Actually, engines that run only on E85 can get higher efficiency than gasoline engines, but this requires they run at higher temperatures, requiring higher compression, temperatures that cause gasoline to pre-ignite.
Flex fuel is the adaptation that was done in places like Brazil to enable a quick change over to E85, but instead of retrofitting, its installed at the factory.
It is a cheap bridge to a market with E85 being readily available in the market. Like the transition from leaded to unleaded gasoline.
E85 isn't more available because some vehicle fleets are actually tuned to E85 and the fleet owner has its own E85 fueling stations which are restricted to its fleet.
The ability to expand the availability of E85 is in part limited by the oil companies not being willing to defend "the perfectly safe MTBE" oxygenator, and thus switching to ethanol as their oxgenate additive.
