The plug-in hybrid Hummer H3E by Raser Technologies actually gets better mileage than originally estimated.
At the SAE World Congress and again at a Hummer event hosted by California Gov. Arnold Schwarzenegger, Raser originally said (based on a prototype) its E-REV power train could give the Hummer an initial range of 40 miles on electricity only. After that first 40 miles, the SUV would then get about 33 to 35 mpg earning it the dubious moniker of a Hummer that gets over 100 mpg.
Raser's power train is an electric motor-drive system powered by lithium ion batteries, and a gas-powered generator, aka "range extender," to recharge the batteries.
But further street testing has shown the power train's engineers that the H3E could actually get by on its electric battery alone for the first 50 miles using 60 percent of the battery pack, according to statistics released by Raser.
"This initial test indicates that the vehicle should easily achieve over 100 miles per gallon in typical local daily driving," Jim Spellman, Raser's vice president of business development, said in a statement.
Note Spellman's word choice of "typical local daily driving."… Read more
