S2, E4: It’s all about challenges and some big questions. Which car makes the most smoke while going sideways – a Lamborghini Murcielago SuperVeloce or a Vauxhall VXR8 Bathurst S? What is best at drifting? – the Jaguar XKR, the Lotus Evora, Audi’s R8 V10 or BMW’s M3? To find out, Clarkson globe-trots from sun-drenched Spain to Silverstone via Oxfordshire…and Swindon. There is serious science too. Can The Stig drift a car while wearing wellies? Can Clarkson corner in flippers? Can Formula One ace Anthony Davidson slide a car – in ice skates? Who is the best at off road driving? – Newswoman Kate Silverton, rugby’s Matt Dawson, singer Ronan Keating – or Clarkson? Which is fastest – a car or a man? Find out as the Aston Martin v12 Vantage sprints against rugby winger Tom Varndell in a 100 metre drag race. And Clarkson and The Stig join forces against Vicki Butler-Henderson and Tiff Needell. Meanwhile everything else explodes.
