how much extra do they charge for different injectors, a yellow gas cap, different ecm calibration, and a "flex fuel" badge for the exterior?
if GM had half a brain, they'd make a few cars with an "E85 ONLY" option consisting of 12:1 static compression ratio and bigger injectors.
seems to me that the Solstice/Skye with the turbocharged, direct injected Ecotec would be a natural for an E85 compatible car, too.
