New X owner of a 2018 P100D with 22 inch wheel/tires. Have a trip (Literally Tomorrow) that is 115 miles one way that I am going just for a client meeting. My initial assumption was that my 287 miles that displayed on the dial would be pretty close if I drove the speed limit, giving me a slight buffer. I’m reading a TON of different amount of disparity between the mileage showing vs. actual driven online. What are you truly seeing? There is a supercharger for emergency that would add about an 50 minutes to my trip, but I really really am hoping that even in chill mode, with good weather, during the day with mild wind I will be able to get a true 230 miles. Am I a nut for thinking this should be a possibility?
