In "Supercar Showdown", Jeremy Clarkson travels the planet - from Spain via Strasbourg to Swindon, England - for the Supercar Showdown to beat them all. The aim is simple - find the ultimate Supercar. He starts a fight between a prancing horse and a raging bull as topless versions of the Ferrari 430 and Lamborghini Gallardo slug it out. The Glassardo's big cousin, the Murcielago, weighs in too. The Ferrari 599 GTB Fiorano struts its stuff and Audi's R8 faces up to the Porsche GT3 as his special guest, Nurburgring-know-all Sabine Schmitz, takes on The Stig. Jeremy turns into a Formula 1 hero thanks to a Radical SR3, and he has a fantastic time in the Aston Martin Vantage V6 Roadster. Plus there's a new kid on the block in the shape of the stunning Ascari A10. And the line-up would not be complete without the 1000 horsepower, 252 miles per hour Bugatti Veyron. So he blasts off in one of those too. Meanwhile, everything else explodes as he find out if there is such thing as "too much" turbo power, a Renault Alpine A610 comes to the end of the road and he answers the big question - which is stronger, the electric G-Wiz or a table?.
