ABT are known to push the boundaries on the Audi’s and this is certainly the case. The new Audi RS6 Avant already hits 100km/h in a blistering 3.9 seconds so I do not see the point of tuning it but alas here we have it. Optimizing the ECU allows the twin-turbo 4.0-litre V8 engine to produce about 666hp (490kW) and a warping 830Nm of torque. This is an increase of 106hp over the standard model. I am quite confident in saying this would allow the ABT RS6 Avant to hit 100km/h in 3.7 seconds and going on to a top speed of just over 300km/h. This is just astronomical performance for a ‘station wagon’.
