2018 Ford C-Max Hybrid - Mileage

I have a Ford C-Max with which I am completely satisfied. One question though. Do Hybrids get better mileage in warmer ambient temperatures than colder ones. My miles per gallon went down when the weather got colder and now that it is warmer it is going back up. If this is so, why? If not what else could cause the decrease and then increase in MPG. The driving habits did not change.

All cars mileage drop in the winter, a cold engine needs a lot more fuel to run than a warm engine and a hybrid will have less range because battery power drops with the temperature.

Yep, the friction is higher and the engine has to run more to warm itself and you. Spring and fall are the best, mpgs drop a bit in summer because of a/c loads.
