Tests of Hybrid Utility Trucks Show 40%—60% Fuel Saving

Initial tests of diesel-hybrid utility trucks indicate that they may have a 40%-60% reduction in fuel. Apparently utility trucks get better fuel reduction than passenger cars because they have massive batteries on board. The tests were performed on prototype hybrid utility trucks being used in the WestStart’s Hybrid Truck Users Forum (HTUF) pilot program. The target requirement for the hybrids was a 50% reduction in fuel consumption. The drive system in the utility trucks is in a pre-transmission parallel hybrid configuration, with a 44-kW permanent magnet motor mounted directly in front of the transmission, behind engine and clutch. Li-ion batteries provide the energy store. :: Via Green Car Congress
