We applaud GM for having the foresight to not only invest in hybrid and electric powertrains, but also to develop the E-Flex system, which could accommodate multiple fuel sources, such as bio-diesel and hydrogen. We’re not crazy about a 40-mile range, or 400 pounds of curb weight dedicated to the lithium-ion battery, but those figures would likely improve before anyone mentioned production, which is more than a few years out. We’re betting that unless the range is extended, the masses may be quick to praise but slow to pay for the E-Flex technology because whether it’s real or perceived, “40-mile range” would likely lead people to wonder if they’ll be left stranded when the odometer clicks over to 41.
