Ferrari SF90 Spider produces 986 hp and can top-up in 14 seconds

the Ferrari SF90 Stradale is a plug-in hybrid supercar that Ferrari said needed a roadster version as well. This would be the car that Ferrari unveiled today: the SF90 Spider, for when you want 986 horsepower but also when you have wind in your hair and also want to spend over half a million dollars.

The powertrain of the SF90 is identical to that of the Stradale, with a 769 horsepower V8 and three electric motors filling the rest, for a total power of 986 HP. The Spider will run up to 62 mph in 2.5 seconds, says Ferrari; the top speed is 211 mph. Power goes through an eight-dual clutch speed.

The SF90 has electric, hybrid and all-wheel drive modes, depending on your persuasion. In electric mode, Ferrari said, the SF90 Spider has a range of 25 km and the internal combustion engine remains off, “which is ideal for downtown driving or any other situation in which the driver wishes to eliminate the sound of the Ferrari V8. “

Perhaps the most interesting differences between the SF90 Stradale and the SF90 Spider are the way Ferrari has handled the modified aerodynamics.

From Ferrari:

Key features of the SF90 Spider’s aerodynamic design include rear stop Gurney, an active control system that varies downforce on the rear axle, the front underbody with vortex generator strakes and forged wheels with wing profiles (blown geometry). The results in terms of performance are indeed impressive: massive downforce of 390 kg generated when cornering at 250 km / h with the Assetto Fiorano special specification.

In order for SF90 Spider operators to benefit from the massive 1000 hp they have at their disposal, efficiently and without compromise, without any negative impact on aerodynamic drag and downforce coefficients, it was essential to focus on efficient flow management. hot air from engine, gearbox, turbochargers. , battery, electric motors, inverter, charging system and, of course, brakes.

The engine compartment, for example, houses both the usual internal combustion engine which generates temperatures of almost 900 ° C and highly temperature sensitive electronic components. The RHT compartment radically modifies the management of thermal flows in the engine compartment: it is therefore essential that the hot air channeled upwards is correctly evacuated, and that the path it takes does not interfere with temperature sensitive electronic components.

Since the RHT compartment would have hampered the operation of the vents immediately behind the roof of the SF90 Stradale, transverse louvers were inserted into the rear window of the SF90 Spider. These have been sized very precisely to act as an efficient “chimney” without interfering with the aerodynamics of the car at high speeds.

Specific to the SF90 Spider, two aerodynamic elements in the cockpit guarantee an excellent level of protection against air flow with the roof down. There is a center section of trim between the driver and passenger seats that channels airflow away from the head and shoulders and in a double layer of trim on the top of the tunnel. These two solutions are essentially neutral in terms of drag and guarantee the same level of comfort as other Ferrari mid-rear motor spiders.

And here’s a little more on the retractable roof, which has been around in one form or another since 2011.

The Retractable Hard Top (RHT) has been adopted again as it provides optimum sound insulation and protection from the elements when raised, does not warp at high speeds and provides exceptional space and comfort for occupants. The RHT is so compact, simple and light that it can be operated in just 14 seconds and can be deployed while the car is in motion. The key to the success of the Ferrari RHT, which premiered on the 458 Spider in 2011, and which has continued to evolve over the intervening years, is that it only takes up 100 liters of space rather than the 150-200 liters required by a traditional system. The use of aluminum in its construction also means that it is around 40kg lighter than a conventional retractable hardtop. An adjustable electric rear window ensures excellent occupant comfort even at high speeds when the RHT is lowered.

Just like with the SF90 Stradale, the SF90 Spider is a very busy supercar. At least when you’re stuck in traffic in Monte Carlo, you’ll be able to feel the breeze.
