ABT Sportsline is among the first to apply their customisation skills on the 2011 Audi A6, and if you wants to see how their new upgrade program looks like in real life, then you should stop at their stand at the 2011 Geneva Motor Show.
Besides a slightly modified front spoiler lip, along with new side sills, and the restyled rear apron which integrates the quad exhaust pipes, the ABT 2011 Audi A6 has also been fitted with the tuner’s newly designed light alloys which comes in sizes 19 to 21 inch, and wrapped with hi-performance tires.
There are currently two power packages available for the 3.0-litre TDI version 2011 Audi A6, which increase the the car’s output to 282 HP (207 kW) and 310 HP (228 kW / 610 Nm of torque) respectively from 245 HP (180 kW). Additionally the tuner is working on a program that will dial up performance on the 3.0-litre TFSI version, with the promised results being 410 HP (302 kW) instead of 200 HP (221 kW).

ABT press release :
Built to be outstandingly quick – The new ABT A6
6 is a powerful number: If you throw a six in Ludo, you reach the goal quicker, and the same also applies if you drive an ABT A6. Power and comfort make the premium car a perfect everyday companion. Long journeys can be managed with ease, but the fun already begins on short trips. Regardless of whether you choose a petrol or diesel engine, the A6 becomes a veritable sports car with a performance improvement from ABT Sportsline. In the developments for the new model from the successful A6 range, the world’s largest tuner of vehicles from the VW group also ensures that the character of noble superiority is not just retained, but is accentuated even further.
Thanks to ABT POWER, the 3.0 TDI offers a  high-torque and cultivated 282 HP (207 kW) instead of the series standard 245 HP (180 kW). An ABT Turbocharger is additionally used in the ABT POWER S package, giving the diesel 310 HP (228 kW). 610 Nm torque ensure that the A6 can "cope playfully" with any situation. The professionals are currently working full out to develop a performance improvement for the 3.0 TFSI: The petrol engine will then bring a powerful 410 HP or 302 kW onto the road (series standard: 300 HP / 221 kW).
Visually it is also clear exactly where the new ABT A6 comes from: From the back it confidently shows its rear skirt with the typical four tailpipe look of ABT Sportsline. The rear spoiler adds to the elegant appearance of the car and gives it an even sportier look. The side skirts and front spoiler underline the other “sweet sides” of the successful Ingolstadt design. "For us the A6 is an extravagant, straight-forward car, which doesn’t show off yet also doesn’t hide away," states Hans-Jürgen Abt. For the General Manager of the traditional company which recently celebrated its 115 year anniversary, the A6, which has been further developed specifically to reduce its weight, is a great success: “It is just the prefect choice for our demanding customers.”
The appearance of the new A6 can be rounded off perfectly with the alloy creations from ABT Sportsline: The designer light alloy wheels are available in 19 to 21 inch and, of course, in combination with fitting high-speed tyres. Which wheel you choose in the end is
of course a matter of taste, but all the models suit the classy-dynamic appearance of the ABT A6 harmonically. One thing remains unchanged: Throwing a 6 may make you happy in the short-term, but the ABT A6 gives you lasting enjoyment.
