Self Study Program 480 – Audi A7 Sportback Running gear suspension

VAG SSP 480. A major development goal for the running gear / suspension of the Audi A7 Sportback was to achieve great agility with good control, thus enhancing driving pleasure with high levels of safety and comfort. The use of the proven axle concept with the five-link front axle in connection with a trapezoidal link rear axle is the prerequisite for this. As already implemented in the case of Audi A8 ’10 and Audi A6 ’05, adaptive air suspension (aas) will also be used on the Audi A7 Sportback. This equipment is optional here; the series standard equipment is a steel-sprung running gear / suspension with conventional damping.

From a conceptual perspective, the final drive before differential drive concept used for the first time in the Audi A5 ’08 will also be used in the Audi A7 Sportback, which means a larger wheelbase can be implemented with a small front overhang.

In comparison with the Audi A6 ’05, the wheelbase has been enlarged by 69 mm, the track width on the front axle by 15 mm.

The layout of the steering gear on the subframe in front of the front axle ensures the necessary exact steering response and the precise steering feel in every driving situation.

The electrical implementation of the power-assisted steering has enabled a reduction in the fuel consumption of a max. of 0.3 l / 100 km. Various additional functions can also be implemented.
