New to my X, delivery January 20th and was at the detailer's for full XPEL wrap and glass coating. Coming from Sig S P85, I'm pretty surprised to see high energy consumption of my X in the city (stop and go in Tokyo). Have 20 inch wheels and using sport mode (ludicrous turned off). I wonder if turning off rear A/C makes any difference. In theory it should reduce power usage but do you have any experiences or instrumented test results? Right now I turn it off when driving alone. With family I ask them and turn on if necessary.
