My MME 4X is my primary vehicle, and I did drive it all winter. I'm riding on Michelin CrossClimate2 235/55R19 tires in both summer and winter, and they have really improved handling in all weather conditions versus the stock tires. I was actually really suprised at how well they handled in the winter, but my MME was predictably controllable and felt extremely capable at all times throughout the winter. Range was down by about 40% which is about par for the course and totally expected.In my neck of the woods the onset of Spring seems to have brought out a lot more BEVs than I seem to remember seeing over the Winter - can't swing a dead cat without hitting a Tesla these days, and a good number of MMEs. So it made me think lots have been hibernating.
So for those of you who live in actual winter conditions - you know who you are - did you brave the winter? And in general how was it?
The only gripe I have is with the way the vehicle seems to very passively maintain battery pack temps. I have been using an OBDII device to monitor stats of the vehicle, and I noticed that the car never tries to warm the pack. I noticed I could be driving around for close to an hour in sub zero temps, and the high voltage battery temp still remains below 0c, which to me seems pretty ridiculous. There is allot of heat generated in the motor assembly that could otherwise be circulated through the pack if those cooling loops are connected. The PTC heater that is used to heat the cabin also never seems to be used to heat the pack unless you are plugged in. The results of this are that when you arrive to a public charger the vehicle starts of charging at about 25KW, and SLOWLY ramps up as the PTC heater is then used to heat the battery (but ONLY if you turn off cabin heating), which again is a pretty sorry ass way to manage pack heating, particularly when cabin and pack coolant loops are connected. So you essentially need to freeze inside in order to get the pack warm enough to charge faster than 30KW, or you use cabin heating and pay extra to sit there charging slowly. My understanding is that this type of charging behavior and battery thermal management might have been improved with the software update available through dealer, but as this is not yet available over the air after 1 year of vehicle ownership, it's still a pretty poor cold weather experience. Since I live in a condo with no access to charging at home, this was a pretty big annoyance for me, and I really wish Ford would get their act together with software, and stop being so slow and conservative with updates.
Beyond the cold weather charging experience, the vehicle was otherwise a great winter vehicle, particularly in terms of it's handling.
