Porsche's answer to the McLaren P1 and LaFerrari. Only it's more of a challenge to them, because the Porsche arrived first and wasted no time posting a 6.57mins Nürburgring lap time. Underneath is a carbon tub into which Porsche has packed a new 4.6-litre 608bhp naturally aspirated V8 and a pair of electric motors (one per axle - the 918 is 4WD) that produce a combined 282bhp.
