^ Yup. If an engine is built to run E85 only, and not E0 or E10, it will have higher compression and advanced timing, and therefore be more efficient at extracting energy from the fuel, leading to only a small mpg drop compared to an engine tuned optimally for gas.
Call me crazy, but I actually try for mpg with this Jeep:

Typical driving: Back in Rochester for school, driving is 60 - 70% city
