Hybrids step forward

Electric and hydraulic systems trim fuel consumption and emissions, boost performance.

Passenger vehicle buyers haven't widely embraced the hybrid vehicle concept, but many suppliers feel off-highway owners will find much to like with hybrids. Many vendors are unveiling hybrids that use either hydraulic or electric power to reduce fuel consumption and emissions while also improving performance.

Activity in hybrids is picking up. Earlier this year, Ricardo announced that it is setting up a dedicated team of electric machine, power electronics, and control systems specialists whose goal is to help design teams develop state-of-the-art electric powertrain systems. And Eaton said it has shipped more than 6500 hybrid vehicle systems.
