Recently went from a 2020 pre update M3P to a 2022 M3P so likely came from the same car as you. Power tailgate, heated steering wheel, heated wipers, heatpump, laminated glass, dechrome, slightly larger battery, better centre console, Ryzen, lithium low voltage battery, hairpin motor, updated discs and pads, some other minor changes but that is the major ones I can think off. To be honest there is not much difference in the driving, suspension is a bit better over the bumps in town, still not fantastic in town, but very good on an open smooth road. Maybe a small improvement in efficiency in the summer, hopefull a bigger difference will be noticed in the winter. Havn't noticed any big range improvements though even with the slightly bigger battery. Best difference I noticed is the vastly improved wind noise (but this was maybe a problem with my old car more than anything else). I only swapped as I had a great trade in valuation from Tesla, but ended up selling for a decent price to WBAC but thats another story.
