Ferrari SF90 Spider: 100 kg heavier than the coupe, but with a rigid folding roof

27 Nov

Scuderia Ferrari has unveiled the first ever plug-in open-top hybrid supercar, the SF90 Spider. The technical stuffing is entirely borrowed from the sister coupe SF90 Stradale, but the design has more interesting features than it might seem at first glance.

The Ferrari SF90 Stradale coupe made its debut in the spring of last year, but due to the coronavirus crisis, deliveries to most countries have not yet begun. In fact, the coupe and spider will go on sale simultaneously in the coming months, while the prices for the coupe have long been known (in Europe – from 430 thousand euros), and the price tag for the Spider has not yet been announced.

Meanwhile, even with the expected mark-up, the Spider seems to be better than a coupe, if, of course, you want to have a recreational sports car, and not set records at the circuit. The dry weight of the SF90 Spider is 1670 kg versus 1570 kg for the SF90 Stradale – both figures include the optional Assetto Fiorano “lightweight” package. In the case of the Spider, it reduces weight by 21 kg and includes two-tone paintwork, increased use of carbon fiber in the body structure, titanium suspension elements, Multimatic racing shock absorbers and Michelin Pilot Sport Cup 2 tires, which are optimal for driving on dry asphalt.

The SF90 Spider is equipped with a folding and very compact rigid aluminum top – when folded it takes only 100 liters, and when unfolded allows you to operate the machine in any weather conditions and not be afraid of, for example, sharp icicles falling. The folding-unfolding process takes only 14 seconds and is fully automated. The rear window is also electrified and eliminates unwanted air turbulence in the cabin when driving with the top down. There is also a small trunk of 74 liters. Ferrari Portofino M: Old Design, New Electronics And Powertrain From Roma

The convertible top is expertly integrated into the active aerodynamic body and does not spoil its striking design. The developers report that in order to create a harmonious image, they had to slightly move the cab forward, increase the tilt of the windshield, lower the roof by 20 mm and reduce the thickness of the front pillars – a very large-scale alteration for converting a coupe to a convertible.

The plug-in hybrid powertrain is the same as the coupe. It consists of a 4.0-liter gasoline “biturbo-eight” (780 hp, 800 Nm), an 8-speed “automatic” type DCT (with two clutches) without reverse gear, a lithium-ion battery with a capacity of 7.9 kW ยท h and three electric motors: two rotate the front wheels and are responsible for the electric mode and reverse movement, and the third is implanted between the internal combustion engine and the gearbox. The maximum total power of the power plant is 1000 hp. On electric traction (and front-wheel drive, respectively), the Ferrari SF90 Spider can travel 25 km on a single charge, with a maximum speed of no more than 135 km / h. The certified carbon footprint has not yet been specified, for the SF90 Stradale coupe it is 154-160 g / km, depending on the version.

The first “hundred” Ferrari SF90 Spider gains in the same 2.5 seconds as the coupe, the maximum speed for both cars is also the same – 340 km / h. But the extra hundredweight affected the acceleration from standstill to 200 km / h: for the SF90 Spider it takes 7.0 s, for the SF90 Stradale – 6.7 s. God knows what a price to pay for the ability to fold the roof down at any time and enjoy the ride in the fresh air.
