    Thanks, insightman, that’s helpful info. :) Like I said, I really wasn’t sure if an indicated 100+ miles of range was at all commonplace.

    And yeah, I’ve known to ignore the GOM for months prior to taking delivery of my SE last week based on reports from just a few of the more discerning reviewers out there and actual owners like you here and elsewhere. And to your point, I’ve only kept that lower-right readout set to show my battery’s SOC since before I drove off the lot, because I know that’s the truest gauge of range we have.

    But I share Chicago Ken’s interest in the highest miles-of-range numbers people are seeing in their cars for Sport driving mode (as well as the other driving modes, for that matter) just to be able to see that data and compare notes. Not only to help set expectations, but also to see if anyone might be having a better experience with the GOM (as highly unlikely as that might be) perhaps due to…more consistent driving patterns than the norm? Who knows? o_O

    I think this is the closest to the truth. I was the first to get an SE from my dealer, and they did put in a Level 2 charger before it came, but the unfamiliarity with BEVs for the dealers takes some patience. As MINI introduces more EV models it should get better.

  5. We got our SE with 100% SOC with a mileage of 10k. After days of being frustrated with the GOM I have always measured the SE with SOC, 100% is always my aim and 50% is the lowest if I want to hit my discounted rate of charging at night, and definitely charge at 20%. I think it was @insightman who said SE should ABC. Anyways to answer the original question on this thread, after charging to 100% I always get 161 km or thereabouts on the GOM.

  6. Have you ever watched the loading of cars onto a MV Carrier?
    The guys driving the cars onto the ship are likely paid by the unit and the logistics company wants to load and offload as fast as possible to save on port charges.
    I watched for about a half hour at a port in Spain loading new cars. No doubt in my mind they were using 95% throttle. And you could hear the squeal of rubber on braking and turns on the decks.

    I asked the dealer to change the charge settings and have my SE fully charged for the 50-mile trip home. He told me he told the service guys, but didn't check it himself. When I got there, he informed me that they didn't do it, so I had to wait an extra half hour until it reached a sufficient SOC. I remember that it was nearly equivalent to the GOM (1%=1 mi).

    Now that I've had it for a month, I'm usually seeing around 109 mi for 100% SOC. I always drive in sport mode.

    Car default settings can vary dependent on sales market. In UK our charge rate was set at max. No MV carrier here and car fully charged on forecourt. Initially sport mode indicated 115 miles, Green+ 120 miles. Now there is no difference across modes and a full charge is only 109 miles. In summer mini at 100% would get to and back from railway station without top up, but not now.:(. Using a pre boost and climatisation to heat cabin prior to departure helps for comfort although no extra mileage gained. Discrepancy between app range and car range, (105 v 109 miles), but car seems closer, nowhere near the official EV range of 144 or the "real" range of 130 miles. However the car is fun to drive.
    Main problem with mini app is that no round trip planning is possible only one way destination. Most frustrating.

    My GOM showed 130 miles when I picked it up, but I didn’t photograph it.

    I had a very disappointing run in the Mini today. We went to Murrayfield in Edinburgh as we go to all of the home Scotland rugby games, so I wanted to see if the Mini could get us there and back on a single charge. I didn’t see too much of a problem since the entire trip is just over 78 miles.

    I charged the car ready for my planned departure time (set in the car as my app still won’t allow me access to the charge and climate timer) and preconditioned the cabin, so we left home with 100% SOC. It was raining steadily and was quite blustery, but it was reasonably mild at 9 degrees C (nearly 50F). I drove in green mode from the off, and consciously never accelerated above 50% power. As the vast majority of the trip is motorway, I set cruise control at 70mph and never strayed above it. The AC was on and set to 20C in the cabin. We didn’t use the seat or steering wheel heater. I used exactly the same route in both directions, so the only real variable was the wind. I was able to get to Murrayfield and back; only just. I arrived home with 4% SOC left, and warning messages telling me I had less than 2 miles range. My entire trip was 78.4 miles. The trip computer said I had consumed 2.8 miles/kWh. That is appalling given the way I was driving. If I’d been hooning it, drag racing from every standstill and cruising at 80 then I could understand it but it was the dullest drive possible and I still only just made it. The analysis tool with the fish bowl gave me 5 stars for acceleration and anticipation, so I don’t know what else I could have done. I arrived at the stadium with 58% left, so I used 42% on the way there and 54% on the way home. I didn’t feel any tailwind on the outward leg, but I did feel gusts of wind on the return leg. Nothing strong enough to significantly bend trees, but it was definitely noticeable. I am now wondering if there’s something wrong with the car. I’ve ignored the pessimistic GOM knowing that most people on this forum say they can get 100 miles range in winter and I was OK with that, but it’s not even particularly cold and I couldn’t even get 80 miles in the car despite driving it like it was made of glass.


    Does the range improve after a few charging cycles? I have only done 170 miles in the car with two charges, so maybe it’ll improve? Failing that I’m stumped at how so many say they can get 110 - 120 miles driving around in sport mode. For info I don’t have roof rails, the only external add-ons are the genuine mud flaps front and rear and they’re so small I can’t believe they create enough drag to drop the range that much. I have the standard fit Hankook tyres on the car too, all set to the correct pressure. I’m feeling quite disappointed tonight.

