Mileage range at full charge

And at 72 mph to boot! 15% e-power on Green. I’m excited to get some miles under my wheels!

Lol.

When I’m on the interstate I always drop it in green. I’m not going to be zipping around on the highway, and highway miles are the most taxing on range. It doesn’t do much, unless I have the climate going, but hey no sense in burning energy that I don’t need to.

As an fyi, that’s not super typical… it dropped pretty quick once I got a few more miles on the trip. Apparently the last trip I had taken was SUPER docile.

My range typically sits around 95-105mi on the highway.

The range estimation is useless and meaningless.
No matter how many trips I take and with each one exceeding 169 miles of calculated range based on battery percentage it never shifts from 110-127 projected and after longer, slowest more efficient runs the 100% projection often goes down which means it’s not learning from our driving habits.
It seems to me it’s based on a fixed value with a temperature compensation and that’s iir. Which renders it totally useless and a real half-assed effort by BMW/Mini.

Yeah, I think it’s calculated off of the last 5mi of driving, then subtracts off a percentage if the HVAC is on. (If you have the HVAC off in mid mode, then change to green, there will be no change of range).

For around town driving I find the GOM to be reasonably accurate, and if I’m on the highway for a hot bit it’s reasonably accurate, but if I switch from one to the other, the GOM is useless.

My normal is 159km (98.8 miles) on a full charge; the highest I had on a full charge was 181km (112 miles) and my lowest was 135km (83.8 miles). Pretty abysmal GOM compared to all of yours.
 
Got to agree with AndysComputer. The GOM could easily calculate the range based on the current average consumption, and correct for temperature, but it seems to pull a number out of its ...... well if it had one, tailpipe :) Ironically, the best ever GOM readings are always after the worst journeys. The best I ever saw was (from memory) was around 185km after a freeway trip up the coast where I just squeaked home (3%) with a 220km round trip. Luckily the last 1/2 hour was in the city. This is the worst efficiency I have ever had in 2 years, but the next day after charging, I saw 185km. At the next charge, after going almost 250km with battery left, if went back to...... 155km. Really good programming there - I am a programmer and I would be quite embarrassed to put my name to that functionality :)

Ironically, it doesn't even get "0" correct, I have hit zero range with around 5% left. Surely 0 range means you can't move. Really, really poor.

EDIT: I don't make a habit of running the battery down to low percent, however in 2 years I have done it a few times through necessity.

The efficiency shown on the trip computer is also always wrong and off by random amounts (compared to manual % calculation) so maybe it's actually the efficiency person who screwed the GOM dev... Garbage in, garbage out? Or it was the same person lol
 
My car has been getting excellent mileage now that the weather is warm. Yesterday I drove 93 miles. Conditions were 75-80 degrees F. I was driving to keep up with traffic on a freeway with a 65mph to 75mph speed limits for 55 miles. The remaining miles were slower in a traffic jam plus mixed city driving. I have stock 16” Ventura prime tires. I was in mid mode. The battery went from 99% to 34% for a full calculated range of 143 miles. This range is pretty common this summer. I’d be curious to see what green mode would do, but I usually don’t need more range than this.

My average consumption is accurate to the second decimal place with my calculations (distance / battery used). I would be more than happy to use it to calculate the range.

Maybe the internal conversion to mi/kWh is wrong because mine is frequently up to 0.5mi/kWh low... What units are you using? I only get one decimal displayed
 
We gave up on the GOM, instead relying on battery percentage for credible range remaining information. After a few months getting to know the car, battery percentage becomes second nature... if used. No different with gasoline vehicles I guess, many here most likely made educated "guesses" using nothing more than the fuel gauge - 1/4 tank, 1/8 tank and of course the reliable E and fuel light warning.

I never used the GOM on gasoline vehicles, I found them just as unreliable. Most definitely a carry over from legacy.

I haven't checked too many times, but my average consumption yesterday showed 4.8mi/kWh and my calculated was 4.89mi/kWh. I would say that is close enough given that I calculate by rounding to the nearest whole mile and battery percentage.
 
Had my best run today. Never got above 3.8, and that was driving like my dad. But got new tires and took a drive just to see how it goes. Hit 4.4 And yes, I know it's a bit dusty. IMG_20220610_101754775.webp
