Out of interest, how does Tesla calculate 15,000 miles of supercharging? surley it would be easier to give you "5,000kwh?" as its all subjective on how efficient the car is? do they calculate it on the rated range of the car or the actual real world range?
The M3P has a WLTP of 328 miles, which realistically is circa 290-300 miles.
FWIW, a friend of the SO's and mine bought a MY earlier this year on a referral, meaning that we got referral points. In the U.S., anyway, this lets one convert the points into various kinds of swag, be it those little trays in the arm rests, enhanced connectivity, various articles of clothing, and so on.
One of the several things we got with the points was 400 miles of free supercharging on our account which, interestingly, has two cars on it: A 2021 MY and a 2023 M3. We've taken several trips on both cars and, no kidding, got the free Supercharging on both. I managed to run the account dry on Sunday
, and so had to pay $2.03 for the tail end of a Supercharging session in Connecticut.
In the U.S., there's this sticker that comes with all new cars called the Mulroney sticker, named after the Congressperson who, back in the day, wanted consumers to Know What They Were Getting. Of the many things on that sticker, there's the EPA rated efficiency of the car. The MY's sticker had 270 W-hr/mile; the M3's is 260 W-hr/mile.
I've always assumed that the amount deducted from the 400 free miles was Miles_Deducted = (Energy_Used)/(Rated Energy/mile), and that was dependent upon the car.
The WLTP you put up is the range; fine, as far as that goes. What's the WLTP number for the Energy_Use per Distance Traveled? I presume it's in W-hr/km or something.