  11. I can relate @SpeedyRS, though it is summer here in NZ, my last trip of 5km consumed 23.8kWh/100km, outside temp is 21C and I had the AC at 17C, so probably it was the AC eating battery power.

    Rain, in addition to wind, warming the cabin, and lower ambient temperatures, reduces range, too. The most disappointing aspect of your trip was that you kept the fish happy. When the fish is happy the driver's not having any fun.

    I’ve had similar experiences driving on the freeway in the rain when I’ve used over 1% per mile. 70mph is definitely when you get into exponential wind resistance loss, especially when it’s rainy. Even going 65mph would save you 15% on drag, in theory.

    Mine reads only 80-100 miles at 100%.

    It does not seem to reflect reality in any consistent manner, so I ignore it completely. The battery % (via the button on the turn signal stock) is all I pay attention to.

    I’m curious about this too. I saw some folks in the Toyota Rav 4 Prime section say that if you drive conservatively, the EV range will slowly increase over time. Never heard that on the MINI forum section though
     
  17. Ha ha, don’t think anybody here drives their SE conservatively. I know I don’t; it is a MINI and I drive it as a MINI, I don’t even drive in Green mode.

    Thanks, mole and Speedy, for sharing your GOM readings when your cars were brand new and fully charged! Speedy, the 130 miles of range, especially, indicated on your brand-new car when you first picked it up does renew my interest in the possibility that perhaps the highest mileage range figures the GOM will ever provide may be at the very start of ownership before it’s had any meaningful number of miles put on it to “learn” from. Hmmm…

    But more immediately, Speedy, it’s hard for me to get my head around the fact that your car barely made that 78.4-mile trip — especially at 50F degrees, which as you point out isn’t particularly cold. Yes, the 70 mph speed and the rain and the wind and slightly colder temperature all contribute, as others have pointed out, as does your use of HVAC…but I’m very disappointed by this outcome, too. (Although I do greatly appreciate your sharing about the experience, as disappointing as it was, especially with all the data you included! That detailed info is always useful for this community as we try to figure out our cars’ capabilities.)

    I do remember YouTuber Bjorn Nyland reporting, in his range test of the SE during dry, 19C (66F) weather that he was able to travel 147 miles at 90 kph (56 mph) but only 101 miles at 120 kph (74.5 mph). I would not have expected your range to be decreased by 20 miles compared to his 74.5 mph range figure due to the combination of factors you reported (including being helped by traveling at nearly 5 mph slower than he was), but I guess they just all compounded to do exactly that. Which is a hard pill for me to swallow, too, as a new owner like you. (I thought I’d prepared myself for the practical limits of the SE’s range in all the research I did, then I hear a real-world account like yours and I find that it really has me coming up short, you know?)

    I think Bjorn might also have had an opportunity to test the SE in the rain; I’ll try to find that, FWIW.

    Tha
    That’s true because I had no fun at all yesterday. Damn that fish!


    That’s exactly what I did. I wasn’t complaining about what the GOM forecast, I’m disappointed that after 78 miles driving like a very conservative nun I had 4% battery remaining.

    I have no intention of driving the car for economy, but I do want it to be able to do a trip of 78 miles from time to time without having to stop and charge or bore myself to death on the road. I ride sports motorbikes and drive like a sportbike riding motorcyclist which was one of the attractions of the Mini as it allowed me to dart into gaps, go into bends at speed without worrying about ending up in a hedge, but it absolutely should be capable of doing it according to pretty much everyone on this and other forums, mine just doesn’t seem to at the moment. I’ll keep at it and will try another trip. I do love the car, it was just a disappointing first “long” trip. Hopefully there will be better days in the car ahead.

    I've also had one trip so far with a horrible efficiency of 2.7 mi/kWh (78mi range) and it was pretty similar conditions to what you experienced (cold, windy, and a bit rainy).

    The wind is the real efficiency killer, even if it's just gusty. I've had plenty of trips that were just cold and rainy that ended with much better efficiency.

    On the way there you got 3.2 mi/kWh which is close to normal for 70mph in the rain. That would be a range of 92mi.

    Because EVs are so efficient, the small losses that would be negligible in an ICE car become significant. A fact that really puts that into context is the amount of gas equivalent to the SEs battery. At 100% charge, you are really only driving around with 0.87gal of gas in your "tank"!

    50 ºF should not be cold enough to affect range. While the air will be somewhat denser, the heat pump still functions well at that temperature. I've had over 5 mi/kWh at lower temperatures.

    That’s very helpful info — encouraging, too, especially how efficiency for the first leg of Speedy’s trip really wasn’t bad considering the conditions.

    I did find that video Bjorn Nyland shot of driving the SE in the rain; while he unfortunately did not report the temperature, he found that driving in the rain caused the SE’s energy consumption to increase by 18% at 74.5 mph (120 kph) and by 20% at 56 mph (90 kph) compared to driving at those speeds on dry roads (in his range-test video I referred to last night).
     
  23. I took the delivery today and luckily remembered to take these snaps that shows mid 114 miles, green 130 miles and green+ 139 miles range.
