GM says natural-gas Chevrolet Impala on the way

General Motors said it will sell a version of the Chevrolet Impala sedan with the ability to switch between gasoline and natural gas, part of the automaker's plan for taking advantage of a U.S. drilling boom that has made natural gas a more viable fuel for cars.

New BMW 3-series bows, performance-oriented 335iS joins the lineup

A new performance-oriented 335iS model endowed with an M-sport styling kit and unique chassis settings heads the list of changes BMW brings to its facelifted 2011 3-series coupe and convertible. Set to slot into the lineup between an upgraded 335i and the M3 when it goes on sale in March as an exclusive for North America, the 335iS runs a tuned version of BMW's N54 engine, as found in the recently unveiled Z4 sDrive35iS, coupled to either a standard six-speed manual or an optional Getrag-engineered seven-speed dual-clutch gearbox. The twin-turbocharged 3.0-liter inline six-cylinder engine of the 335iS adds a special software package to bump power to 326 hp and lift torque to 332 lb-ft--or to an even gutsier 369 lb-ft for short periods via an overboost function that unleashes added turbocharger boost pressure.
