I just drove my 2022 TM3 RWD 2032 miles to our winter home in Portal AZ. We averaged 267wh/mile over the entire 4 day trip with ~90% being freeway driving, mostly at over 75mph. we had about 17 DCFC charging stops including 5 at EA DCFCs and the rest at Superchargers. Charging at EA was problematic and we never found a fully working 350kw charger. The only one we got to work only gave a 30kwh charge rate. The 150kw chargers worked ok. The EA station at the Benson AZ Walmart was our last DCFC of the trip: It was a 150 KW charger and we charged to 100% whilst shopping (just as well as the Grid went down 4 hours after we arrived at our house) for groceries - the LFP M3 charges incredibly fast especially at a high SOC. TSCs were flawless and we hit a peak 171 kw charge rate at several of the V3 SCs. One hotel gave us a free L2 charge, but another (Best Western Plus Foothills Yuma AZ) tried to charge us $25!, or about $1/kw, I said no thanks.
