In the last episode of the series, Jeremy James and Richard take three cars to Spain: the new BMW M3, Mercedes C63 AMG and the Audi RS4. James drives the new Jaguar XF and Richard turns a G-Wiz into a radio-controlled car.

Jeremy, James and Richard take part in Britcar 24, a 24-endurance race at Silverstone. James travels to Budapest to race the new Fiat 500 against boys on BMXs and Stig takes the Ascari A10 around the Top Gear track for a Power Lap.

Richard drives Renault's 2006 F1 car around the Stowe circuit at Silverstone. The Vauxhall VXR8 is tested on the track and there's a BMW which can drive itself.

To celebrate 40 years of British Leyland, Jeremy, James and Richard find three cars made by B.L. that weren't that bad after all. Surely that is one of the most ambitious tasks ever undertaken by the boys.

Jeremy finally shows concern for the environment by suggesting a replacement for 4x4s. Well, sort of… he compares the 507bhp AMG Mercedes E Class estate, with the BMW M5 Touring, which only has 500 bhp. Richard and James try their hands at a new motor sport – Motorhome Racing. In the studio, Jeremy has a £750,000 motor home called the Performance.

Jeremy, James and Richard race each other using a bike, a boat and a car to find the fastest way across London. The Stig drives the 'potato baking' Caparo T1 on the track in an attempt to beat the long-standing fastest time set by the Koenigsegg.

African Special: The boys travel to Africa with a mission (or two): they must each buy a car – but not a 4x4 – for no more than £1,500. They must then drive the cars they buy across fairly unforgiving terrain in Botswana - including the Makgadikgadi salt pans, raging rivers and game reserves. Game reserves… that’s where big carnivorous animals live, isn’t it? Hmm...

Have you ever wondered which would win in a race between a Typhoon jet fighter and a Bugatti Veyron driven by Richard? Neither have I, but it should be a giggle. As should the self-parking Lexus LS600h - a demonstration of which could well end in more headlines. The new Lamborghini Reventón - the new limited-edition model based on the Murciélago LP640 - will also be in the studio.

More amphibious fun with the TG3, as they attempt to cross the Channel to France in their amphibious vehicles from series 8 (episode 3). Richard has a new redesigned 'Dampervan' and Jeremy's 'Toybota' is replaced by a 'Nissank'.

To celebrate 30 years of the Golf GTI, Volkswagen have clearly cracked open several bottles and consumed the contents. How else could you explain the 640bhp Golf GTI W12?
