100+ mpg Hummer

It's the monster of commercial vehicles: The Hummer.  And not exactly what you would consider the exemplar of fuel economy.   Yet, the prototype hybrid Hummer H3 gets 100+ mpg demonstrats an unimaginable efficiency for SUVs and offers hope that utility vehicles don't have to be environmental villains.  At its core is the breakthrough Extended-Range Electric Vehicle (R-REV) power-train developed by Raser Technologies of Provo Utah in partnership with FEV Inc. of Auburn Hills, MI.  Unlike other hybrids that switch between electric and gas power, this vehicle is driven entirely on electric power while a highly efficient gas motor recharges the batteries and provides additional electric power as needed. 

* With a battery range of 40 miles, and a total range of 400 miles before refueling, company officials claim that most users drive under 40 miles per day and would therefore never need to refuel. 

* The company's goal is to have this technology employed in a full range of fleet vehicles around the country. 

* The prototype Hummer H3 was unveiled to accolades at the 2009 SAE International World Congress in Detroit, MI.
