Audi has given the RS treatment to its smallest SUV, creating the ultimate junior WAG rocket. It’s fast and that. It’s the first time the RS badge< has been applied to an SUV, in fact – though it comes some time after BMW’s M Division broke this particular taboo by making the X5 M and X6 M. And, of course, AMG has been at it for ages, with its versions of the GL-Class and G-Wagen.In a brilliant fit of corporate management speak, Audi is calling the RS Q3 a “conceptual interpretation”, which uses two long words where “concept” will do.
