2018 Audi S7 vs. Its Competition

2018 Audi S7

There's not a bad choice in the Audi S7 and RS 7's competitive set, to be honest.

But we really do like these two for their unique style and their monstrous V-8 engines.

The Mercedes-AMG CLS63 S comes closest in terms of style and panache and its twin-turbo V-8 is just as thrilling as what you'll find in the Audis.

The BMW M6 Gran Coupe is a close facsimile, but ultimately isn't quite as entertaining to drive—something we admit with chagrin when it comes to some modern BMWs.

But don't count out the Cadillac CTS-V.

Perfected over three generations, Detroit's German-style hot-rod outdoes its immediate sedan rivals even if it doesn't have quite the sexy shape of the Audis.
