Remember ABT Sportsline's crazy RS6-R? Well, the tuning firm has now released a more subtle package for the RS6 Avant, which includes the same 544 kW output but without the bold body kit.

In fact, the German firm offers two power upgrades for Audi's twin-turbo 4,0-litre V8, which pushes out 441 kW and 800 N.m of torque as standard. The first ABT Power upgrade increases the peak outputs to 515 kW and 800 N.m and result an improved (claimed) 0-100 km/h time of 3,3 seconds. At the summit, though, is the Power R pack, which boosts the wagon to 544 kW and 920 N.m, resulting in a claimed 0-100 km/h time of just 3,2 seconds.

Regardless of which output the customer chooses, there's also a new stainless-steel exhaust system (complete with 102 mm matte-carbon tailpipes) for a more powerful sound.

For improved dynamics, customers can choose from height-adjustable springs or a V4 adjustable suspension setup, with the latter giving you access to rebound and pressure settings. For those who seek more rigidity, a set of anti-roll bars for the front and rear axles is available.

Changes to the exterior are minimal compared with the aforementioned RS6-R, with the 22-inch ABT High Performance HR22 alloy wheels being the only cosmetic option. Updates to the interior can be installed at the customer’s request.
