The RS Avant driving is actually defined by the 2.9 litre TFSi twin turbo V6 engine that produces a massive 450hp of power and 600 Nm of torque for all your tracts and off road fun driving. The strong and rugged exterior design actually explains this car a lot, and just step in and the plush interior welcomes you in the lap of luxury, the front seats are leather black,3 spoke design leather steering wheel, and plenty of features to keep you hooked up on your longer drives and also reasonable boot space. The RS4 Avant is indeed quite a fresh out of Audi’s SUV lineup.
