The EPA rating of the M3 AWD is 116 which is 290W/mile, that translates into a 90KWh battery for 310 miles of range. Everything I've read says that the M3 battery is only 75KWh. To get 310 miles out of a 75KWh battery the you would need to get 241W/Mile which is an MPGe of 139 (33700/241), that's not unrealistic I'm doing better than that I'm getting 224W/Mile which is an MPGe of 150. So which is it, is the EPA rating way low or is the battery really 90KWh not 70KWh?
