So, BEV pilgrims. After rolling nearly 50K (47,750) to be exact). I thought to share a Dec '24 through July '25 data graph. We've been a 2 BEV household (racking up a total of 110,000 miles between the ER Lightning Lariat and the SR Mach E) going on 5+ years now and I've pretty good idea of how to read %, KWH, mile range, etc. In an 88-mile daily commute of which the graph basically represents I roll at as below. I've a few longer tips up to the college so that adds about 72 miles once a month or so. A few local trips.
30 mph or less = 8 miles
~40-45 mph = 18 miles
~53-57 mph = 22 miles
TOTAL = 88 miles per day and averaging right 80 mpge.., Crazy.
I tend to drive the winding modest hilling, rural state route at 44 miles in 56-60 minutes, so an average of around 43-45 miles an hour. My best ever was 37 minutes, and I was hauling ass. The Sheriff asked me one day why I was "going so slow" and I said, well having a stater pick me up is no fun", besides I don't have lights and a siren. This is all not true of course but I give as an example of what could happen. But I'm a good Eagle Scout and I'd never pass 5 slow cars at 90 mph because of torque multiplication. No way.
That mileage includes brutal winter storms out of the SW and headwinds at 15-20 mph as well as brisk summer NW winds which give an efficient ride home. A few sub 30 F days, a lot of 38--42F days and then the weird Pineapple Express (55 F+ and pouring rain, sheet flow water on roads). As well as summer traffic, road work, brake for trees, animals, small roadside slumps, etc.
Your KWH average is basically a weighted average of all speeds and thus isn't an immediate measure of energy. The range estimate tends to be slightly less than the real distance traveled, and summery data tends to be in whole numbers and not xx.x fractions. I've played around with other GPS map distance aps, and I think the distance tends to be off on my drive at maybe? one (1) mile under. What does this mean? not much in the big picture.
Take homes. Best mileage was bald Hanooks. I think... barely. About 35% bald across the lateral profile
. The Michelin's were a bit rough the first few thousand miles. Best mileage in the stratosphere for a daily driver at 2.6-2.7 because 68-78 degrees F and NO WIND (no can't drive 55). I can drive 3 over and get away with it as the local WPS Sergeant says... "Don't let me catch you at 59 and I might think about 58 if you're messing with me". I tend to play nice.
The range estimate, kWh estimate, % estimate is sensitive to change imparted by the above-mentioned speed, temp, wind, as well as tire pressure, worn tires, etc. etc. like load, towing, etc. etc. susceptible to change, a lot more than the air flow and fuel meters of ICE which are quite lousy at good energy estimates. Best of all I use typically 32-40 kWh per day and that works to an insane $2.10 to $2.56 per day to drive 88 miles RT. Our power is about $.064 per kWh.
Have fun scouring the chart, tell me if you see errors. Love the truck.

dove it like a baybaby for the next 25 K but dang near wrapped it into tree on a frozen bridge deck. Off with the Hanooks head and on with Michelins!
