I've had my Tesla Model 3 Performance for exactly 1 week now, and have driven round trip to my office a minimum of 6 times now (or 12 travel attempts at 22 miles per travel attempt). In doing so, I've used it to test various travel distance numbers, and tried adapting driving habits to change those numbers.
My office is 22 miles from my house. One direction has a little bit more downhill than the other direction, but outside of a single steep hill that I go up and down (about a 25% grade at 25mph up and down, 300' each direction or so), most of it is only about a 5% grade one way or the other.
I've found that two of my single direction trips were 11% battery usage (one of which, I had the AC on. All other trips, it was off), and a single one way trip was 9% (I believe it was right on the edge of turning into 10%). All other trips were consistently 10% battery usage each way. By that math, the vehicle has a total range of 220 miles on a 100% to 0% charge, or 22 miles per 10%. I've tried driving aggressive, and I've also tried driving like a grandma, constantly watching my acceleration, trying not to peak over 20% of the black bar underneath the speedometer, and when going downhill, trying to maintain my speed while running in the green. Neither one has made a difference on this trip.
If I change my battery percentage to miles to empty however, it consistently reads that I get 30 miles per 10%, or 300 miles should I be charged to 100%. Today I was down to 30% (I haven't yet gotten my 220 outlet installed, so have been stuck charging at 110 and it's just not cutting it), and it stated I had 90 miles left when I switched to mile range rather than battery percentage. I know that in truth, if I'm lucky, I can go 66 miles in 30% battery, not 90. That's a pretty substantial difference!
So the first question is: Is the conversion from battery percentage to expected miles to dead battery, based on actual average driving, or is it based on the best possible outcome, and completely ignores your driving style?
Second, have you found that autopilot uses more power than manual drive, the same, or less? From what I've visibly experienced, it brakes and accelerates a lot more frequent than manual drive, which leads me to believe that it's not as efficient as manual driving.
Third, for those of you who have a Performance Model 3, what should I actually expect to get out of the vehicle in terms of range? Do you find you get better mileage on city streets or freeways? If you hold a consistent speed on the freeways, does it make much of a difference to stop and go on city streets? Also, have you noticed, is traveling at 80mph instead of 65 mph more or less efficient? I know there is a tipping point with ICE vehicles where the gear ratio combined with drag of the vehicle causes the vehicle to kill more gas than if you traveled slower for a longer period of time. Where have you found that sweet spot lays with Tesla?
Lastly, do you find that fast acceleration and then maintaining a higher speed is more battery efficient than slowly accelerating up to speed (lets say 65mph for reference), and then maintaining speed is more efficient? In the fast acceleration, technically, you'd only need to burst draw power for 4 seconds or so to be at 65mph, then drop off the accelerator and cruise. Is that not more efficient than drawing on the battery harder for 20 seconds to slowly get up to 65, but not peak it out?
Would love some insight!
