A special device on the rear axle can change the characteristics of the car at the touch of a button. From neutral behavior to oversteer.

After the recent unveiling of camouflaged prototypes, which revealed the presence of a 2.5-liter five-cylinder under the hood, Audi is adding more interest to the technology of the new RS3 Sportback and Sedan models. And it is already clear that we really have something to look forward to.
For example, the carmaker confirmed that engine power remains at 294 kW (400 hp), the same as the previous generation RS3. However, the power is now available in the range of 5600 to 7000 revolutions, ie 250 revolutions earlier. The torque increases by 20 Nm to a final 500 Nm between 2250 and 5600 rpm.
The transmission of power to all four wheels is provided by a seven-speed dual-clutch transmission, with which the Audi RS3 should be able to handle acceleration from 0 to 100 km / h in just 3.8 seconds. The maximum speed should then reach 290 km / h. The new generation of RS3 should be able to beat, for example, the Mercedes-AMG A45 S 4Matic, which accelerates 0.1 seconds longer.

However, the way Audi gets power from the bikes on the road is also interesting. The RS3 models will become the first Audi RS to receive a so-called torque splitter – supplied by Magna. It will replace the multi-plate clutch and rear differential used by the previous generation RS3 with all-wheel drive Haldex.
The Torque splitter consists of two electronically controlled clutches, each on one rear axle, thanks to which it can send power exactly to the bike where the car needs it. The new generation of RS3 should be better controllable and faster and more precise in corners. The system will also be able to better distribute power between the axles and between the individual wheels of the rear axle.

In addition, the car will receive its own equivalent of the so-called drift mode, which is offered, for example, by the competing Mercedes-AMG A45 S 4Matic. In the case of Audi, the engine mapping should be modified, the throttle pedal responses faster, the gears and also the all-wheel drive system adjusted. The torque splitter should then be able to send all the engine power to only one wheel of the rear axle, giving the car a tendency to oversteer.

In addition, a special circuit mode should appear in the travel mode selector, which uses special settings of the drive unit. The driving mode was developed with a view to use in combination with Prelli P Zero Trofeo R tires, which are designed for use on circuits or in sports driving.
The icing on the cake will be the exhaust system with an active flap, thanks to which the car will create the appropriate soundtrack for each driving mode. According to Autocar, the offer should include Comfort, Auto, Efficiency, Dynamic, RS Individual, RS Performance and RS Torque Rear modes.

Thanks to the new Torque splitter, the RS3 should lose about 8 kg compared to the older Haldex, yet the new generation will be about 40 kilograms heavier. The carmaker has also improved the chassis, working with the adaptive DCC system, which should be 10 mm lower than the S3, while it should be 25 mm lower than the standard A3.

Disc brakes were also to be improved, with a diameter of 375 mm at the front and six-pin brakes, while at the rear with a diameter of 310 mm and single-sand brakes. However, carbon-ceramic front discs with a diameter of up to 380 mm should also be available at an additional cost.
The complete unveiling of the Audi RS3 is expected in the coming weeks, when the complete price list should also be published.
