Thriller

S2, E3: Thriller, as the name suggests, is all about thrills at the wheel. Aston Martin's gentleman thug, the DBS, takes on its rivals from Italy. The lightweight Lamborghini Superleggera battles it out on the track with Ferrari's 430 Scuderia and Clarkson's test of the best takes him to the breathtaking roads of the Swiss Alps, the no limits German autobahn - and, er, Norfolk.
