Martini is back, and the livery has lost none of its power to impress. The colour scheme has been seen on prototypes of the Porsche 918 and also this GT3 Cup racer. A car, incidentally, which has been raced this season by one Sebastian Loeb. It's based on the GT3 RS road car and uses the same 3.8-litre flat six, but actually develops slightly less power due to the compulsory air restrictor.
