Mercedes previews technology before Frankfurt auto show

Future Mercedes will crash less often and use less gas doing so. We got a few insights into exactly how that will happen when we attended the Mercedes preview the night before the Frankfurt auto show. Inside its own enormous hall at the International Auto Austellung, Mercedes previewed gas-saving and accident-avoiding technologies we can expect to see on production cars within the next decade.

E85 makes inroads on cost and availability

Three years ago, we embarked on a Midwest road trip in search of what was then the Holy Grail of fuel: E85. Our findings weren't too positive--there were far more E85-compatible vehicles on the road in 2006 (5 million) than there were E85 pumps to fuel them (about 700 out of some 200,000 fuel stations nationwide). In addition, those burning the mix of 15 percent gasoline and 85 percent ethanol were paying a pretty penny for their earth-friendly ways, losing about 15 percent in fuel economy while often paying the same price as regular unleaded.

Concept Car of the Week: Oldsmobile Aerotech (1987)

In late 1984, Oldsmobile management had so much confidence in the potential of its new inline four-cylinder engine Quad 4, that a small team was assigned to the creation of the Aerotech, a research vehicle designed to demonstrate the engine's performance by setting a new world speed record. Ed Welburn, then assistant chief designer, was mostly working on the 1988 Cutlass Supreme but his passion for race cars made him the ideal candidate to be handed the assignment by Oldsmobile 2 studio's chief David North. Inspired by Le Mans racers such as the Porsche 917LH and Jim Hall's Chaparrals, he designed a long, flowing car that immediately seduced design director Chuck Jordan and GM management.
