Freightliner Custom Chassis Corporation (FCCC) has introduced a pilot hydraulic hybrid walk-in van chassis. Designed and engineered in partnership with Parker Hannifin Corporation, the pilot hydraulic hybrid chassis is on display in Chicago at The Work Truck Show’s Hybrid Pavilion.

Based on the MT-55 walk-in van chassis, the system uses a series hybrid configuration, with the combustion engine connected to an engine pump motor.
Preliminary testing have indicates that the hydraulic hybrid improves fuel economy between 50 to 70% over traditional diesel-powered vehicles with automatic transmissions in stop-and-go applications. The hydraulic hybrid improves fuel economy in three significant ways: recovered braking energy; improved engine efficiency; and its engine-off feature.
