Jeremy Clarkson, Richard Hammond, James May and the Stig return.

Jeremy asks why there aren't more three-wheeled cars in the world and investigates further with a closer look at the 1980s comedians' favourite, the Reliant Robin.

Meanwhile, James gives Top Gear's favourite warhorse, the Toyota Hilux pick up, one final assignment as he attempts to drive one up an active volcano in Iceland and the Stig rips up the track in the new Bentley Continental Supersports.

Plus, Richard gives the old Chevrolet Lacetti a dignified send-off before he and Clarkson host a star-studded tea party to welcome in a shiny new Reasonably Priced Car.
