Interesting that the engine is listed as flex-fuel, but the car is not being marketed as such, and we have been specifically told that the car is not E85 capable! Or more likely it is E85 capable, but not certified.
You are right, of course about the rest of the fuel system needing to be compatible. Did the description of the engine for MY 2011 list flex-fuel compatibility? I have a feeling that the entire car is physically and mechanically compatible, but GM is in no hurry to certify the car as 'flex-fuel' because it is still getting so much press. If some 'journalist' drives the car like a bat out of hell on E85 and gets only 22 mpg, you know that would make some headlines with the haters.
