ABT's latest kit for the S6 Avant is named the AS6-R.
The tuning package comes with a modified ECU and pair of new turbochargers for the 4.0L V8 bumping the power by 180hp for a total of 600hp and 553ft/lb of torque. 0-100 km/h (0-62 mph) now only takes 3.9 seconds and top speed increased to 310 km/h (192 mph).
There is also an optional stainless steel sports exhaust system and 21-inch alloy wheels. The exterior receives some minor touches including a carbon fiber air intake, mirror covers, fender vents, side skirts, rear spoiler, and rear diffuser.
