Hybrids Go Hydraulic.

The U.S. Environmental Protection Agency and a host of corporate partners have demonstrated the first advanced hydraulic hybrid sport utility vehicle. The vehicle demonstrates that hydraulic hybrid technology has the potential to dramatically and cost-effectively improve the fuel economy of SUVs, and at the same time, improve their performance, according to the EPA. The hydraulic system captures and stores a large fraction of the energy normally wasted in vehicle braking and uses this energy to help propel the vehicle during its next acceleration.
