VIDEO: Porsche 918 Spyder on the Nurburgring

Road & Track look at the Porsche 918 Spyder, testing on the Nordschleife. The mid-mounted 4.6 litre V8 produces 580bhp – which is more than the RS Spyder LMP2 race car it's based on – and the lithium-ion battery feeds 200 kW of power to the electric motor driving the front wheels. All of this resulted in a 7m14s lap... which is good, but in the light of the 2013 Nissan GT-R time of 7:18.6, is it quick enough?
