John Kargul, EPA's Director of Technology Transfer points... that out this morning in a news article. John Kargul, EPA's Director of Technology Transfer points out that hydraulic hybrids are 70% more efficient than traditional Class 6 trucks compared to less than 25% efficiency increase for electric hybrids during a cycle of acceleration to 35 mph and then braking back to zero mph. Manufacturer of these power trains, Eaton Corporation, believes that they are well suited to inner-city delivery or garbage collection trucks where vehicles are frequently starting and stopping. 50% fuel savings are available, according to the EPA. By contrast, Fiat Group, a leader in agricultural and earthmoving vehicles under the New Holland and other banners, is energetically developing electric power trains. http://www.nanotech-now.com/news.cgi?story_id=40519
