E-Flex vehicle line executive Tony Posawatz with the fuel cell E-Flex

Following up on the plan they laid out when they revealed the Chevy Volt at the Detroit Auto Show, General Motors has unveiled the second major iteration of the E-Flex platform at the Shanghai Motor Show. The whole premise of E-Flex was to have a plug-in electrically driven vehicle that could accommodate different auxiliary power units for extending the range. E-Flex version two replaces the flex-fuel gas/E85 engine with the latest generation of GM's internally developed fuel cell technology. All the details on the new concept are over at AutoblogGreen.

      I still DON'T UNDERSTAND why a car with just a battery seems like such a bad idea to people.

      If they made an electric car with a solid 200 mile range that is all 50% of America would need. Just plug it in at your house every night.

      People give the, "but it might run out of charge" argument...but if you actually logged your daily miles I bet the number of days 50% of Americans drove more than 200 miles per day in a year you could count on one hand...

      AMERICANS ARE JUST AFRAID TO BE TIED DOWN, that is the problem.

      It is wonderful that GM has remembered the value of being the industry leader in technology. This new 5th generation Fuel Cell system at half the size of the 4th generation with the same power and twice the efficiency the E-flex is simply amazing, a engineering marvel to advance technology so quickly.

      1. That is way cool. All they need now is to trim some of the production costs down a bit and they are on a winner.

      And maybe some smaller wheels...

      pipe dream... why.. just because they're not actually leasing fuel cell cars like their competitors, or because that damn fuel cell sled made zero advances for so long, come on :P

      F China and F GM.

      GM could care less about this space. This is just FLUFF.

      Oh, and they also need to set up a hydrogen infrastructure that doesn't produce its hydrogen from oil...

      Dave, I disagree about A/C, defrost. I leased an EV-1. It used a heat pump for HVAC and electrically heated windshield for defrost. Depending on vehicle weight a 200 mile battery would be about 25KW/Hr. Expensive, yes, but I'd wager one big battery is much less expensive than a platinum coated FC plus dual 10,000 psi carbon fiber tanks, plus 8KW/Hr battery. Advancing battery and recharging tech is much simpler than pushing the fuel cell and hydrogen approach. Plus you don't need to build an entire hydrogen infrastructure from scratch.

      It's a pipe dream.

      Also, why is that guy wearing an ABC Sports jacket from 1981?

      #9 I know I'd be happy with an electric car with a 50 mile range. The only caviat is that it needs to be able to do that at 90 mph since people will run you off the road if you're going any slower on a Texas highway.

      Definitely think GM is on the right path with E-Flex. Making a platform that can support different fuel systems sounds like the right way to get alternative fuel vehicles mass produced at affordable costs.

      Like Hydrogen as a fuel or not, it is going to be in the mix and is likely to play a large roll in the future of automotive transport.

      Bio fuels and hydrogen offer the range that batteries currently can't and many people will not be willing to give up 50%+ of their vehicles range just to drive green so they'll choose either bio-fuels or hydrogen.

      Now, throw that 8Kg Hydrogen tank from the sequel in that instead of the 4Kg tank they have in there, boosting the range to over 1000 miles per tank and people will really rally behind it.
