Audi combines all front-wheel drive engines with a six-speed manual transmission or, depending on the engine version, with a six-speed S tronic or seven-speed S tronic.
Like all Audi transmissions, the manual transmission is also widely spread – the lower gears have sporty short ratios, while the highest gear has a comparatively long ratio to reduce engine speeds in intercity travel. The six-speed transmission affords precise shifting over short distances and boasts a high degree of efficiency.
Dynamic and comfortable: the seven-speed S tronic
With the seven-speed S tronic the engine speed level in the mode S is slightly higher, while the D mode operates at more moderate rpms.
In cooperation with the optional Audi drive select dynamic handling system (standard with the sport line), there is a freewheeling function in the efficiency mode that further reduces fuel consumption. The selector lever serves manual control of the seven-speed S tronic; the driver can also shift gears using the rocker switches on the steering wheel.
The 2.0 TFSI engines* are accompanied by a totally newly developed seven-speed dual-clutch transmission with two wet clutch systems. It supersedes the previous six-speed dual-clutch transmission and is designed for higher torque values.
The new Audi A3 distributes the engine power to the front wheels by as standard. Among the gasoline-engined versions quattro all-wheel drive is available for the 2.0 TFSI*, and for the 2.0 TDI* and above among the diesel-engined models.
Power intelligently distributed: quattro drive
The quattro permanent all-wheel drive distributes the torque to both axles by means of a multi-plate clutch with hydraulic actuation and electronic control.
During normal driving, the clutch transmits most of the engine’s power to the front wheels. Should traction decrease there, it can continuously redirect the torque to the rear within a few milliseconds. A piston compresses the plate packages in a controlled way; the required oil pressure is built up by an electrically operated axial piston pump and can reach almost 40 bar.
For the Audi S3*, engineers have specially tuned the quattro drive which comes as a standard feature, just as has already been done on the Audi TT and RS 3*. The control philosophy particularly takes into account variables in the driving dynamics. It is also based on the status of Audi drive select and Electronic Stabilization Control (ESC). The result is more frequent and pronounced torque distribution to the rear axle, which additionally supports the sporty driving characteristics of the Audi S3. During load changes, the distribution of torque allows precise turning into the bend.
When drifting on a low-friction road surface, it provides for maximum control, traction and reliability. The front axle straightens out the car again when exiting the corner.
