Introduced in 1999, the Audi RS4 placed itself at the top of Audi’s compact car lineup. With a sportier, more aerodynamic exterior, exclusive features on the inside, and a more powerful engine, the RS4 quickly became a solid competitor for the BMW M3. However, unlike BMW, Audi also built a wagon version a created a brand-new niche for performance grocery getters. The RS4 Avant become such an important car in the Audi lineup, that the third-generation RS4 didn’t even get a sedan version. Come 2017 and a brand-new generation RS4 arrived, also introduced with an Avant variant only.
