In the all-new 21st series of the world's favourite car show, Jeremy Clarkson, Richard Hammond and James May embark on a huge and potentially glowing road trip across Ukraine in three small cars with even smaller engines, re-live the glory days of the 1980s in three 'classic' hot hatchbacks, and have a ham-fisted crack at making a public safety film for the government. There’s also the new Alfa 4C sports car racing a very unusual quad bike, the sensational McLaren P1 tearing a strip off Belgium, an insane six-wheeled Mercedes in the desert, and the unusual sight of James May in a Caterham. And as if that wasn’t enough, the series includes an epic two-part adventure across the wilds of Burma as the presenters take three lorries on what could be Top Gear's toughest challenge to date.
