Video: GM's Clay Dean on the future of urban mobility

Clay Dean is the star of a new Faces of GM video, Anticipating the Driving Experience of the Future. The global design director for GM's Advanced Design Group, whose job also entails exploring future transportation design solutions, talks about the need to avoid short-term thinking on urban mobility, as by 2030 60 percent of the world's population will live in cities. As new challenges start to emerge, such as increasing congestion, Dean believes it is time to start thinking about transportation in a completely different way.

2013 Mercedes-Benz SL63 AMG review notes

ASSOCIATE EDITOR JAKE LINGEMAN: The SL-class was my favorite Mercedes for a long, long time -- probably until the SLS AMG debuted. But there's something about this body style that doesn't quite look right anymore. The front still looks great: a little blockier, but cool.

EBay exotic: 1971 Maserati Indy

In honor of the upcoming 100th anniversary of the Indianapolis 500, we bring you this lovely red 1971 Maserati Indy. Styled by Vignale, the Indy served as Maserati’s four-passenger business express from 1969 to 1971, powered originally by a 4.2-liter V8 and later by 4.7- and 4.9-liter versions of the Ghibli powerplant. This Oregon-based Euro-market example has a five-speed manual gearbox and power steering, and the owner of 20 years claims to have had a lot of expensive-sounding work done over the past few years.
