Abt Sportsline has introduced a new tuning program for the Audi RS6 Avant.

On the styling front, the company offers carbon fiber mirror caps and a sports exhaust system. Customers can also order Abt-branded valve caps and "entrance lights" which project the Abt logo onto the ground.

Interior changes are limited but the company offers black floor mats with a silver embroidered Abt logos.

Last but not least, there's an optimized ECU which enables the twin-turbo 4.0-liter V8 engine to produce approximately 666 HP (490 kW) and 830 Nm (612 lb-ft) of torque - an increase of 106 HP (78 kW) and 130 Nm (96 lb-ft) of torque. This should enable the model to accelerate from 0-100 km/h in less than 3.9 seconds, before hitting an increased top speed of 300 km/h (186 mph).
