Porsche 918 Spyder Martini Racing unveiled [Photo Gallery] image

Porsche has unveiled first images with the 918 Spyder Prototype which is currently undergoing development testing.

It’s a hat tip to the old histroic racers that wore the team livery during the late 60′s and early 1970′s.

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

The systems’ combined power output is expected to be greater than 770 hp, and the NEDC fuel consumption is forecast to be only around three litres per 100 km, equivalent to CO2 emissions of about 70 g/km.

The first is a 4.6 liter V8 originally fitted to the three-time ALMS LMP2 Championship-winning RS Spyder. This will feature 570hp on its own and the exhaust outlets will exit in the middle of the engine block to reduce engine compartment heat.

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.
