The front suspension is of the McPherson type,

The suspension on either side consists of: spring strut, control arm and anti-roll bar system.

Spring strut 

The spring strut consists of shock absorber (21), spring strut bearing (3) with auxiliary spring (5), boot (6), spring (1), upper and lower spring isolators (7), upper bearing (2), stub axle (11) and wheel bearing (12).

Anti-roll bar system 

The anti-roll bar system consists of anti-roll bar (16), clamps (15), anti-roll bar bushings (17) and anti-roll bar links (8). Versions with a V8 engine have a uniquely designed anti-roll bar.

The shock absorber 

The shock absorber is integrated in the spring strut.

The shock absorber's piston rod, in the upper section, is screwed to the upper bearing (2) and in the lower end, screwed to the stub axle (11). The spring (1) is supported against the upper bearing (2) via the spring strut bearing (3). On the underneath of the spring strut bearing (3) there is an auxiliary spring (5) and a boot (6) for the shock absorber's piston rod.

The spring is isolated by upper and lower rubber isolators (4).

There are two versions of standard shock absorber depending on the weight of the vehicle:

Four-C (Continuously Controlled Chassis Concept) has a comfort, advanced or sport setting.

Control arm 

The control arm (19) is attached to the subframe (10) by the front bushing (13) and the rear bushing (14).

Subframe 

The subframe (10) is made of steel.

The front and rear bushings (9, 18) are installed with a press joint. Versions with a V8 engine have a unique subframe due to the engine mounting.
