Ferrari SF90 Spider
In the center of the hurricane
The idea is simple. You take the Ferrari SF90 Stradale, flex the roof and you have a puristic hyper-roadster. Said and done.
If you want to use voice control with the Ferrari SF90 Spider at all times, you should be in good voice. At the top speed of 340 km / h, such a hurricane is probably blowing through the cockpit that the code word “Ciao Ferrari” has to be shouted with all your strength to activate this function. Nevertheless: Anyone who finds the muse at this speed either has the talent of a Formula 1 driver or is completely free of pain.
The mutation to become an outdoor athlete happens pretty quickly. The roof disappears behind the driver within 14 seconds and up to a speed of 45 km / h. For once, the Italians forego the big staging and simply let the hardtop do a somersault. This compact design of the headgear does not impair the chic silhouette of the beautiful two-seater. “The retractable hardtop is the best solution for weight management and comfort. In addition, the influence on aerodynamics is only very limited”; explains chief technician Michael Leiters. That means: As with the SF90 Stradale, a contact pressure of 390 kg is generated at 250 km / h.
As soon as the hat is gone, the elements have free access to the cockpit. Be it the aforementioned hurricane or the sound of the eight-cylinder biturbo roaring powerfully from four liters of displacement. “At low speeds the sound is bass-heavy, at higher speeds it is more of an exciting metallic soprano.”; says Michael Leiters. Since the maximum torque of 800 Newton meters is only available at 6,000 rpm and thus only 2,000 rpm below the maximum speed, this pitch will be the preferred one. The drive train corresponds to that of the Ferrari Stradale SF90. But you can’t let this 730 KW / 1,000 PS work of art melt in your mouth enough. The focus is on the 574 kW / 780 PS petrol engine. Anything else would be considered blasphemy in Maranello. After all, Enzo Ferrari described the engine as the soul of a Ferrari. There are also three electric motors with a total output of 156 kW / 220 PS.
The division of drive tasks is subordinate to agility and dynamics. While the combustion engine is responsible for the rear axle, two electric motors on the front axle ensure maximum recuperation and traction on command. With this “on demand” all-wheel drive, the two electric motors can be controlled in a targeted manner. That helps with turning in. “This makes the car feel 200 kilograms lighter”; says Michael Leiters, which is not entirely insignificant given a vehicle weight of 1,670 kilograms. The third electric disc is located between the eight-speed dual clutch transmission and the combustion engine. If all-wheel drive is active, the torque distribution between the front and rear axles is fully variable.
In this Ferrari, too, the steering wheel is the central control element. The valance is accordingly lavishly equipped. With the E-Manettino you can choose between four driving modes: “eDrive”, “Hybrid”, “Performance” and “Qualify”. With “eDrive” and the energy from the 7.9 kilowatt-hour battery, you can travel a maximum of 25 kilometers on electricity. The ultra-fast Ferrari has a bit of a VW Golf, then with this driving program only the two electric motors on the front axle are active and accelerate the Italo flounder to a maximum of 135 km / h. With “hybrid” the system swings the baton and pays attention to efficiency.
“Performance” is something for highway hunters. The electric motors are at hand to support the propulsion at lightning speed or to provide dynamism and traction. But a Ferrari wouldn’t be a Ferrari if you couldn’t unleash a drive storm. Whoever drives to victory gets everything out of the car with “Qualify”, which is only enough for a few laps on the race track. In terms of longitudinal dynamics, the Ferrari SF90 Spider is hardly inferior to its Stradale brother: It takes an identical 2.5 seconds from zero to 100 km / h, 200 km / h is reached after seven seconds (plus 0.3 seconds) and there is top speed tied again at 340 km / h.
