Based on the stylish A5, the RS 5 ups performance levels with a high-revving 4.2-liter V8 making 450-horsepower and 317 pound feet of torque. With this engine, the RS 5 propels itself from 0 to 60 mph in 4.5 seconds, and can achieve a top speed of 174 mph. A rear wing deploys at 70 mph to increase downforce.
A few special styling touches and badges set the RS 5 apart, but in an understated way. Unless you know what to look for—or hear its throaty exhaust note—you might not realize you're in the presence of such a special car.
