Top Gear - Season 5

The power of the new Porsche 911 Carrera S is put to the test on the track, Jeremy has to eat more than his words about the Vauxhall Astra and the Brits take on the Americans and Australians in a three car challenge.

Richard road-tests the new Ford Focus and Pink Floyd drummer Nick Mason lends Jeremy his new Ferrari F60, but he decides to also put some 15-20 year-old supercars through their paces.

We look at 4x4s to see which really can go off-road, but Jeremy takes it too literally and decides to drive a Land Rover Discovery up a Scottish mountain. Also, the Dodge Viper SRT-10 slithers around the Top Gear test track.

Richard heads for the south of France, via the Alps, in the Pagani Zonda roadster, Top Gear gets its hands on steel cable and cranes for a fun filled game of caravan conkers and there's a clash of titans on the test track.

Richard drives the Morgan Aero 8 GTN, and invents a new sport: racing people carriers. James celebrates 50 years of the Mercedes SL Gullwing. Jeremy tests the diesel engine in the Jaguar S-Type by driving it as fast as he can around Germany's notorious Nürburgring.

Can you buy a decent Porsche for under £1,500? The presenters are each sent out to buy one, but which will perform best in our tests? Also in the show, Jeremy tests the VW Golf GTI and we find out how fast a blind man can drive round the Top Gear track.

Jeremy discovers the Toyota Prius is like a lethargic teenager, Richard takes a Mustang on a road movie across Lincolnshire and a four-door saloon (the Evo) goes head to head with a Lamborghini.

Who can reach the ski slopes of Verbier in Switzerland first: Jeremy by road in a Ferrari 612 Scaglietti, or Richard and James in a plane? In Lillehammer, there's another contest: who can get down a mountain fastest - James in a Mitsubishi rally car, or Richard in a bobsleigh?

James drives the controversial new BMW 1 Series hatchback. Richard splashes about in a 25-year-old supercharged Mercedes G-Wagen. The Fiesta ST is pitted against the Citroen C2, and Jeremy has his face pulled off while driving the Ariel Atom.
