@speedcheck.cars: There's something special about the sound of an Audi five-cylinder. Today we're testing the top speed of the Audi RS3 Sedan 8Y, powered by its legendary 2.5-liter turbocharged five-cylinder engine producing 400 PS and 500 Nm of torque. With quattro all-wheel drive and that unmistakable five-cylinder soundtrack, this RS3 is one seriously impressive performance sedan.
