@ssh thanks for the information. I know I’m late to thread, but I just recently took delivery and was quite annoyed with my 220 max miles at 100% on my GOM. I called the dealer and demanded my 272 miles, LOL! Not really, but it was annoying.

I did notice that the car charges if I’m cruising at a decent speed which helps my psyche!

Thanks! 😊

I’ve been quiet on this forum the past few weeks (needed a detox after my PPF, tint etc saga) but came back to see what people are saying about range estimates. I’m at just about 1k miles on my eDrive40 and somewhat surprised how low the GOM estimates have been. I’ve been averaging 3.0 mi/kWh and do fairly spirited driving (love the car so I’m going to push it each time I drive it!).

I read through this thread and realized I should probably give B mode another shot. Well, I used it this morning on my 20 min commute to work which includes curvy local driving and highway driving and averaged over 4 mi/kWh.

So for anyone disappointed in their range and range estimates, try B mode if you haven’t already.

@ssh won’t like this post. You’re in trouble

Joking aside, I exclusively use B-mode (make sure you enable Auto-H also for full one pedal driving). On the freeway I engage ACC/DAPP and I’ve been getting above EPA range.

What are you taking as EPA range?

What did you use before going to B mode? The big difference with B mode is that the motor control pedal gives you the maximum recuperative braking possible without using the brake pedal. The other modes use the brake pedal for at least some of the additional recuperative braking after removing pressure from the motor control pedal.

However (and this is really important), all modes offer the same recuperative braking. The difference is in how you manage it with the pedals. And, it seems to me, many people are more aggressive in their use of the brake pedal when in the D modes. That's likely your big difference.

I had the regen braking set to Adaptive in D mode. I would only occasionally feel the regen braking engage and for the most part I used the brake pedal as much as I would in an ICE car. When I switched to B mode today it was a very noticeable difference in braking and I hardly needed to use the brake pedal.

Is D mode with regen set to high the same as B mode?

No. There is still some recuperative braking which happens with the brake pedal in D/High.

Your 271.

Ok, what do you mean then by it's the same amount in all modes? Doesn't B mode provide the most regen braking?

 

[ssh]

No. It provides all of it with the motor control pedal. The other modes use the brake pedal for it. The challenge is if you push the brake pedal beyond the recuperative braking power of the motors (visible only in the meter on the instrument cluster showing "Adaptive") you'll blend in the physical brakes.

Interesting. Well I have been working the brakes pretty hard for my first 1k miles. I've been very impressed by how strong and smooth they are and even thought to myself I would probably go through them pretty quickly given how much I've been using them. I guess if I use regen breaking more I'll extend the life of the mechanical brakes.

Yes. Depends on if you hammer them (you'll blend the physical brakes in right away) or ease to a stop.

If you are going down hill, I can almost guarantee you will get more regeneration with B. The question is what is more efficient, constantly regenerating downhill or coasting and trying to squeeze the regeneration in a small window when you break. In my experience, feathering the regen with B gives better results than "coasting".

@ssh, I would love to see if you could drive home on your downhill route for 1 week on D-adaptive and 1 week on B and see what results you get. I have a small hill on the way home. D gets me home faster because I coast at a faster speed, but B bumps up my m/Kw by .2 in 1/10 of a mile as I regen the battery.

You can't guarantee it. The only way this is true is if you fundamentally disagree with the logic and physics behind blended braking systems. If you drive down the hill at the same speed you will get the same result. If what you are saying is true, you have to question why bmw went to the trouble (and expense in the uk where adaptive is free) to create Adaptive braking. The whole point of Adaptive is that it optimises efficiency by coasting where it can. B can't do that without considerable care. And if you can be that careful when using B then I can be that careful not to use friction braking when pressing the brake pedal.

I use a lot of DAPP on the route, so it recuperates on every downhill as it maintains speed. In fact, I gained a few percentage of SOC on a couple of the longer downhills. When I use the brakes, I pay attention to the Adaptive meter and work to keep it above the bottom.

I'll try B at some point, but it drives me nuts since I have a challenge keeping it in "neutral" so it coasts.

Don't disagree with most points you make. I'm not assuming same speed as that is harder to do, as I said, I go slower in B. BUT, I'm guessing slamming the regen in a smaller window with late breaking is not as efficient as constant smaller regen which B mode allows much better than D. In my downhill example, you will be more efficient if you are 5% braking the whole way down and going slightly slower than if you are free coasting (faster) and break last minute.

When we are talking on this forum about comparison we never talk exact apples to apples. But maybe guarantee was strong but I'll bet on it and win...

Happy to move on now but would still contend that if you don't use physical brake pads then Adaptive will match or better B. It can't be worse. What you are saying is using B reduces the odds that you drive like a cretin and coast and then apply sufficiently aggressive braking so as to utilise friction pads. I won't argue that there aren't people out there that would do that!

@yobro 24, this is really well said and precisely correct. It's really hard for people to get, but it's simply the mechanism by which the brakes are blended which seem difficult to grasp.

Well... I can personally guarantee that the way I drive on those long runs to and from Copper I do not brake sufficiently to use the physical brakes. Plus, there are a number of stretches where I vary between full coast and recuperative braking. I do not do 90mph down from the tunnel to Silverthorne and then slam on the brakes to hit 65 before I pass the location of the typical LEO positions at the bottom of the grade. I go down the hill at a constant speed (often by virtue of setting the cruise) and let it recuperate. Last time I did this I picked up 3 or 4% of SOC on the 13 mile/15 minute downgrade.

This, by the way, is a habit change. With an ICE, I had to be very careful about braking due to potential overheat with those kind of grades. Now, I can happily use the brake pedal to feather my speed and coasting without being at all concerned about brake temps. Every once in a while I find myself coming off the "brakes" to let them cool and then realize there's no need. Kinda cool.
