You would figure the engine wouldn't run so rich while cold (30 degrees F) - (more fuel = lower combustion temperatures). Only drive one or two miles in ERDTT (for about 5 minutes) but, what a hit to MPG.
I'm thinking the gas "guess-O-meter" may be off and needs to recalibrate.
No that is pretty much standard. The gas and elec runtogether during erdtt though so your mpg will be 40-50 or 60 that depends.....I guess you could hold mode and go to all gas but then your overall mpg would be in the 30's
