Yesterday was my first "summer" run, where the weather was warm enough all day for efficient operation. I didn't set out to go that far, but this was a regular day for me. Not as impressive as @Rexsio but I spent much of the time on the freeway so I think it's pretty good. And way above the official range of 110 miles (I had 30% SoC left). MiniRange app computed total range would have been 152 miles (5.26 mi/kWh).

I like to see pictures in that configuration like Puppethead show on his dashboard with biggest number possible all theoretical mathematical or percentage configurations is not acceptable a picture with those 2 arrows and milage is only proof of distance you travel starting 100% battery IMG_1494.webp IMG_1493.webp second picture with arrows is Rexsio milage

Additional evidence clear your 161 miles and I believe you are only a ONE to be hard to pass bc nobody is close to this accomplishment.I don’t mean to upset you just try to keep this legitimate Rexsio .Thanks for response with additional data .

No worries - all in good fun.

Since I only charge at level 1, I had planned to use my other car today so that my SE's battery could "catch up" to my regular use. However, I'm already up to 46% (so close to 4% per hour, versus the usual 3%). So, more joy awaits!
 
There's a YouTube video of a gentleman who averaged 30mph on the back roads in Britain who got around 170 miles. One odd thing that he did was not to use maximum regen, but the lesser regen. He was getting 5.8 m/kWh. Best I've ever seen was 5.2.
 
It's summertime and I'm easily getting over 5 mi/kWh without even trying. Here's a particularly good day from last Friday's commute.

***********************************
Jun 14, 2024 at 18:01 ** 78°F ** Wind: 4.169 mph from NE ** Humidity: 44% ** Driven: 87 Mi ** Start-Batt: 100% ** End-Batt: 45% ** Mi / kWh: 5.47 ** GOM Reading: 48 Mi ** Range Left: 71.14 Mi ** Total Range (From 100% charge): 158.14 Mi ** Total Range (From 100% charge): 158.083 Mi

I thought it was a stretch for Lucid to claim they're the only ones getting 5 mi/kWh. Unless they're going by "official" rating. I should be breaking 6 mi/kWh in my SE if the rain ever stops.
 
Since it was hot and I knew that I was going to be pushing the limits on Monday, I drove a bit more conservatively on the way to/from work. I don't recall what the center display read when I got home, but it reported 6.9 mi/kWh for the trip in (which is a few hundred feet downhill over 13.5 mi). That's better than normal, but in warmer weather I am routinely above 6.

Here's the rub, though: that trip used 10% of the battery, and 13.5/(28.9 x 0.10) = 4.7 mi/kWh.

IOW, as pessimistic as the GOM is about range, the efficiency numbers reported by the car are overly optimistic. However, I also don't think that going by % of battery is perfectly accurate either (although it is clearly better), as there seem be some non-linearities/anomalies there as well.

To paraphrase the wise old owl, how far can an F56 SE go on a single charge? The world may never know...

I wonder how does the mini measure battery SOC. Just voltage or does it count used energy from fully charged?

I've found the SE's battery consumption to be very linear. What's non-linear is the GOM, which is constantly adjusting itself. When I get under 30% SoC I've seen the GOM in some cases sit at the same estimated range value for 10 miles of driving. And in bad weather conditions I've actually seen it go up as I drive.

If using % of battery were perfectly accurate, then the estimated range would be independent of the initial state of charge. However, that is not what I have observed, even if you eliminate cases where starting from "100%" seems to give some "free miles".

Data 1.webp
The above data are based on my charging history, but I see the same thing along the way. That is, without any deliberate change in my driving behavior, my estimated total range (based on distance traveled and % of battery used) will be highest when I am closest to the top of the "tank", then decrease moderately (e.g., from ~180 mi to ~160 mi) the further I go.
 
Just a short follow up report:

Today I drove 77 miles, which required 50% of the battery (i.e., estimated total range 154 mi). Not really unusual in my experience, except for one thing: over half that distance was on the interstate at 60-94 mph, with much of the remainder at 45-50 mph. I didn't take note of the average speed, but it was clearly much greater than the usual 30 mph for my commute.

I did wash my car on Monday, and treat the exterior plastic trim this morning before I left - maybe that explains it...

Can you help me out to estimate my driving today bc all this is so confiusing when we estimate milage on SE .what is wrong with my estimate and I really would love to see that. Big number on dashboard not estimate than I believe how far SE can drive.Today to round a milages I drove 74 miles and you see on dashboard my picture and from my SE apps you see I used only 40% of battery for 74 miles which I start with full charge 100% if I use again 40% I travel again 74 miles total 148 miles but is still there 20% which should give me 37 miles as adding those numbers 74+74+37 =185 miles .i wish to show you that 185 miles on my dashboard or anybody else can do it not just estimates on paper .So far Curious George Proof his 161 miles (1) and Rexsio with dashboard 126 miles and Puppethead 120,2 on dashboard which I’m sure everyone can achieve those numbers but where a those guys with above 150 miles again on DASHBOARD of SE .Also is not a case to drive 150-180 miles at 20miles/hr just combine highway /city driving like you use SE daily IMG_1505.webp IMG_1504.webp. My SE is only hitting 92 M/hr with 16” Hankooks

I never achieve 120 miles 100% charging at home L2 this was public charging in 92 F heat after driving 63.5 miles

Lot of driving today, almost all of it freeway (I used green mode only for the last 20 miles, everything else was mid mode). Also temperature was in the 80s today so I had the AC going. With 17% SoC left I'm sure I could go another 20 miles easily, and the MINI Range Calculator agrees.

With 87000 miles over and range 156 miles you are a champ all the way on this forum bc of my patern of driving I’m never get there bc my one way drive is 70 miles from Staten Island NY to Connecticut on Sport mode challenging every Gas gasler on a road and range anxiety to not return home on one 100% charge I’m charging SE in CT always to 100 % again arriving home with 50-60 miles range depending of traffic patern bc of my spirited racing’s driving with full enjoyment of SE so far knock a wood no speeding tickets .I can’t drive like old man yet as I’m old already.

Todays little trip. D.C. and back. Multiple charges... Total time out of the house 18hrs, 15minutes. I was at my appointment for about 40 minutes, and not charging. A few charges were a bit longer than the car needed while I slept, shopped, or relieved myself.
I did the same trip on Monday, too. But that took 3 hours longer in total. I ran into no less than 4 dead DCFCs on the way up on Monday, which made me late and I hit really awful traffic instead of just the horrible traffic today. Longest leg of 112 miles. First one almost as long. Only one charging problem today. EA wouldn't let me charge at my penultimate stop as I was apparently still charging 190 miles away. About 20 minutes to get them to start me manually from their end.

IMG_0381.webp Here is one of my best runs. Driving in the mountains, even if you go both up and down, helps a lot.

Additionally, the other day my GOM stated 49 miles of range and my navigation said it was 49 miles to home. It was 60-70% highway and the rest in town. I didn’t want to stop and charge so I went in Green+ and got 6.5mi/kwh.
