Hear the pre-production prototype of the upcoming 2013 Porsche 918 Spyder in ACTION!

That’s the sound of a plug-in hybrid driveline that mixes a 570PS (+562hp) 4.6-liter V8 petrol linked to a 7-speed dual clutch transmission with two electric motors for a combined output in excess of 770PS (+762hp)… Not bad for a hybrid.
