ABT Sportsline has unveiled their new tuning program for the facelifted Audi S6 Avant.

Designed to offer RS levels of performance, the package enables the twin-turbo 4.0-liter V8 engine to produce 550 PS (404 kW) and 680 Nm (501 lb-ft) of torque - an increase of 100 PS (73 kW) and 130 Nm (95 lb-ft). There's no word on acceleration times but the company increases the top speed to 290 km/h (180 mph).

Customers can also order carbon fiber mirror caps, a carbon fiber reinforced plastic rear spoiler and a variety of 20- and 21-inch alloy wheels.  The company also offers ABT-branded floor mats, steering wheel-mounted LED shift lights and a Level Control suspension module which reduces the ride height 20mm front / 15mm rear.
