Mercedes F125 concept (2011) at Frankfurt motor show

Mercedes today unveiled the F125 concept car - a car bearing the three-pointed star's F name to demark it as a tech testbed, and the 125 to mark Merc's 125th anniversary in this four-wheeled business. It's a hydrogen fuel-cell vehicle, and Merc claims a punchy 1000km (620-mile) range. But the scientists here are proud of the cutting edge lithium sulphur batteries, used to store energy created by the fuel-cell.

Audi shifts to eight-speeds for most models

A formal press conference probably won't happen until this summer, but we hear that Audi dealers have received their 2011 order guides, and it looks as though the company will be going from 0 to about 70 percent of U.S. sales being eight-speed automatic transmissions. Beginning this fall, the eight-speed will replace today's six-speed automatic in the A4 2.0-liter turbo sedan and wagon, the A5 2.0-liter turbo coupe and cabriolet, the Q5 2.0-liter turbo, the Q7 3.0-liter turbo, the Q7 diesel, the Q7 with the 3.0-liter supercharged V6 and the all-new A8 and A8L with the 4.2-liter V8.
