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.
