A hybrid wheel loader from Volvo Construction Equipment has posted a 50% gain in fuel efficiency. The (Source: Volvo Construction Equipment)(Source: Volvo Construction Equipment)prototype had been operated and tested at a California landfill by Waste Management Inc.

The LX1 series hybrid incorporates a driveline that consists of electric drive motors mounted at the wheels, electric-driven hydraulics, a battery energy storage system, a significantly smaller diesel engine (3-liter vs. 13-liter) and new machine architecture. The engine used 100% renewable diesel, resulting in reduced greenhouse gas emissions, supplied by Golden Gate Petroleum.

This advanced technology development and testing program was funded by the California Energy Commission's Alternative and Renewable Fuel and Vehicle Technology Program. CALSTART, a non-profit clean transportation technology industry organization, conducted independent testing of the prototype and confirmed the 50% improvement in fuel efficiency on average.
