You should already have an idea of how much battery you'd consume for the routes that you drive often, even long ones. If it's hundreds of miles, where you need to charge in between, or the consumption will vary significantly enough due to wind speed, then it just seems prudent to use the NAV to get that % remaining on arrival estimate.DougWantsALeaf wrote: ↑Sat Aug 10, 2019 2:15 pmAll this assumes that you are constantly putting your destination into the computer.
Personally, While I use the GPS on on occasion, wont use it for most common routes, even ones hundreds of miles, and find the Leaf gom pretty good, way better than the 2013 gom.
It’s funny (again I really like Tesla cars and was outvoted to get one) is that the is one gripe my colleagues have is that don’t like the Tesla range system. They refer to the range shown as electric miles and that its takes more then one electric mile to do a real mile in their X and 3.
I don’t have enough time time in a Tesla to comment, but found the commentary interestingness contrary to this thread. The videos showing % remaining on arrival look pretty impressive.
Interesting. I have found the rated range to be dead on for my 2013 model S85. I typically drive 69 MPH on the freeway. If I start a long drive with 200 miles of rated range (80% charge for me) and drive 120 miles the rated range left is usually close to 80 miles. This is true even when I drive from 240 feet elevation up to 4100 feet elevation in the mountains and back again to my house. As long as I am doing a round trip the rated range is a very close approximation for me. Yesterday I started with 222 miles of rated range, drove 130 miles including up to 6100 feet in the mountains and back to home at 240 feet elevation. I ended up with 84 miles of rated range so at total of 214 miles (84+130) were accounted for. Probably was a little less than the 222 miles due to having 3 people in the car with our day packs and climbing over 5000 feet (we did get quite a bit back on the way down, of course). I think that is damn good. No complaints here. All depends on how your drive.DougWantsALeaf wrote: ↑Sat Aug 10, 2019 2:15 pmIt’s funny (again I really like Tesla cars and was outvoted to get one) is that the is one gripe my colleagues have is that don’t like the Tesla range system.

The Tesla doesn't have a guess-o-meter (gom). The rated range is if you drive 65-70 MPH and don't hot rod around at slower speeds. The advantage of rated range is that it lets you know how/if the capacity of your battery pack is changing. It might be useful for some owners if Tesla also had a "My range" where you could put in your highway speed and get a more accurate estimate. How far off do the owners say the range is from the rated range when they drive 80 MPH? Air resistance would be about 30% more at 80 MPH.
What you, or your colleagues, are miscalling the "gom" is just a fuel gauge. If it is confusing to have a fuel gauge displaying "electric miles" they should just switch it to %SoC and leave it that way. Navigation, however, DOES adjust down — or up — for driving style (as well as weather and the like). That's what should be used if the range is limiting on a long trip. [As it happens, over the last 73,000 miles my actual miles have been substantially higher than the rated miles (meaning that I drive at better than the EPA rated efficiency for my car); this is quite common in the Tesla community but it does depend on driving style and where one lives.]
Tell them to use the estimated destination SoC. It adjusts for driving speed and road/weather conditions.
