The Grand Tour - Season 4

The route begins in Cambodia at Siem Reap and then winds downriver to Tonlé Sap lake, before joining the Mekong Delta and sailing into Vietnam. The final port of call is Vung Tau, in south Vietnam.

The intrepid trio find themselves back on four wheels for their latest adventure. Armed with sports cars, Richard, James and Jeremy think they are in for a cushy road trip as they arrive on the exotic island of Reunion and race on the world's most expensive piece of tarmac. But a bizarre challenge propels them to Madagascar where they must tackle the world's toughest road.

Confined to the UK by Covid, Jeremy, Richard and James embark on a Lockdown Special to find out just why American 70s cars never took off in Britain. At the wheel of a Cadillac Coupe De Ville, a Lincoln Continental and a Buick Riviera in stunning Scottish surroundings, the three hosts undergo many mishaps and adventures before embarking on one of their toughest challenges yet.

In this second Lockdown Special, the trio dive into the bizarre world of French car culture. On an epic road trip starting in the Welsh hills, they dish up a hair raising mountain climb, bomb defusals, propellor powered cars, helicopter stunts and the most thrilling race of their lives before reaching the English Channel for a jaw dropping medieval climax. And a soupcon of French art house cinema.
