This Ferrari SF 90 Stradell There is a plug-in hybrid supercar that Ferrari also felt needed a roadster version. The same would be the car unveiled by Ferrari today: the SF90 Spider, when you want 986 horsepower, but wind up in your hair and let also want to spend-million dollars.
Powertrain of The SF90 is similar to the Straddle, with 769 horsepower making up the V8 And to fill the remaining three electric motors Total output of 986 hp. Ferrari says the Spider will run up to 62 miles per hour in 2.5 seconds. The top speed is 211 miles. Power passes through eightSpeed dual-clutch.
The SF90 has an electric, hybrid And all-wheel drive modes based on your persuasion. In electric mode, Ferrari SaysThe SF90 Spider has a distance of 15.5 miles and the internal combustion engine is off, which is ideal for a city-center. Driving or any other situation in which the driver wishes to remove the noise of a Ferrari V8. “
Perhaps the most interesting difference between the SF90 Straddle and the SF90 Spider is how Ferrari has dealt with altered aerodynamics.
From Ferrari:
Key features in the SF90 Spider’s aero design include a shut-gurf gurney at the rear, an active control system that converts to downforce on the rear axle, a front underbody with whirlpool generator strings and forged wheels with winged profiles (developed geometry). The results are really impressive in terms of performance: 250 km with the specification of special Aceto Fioro. Corning at a speed of / hour produces 390 kg of downforce.
To ensure that FF90 Spider drivers could enjoy the huge 1000 CV available to them, it was necessary to focus on effective management of hot air flow from engines, gearboxes, turbochargers, without any negative impact on aerodynamic drag and downforce coefficients. . , Battery packs, electric motors, inverters, charging systems and, of course, brakes.
Engine Bay, for example, has both common internal combustion engines that produce electronic components sensitive to temperatures of about 900 ° C, and temperature. The RHT compartment engine radically changes the management of heat flow in the bay: it is therefore essential that the hot air channeled upwards is properly evacuated, and that the path it takes does not interfere with temperature-sensitive electronic components.
Given that the RHT compartment may have interfered with the operation of the vents located behind the roof in the SF90 Straddle, transverse levers have been inserted into the rear screen of the SF90 Spider. These are very precise parameters for speed to act as an efficient ‘chimney’ without interfering with the aerodynamics of the car.

Special for the SF90 spider is the two aerodynamic elements in the cockpit, to ensure an excellent level of protection from the flow of air along the roof bottom. Between the driver and passenger seats is a central trim section that eliminates airflow from the head and shoulders and is in a double layer of trim at the top of the tunnel. Both of these solutions are essentially a neutral drag and guarantee the same level of comfort as Ferrari’s other mid-rear engine spiders.

And here’s a little more on the retractable roof, which has been in one form or another since 2011.
Retractable hard top (RHT) is re-adopted because it guarantees optimal sound insulation and protection of elements when raised, does not deform at high speeds and provides exceptional occupant space and comfort. The RHT is very compact, simple and lightweight it can take action in just 14 seconds and can be deployed when the car is running. The key to the success of the Ferrari RHT, which premiered on the 458 Spider in 2011, and which is constantly evolving in the intervening years, is that it takes up 100 liters of space instead of the 150-200 liters required by one. Traditional system. Aluminum is also used in its construction as it is 40 kg lighter than a conventional retractable hard top. Adjustable electric rear window guarantees superb business comfort even at high speeds when the RHT is lowered.
Like the SF90 Straddle, the SF90 Spider Is a very busy supercar. At least you can feel the wind when you get stuck in traffic in Monte Carlo.
