    The second pillar on which the excellent driving dynamics are built is the elaborate running gear, with McPherson-strut front axle and four-link independent-suspension rear axle. Large 20″ wheels with size 245/45 R20 tyres also contribute to driving fun and safety.

    The dynamic suspension is designed to give sporty, agile handling and a high degree of stability while making cornering distinctly fun. As an additional quality, the running gear impresses with a driving comfort that would satisfy the standards expected in higher vehicle classes.

    The capability of the engine is matched by the potential of the brake system with its large-diameter discs.

    The electromechanical steering system with speed-dependent power steering provides for superlative handling. It combines optimum steering feel with low sensitivity to agitation from the road surface and significantly reduced power consumption.

    The special qualities of the four-link axle are based on the functional separation of the longitudinal and lateral force absorption points. On the one hand, this allows a high degree of lateral rigidity, which favours superior dynamics and driving safety. On the other hand it also allows a high degree of longitudinal suppleness, improving ride comfort.

    Individual springs and shock absorbers provide vertical support. The shock absorbers are located close to the wheels, allowing a very large load width in the luggage compartment. A tubular transverse stabiliser is secured to the subframe with highly rigid bonded-metal rubber mounts. This effectively reduces the body’s tendency to roll and thus positively influences the transmittable lateral forces – ultimately improving the vehicle’s handling.

    The shock absorbers employ the Audi magnetic ride system, an innovative technology that has already impressed in the Audi R8 high-performance sports car and in the TT. Instead of conventional shock absorber oil, a magneto-rheological fluid is used, a fluid whose viscosity is influenced by an electromagnetic field. This effect means that the shock absorber map can be changed at any time simply by applying a voltage to the solenoids.

    Audi magnetic ride exploits this property to ensure that the correct shock absorber force is available in all driving situations and thus optimising ride comfort and driving dynamics. A computer equipped with sensor technology determines the prevailing driving situation in a matter of milliseconds. Here, the driver can choose between two driving programs, depending on whether he wants to drive with a sportier style – requiring low viscosity of the magneto-rheological fluid – or with a greater emphasis on ride comfort.

    Excellent performance, low weight and maximum mileage are offered by the ceramic brakes. Here, the discs are produced from a ceramic material reinforced with carbon fibres – a combination that has long been proven in the aviation industry.

    It only takes a glance to see the ceramic discs against the anthracite grey paint of the special aluminium callipers. The advantage of ceramic brakes over steel discs is the weight saving of some 20 kg, which improves drivability and comfort. The high level of resistance to abrasion allows a service life of up to 300,000 km. However, its most important strength is its lack of sensitivity to extreme loads.
