Visual differences aside, the real story is in the RS6's performance potential. Sources predict the addition of a turbocharger to the S6's 5.2-liter V10 engine, which should generate something between 550 and 600 horsepower.

New prototypes for the Audi RS6 have been spotted in Germany, this time basically undisguised. Now that the car is free from the annoying black-and-white checkered camouflage, the extent of the changes over the Audi S6 are now clearly visible. The LED light strips on the S6’s front bumper have been removed on this RS6. New front air-intakes are larger, and they wrap around the front bumper allowing for some integrated brake cooling ducts up front. The front intakes are highlighted by low flares which continue along the side, between the wheels, making for a more aggressive stance.

The rear bumper has been reworked significantly. Large single exhaust pipes replace the S6’s dual-tip design, and an aggressive rear diffuser dominates the rear bumper.

Given this RS6’s nearly production finish, a debut this Fall at the Frankfurt Motor Show seems likely.
