Levant Power's energy-producing GenShock suspension has been stuck in limbo for a while, but the company has just announced a deal that could finally put the technology in passenger cars. Automotive component firm ZF has agreed to help develop a GenShock-based active suspension that will both convert road bumps to electricity and smooth out its host vehicle's ride. The system will theoretically offer the comfort of a luxury sedan, the power efficiency of a hybrid and the nimble handling of a sports car. It might even simplify repairs -- since GenShock recovers energy through pumps, it can raise each wheel without needing a jack. ZF doesn't yet know when we'll be driving cars with the new suspension, but the technology is reportedly inexpensive enough that buyers won't require a supercar-level budget.
