The Ingolstadt-based automaker decided they should hold the honor of having the most powerful series produced diesel SUV in the world – so they took the 2.3 ton crossover out with an all-new 2.0-liter twin-turbo TDI engine.
The model wasn’t just content on being the most powerful, it also premiered an interesting technology – the use of an electric air compressor which has the task of removing any turbo lag. But as always, the engineers actually refrained from putting out the entire potential of the motor – which is something well known aftermarket specialist ABT took profit in. The tuner actually fiddled with the electronics and got 520 PS and 970 Nm of torque – which is more than what a Mercedes-AMG GT S has to offer from the same size of petrol engine. It’s also a sizeable boost from the standard 435 PS and 900 Nm of torque – so ABT was able to lower the sprint time to 62 mph (100 km/h) from 4.9 to 4.6 seconds.
Because we’re dealing with a diesel – not the most rewarding in terms of soundtrack, ABT decided to go for another electronics play – adding to the model’s standard active sound system a Sound Control unit. In terms of design ABT is one of those tuners believing less is more – so they opted for Level Control to get the SQ7 down 20 mm and also offer a wide range of alloy wheels to match customer preferences.
