The new Audi RS 3 is the first Audi model with a torque splitter. This technology makes fully variable torque distribution between the rear wheels possible. Unlike the previous rear axle differential with upstream multiple disc clutch package, the torque splitter uses one electronically controlled multiple disc clutch on each of the respective drive shafts. This ensures that the right amount of torque is optimally and continuously distributed along the rear axle.
During dynamic driving, the torque splitter increases torque delivered to the outer rear wheel with the higher wheel load, which significantly reduces the tendency to understeer. In left-hand curves, it guides 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 difference in propulsive forces means that the new RS 3 turns into curves even better and follows the steering angle more precisely. This results in optimal stability and maximum agility – especially when cornering at high speeds. The torque splitter compensates for oversteer by directing the torque to the wheel on the inside of the curve or to both wheels. If the driver takes his or her foot off the accelerator, the engine’s drag torque is also distributed along the rear axle. When coasting, controls are also in place to maintain driving agility and stability. If faster deceleration is initiated via the brake pedal, both of the torque splitter’s clutches are opened.
In order to maximize its effect, the torque splitter has its own sensor system. Each of the two multiple disc clutches has its own control unit, which use the electronic stabilization control’s wheel speed sensors to measure the wheel speeds. Other influencing factors include longitudinal and lateral acceleration, the steering angle, the position of the gas pedal, the selected gear, and the yaw angle, i.e. the rotational movement around the vertical axis.
On the one hand, the torque splitter increases safety in everyday use, and on the other it enables faster lap times on the racetrack. Frank Stippler, Audi Sport racing and development driver, proved the latter on the 20.832-kilometer Nürburgring-Nordschleife in June 2021. At the wheel of the RS 3 Sedan, he set a new record in the compact segment with a lap time of 7:40.748 minutes.
The Audi drive select dynamic handling system boasts two completely new RS 3-specific modes: RS Performance for the racetrack and RS Torque Rear, a drift mode for use on closed roads. In addition to the familiar comfort, auto, dynamic, and RS Individual modes, the RS 3 also features the efficiency mode for the first time. Depending on the selected mode, the characteristics of important powertrain and chassis components change from an emphasis on comfort to highly dynamic to even optimized specifically for the racetrack. In addition to the torque splitter, Audi drive select also has an effect on the engine and transmission characteristics, steering assistance, electronic stabilization control, the exhaust flaps and, optionally, the adaptive suspension. Different characteristic curves for each of the aforementioned systems create a broad range of driving experiences.
The ultimate in driving dynamics can be experienced in dynamic mode and in the new RS 3-specific RS Torque Rear mode. In dynamic mode, all of the components are configured for a sporty ride. The driver feels this in a more direct steering response and particularly agile handling for dynamic driving with a clearly perceptible engine sound.This mode tends to transmit as much drive torque as possible to the rear axle. The gearshifts of the S tronic are shorter, acceleration even sportier.
This is taken to perfection by the RS Torque Rear mode, which enables controlled drifts and sporty driving with lateral dynamics. It is specially designed for closed roads. The highly rear-heavy distribution of the engine power leads to oversteering behavior, with up to 100 percent of the drive torque directed to the rear ending up at the wheel on the outside of the curve – up to a maximum of 1,750 newton meters. In addition, the engine’s characteristic curve is also modified in RS Torque Rear – and is even more pronounced than in dynamic mode. The same applies to RS Performance mode, which is specially designed for the racetrack. In both modes, the idle speed has been increased even further compared with the dynamic profile to enhance off-the-line performance. The throttle response is even more direct and has a distinctive load shift. Moreover, drivers experience very late upshifting and early downshifting as well as optimal control of the linear accelerator at the apex of a curve. In addition to the specific engine and transmission setup, RS Performance mode is also specially calibrated to the Pirelli P Zero “Trofeo R” semi-slick tires, which are optionally available factory-mounted for the first time.
