Drivetrain

The seven-speed S tronic is standard on the RS 3 Sedan* and the RS 3 Sportback*. The lower gears of the compact dual-clutch transmission are dynamically short whilst the seventh gear has a long ratio to reduce fuel consumption. A heat exchanger controls the temperature of the transmission oil whilst a new angle drive at the prop shaft saves two kilograms (4.4 lb).

The driver can let the seven-speed S tronic operate automatically or can change gear themselves using the selector lever or the steering wheel paddles. There is also a choice of two driving programs in automatic mode. In D mode, the engine is optimized for everyday traffic. In S mode, the engine is designed for more agility and the revs are higher. Gears are shifted almost imperceptibly within hundredths of a second. The Launch Control controls starts with optimum traction. With its help, the RS 3 taps into the full potential of its acceleration. Prerequisite: the ESC sport mode must be active and the selector lever in the S position.

Variable power distribution: the quattro drive

The quattro permanent all-wheel drive combines gripping dynamism with considerable stability. Its central component is the electronically controlled, hydraulically activated multi-plate clutch, which is mounted at the rear axle for reasons of axle load distribution. The multi-plate clutch uses software that is tailored specifically to the RS 3. It distributes the drive torque extremely quickly to the front and rear axle as required. Depending on the driving style and coefficient of friction, between 50 and 100 percent of the available drive force can be sent to the rear axle. An electrically driven pump presses the plates in the clutch together with a maximum oil pressure of 40 bar. As soon as the grip on the road is reduced or the driver adopts a more sporty driving style, the clutch can direct some of the drive force to the rear axle when turning into the corner. 

Tuned specifically to the RS: the stabilization control with two modes

The developers have applied RS-specific tuning to the Electronic Stabilization Control (ESC) and the anti-slip control. In addition to the full mode, there is also a sport mode in which the ESC intervenes later. This mode provides additional driving pleasure, and also enables controlled drifting on low-friction road surfaces. If the driver pushes the button for longer than three seconds, the ESC switches off completely to allow particularly sporty handling.

The handling of the RS 3 is perfected by the wheel-selective torque control – an intelligent software function of the Electronic Stabilization Control (ESC). When cornering at higher speeds it slightly brakes the wheels on the inside of the curve which are under less load. Both wheels of the axle can then transmit greater drive torque to the road.
