They also tested the Vauxhall (Holden) VXR LS2-engined and compared it to BMW M5 and the VXR. Clarkson loved it. The Stig didn't get a good time but the track was wet.
This is the same platform as the new Camaro is built on.
Another cool thing, I am watching the show at the moment, was the Hamster driving the Renault F1 car. he did really well. When that episode ended the Renault engineers had programmed the engine to play God Save The Queen by revving the engine. LOL
