Duel - it's all about challenges and some big questions. Which car makes the most smoke while going sideways - a Lamborghini Murcielago Super Veloce 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, Jeremy 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 Jeremy corner in flippers? Can Formula One ace Anthony Davidson slide a car - in ice skates? Which is faster - a car or a man? Find out as the Aston Martin v12 Vantage sprints against flying rugby winger Tom Varndell in a 100 meter drag race. And at last, the Stig goes head to helmet against the Tiff. The white-suited racing driver and Jeremy join forces against Vicki Butler-Henderson and Tiff Needell. There's carnage in an auto-test and the 190mph Aston Martin DBS Volante is pushed to the limit against Vicki in a £150,000 Ferrari California. A Ford Focus RS is also picked up for a road race against his Stigness in a Lamborghini Gallardo Spyder, and much, much more.
