Part 1 of 2. Jeremy, Richard and James are challenged to drive from Colditz to the German border using just 13.5 litres of petrol, each using very different cars - a Ford, a Merc, and a BMW. Can they pull it off? Great outtake from Series 15 of Top Gear.

Part 2 of 2. With the score at 2-1 to the Grosser, Jeremy Clarkson and James May take their cars to London for what seems like the easiest test ever. But trying to park a huge car in a tiny space isn't as simple as it seems! Brilliant challenge video in high quality from BBC motoring show Top Gear.
