The SF90 XX Stradale has inherited the SF9O Stradale’s signature PHEV layout, in which the V8 internal combustion engine is integrated with three electric motors, two independent on the front axle and one located between the engine and gearbox at the rear. This configuration allows the car to unleash a maximum of 1030 cv (+30 cv more than the SF90 Stradale), setting a whole new Ferrari performance benchmark.
Thanks to its massive 797 cv, the mid-rear-mounted V8 turbo raises the performance limit bar still further for this particular architecture. The SF90 Stradale’s power unit has been developed to be more extreme, thanks to an increased average compression ratio, achieved through polishing the inlet and exhaust tracts as well as specific machining of the combustion chamber and pistons. The removal of the secondary air system also slashed 3.5 kg off the engine’s weight.
The redesign of the SF90 XX Stradale’s soundtrack also brings its racing soul to the fore: to produce an even fuller, richer sound and celebrate the harmonics right across the V8’s rev range, the hot tube system was optimised. This transmits the combustion pulsations into the cabin, highlighting the high-frequency treble to reveal the ultimate evolution of the Ferrari V8 at its most magnificent.
The 8-speed dual-clutch gearbox that made its first appearance on the SF90 Stradale, also reappears on the SF90 XX Stradale. However, the gear-shift logic hase changed significantly: the car uses the logic introduced on the Ferrari Daytona SP3 to enhance gear-shifting sound and the resulting driving thrills, by introducing a noise similar to the tell-tale pop from the exhaust that happens on lift-off at medium/high revs in high performance driving. To that end, a specific new engine calibration was developed that works in synergy with the gearbox control logic.
