The 20th series of the world’s most popular car show sees Jeremy Clarkson, Richard Hammond and James May on typically explosive form. In the course of six packed programmes, they set out to race a car against an America’s Cup yacht up the coast of New Zealand, launch a highly scientific process to find the world’s fastest taxi, and blast across recession-hit Spain in three ‘affordable’ supercars. There are also track tests of the Ford Fiesta ST, Peugeot 208 GTI, Renaultsport Clio 200 and Mercedes SLS Black, and the show welcomes a brand new Reasonably Priced Car in which celebrity guests will perform their fast laps.
