Mercedes-Benz reveals first C-class details

Mercedes-Benz has revealed limited details about its new fourth-generation C-class sedan, more than two months before it is due to make its world debut at the Detroit auto show. Although the new BMW 3-series and Audi A4 rival is yet to official unveiled -- in fact, all we have so far are interior renderings -- Mercedes-Benz says the new C-class will be a significantly more advanced car than its predecessor in terms of construction, with a “best in class” weight figure and a level of structural integrity that it describes as being “unparalleled” in its class. Among its features is a new lightweight body structure that uses a newly developed aluminum hybrid construction process that Mercedes-Benz claims will shave as much as 220 pounds over the current model depending on the engine it uses.

Chevy Malibu Eco hybrid is a tough sell

Most prospective Chevrolet Malibu buyers at Castle Chevrolet in suburban Chicago quickly decide that they don't want to pay nearly $3,000 more for the Eco mild-hybrid version. "For most people, it's hard to justify the extra money based on the extra fuel economy" of a combined 3 mpg more than the base model, says Jeff Tuckman, the dealership's inventory manager. "You've got the base LS model sitting next to it that's just as nice and luxurious." It's a problem flagged by many Chevy dealers.

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. Under hard braking, engine oil could leak past a heat shield and drip on the exhaust manifold. The National Highway Traffic Safety Administration says that could start a small fire that could spread to a plastic spark plug wire guide and beyond.
