Audi may be about to launch a more potent version of its RS 6 Avant super wagon. Details of a new RS 6 Avant Plus model have appeared on a U.K. Audi dealer’s website and included information that the car will have 600 horsepower on tap.

Ferrari’s latest one-off supercar is the SP America. It’s destined for a customer in the U.S. and features a design inspired by the legendary 250 GTO.

Mercedes-Benz is working on a new generation of its C63 AMG, and once again a wagon version will be launched. We have new photos of the wagon version testing at the Nürburgring.

You'll find all of this and more in today's car news headlines from around the High Gear Media network, right here at Motor Authority.
