Nissan offers interactive shopping for smartphone users on sales lots

Autoweek in review: What you may have missed

Rain fell all week at One Autoweek Tower, and the breaking news didn't let up, either. Things started out busy enough on Monday with Bugatti losing its top-speed record and the trailer of Ron Howard's new film, “Rush,” hitting the Web. On Tuesday we paid homage to Distracted Driving month by recounting the touching story of a Kansas State Trooper who has witnessed a variety of tragic scenes -- many resulting from distracted driving.

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.
