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.

2011 BMW X3 leaks

The 2011 BMW X3 - together with required camouflage To say that details have leaked is a bit disingenuous, as the leak has emanated from BMW. So although technically I suppose we should call it a leak because the details are not exactly concrete – and the photos are of camouflaged cars – it’s more of a tease than a leak. The photos tell us not a huge amount – it’s a new BMW X3 with some black and white bits on.

BMW Alpina B6 Bi-Turbo Convertible (2011) at the Frankfurt motor show

BMW’s M Division is busy readying M6 variants of both the 6-series Coupe and Convertible, but if you can’t wait until 2012 – or if you want a fast but understated Six – then Alpina has just the car for you. It’s the BMW Alpina B6 Bi-Turbo Convertible, just unveiled at the 2011 Frankfurt motor show. And I’m guessing the BMW Alpina B6 Bi-Turbo Convertible does exactly what is says on the tin?
