So after a day of playing on a full charge discharging to 6 miles, driving it back up to 12 miles with regenerative braking, then a full overnight charge , I wake up with 44 miles of range. How is that when we are only supposed to see about 30 miles of EV range?

It’s because it is an estimate of range based on how you drove the car just before you started to charge it. Also the anticipated weather. My car has estimated all the way up to 48 miles of range at times, but as soon as you drive it the numbers will adjust. Regularly I get between 33-37 no matter what the estimate is

your 45e is new with not a lot of driving, so the vehicle thinks you've been very efficient and reflects that in the electric range upon full charge. this is normal behavior for new 45e, and many new folks get excited initially when seeing this. after a few weeks of regular driving, you'll start seeing a more 'accurate' number that actually reflects how you've been driving. it bases this number on the previous ~18 miles of driving in addition to other factors such as ambient temperatures, battery temperature, HVAC use, among other things. this number can vary widely if your driving varies from day to day. regardless of what you see, you always have 17.1kWh of usable capacity.

that being said, you can still affect your electric range by adjusting your driving style, reduce HVAC use, and taking advantage of regeneration whenever possible such as going down hills. i average 34-37 real, driven electric miles in the temperate seasons due to my consistent daily commute. it will drop during the winter months. YMMV, literally

congrats!

Thanks for the updates and tips. The thing is absolutely amazing though! I can't believe how "light" it feels when you hit the click on the accelerator at almost 1500 pounds heavier than our X3 M40; and we only used 1 gallon of petrol in 89 miles!

i agree! it's been one of the best purchases in my adult life. i once went 7 months between fill-ups; currently 5 months since last fill-up and still 50% full (I do instill fuel stabilizer, debatable)

Miles to empty (for both the ICE and EV) is based on the previous 18-miles or so of use, and is a moving average. So, unless the conditions are EXACTLY the same as in those previous miles, the future miles won't agree. It could go up or down.

I'll tell you what's more impressive? The last time gas was topped up in my 45e was July 1st, and it ran 1200 something miles since then with 980 odd miles being full electric.

I expect performance from my cars (my other car being a '22 M4 M xDrive) and the 45e is not lacking in peppiness for its family SUV use case. I regularly corner the 45e in 90 degree curves with squealing tires now as I've gotten very comfortable with its limits, and it's near-flat cornering characteristics in the second lowest air suspension setting. And that's just in electric mode. Sports mode with manual shifting is like a decent sports SUV passing just about anyone with ease.

Enjoy!

hope you're not trying to flex (seems your 45e is new, too, so the explanations for the high electric range above apply)

[mobsync]

Put your cruise control on 45 mph everywhere you go and you can get pretty dang close to your 44 mile range. I got 2.5 miles per KW/h last night by going this speed to the grocery store and back home.

Just showing what it’s capable of on a stock configuration if you set your cruise to 68mph/110kph.

Should be good for 60-65mi in range unlocked to EU spec.

Anyone know if it's possible to code the battery up from the 17kWh to the Euro spec?

There is a software that does that...I'm not sure if it would affect the warranty.

Here is a thread discussing it:

meh, I got 47 miles after charging after my most recent road trip. the next day, I got 33 real miles on commute to and from work. have you not read the explanations above? that number takes into account the drive you just completed. it'll only mean something IF you drive EXACTLY the same way on your upcoming trip. if not, you're back down to the 30s for electric range…guaranteed

(you're not clear in your post. did you mod your HV battery to EU spec?)

Are you guys all using the default 19 in tires with these performance metrics or something larger?

I know that smaller is better for max EV range (and ride comfort)... but for only a $600 upgrade the 20 in tires definitely give the car a more fun look!

it won't be significant no matter the wheel size. the average actual driven miles in normal use case is the EPA-rated 31 miles. if you see any huge numbers, they're outliers based on factors mentioned above including battery modification

FYI my M Sport originally came with 21" but I switched to 20"

19 and 20’s are the most efficient but if there was a lightweight, aero 18 or 19 that would be even more efficient.

We run the 20’s on ours since that’s what was standard on the msport.

Where I live the cost per KWH is about $.38 on average. So, if I understand it correctly, 2.5 miles per KWH would cost $0.15 per mile for electricity. Is that correct?

For electric range...does it make a difference traveling via surface streets vs. freeways?

Did you switch wheels due to ride quality or efficiency?

It does. The best range is expressway with 50MPH traffic, minimal stop and go. Surface street with slow traffic and stop/go degrade mile/kWh just like how ICE car behave, just not as much. At higher speed, say above 70MPH, mile/kWH taper off worst than ICE tho.

I think the mile/kWh is only meaningful for round trip drive, where elevation change is equalize. Because I can always do a downhill drive and get 3+mile/kWh. In my recent attend to maximized EV range, it was a 30 miles round trip drive with mixed of local and free way. I limit freeway speed to 70MPH. this trip, I got 2.3mile/kWh with very gentle foot.

in a nutshell, yes. stop and go will decrease efficiency; doesn't matter if it's electric or gas. cruising on freeways is efficient, but at some point, the higher speeds can be counterproductive
