Yahoo Autos Audi RS 6 Avant Performance and RS 7 Sportback Performance models revealed
An extra dose of Performance (with a capital P) is coming to the Audi RS 6 Avant and Audi RS 7 Sportback. That’s right, Audi just revealed “Performance” versions of each model that will make both already-hot cars even hotter.
In case you’re in need of a reminder, an Audi “Performance” model is a version of an RS model that’s even more aggressive, powerful and sharper. All of the changes we’ll describe below apply to both the RS 6 and RS 7.
Audi begins the makeover with the 4.0-liter twin-turbo V8 under the hood. It gets larger turbochargers and an increase in boost pressure, resulting in an extra 30 horsepower and 37 pound-feet of torque. The new totals for both models are 621 horsepower and 627 pound-feet of torque. This matches the Mercedes-AMG E 63 S Wagon in torque, and bests it in horsepower. The 0-62 mph time is reduced by 0.2 second, getting it down to just 3.4 seconds.
Audi’s 8-speed automatic transmission is re-tuned for faster shifting times and a more noticeable spread in behavior between drive modes. A new center-locking differential is used that is both lighter and more compact — Audi says it can distribute up to 85% of drive torque to the rear axle. The new differential is also said to improve handling with “more precise cornering” and “less understeering at the handling limits.”
Weight reduction efforts are minimal but still present. Audi says it’s removed insulation in the engine compartment, interior and in the rear of the vehicle to enhance the in-cabin sound. This reduces weight by 17.6 pounds. Where you’ll really see weight chopped off the new Audi Performance models is if you opt for the newly available (and exclusive to Performance) 22-inch 5-Y spoke design wheels. The new wheels feature a design aimed to aid brake cooling, and fitting them chops 44 pounds of unsprung weight versus the regular cars’ 22-inch wheel option. Assuming you do opt for the lightweight wheels, Audi fits them with new, sticker rubber in the form of Continental Sport Contact 7 285/30/22 tires. Audi says these tires result in braking distances from 62-0 mph that are up to 6.5 feet shorter than the standard tires.
