A look at European cars: the VW Beetle, the Trabant, the Wartburg 353, the Fiat 500, the Fiat 124 and the Lada which was based on the Fiat 124.

A look at two extremes: the massive American gas-guzzling "automotive palaces" with their excess of chrome and fins, and the low-powered three-wheeler microcars which could be driven without a driving licence or on a motorbike licence.

James continues to take a look at the examination of the social significance of cars by taking a look at how aspiration and new wealth were behind the development of some of the greatest cars ever built.

James reveals the cars that turned post-war Germany and Japan into motoring powerhouses at the expense of Britain and the US. On his travels he encounters classic E-Types, Mustangs and the German and Japanese upstarts that were to conquer the world. He also has an unfortunate encounter with an Austin Allegro - the car that helped destroy the British car industry.

James May goes off-road to tell the story of how the 4x4 conquered the world. From the wartime jeep to the global struggle between Land Rover and Land Cruiser, the white-knuckle world of rallying and boy racers, plus James conquers Mount Fuji and races through the sun-scorched Mojave Desert to decide which is the ultimate people's 4x4.

James explores the wilder shores of motoring to discover what happened to the cars of the future that we were promised. From improbable steam cars and ludicrous jet turbines, he reveals how the petrol engine and the power it gave us came to dominate the 20th century. He takes to the waves in an amphibious car, risks his life at the wheel of a notorious electric scooter and takes a hair-raising trip in the fastest driver-less car on earth.
