Audi metroproject quattro: Chassis
The second fundamental ingredient for outstanding handling dynamics is supplied by the sophisticated chassis design, comprising McPherson front suspension and four-link independent rear suspension. Large 18-inch wheels with size 225/35 R18 tyres boost both driving pleasure and safety.
The dynamic chassis is tuned for sporty, agile handling combined with excellent stability, and makes cornering a particular delight. What’s more, the chassis excels with a level of ride comfort befitting of higher vehicle classes.
The braking system with its large-diameter discs (measuring 312 mm across at the front wheels) is more than a match for the drive power. Bred on the racetrack, the system promises outstanding, fade-free stopping power.
The electromechanical steering with speed-sensitive power assistance is also a boon for agile handling. The system boasts optimum steering feel combined with low sensitivity to road surface excitation and a considerable reduction in energy consumption.
The specific strengths of the four-link suspension stem from the way in which it splits the functions for absorbing longitudinal and lateral forces. This permits a high level of lateral rigidity on the one hand for optimum dynamism and driving safety, while offering a great degree of longitudinal flexibility on the other to improve ride comfort.
The shock absorbers deploy a highly innovative technology in the form of Audi magnetic ride, which has already made its mark in the Audi R8 high-performance sports car and in the TT. Here, the conventional shock absorber fluid is replaced by a magneto-rheological fluid whose viscosity can be controlled by means of an electromagnetic field. This effect allows the damping characteristics to be adapted electronically at any time by energising the electromagnets.
Audi magnetic ride capitalises on this quality to make the appropriate damping forces available in any driving situation, thereby optimising both ride comfort and performance dynamics. A computer linked up to a system of sensors interprets the current driving situation with split-second speed. At the same time, drivers are able to choose between two different drive modes, depending on whether they wish to have a distinctly sporty drive Â– with the magneto-rheological fluid at a low viscosity Â– or a more comfort-oriented ride.
