I've not measured my overall mpg, so can't help there, but I get the burning smell as well. I've heard, on internet, it's something to do with some sort of coating on parts of the car that smells like that when it heats up.
One thing I have noticed just in the last week is how much the cold weather reduces the battery range. I've gone from about 26 mile range to about 19 from a full charge and that's without adding any extra load such as heating, lights, a/c etc. I gather this is normal.
The only drawback, for me, is that's it's completely changed my driving and now I want to go full EV.
Cheers
