The Top Gear boys - Jezzer, Hamster and Captain Slow - can do brake-horsepowers, torques and 0-60s until the pumps run dry. But when they take on a challenge, the action gets competitive, hilarious, dangerous and, at times, downright humiliating.

Robin Reliant Space Shuttle:

Combining cutting edge amateur rocketry, British Grit, and truly intergalactic levels of messing about, Richard and James try to put a Reliant Robin into space.

Building Amphibious Cars:

Can the lads create a vehicle equally at home on land and water? Will they even make it across the reservoir without drowning or catching hypothermia?

Building a Limo:

The boys are up against it, making their own stretch limos from everyday cars. But the challenge has only just begun. There are some high-profile celebs who need a lift to the Brit Awards…

Building a Convertible:

Attempting to turn a Renault Espace into a fashionable 'drop top', the team prove that trying to make your own convertible is a bit like trying to cut your own hair… you can do it, but you probably shouldn't…

Parkour vs Peugeot 207:

They may wear silly trousers but these parkour (the barmy sport of leaping across rooftops across the city) lads are serious competition for Captain Slow's Peugeot 207 in a race through Liverpool.

Veyron Race from Alba:

It's Top Gear's most dramatic race yet. Jeremy's in the Bugatti Veyron - the fastest, most lavish supercar ever - while Richard and James are in a flying washing machine - with Captain Slow at the controls!

Crap 70s Supercars:

They were once state-of-the-art Italian supercars - the Maserati Merak, the Ferrari Dino 308GT4 and the Lamborghini Uracco. Now, all the lads need to do is try to drive them from Bristol to a "gentleman's" club in Slough.
