While the A3 and S3 make do with a turbocharged four-cylinder, the RS 3 utilizes a much more potent turbocharged 2.5-liter inline-five. It produces a stomping 401 horsepower and 369 lb-ft of torque — admittedly a modest increase of 7 hp and 15 lb-ft compared to the previous model. Its estimated 0-60 mph time of 3.8 seconds is properly fast, but it's only 0.1 second quicker than the old RS 3. Track warriors should note that the RS 3's top speed ranges from 155 mph in the standard model to 180 mph when equipped with the Dynamic package and carbon-ceramic brakes. As with the outgoing RS 3, a seven-speed dual clutch transmission and all-wheel drive are standard.
Instead of focusing efforts under the hood, Audi engineers turned their attention to handling performance. To that end, the RS 3 now features what Audi calls the Torque Splitter on the rear axle. This revised differential introduces an electronically controlled multi-clutch pack on each half-shaft to distribute power to the rear wheels. There's also a Torque Rear mode, which can shunt all torque through one rear wheel — perfect for inducing tail-happy oversteer on a racetrack.
Other upgrades include a sport-tuned suspension (with adaptive dampers), a more expressive exhaust system and an aerodynamic body kit. Also on the options list are track-ready Pirelli P Zero Trofeo R tires.
