Ferrari SF90 XX Stradale and SF90 XX Spider, two track cars homologated for the road

Whenever Ferrari presents a new model, everyone pays attention. If it is also a version carrying the XX designation, we pay even closer attention. Behind these two letters lie the most radical versions of the brand, built to give everything on the track. But in this case there is something more: although they deliver more than 1,000 CV, these two models are homologated to be driven on public roads and city streets.

The Ferrari SF90 XX Stradale and the SF90 XX Spider are ready to go on sale and offer all the radicalness of this hybrid model of Ferrari, but aimed at both the track and the road. In addition, they will be produced in limited numbers. The SF90 XX Stradale will have 799 units, and the convertible version will have only 599 units.

Domesticated radical cars

The Ferrari cars that have received the XX designation have been track-only cars. This allowed them to shed the technical requirements needed to drive on the road. The amount of emissions, the size or the aerodynamic elements did not matter. They were built to deliver the best performance on the track, so nothing else was a concern.

But these two variants break with that trend and will let the few drivers who can get close to them enjoy their characteristics in everyday use.

Powertrain

Both models are equipped with a 4.0-litre twin-turbo V8 engine, mounted in the mid-rear position. This unit delivers 797 CV, surpassing the 780 CV of the version they are based on. Its peak torque is 804 Nm at 6,250 rpm, and several of its features have been improved, such as the intake, the exhaust and the pistons.

Alongside this engine there are three electric motors. The first sits between the engine and the gearbox, so it adds thrust to the rear axle. The other two send their torque to the front wheels, giving all-wheel drive. Overall, the hybrid system delivers 1,030 CV.

The battery that powers these motors has a capacity of 7.9 kWh, which gives it a range of 25 kilometres at a speed of 135 km/h. This means it will receive the ECO label from the DGT in Spain.

A fixed rear wing

One of the novelties of this model is the fixed wing mounted at the rear. Normally, Ferrari uses active wings on its road-going models. For these two models, a fixed one has been chosen, which will give better aerodynamic behaviour off the track.

Another detail found on the convertible version is the roof. In this case, it is powered and can be raised and lowered at speeds of up to 45 km/h in just 14 seconds. The weight of the coupé is 1,560 kg, while the Spider weighs 1,560 kg. No price has been announced yet, but it is expected to be revealed soon for the units destined for Spain.
