The 2015 Audi RS 5 continues the German automaker's commitment to fortify its place within the performance luxury coupe landscape. Featuring a stout 4.2L TSI V8, it not only produces a solid 450 horsepower, but it also maintains a relatively impressive 16 mpg in the city and 23 mpg on the highway. A 7-speed automatic transmission allows for split-second shifts, while Audi's award-winning quattro all-wheel-drive comes standard. To help the RS 5 slow from its 174-mph top speed, massive 14.4-inch ventilated brakes are utilized. The RS 5 starts at $70,495 and is available now.
