If I'm driving 298 WH/Miles since the last charge, I believe this is very NORMAL driving
. AC on
. Radio on
. (300 to 350)WH/Mile driving habit
I would say this is all normal driving.
Regardless of EPA reports or whatever... as a Tesla owner, I would much more appreciate a transparent reporting of HOW MANY MILES I CAN REALLY DRIVE.
With all due respect, I call BS on anyone who says they are getting MORE than the stated miles available... I just don't see it (and please share your magic with us).
If I see on my odometer (150 Miles available). I would like to know that I can "reasonably" get 150 miles, not 120 to 130.
Tesla should underestimate the miles available rather than over estimate. (since chargers are not available on every other street corner)
At this point, they are OVERESTIMATING...
I'm not a hyper miler. I weave in and out of traffic on the highway far more than I should which adds in accelerations and decelerations I wouldn't have if I didn't do that. I make some people nervous when they ride with me. I'm also not doing a bunch of hard accelerations. You may very well drive more spirited than I do. My car is currently averaging overall 297 wh/mi for the 7500 miles I've been driving it which includes the tail end of an Ohio winter and in recent months based on teslafi I am doing much better. I've included my July teslafi.com summary below. I'm averaging 273 wh/mi for the month so far. Most of the longer drives (> 25 miles) run below that average. Teslafi uses the ratio of actual miles vs rated miles to compute their "efficiency" number. It's interesting because even though the car is reportedly rated for ~290 it looks like you can to average about 265 to get 100% efficient per teslafi. That number varies a little bit, between 263-268 wh/mi based on my calculations.
I also pasted in a summary from one drive so you can see how it uses the rated miles consumed vs. actual miles. The variation between rated miles and efficiency is part of why I don't use the miles setting for my battery status on the car. I set it for percentage and then I look at the center screen efficiency number to get a sense for how I'm doing. I also keep in mind a general conservative rule of thumb of 2.5 miles of range per 1% of my 75D's battery (that works out to about 300 wh/mi - 1% is 0.75 kwH divided by 2.5 = 300). In the winter I go with 2 miles of range per 1% which works out to 375 wh/mi which is what you'd see on a pretty cold day. For longer trips I also run them through evto-tesla on my iphone and it's usually pretty darn close to right and it accounts for temperature, altitude change, etc.
I have a 2016 S75D with 19" wheels. The wheels make a big difference too.
So I guess you might call BS on me since sometimes I get more than the rated miles and I often get more than the rated wh/mi and I'm almost always beating the EPA estimated wh/mi (340 - see link below).
I am curious if anyone out there can explain why the difference between those two concepts and then also why the EPA site says that they got 340 wh/mi with my car so why are the rated miles working out to 260's.
