The RS 4 Avant takes the notion of a wagon being some sort of sedate family transporter and tosses it right out the window. It might be surprising to hear but, in its time, this was the most powerful production car Audi ever built, with a 375-hp twin-turbo V6. This isn’t just some monster they released to scare grocery-getters; the RS 4 Avant is a true sports car despite its ample room in the rear. Bespoke body panels surround oversize tires, enlarged brake rotors sit behind every wheel, and the suspension is lively and responsive. This speedy wagon is ready for a trip to grandmother’s house; just make sure the road over the hills and through the woods has plenty of twists and turns to enjoy.
