The Grand Tour attempts to set a new British water speed record for amphibious cars. A staggering 85 percent of all people who try to break records on water are killed but this doesn't put off Clarkson, Hammond and May as they set about building their own road legal machine from an unholy union of car, boat and jet engine and then use it to spear across the choppy waters of a vast lake during something called "Coniston Speed Week". Also in this show, Jeremy makes a nostalgic trip to the Eboladrome to drive a pair of incredible supercars from the early 1990s, the Jaguar XJ220 and the Bugatti EB 110 Super Sport.
