Audi is upping the potency of its already extreme RS 6 Avant and RS 7 by introducing new Performance models that boast increased engine output and numerous RS-spec equipment as standard. The engine remains Audi’s ubiquitous turbocharged 4.0-liter V-8, whose output here has been bumped up to 605 horsepower and 553 pound-feet of torque, up from 560 hp and 516 lb-ft in the stock RS 6 and RS 7.

With the new output, the cars will accelerate from 0-62 mph in just 3.7 seconds, down from 3.9 seconds for the stock RS 6 and RS 7, and from 0-124 mph in 12.1 seconds, down from 13.5 seconds for the stock models. Top speed is governed to 155 mph but with an available Dynamic Package this figure is lifted to 189.5 mph.

Making up the rest of the drivetrain is an eight-speed automatic transmission and quattro all-wheel-drive system. In normal driving conditions, 60 percent of the drive torque is sent to the rear wheels for a rear-biased feel. RS 6 and RS 7 Performance buyers can also opt for Audi’s Sport Differential which can further split the torque between the rear wheels.

Other performance features include air suspension with adjustable dampers, 21-inch wheels and ventilated steel brake discs. Available upgrades include stiffer Dynamic Ride Control suspension, Dynamic Steering with a continuously variable steering ratio, and carbon-ceramic brake discs. Many of these vehicle systems can be controlled by the Audi Drive Select system, which on the Performance models features a controller on the multifunction steering wheel—just like in the R8 supercar.

Only die-hard Audi fans will be able to tell the Performance models apart from the stock versions. Unique visual touches include a matte titanium finish on some exterior parts and an exclusive Ascari blue metallic paint finish. Inside, the cars come standard with sports seats with pronounced side bolsters and integrated head restraints. These can be ordered in a combination of Alcantara and leather, and with contrast stitching. Finally, the dial instruments feature black faces, white dials and red needles.

Audi is yet to announce availability in the United States but we can expect the RS 7 Performance to be offered here for the 2016 model year. Sadly, we won’t get the RS 6 Avant Performance here since Audi has determined that American buyers don’t want wagons.
