The Paris-Dakar Rally is one of the last great motorsport adventures, travelling thousands of miles through the most challenging terrain on Earth. In 1985, desert heat, car-breaking conditions and dangerous sandstorms left the competitors battling against all odds to reach the finish.

From the snow and ice of the Atlas Mountains to the baking heat of the Sahara Desert, this action-packed review follows the 572 cars, motorcycles and trucks as they tackle the 14,000km adventure. In the toughest Dakar Rally yet, the route proved too much for many - just 77 competitors would last the full 22 days.

As favourites including the Porsche 959s of Jacky Ickx, Jochen Mass and 1984 winner Rene Metge joined the casualty list, the Audi Quattros, Land Rovers and even two-wheel-drive Opel Mantas took turns at the front. However, it was the reliable Mitsubishi Pajeros of Patrick Zaniroli and Scotsman Andrew Cowan which would go the distance in this extraordinary rally.

As Hubert Auriol and Cyril Neveu struggled, the battle for victory in the bike section came down to a ferocious fight between the BMW of 1984 winner Gaston Rahier and the Yamahas of Jean-Claude Olivier and Franco Picco.

Spectacular footage delivers all the drama as the cars, bikes and trucks battle with the terrain, while interviews with the stars take you behind the scenes of one of the toughest rally raids ever.
