You may never be able to buy one of these beauties, but if Saab introduces the design flair of the Aero X Concept into its other cars, well, there will be no talk of GM cutting it’s Swedish luxury brand out of the action. Debuted at the 2006 Geneva Auto Show, the Saab Aero X Concept is a two-seat, all-wheel-drive concept featuring a carbon fiber body and a 400-horsepower, twin-turbocharged V6 engine. It’s set up to burn ethanol, which is GM’s latest kick, to be sure. Look for traces of the Aero X Concept in the next 9-3, slated for introduction in 2008.
