GM already working on second E-Flex vehicle for Opel (and Saturn?)

Following his speech to the Commonwealth Club a few days ago, GM CEO Rick Wagoner apparently told reporters that a second E-Flex platform vehicle was also under development at the company's Warren MI technical center alongside the Chevy Volt. This second ER-EV is destined for the Opel (and presumably Saturn) brand. Following the debut of the Volt in January 2007, GM has shown two other E-Flex concepts, the Opel/Saturn Flextreme and the Cadillac Provoq. The Provoq is expected to make the production transition in 2009 as a conventionally-powered crossover. The Flextreme, however, carries some of the design language of the new Opel Insignia that was recently revealed. The significantly more aerodynamic Flextreme also carries the hatchback/wagon type body shape that is more popular in Europe. An Opel-badged model would likely have an appearance similar to the Flextreme but with more conventional style body openings and without the pair of Segways in the back. It's unknown at this point what type of range extender would be used with the Opel although the concept used a diesel. So far we've only found one source for this report of a second E-Flex vehicle and we're still waiting to hear back from GM for any confirmation or comments on any of this. As soon as we here back we'll provide updates.
