A major development goal for the suspension system of the Audi A3 was to achieve a high level of agility, sporty handling and high driving comfort without making any compromises on driving dynamics.

The interaction between all specially co-ordinated suspension components contributes to active safety. Even in its basic configuration, the A3 ’13 affords brand-typical driving and vibration comfort with a strong emphasis on sporty attributes. It thus offers a high level of driving enjoyment.

This has been achieved by employing the proven concept of the McPherson front suspension in combination with a newly developed torsion beam and four-link rear suspension. The torsion beam rear suspension is 15 kg lighter than an equivalent multilink rear suspension, in addition to having aerodynamic advantages. Use of the torsion beam suspension or the four-link suspension depends on engine version (power output).

The Audi A3 will also be available at a later date with all-wheel drive in combination with four-link rear suspension. An electronic damping control system based on the established Audi magnetic ride system will also be available as an option.

A weight-reduced electro-mechanical power steering system with speed-dependent steering assistance (Servotronic) is standard equipment in the Audi A3 ’13, as previously in the predecessor model. A variable steering ratio is achieved through the special geometry of the rack and pinion system. The range of newly developed steering wheels extends from the conventional four spoke steering wheel to the three-spoke multifunction sport steering
wheel with leather trim and shift paddles. At 15 and 16 inches respectively, the wheel brakes (engine dependent) are larger than in the predecessor model and provide ample braking power relative to engine output.

The newly developed Continental MK100 ESP system was used for the first time on an Audi model. Adaptive cruise control (ACC) is available for the Audi A3 for the first time in this class of vehicle. The control characteristics of ACC, Servotronic and the electronic damper control system can be adapted to driver input using Audi drive select.
