Jeremy Clarkson travelled the planet to find the ultimate Supercar. He compares the topless versions of the Ferrari 430 and Lamborghini Gallardo. The Gallardo'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 special guest, Sabine Schmitz, takes on The Stig. Clarkson also has go at being a Formula 1 hero thanks to a Radical SR3 and has a fantastic time in the Aston Martin Vantage V8 Roadster. Plus there's a new kid on the block in the shape of the stunning Ascari A10. Finally, the line-up would not be complete without the 1000 horsepower, 252 mph Bugatti Veyron.
