Porsche has divulged power and performance details for its upcoming hybrid supercar, the 918 Spyder, ahead of the car’s launch next year.
In a bid to usurp car spy photographers, Porsche has released images of the first batch of production-oriented 918 prototypes finished in a black and white livery resembling that of the 917 racecars of old.
While it’s reassuring to see that the preliminary styling remains faithful to that of the sleek, low-slung concept, it’s the latest crop of powerplant details that will really bring a smile to the faces of hardcore Porsche enthusiasts and will, no doubt, assuage their concerns about the company’s halo model be powered by a plu-in hybrid set-up.
A 4,6-litre petrol V8 developing 419 kW augmented by an 80 kW electric motor on the front axle and a similar 90 kW item on the rear axle propels the prototype. The result is a staggering combined output of 566 kW – enough, Porsche claims, to rocket the 918 Spyder from standstill to 100 km/h in under 3 seconds and on to a top speed in excess of 325 km/h. Despite such thunderous performance, Porsche also claims that this powerplant will can also return an average fuel consumption figure of 3,0L/100km and CO2 emissions of just 70 g/km, thanks in part to its ability to run solely on electrical drive for more than 25 km at speeds of up to 150 km/h.
Porsche will commence production of the 918 Spyder in September 2013 with a view to getting the first examples to customers by the end of that year.
