The 500 has a McPherson strut front suspension and a torsion beam rear axle.
Notable on the front suspension is the way the anti roll bar end link is attached to the strut with ball jointed sockets. This type of end link is usually reserved to high end cars and boasts a greater ability to filter out vibrations when driving over rough roads.
Also featured in the front suspension are:
New designed coil springs designed to increase the absorption of minor surface roughness
Newly designed control arm bushings that improve ride and handling
A suspension subframe that is attached to the body of the car without the use of rubber isolators
In the rear, the compact, torsion beam axle functions both as wheel locating arm and as an anti-roll bar to resist lateral motion of the wheels as the body leans in turns.
Other characteristics of the rear suspension are:
Greater comfort because the level of noise and vibration entering the passenger compartment is lower due to single (metal and rubber) bushings attaching the rear axle to the body
An optimized underfloor shock absorber angle that locates the shock beneath the floor to improve comfort without detracting from trunk space
Greater driving stability due to the bushings attaching the rear axle to the body. While cornering, they generate a wheel toe-in effect that ensures excellent driving stability even under difficult conditions. They also display great longitudinal flexibility when hitting bumps.
Handling is improved because the folded sheet steel torsion beams torsional rigidity has been tuned to provide balance between front and rear.
