The BMW M5 is back!

BMW's M division has gone back to the drawing board with the M5, giving the fifth generation of the iconic four-door a twin-turbocharged 4.4-liter V8 engine—the first time Munich's class-defining performance sedan has gone without a naturally aspirated powerplant since its introduction in 1984. Further changes see it adopt a dual-clutch gearbox as part of a complete driveline rethink that resigns the old model's sequential manual transmission to the history books. Revealed here officially for the first time, the new M5 is planned to make its world debut in concept-car guise at the Shanghai motor show later this month.

GM recalls nearly 15,000 Buick LaCrosse, Chevrolet Impala sedans

General Motors is recalling about 15,000 vehicles to fix two problems--reprogramming the electronic stability control in some 2012 Buick LaCrosse cars and rerouting the power-steering hose on the 2012 Chevrolet Impala. The automaker is recalling 10,344 Impalas to reroute the upper power-steering house that could fail because of heat from the catalytic converter. As a result, the hose sprays fluid over the catalytic converter, causing smoke and potential fire.
