Audi QS7 by ABT

In terms of performance, you can boost power and torque for the 3.0-liter TFSI 333 PS unit as well as for the flagship TDI 272 PS unit. Performance gains can also be had for owners of the 218 PS 3.0-liter TDI engine, but that’s not going to get you places as fast as the other two.

On paper, you’re looking at 325 PS and 680 Nm (501 lb-ft) of torque as opposed to 272 PS and 600 Nm (442 lb-ft) if you’re driving the flagship turbodiesel Q7 – which is somewhat of a significant improvement. As for the petrol-powered TFSI engine, you’ll get to enjoy 410 PS as well as 520 Nm (383 lb-ft) of torque, as opposed to the standard 333 PS and 440 Nm (324 lb-ft).
