Prior to 2013, the Audi S5 was the hottest version of the automaker’s sexy coupe. This year, the S5 swaps its formerly standard 4.2-liter V-8, which generated 354 horsepower and 325 lb.-ft. of torque, for the same supercharged 3.0-liter V-6 found in the S5 Cabriolet, which makes 333 horsepower and 325 lb.-ft. of torque, the latter over a lower and broader rev range. The result is a 2013 Audi S5 that is just as fast but more fuel-efficient than it was before.
The switch also created room in the A5 model lineup for the new 2013 RS 5 Coupe. The Audi RS 5 Coupe is equipped with a 4.2-liter V-8 engine, like the previous S5 Coupe, but in this application the engine is reworked to rev higher and harder, producing 450 horsepower at a lofty 8,250 rpm.
We’ll talk more about the mechanical upgrades later in the review. For now, with the introduction of the 2013 RS 5, you can rest assured that Audi has a proper alternative to other high-performance luxury coupes.
