Meet the new Mercedes-Benz SL400

This is our first photo of the upcoming Mercedes-Benz SL400 luxury roadster, a model that effectively replaces the SL350 as part of a series of subtle changes brought to the SL lineup. The move aims to goose sales of the luxury roadster two years after it first hit showrooms. The SL400 is powered by Mercedes-Benz's twin-turbocharged 3.0-liter V6 direct-injection gasoline engine unveiled in the E400 early last year.

Ford tries to quiet complaints about diesel engines with new 6.7-liter Power Stroke V8

The first thing you notice about Ford Motor Co.'s new 6.7-liter Power Stroke diesel truck engine is how quiet it is. Standing next to it, you wouldn't know it was a diesel unless someone said so. The engine debuts early next year in Ford's revamped line of Super Duty pickups.

Opel Adam going rallying

Opel is adding a bit of rally credibility to the new Adam by taking it rallying with an Adam R2 rally car for a one-make cup. But perhaps GM Europe are hoping to inject a bit of performance credibility in to the uninspiring mechanical offerings the Adam currently offers with the revelation that they’re making a rally Adam prepared to basic R2 spec, which means a tweak or three from the standard production car. That means upgrades to the engine, suspension, brakes and gearbox to produce an Adam rally car that’s an affordable entry point for young drivers and Opel are aiming to compete in the ADAC Opel Rally cup with the Adam R2.
