FlexFuel is a "bridge technology" easing the path to a fuel that is not widely available.

It has a bigger problem in the US due to widely varying temperatures. I doubt E100 would ever fly in the US because of cold-weather starting difficulties. Low Reid vapor pressure and all that.

I've been looking at a FlexFuel setup flexing E85 and CNG. CNG requires "driveway fuel" to warm up the cooling system to keep the NG regulator from freezing.

An optimized CNG vehcle would run 13:5 compression with lots of spark advance.

E85 runs 95-102 octane, so it would be OK warm-up and purge fuel for a CNG car. 92 octane PUG is iffy, and requires a big spark retardation to serve.
