2021 Audi RS6 Avant is a 591-horsepower wonder wagon

Having a friend who owns a station wagon is like having a friend who's a vegan or who owns a rescue dog: You're never going to hear the end of it. 

The era of crossovers has given these low-slug longroofs new life among a small but vocal subset of automotive fans who want you to wake up and realize that not everybody needs a sun-blotting SUV. 

The 2021 Audi RS6 Avant is treated like a demigod in this circle, and for good reason: It combines ample storage and enough torque to affect plate tectonics in a package that makes for one of the most compelling daily drivers for sale today.

The RS6 Avant has a single competitor in the US: The Mercedes-AMG E63 S Wagon, which costs a little more and produces a little more power while returning quicker acceleration figures (3.0 seconds to 60 mph versus the Audi's 3.5) and offering a few extra cubes of cargo capacity.

That said, the Merc's aesthetics are far more subdued inside and out, so it's mostly a manner of personal taste, especially at this price stratum.

If you really dislike wagons for some reason, there's always the RS7, too.

Fast wagons are few and far between, and the RS6 Avant is usually relegated to forbidden fruit status in the US, so consider this one a special treat. 

With performance chops to spare and a properly luxurious interior that can hold more than you'd expect, there's a good reason why people fawn over the RS6. 

If you aren't quite ready to embrace the crossover life, this middle-grounder presents a hard opportunity to pass up.
