Choose the correct spec, and the Audi RS7 will have a top speed of 189mph. While the thumping 4-litre V8 has 700Nm of torque and 552bhp. What you're left with is a car that can reach 0-62mph in just 3.9 seconds. Comfort has never been the focal point of the RS range - the new RS7 is better than past models, but there's still room for improvement. The model in the video review has optional sports suspension, which means it has still springs as opposed to adaptive air suspension. However, in dynamic mode it feels unacceptably stiff, while comfort mode will just about do.
