Chevrolet WTCC Ultra concept

Chevrolet has released a sketch of their WTCC Ultra concept that will be unveiled at the Paris Motor Show in three weeks. Styled by Ewan Kingsbury of GM Australia, who also worked on the Holden Torana, the concept was further developed in Europe to produce a fully working prototype, while the engine comes from Korea and the body from Japan. The international collaboration demonstrates the breadth of GM's resources, and has resulted in Chevrolet's vision of a new generation of World Touring Cars.

World's most expensive Alfa Romeo sold at auction

The Alfa Romeo that was the brainchild of Mussolini has sold for nearly £6m at auction. The Italian dictator commissioned the Alfa Romeo 8C-35 to conquer Hitler's dominance of pre-war racing. Built in time for the 1935 Italian Grand Prix, the 8C-35 smashed the competition with racing star Tazio Nuvolari at the wheel and confirmed its fate as one of the most successful racing cars ever. At last weekend's Goodwood Revival, the 8C-35's place in the history books was confirmed as it became the most expensive Alfa Romeo ever to sell at auction. Selling for £5,937,500, the Alfa Romeo eclipsed the previous record of £4,245,118, held by a 1933 8C 2300 Monza, sold in 2010.
