The new Audi RS 3 is the first Audi model that comes standard-equipped with a torque splitter. It replaces the rear axle differential and the previous multiple disc clutch package on the rear axle. Instead, an electronically controlled multiple disc clutch is used on each of the drive shafts. This ensures that the right amount of torque is optimally distributed along the rear axle. During more dynamic driving, the torque splitter increases the drive torque to the outer rear wheel with the higher wheel load, which significantly reduces the tendency to understeer. In left-hand curves, it transmits the drive torque to the right rear wheel, in right-hand curves to the left rear wheel, and when driving straight ahead to both wheels.
The new technology also makes controlled drifts on closed-off tracks possible – in this case, the torque splitter directs all of the power to only one of the rear wheels, with up to 1,750 newton meters per wheel possible. Audi even developed a driving mode specifically for the RS 3 for this purpose – “RS Torque Rear” – as a drift mode with its own characteristic curve for the torque splitter. The RS Performance mode, created specifically for the racetrack, is another never-before-seen innovation. It uses a specific engine and transmission configuration and is precisely tailored to the semi-slick tires that are, for the very first time, available for the RS 3 as a factory option. In this case, the torque splitter delivers a particularly dynamic, sporty ride along the longitudinal axis with as little understeer and oversteer as possible. These modes can be selected via the Audi drive select driving dynamics system, which also offers the following profiles: comfort, auto, dynamic, RS Individual, and efficiency.
With its five-cylinder, high-performance engine, the Audi RS 3 is one-of-a-kind in the segment. The 2.5 TFSI has won the “International Engine of the Year” award nine times in a row. In the latest generation of the compact sports car, the engine is now more powerful than ever before. The new RS 3 models sprint from zero to 100 km/h in just 3.8 seconds. Their top speed is limited to 250 km/h, but 280 km/h is also available as an optional upgrade. With the RS Dynamic package and ceramic brakes, they can even reach a top speed of 290 km/h. This makes the Audi RS 3 the best in its class in terms of acceleration and top speed. This is primarily due to the 500 Nm increase in torque, which is available between 2,250 and 5,600 rpm. That is equal to 20 Nm more than its predecessor. As a result, the Audi RS 3 accelerates even faster from low rev ranges.
The engine’s maximum power of 294 kW (400 PS) is available earlier than before at 5,600 rpm and extends over a broad plateau to 7,000 rpm. A new engine control unit also increases the speed at which all of the drive components communicate with each other.
