Raser Unveils 100 MPG Hummer
The demonstration vehicle has been modified using the Extended Range Electric Vehicle (E-REV) power train by Raser and their development partner FEV Inc. The E-REV developed in association with the Plug-in Hybrid Development Consortium. The power train was developed with larger vehicles (trucks and SUVs) in mind, unlike the development of the Volt, which has been focused on cars only.
The vehicle has “performed well in initial test drives and dynamometer testing conducted by FEV”. Video from recent test drives of the 100+mpg H3 is available online: http://rasertech.com/hummer.
The range for the plug-in is about 400 miles, with 40 miles driven exclusively with the battery powered electric motor only. Like GM and their development of the Chevy Volt, the 40 miles of all electric power is the key, since most drivers wouldn’t have to use gas at all on their daily drive. That leads to 100 mpg+ over time.
There is some debate about how to measure fuel economy in plug-ins. Should they be driven on their full range to see what the final number is? Should the tests emphasize the fuel economy at the beginning of the drive, when the battery is fully charged? Or should the car be driven until the battery has been fully drained and the car is driving solely on gas. Should there be a double standard, one for mostly electric drive and one for mostly gas drive?
“We chose the Hummer H3 and H3T as demonstration vehicles because trucks and SUVs are the best-selling vehicles in America and can benefit the most from increased fuel economy and reduced emissions,” said Cook.
The hybrid motor consists of the 200kW advanced AC induction motor connected to a 4WD transmission. A small high efficiency EcoTech engine and a 100KW electric generator is used to recharge the battery pack while driving or to provide additional power when needed.
“Our goal was to demonstrate that electric vehicle technology is a viable solution for a variety of vehicle platforms,” said Gary Rogers, president and chief executive officer of FEV. “This full-sized SUV extended-range electric vehicle shows that fuel economy in larger vehicles does not mean sacrificing power and utility.”
