If there's anything the 580-horsepower Audi RS6 Avant isn't lacking, it's power. But according to AutoTelegraaf, Audi plans to launch a "Plus" version of its insane estate towards the end of the RS6 life cycle. According to the Dutch site, Audi insiders said that a new "Plus" version would go on sale sometime in 2011, just as the A6 is about to get a mild facelift. The "Plus" will supposedly receive tweaks to its suspension and engine, with the V10 producing 613 horsepower.
This wouldn't be the first time Audi offered a "Plus" variant of the RS6. The original, C5-based RS6, built from 2002 to 2004, got a boost in output during the last three months of production, netting an additional 30 hp (from 450 hp to 480 hp), through the use of a remapped ECU and two additional radiators mounted behind the intercoolers. The Plus version also benefited from standard DRC, 19-inch wheels and a sports suspension that dropped the wagon 10mm. Production was limited to just 999 units.
