In season 18 of the world's most extreme car show, Jeremy Clarkson, Richard Hammond and James May visit India as they attempt to promote British trade armed only with three old cars, a badly behaved lawnmower and a trouser press. They also drive supercars across Italy, make a movie car chase, re-invent the mobility scooter, get soaking wet in track day cars, go motor racing for less than the cost of playing golf, investigate the Chinese car industry, immerse themselves in the world of NASCAR, and drive a brand new Ferrari through a snow field. Plus, The Stig hits the test track in the Mercedes SLS Roadster, BMW M5, Maserati GranTurismo MC Stradale, and an insane pre-war Bentley powered by a 27-litre Spitfire engine, and the Reasonably Priced Car feels the raw driving power of stars including will.i.am, Ryan Reynolds, Slash, Matt LeBlanc, Michael Fassbender and Matt Smith.
