Burns continued by saying the Chevy Volt might only be available in five U.S. cities at launch.
But the outlook for a European E-flex vehicle -- likely in the form of the Opel Flextreme -- is even bleaker. Industry analysts say that the Opel variant wouldn't bow until 2013, despite GM's claim that Europe is "a very important market for this technology."
Burns compared the Volt's slow development to that of the company's 12 year old OnStar system, citing lithium-ion battery technology as the biggest hurdle. "Today's generation of OnStar costs radically less than the 1st generation and is dramatically more capable," he said. "That's what we've have to do with this plug-in electric technology."
As for that 2010 launch date? "It's a challenge," Burns says.
