How's this for a new suspension system:

Inset: Bose’s invention uses a linear electromagnetic motor to push and pull the wheel in and out of a dip without jostling the car body.

"Supplanting almost 100 years of traditional spring-and-shock-absorber suspension systems, this new system from Bose—a company best known for its stereo speakers—uses electromagnetic motors in place of traditional shocks. Mounted on each wheel, the motors use input from sensors throughout the  vehicle to react to bumps and potholes instantaneously, exerting downward force to extend the wheel into potholes while keeping the car level and you comfy. As the wheel pops back up onto the road, the suspension recaptures nearly all the energy expended; it uses only one third the amount of power your AC does. And beyond smoothing out bumpy roads, the system improves handling, virtually eliminating body roll in tight turns and minimizing pitching motion during braking and acceleration."
