Pininfarina Air Flow helmet unveiled

This is Pinifarina's Air Flow, a special helmet created by the famed Italian design house for luxury lid manufacturer Newmax, and the star attraction on its stand at the Milan International Motorcycle Exhibition.

GM recalls 1.5 million vehicles for oil leak

General Motors is recalling nearly 1.5 million Buick, Chevrolet, Oldsmobile and Pontiac mid-sized cars equipped with a 3.8-liter engine because an oil leak could start an engine fire.
