If you find the base version of the Audi A7 somewhat unexciting with its 333-horsepower, 3.0L V6, there's still a 450-horsepower, 4.0L V8 in the S7, or even the 560-horsepower RS 7 to snatch you out of the doldrums. And if that still doesn’t do it for you, for a modest supplement you can opt for 605 horsepower in the RS 7 with the Performance Package. A scant 3.6 seconds is all it takes to go from 0 to 100 km/h.
