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.
