Porsche 918 Spyder: the quickest, richest and greenest Porsche ever | Car Advice

It may look a little raw, but the prototype in these images will soon give life to the fastest, most fuel-efficient and most expensive Porsche in history: the Porsche 918 Spyder.

With official details filtering through ahead of its 2013 unveiling, the Porsche 918 Spyder plug-in hybrid supercar looks set to take efficient motoring to an almost inconceivable level.

The 918 Spyder draws its power from three sources: a mid-mounted 425kW-plus 4.6-litre V8 engine, a 90kW hybrid module on the rear axle and an 80kW electric motor on the front axle. Its combined output will be in excess of 574kW, with peak torque above 750Nm.
