The twin-turbo V6 hiding under the hood is based on the engine found in the Porsche Panamera 4S, though it develops more ponies and twist in the four-ringed application. Of course, the 2.9-liter TFSI doesn’t sound nearly as good as the 4.2-liter FSI flat-plane V8 of the B8 RS4 Avant, but times are changing at Audi’s Sport division. And Mercedes-AMG. And, of course, BMW M. Put simply, the German establishment is all for downsizing and forced induction.
Stiffer than the former generation and approximately 80 kilograms lighter, the B9 RS4 Avant carries a starting price of £61,625 in the United Kingdom. The United States will miss out on this sporty family wagon, chiefly because Audi can’t make a case for this sort of vehicle when the A4 allroad is struggling in this part of the world. The RS6 Avant doesn’t have a place in the U.S. either.
European customers who wish to unleash the full potential of the RS4 Avant can do exactly that with the RS Dynamics Package. Tick it off the options list, and top speed increases from 250 km/h to 280 km/h (174 mph). For reference, winding the Chevrolet Camaro SS up to its full potential will get you 165 mph.
This sort of performance, as expected, doesn’t get you too far on a full tank of gas. At NEDC-rated 8.8 liters per 100 kilometers, the RS4 Avant drinks fuel in big gulps. To the fast Audi wagon’s defense, it translates to a 17-percent improvement compared to the V8-powered predecessor, so that’s that.
