First Glimpse: Porsche 918 Spyder goes on track

While the production Porsche 918 Spyder is slated to be unveiled only at the 2013 Frankfurt Motor Show, the carmaker has recentlly let the guys at Wired take its prototype out for a spin on the track.

The 918 Spyder prototype uses a 4.6-litre V8 engine sourced from an ALMS LMP2 RS Spyder. It produces 570hp and is backed up by two electric motors.

One has a 121hp unit in the seven-speed transmission and the other with a 107 hp motor that powers the front axle. This setup gives the supercar hybrid a combined maximum output of 770hp and 749Nm of torque, and increasing to a whooping 948Nm with overboost.

Thanks to this impressive output, the prototype can run from 0-100km/h in less than 3 seconds and hit a top speed of 325km/h.
While these figures might change later in production phase the vehicle is slated to use a carbon fibre and aluminum chassis that weighs just 220kg. This will help the model to achieve an overall curb weight of approximately 1,678 kg.
