  • 2012 Mercedes-Benz S 350 Bluetec

    What can you say about driving a Mercedes-Benz S-Class? It's luxurious, smooth, powerful, packed with features, impressive on the road, and very, very large. Now you can add another adjective: green. While the S 400 Hybrid has been in the mix for two years, Mercedes-Benz is launching a clean-diesel version of the S-Class for 2012. The 2012 Mercedes-Benz S 350 Bluetec ears EPA ratings of 21 mpg city, 31 mpg highway, for a combined rating of 25 mpg--versus the 19 mpg city, 25 mpg highway, and 21 mpg combined ratings of the hybrid S-Class. 700 miles of range With its 22-gallon fuel tank, the...

    Outdated Tests Skew CAFE Gas Mileage Ratings: 48-MPH Freeways?

    It's widely accepted in the auto industry that all manufacturers game the test cycles used to establish emissions and gas-mileage ratings.

    Despite lack of an official confirmation from Audi of America, we'd bet significant money on the arrival of the Audi A6 Hybrid in the U.S. market. Why? Because the U.S. has the highest hybrid penetration of any market in the world except Japan, and "hybrid" means "high gas mileage" to a large number of U.S. buyers, particularly the affluent ones who buy imported luxury cars like Audis. It's coming, trust us So while other media have reported that the A6 Hybrid won't be coming to the States, we don't believe it for a second. And now Car and Driver has confirmed it, citing unnamed sources...
