The Audi RS6 Avant and RS7 Sportback certainly aren't hurting for power. Their 4.0-liter, twin-turbo V8s offer mountains of muscle as tall as the Alps. However, the engineers at the Four Rings are pushing those peaks just even higher for the new Performance versions of the pair. Tweaks to the engine management, bring horsepower up to 597 ponies and 516 lb-ft of torque. Temporary overboost can take the twist to 553 lb-ft, though.
This high-performance duo can haul passengers with aplomb by hitting 62 miles per hour in 3.7 seconds – two tenths quicker than a regular RS. Even more impressive, the 12.1-second run to 124 mph also takes 1.4 seconds less than the standard version. Top speed remains the same 155 mph, but the optional Dynamic Package takes off the limiter to let the RS6 reach 174 mph and the RS7 go 189.5 mph.
The eight-speed tiptronic remains from the standard RS versions, and it routes power through the Quattro all-wheel drive system with a 40:60 front-rear split. An optional sport differential at the back can also provide some extra assistance. Both Performance models come standard with an adaptive air suspension, but for those willing to spend a little more a stiffer RS sport suspension plus with Dynamic Ride Control is available, as well.
The Performance pair launches in Germany at the beginning of November, but there's reason to get excited in the US, too. Audi spokesperson Mark Dahncke confirms to Autoblog that the RS7 Performance is coming here. More details about it should arrive around the Los Angeles Auto Show, he said.
