    With Xs hitting the road, any comments from existing owners on how it compares to Model S?

    I was pondering the same question, particularly what is *rated* Wh/mile as compared to MS rated Wh/mile (300 Wh/mile).

    Actually, different Model S have different rated Wh/mile. My Model S 60 was 287 Wh/mile (IIRC), the P85D is 304 from what I can tell.

    Yes, of course you are right, I was talking about my car (P85+ - without actually mentioning it :smile:). Hopefully some of the new MX owners can chime in.

    I finally was able to make a "normal" trip. Tires broken in, weather mild, elevation changes minor and urban freeway speeds 60 to 70 mph on first leg and slower return, in heavy traffic at 45 to 65 mph. Here are the charts.

    The trip B total miles are almost all higher speed (75 to 85 mph) and low temp miles. The trip A was today's 90 mile normal urban round trip. Mostly freeway but not high speeds.

    Energy chart with rated miles line displayed. This segment was rush hour freeway with lower speeds (40 to 50 mph).

    I drive pretty normal and dont worry much about trying to get better Wh/mi numbers. I just drive and don't use the brakes very much. No effort to maximize efficiency.

    Thanks Roamer.. I've been wondering about that since most people have been posting 400+. I assumed it was mostly due to new tires, playing with the performance, etc and yours confirms that the X can get quite close to the S in Wh/mi.

    Thank you for the pictures, Roamer!

    After scaling the "rated" line from the energy app, it appears that Model X rated energy consumption is 335 Wh/mile.

    Over the first 980 miles of mostly 2-lane under 60 driving but about 20% freeway at 60-75 mph, I'm averaging 334 Wh/mi in my P90D.

    Sounds respectable with no range anxiety....
