The air runs out of run-flat tires

After settling a lawsuit last month with disgruntled owners of Michelin run-flat tires, Honda dropped the tires for the 2010 model year. It was another disappointment for Michelin and other makers of run-flat tires in a 17-year effort to win customers in the United States.

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.

But there have been problems. Like all small car makers, McLaren has to buy-in most of the clever computer whiz-bang stuff all new cars have, which means McLaren’s tech-bods have to work out how to make it all play pretty together.
