Porsche 918 Spyder plug-in hybrid super car

31 July 2012

"Porsche 918 Spyder hybrid car"

 

The Porsche 918 Spyder plug-in hybrid super sports car has made an appearance in the Martini®Racing livery; made famous in the 1970s as the colour scheme of many successful Porsche race cars.

The 918 Spyder plug-in hybrid super sports car was aiming to lap the 20.8 km Nürburgring race circuit in under seven minutes 22 seconds.

The Porsche 918 Spyder combines a high-performance internal combustion engine with electric motors on the rear and front axles to achieve extraordinary driving performance and excellent efficiency.

The combined system power of the drivetrain is 770 hp and CO2 emissions forecast to be about 70 g/km. While the livery of the prototype is reminiscent of historical models, this advanced technology ensures the Porsche 918 Spyder is clearly a super sports car for the future.

 

The monocoque of the 918 Spyder is constructed from carbon fibre reinforced polymer (CFRP), which reduces vehicle weight and delivers remarkable rigidity and dynamic precision. Other highlights are fully variable aerodynamics, adaptive rear axle steering and the ‘top pipes’ exhaust system which routes the exhaust upwards at the rear of the car.
