BMW: Don't fear the stop/start system in the 2012 3-series

BMW is taking a calculated risk by installing an automatic stop/start system on its best seller, the 3-series, for 2012. But company brass is optimistic that American consumers will adjust to the relatively foreign technology. "Many customers will enjoy the car very quickly," said BMW board member Ian Robertson, who oversees sales and marketing.

Volkswagen NCC concept

Volkswagen's New Compact Coupe (NCC) concept previews the next Jetta, but with two-doors rather than four. The car's front - minus the hybrid-style closed grille - pretty much represents the new face of the sixth-generation production Jetta due on sale this November, and its syling is informed by the latest Polo as well as some recent concepts from the German brand. Read our opinion of the NCC concept's design in our 2010 Detroit Auto Show Highlights, and see more photos of the showcar in the photo gallery below.

First Sight: Mercedes-AMG GT

“If I was to buy any sports car that wasn't a Mercedes, it'd be a Porsche 911,” says Mercedes' head of design, Gorden Wagener. “But when you see the two cars together, we think ours has the edge.” He's talking about the new Mercedes-AMG GT, a front-mid engined, two-seater sports car that's unashamedly aimed at higher-end 911s, and we've come to see it at Mercedes' Sindelfingen studio.  The GT replaces the larger SLS, and is seen by Wagener as the best example yet of his 'sensual purity' design philosophy: “The SLS is very much [he gestures] line, line with a surface in between. With the GT we started with the surface and worked to refine and reduce the number of lines.” Elements of the SLS's platform have been carried over, so the GT measures the same 1,939mm wide.
