While I haven't driven the leg... It seems like the leg from Wichita, KS SC to the Tucumcari, NM SC via Highway 54 is ripe for 1 and ideally 2 SuperChargers (for winter and the S60s). Liberal, KS is 215 miles from the Wichita SC and 208 miles from the Tucumcari SC. 60s would likely be excluded with this route but the 70s and above should be safe. Assuming the base capacity of the M3 is a 70 kWh batter they'd be safe also. Wichita, KS SC -> Tucumcari, NM SC via Highway 54 ~ 422 miles and 6 hours 23 minutes of drive time Wichita, KS SC -> Tucumcari, NM SC via Oklahoma City SC ~ 522 miles and 6 hours 40 minutes of drive time Going this route is a savings of 100 miles and 17 minutes of drive time at posted speeds plus 60+(?) minutes of charge time. Think Tesla would consider adding in 1 - 2 SuperChargers along the Highway 54 route?
