Porsche 918 Spyder hits the Nurburgring (video)

The Porsche 918 Spyder – Porsche’s hybrid replacement for the Carrera GT – has been caught on video at the Nurburgring. Incredibly, it’s more that two years since Porsche took the wraps of the 918 Spyder at the 2010 Geneva Motor Show, yet we’re still more than a year away from actually seeing production cars. But Porsche are putting their time to good use. Porsche has made a few cosmetic tweaks already from the original 918 Concept, but they’ve also let it be known that the 918 Spyder will get a 550bhp 4.6 litre V8 to go with its electric motors on the front wheels  (one less motor than originally envisaged – there was going to be one one the back axle too), which will make the 918 Spyder a FWD Porsche when in EV mode.
