ferrari and hopefully leads to all-electric future
Ferrari isn’t yet ready for all-electric cars, but there is no escape from the future and after its first tries with hybrids, the Italian manufacturer recently unveiled its first plug-in hybrid Ferrari SF90 Stradale.
The all-electric range of up to 25 km (15.5 miles) on a tiny 7.9 kWh battery is not a breakthrough. However, having two electric motors in the front (in addition to the usual gas engine in the rear) enabled Ferrari to build its first model with all-wheel drive.
The performance gains could not be scorned because the Ferrari SF90 Stradale can do 0-100 km/h (62 mph) in 2.5 seconds (200 km/h in 6.7 seconds) and reaches a maximum of 340 km/h (211 mph).
“The SF90 Stradale is equipped with three electric motors capable of generating a total of 220 cv (162 kW). A high performance Li-ion battery provides power to all three motors and guarantees a 25-kilometre range in all-electric eDrive mode, using just the front axle. When the internal combustion engine is turned off, the two independent front motors deliver a maximum speed of 135 km/h with longitudinal acceleration of ≤0.4 g. Reverse can only be used in eDrive mode which means the car can be manoeuvred at low speeds without using the V8. The front motors are integrated into the launch control strategy for maximum performance when accelerating.”
“Ferrari’s engineers were able to further broaden the spectrum of dynamic controls by introducing the full-electric front axle, known as the RAC-e (electronic cornering set-up regulator). As well as exclusively providing propulsion in electric drive, the two front motors independently control the torque delivered to the two wheels, extending the concept of Torque Vectoring. Fully integrated into the car’s vehicle dynamics controls, the RAC-e governs the distribution of torque, making driving on the limit much simpler and easier.
The introduction of this hybrid architecture was a challenge with regard to managing the additional weight which was resolved by an obsessive attention to detail and the overall optimisation of the whole of the car. For maximum performance in terms of overall weight, rigidity and centre of gravity, the chassis and bodyshell of the SF90 Stradale is all new, built using multi-material technology, including, for example, carbon fibre.”
Hopefully, once Ferrari tastes electrification, there will be no going back.
