Indiana-based Bright Automotive today unveiled the IDEA, a 100-mpg plug-in hybrid cargo van intended to significantly reduce fuel consumption for the largest vehicle fleets in the U.S.

As a plug-in hybrid, the IDEA can drive for the first 30 miles using electricity before switching into a standard hybrid mode. The 100 mpg rating is an estimate based on a typical 50-mile daily urban route, which would use only 1/2 gallon of gasoline. Of course, as mileage increases the mpg rating drops, but not too badly: a 70-mile daily route would still only use 1 gallon of gas, or 70 mpg.

Meanwhile, Raser Technologies this week looks to revive the Hummer H3 by developing a Range-Extended Electric Vehicle (ReEV) prototype version. The vehicle is designed, first and foremost, as a purely electric vehicle with a drive train similar to the Voltec system in the Chevrolet Volt.
