Audi Q7 e-tron quattro 4M - Chassis System of the Audi Q7 e-tron; Chassis Overall Concept

66
The AudiQ7e-tronquattro adopts key chassis components from
the AudiQ7(type4M). There are however several minor dierences
due to functional requirements (electric drive, blended braking
etc.) and the modified package (location of hybrid battery).
On account of the dierences in axle load compared with
AudiQ7(type4M) and the modified axle load distribution, the
Overall concept
chassis systems have been reconfigured using special springs,
dampers and anti-roll bars. All-wheel steering will not be available
for the AudiQ7e-tronquattro at launch. The chassis alignment
and setup procedures are identical to those for the
AudiQ7(type4M).
