Engine and performance
The most significant number for the SF90 Stradale is 1000. That's the total horsepower figure (986bhp) that the petrol-electric powertrain makes: 36bhp more than the LaFerrari's and the most of any roadgoing Ferrari ever built.
The heart of the car is Ferrari’s award-winning ‘F154’ twin-turbocharged V8, bored out from the 3902cc of the 488 Pista to 3990cc. Engineers claim a complete redesign, including new combustion, intake and exhaust systems, while a narrow cylinder head, with a Ferrari V8 first in a new 350-bar direct injection system, features.
The resulting output of the engine alone is 769bhp, with 590lb ft of torque at 6000rpm. The new engine design, in which the turbocharger is mounted lower and the flywheel is smaller, results in a lower centre of gravity. The exhaust system also makes use of the super-alloy Inconel instead of steel to save weight, while Ferrari claims a “fuller, richer” sound.
Complementing the V8 is a trio of electric motors - two mounted at the front and one mounted at the rear between the engine and gearbox, giving all-wheel drive. All three generate a total of 217bhp to make the 986bhp total. They are powered by a relatively small (7.9kWh) lithium ion battery pack that makes the SF90 Stradale capable of 16 miles of electric-only running at speeds of up to 84mph. The battery can be charged either by plugging it in (no charging time has been revealed) or using the engine as a generator.
The two power systems channel through a newly developed eight-speed dual-clutch automatic gearbox. It’s lighter and more compact than the outgoing seven-speed unit and promises an 8% reduction in fuel consumption in normal driving on the WLTP cycle. Shifts are also claimed to be 30% faster. The advancements also extend to the brakes, with Ferrari recording a 100-0mph stopping distance 2m shorter than the LaFerrari.
All of this results a 0-62mph time of 2.5sec - a record for a roadgoing Ferrari. Furthermore, 0-124mph takes 6.7sec, while the top speed (claimed not to be the main performance focus) is 212mph. Ferrari also says the new car pulls out a 64-metre lead from the LaFerrari in one lap around its Fiorano test track.
A new power mode selector, dubbed eManettino, can be cycled through four driving modes. eDrive keeps the engine switched off for as long as the battery lasts, while Hybrid is the default setting, balancing both power sources; Performance keeps the engine running to ensure the battery is fully charged and Qualify allows maximum electric motor power for a certain time period to deliver all-out performance.
