Compact body. Big performance. The Audi RS 3 Sedan packs the world's most powerful five-cylinder engine under its bonnet, with the 2.5L unit producing 400hp. Paired with a seven-speed S-tronic transmission and quattro all-wheel drive, it moves from 0-62 in 4.1 seconds on its way to a top speed of 174 mph. The interior is outfitted in black leather, with optional sport seats, and has all the technology features you'd expect.
