ABT Sportsline introduces 700 hp Audi RS6 Avant

Hot on the heels of their appearance at SEMA and their announcement to open a location in the U.S., the German tuning firm ABT Sportsline has unveiled two new versions of the Audi RS6 Avant, dubbed the ABT Power S and ABT Power. Apparently, ABT Sportsline felt that the 560 hp output of the stock 4.0-liter TFSI-engined Audi RS6 Avant wasn't enough, and tuned the ABT Power S version to produce 700 hp. That's a 25 percent increase in power over the stock version.

New Audi Quattro supercar: could this be it?

Audi has released surprise pictures of one of the concept cars it will be bringing to the 2013 Frankfurt Motor Show, on its international media site.

Cadillac ATS

The Cadillac ATS is an all-new, lightweight, rear-wheel drive sedan that aims to take the fight to the dominant BMW 3-Series in the compact premium segment. The ATS gains the latest interpretation of Cadillac's ‘Art & Science' design language, building on the recent, bigger XTS' aesthetics. Fortunately, the ATS' proportions are far more appealing than its awkward bigger brother, with short overhangs, a long wheelbase and wide tracks giving it a good stance.
