2010 Cadillac SRX: A new standard for GM's luxury crossovers

A few years after Lexus touched off the luxury-crossover craze with its RX 300, Cadillac chose to offer the SRX--a completely different, angular tall wagon with a rear liftback built on its rear-drive CTS sedan chassis. Although the SRX was excellent, its showing in a marketplace seeking stylish RX-like crossovers wasn't good. Since it introduced the SRX as a 2004 model, Cadillac has sold a total of 120,000; Lexus sells about 90,000 RXs every 12 months.

New technology combats drowsy driving

Auto supplier Takata is introducing a new driver-alertness warning system to the commercial trucking industry to keep drivers awake. The SafeTrak electronic vision system sounds an alert if a trucker is driving erratically or unintentionally drifting from a lane. A recent AAA study for traffic safety found that drowsy driving is a contributing factor in 16.5 percent of fatal car crashes 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.
