Hot on the heels of the 2018 Audi Q5 unveiled at the Paris Motor Show are two new Audi RS models. Sticking true to their “RS” brand, the two have high performance within their cross hairs. One is even an honest to goodness race car. The Audi RS 3 this year, however, is stirring things up a bit by introducing the first Audi compact sedan to bear the “Rennsport” moniker. Truly more RS than its A3 sedan predecessor, the Audi RS 3 Sedan oozes performance both without and within, boasting of no less than 400 horsepower.
