The SF90 Stradale represents many firsts for Ferrari. It’s the legendary automaker’s first plug-in hybrid electric model, the marque’s first all-wheel-drive supercar, and the most powerful Ferrari production car ever sold. The SF90 boasts the highest output ever for a Ferrari V-8 and, in fact, this is the first time a V-8 has powered a top-of-the-range Ferrari model. Not a replacement for LaFerrari, the SF90 Stradale’s name celebrates the 90th anniversary of the founding of the Scuderia Ferrari racing team that harkens back to 1929.
The two-seat SF90 Stradale supercar combines the output of a rear-mounted, 4.0-liter twin-turbocharged V-8 engine and three electric motors. A motor/generator between the engine and the transmission drives the rear wheels. Two motors at the front axle, which are not mechanically connected to the internal combustion driveline, drive each front wheel. This results in a sophisticated AWD system that Ferrari says is needed to handle the SF90 Stradale’s tremendous horsepower.
The SF90 V-8 makes 769 horsepower at 7,500 rpm, while the three electric motors add 217 horsepower to bring a combined 986 horsepower and 590 lb-ft torque to this supercar. Since the electric motors provide instant torque from 0 rpm, Ferrari claims a 0-62 mph (0-100 km/hr) time of 2.5 seconds, with the car hitting 124 mph (200 km/hr) in 6.7 seconds. Top speed is 211 mph (340 km/hr).
Interestingly, the 8-speed automatic transmission has no reverse gear since the front motors handle backing up. The hybrid system also helps further improve Ferrari’s renowned braking. The SF90 Stradale’s brake-by-wire system allows braking torque to be split between the hydraulic system and the electric motors’ regenerative braking, boosting both performance and brake feel.
There are four drivetrain modes – eDrive, Hybrid, Performance, and Qualify. In eDrive, the Stradale is powered solely by the two front motors, making it a front-wheel-drive EV. A 7.9 kWh lithium-ion battery provides an all-electric range of about 16 miles with a top speed of 84 mph, depending on road conditions and how quickly the car accelerates. Hybrid is the default mode when the car starts up. Here, all three electric motors and the gasoline engine work together to achieve optimum fuel efficiency and performance. In Performance mode, the V-8 is always providing power for great performance.
In Qualify mode, the V-8 and all three electric motors provide their peak output with no regard for fuel economy.
The new SF90 Stradale is relatively light even with its batteries and three motors. Curb weight is 3,527 pounds, a nod to lightweighting and other measures. For example, hollow castings replace conventional ribbed castings. Two new aluminum alloys are used including a high-strength 7000 series alloy for some of the body panels. Carbon fiber is used for the bulkhead separating the engine from the interior. The SF90 Stradale’s chassis features 20 percent increased bending stiffness and 40 percent higher torsional rigidity than previous platforms, without any increase in weight.
Adding to this Ferrari’s exceptional driving experience, the steering wheel allows controlling virtually every aspect of the SF90 Stradale without ever taking hands off the wheel.
