Being a Tesla driver for 4 years, very comfortable for the one pedal drive concept. Now after getting a new iX, I found I need to pull down the drive mode lever twice as the default mode is "D". Is there a way to make "B" mode as default?

Also looks like the "R" mode doesn't has a one pedal drive mode, this make things a bit tricky when parking into a small space, because with "auto-hold" enabled, both "R" & "D" mode can't easily start with very slow moving as "B" mode did. So I need to manually disable auto hold, and rely on pressing brake to slowly move the car. Is there a better better way to enable parking in small area?

I've never turned on Auto Hold for parking or maneuvering because it's so imprecise for making small movements. Same for the B mode that I've experienced - it will stop the car, but not as precisely as manual braking. I have a couple of inches of clearance for my mirrors when entering my garage, and probably 6-12 inches front and back. I'm not going to rely on the car to figure out when to stop. That said, it's a great idea to have the car remember all of your preferred settings - just like with your seat positions. Would be nice to have it start in the braking mode I set, or the driving mode I set. I seem to recall somewhere though, that it was a regulatory requirement for the car to start in the EPA-tested driving mode, but can't verify. And I'm guessing, from a liability standpoint, BMW didn't want to set a default mode that might result in new drivers claiming "I didn't know it was in B mode!" after they ran through the back of their garage.

I cant agree with you more. It’s very hard to park when the auto hold enabled, especially in “R” mode.

In my opinion, Bmw should send a OTA to fix this issue ASAP before more accidents happen.

Auto Hold essentially applies the parking brake when you manually press the brake pedal, and releases when you press the accelerator enough to overcome it. It operates that way in every BMW (or any other car) I have owned, and is not an issue that needs to be fixed, unless for some reason it stops working. The purpose of Auto Hold is to keep the car stopped in traffic, or at a long pause like at a light, or in a queue, without having to continually hold your foot on the brake pedal. It's not meant to be enabled for precise parking maneuvers, just like using your parking brake isn't meant to be a maneuvering brake - it engages and disengages electronically, and applies the brake fully, there's no "light" or "heavy" braking. That's why there is a more precise manual brake. The B mode is new to BMW in this car, and as designed uses the engine as the brake to recover energy into the battery. It's not meant for precise maneuvering either, but is more controllable than the Auto Hold function which is "on" or "off," because BMW I think meant for it to work as brake and throttle while driving ("one pedal"), with the driver able to use the manual brake as needed without disengaging it. I hadn't really noticed that it doesn't work reversing the car, but I'm not surprised because I'm not really trying to recover energy reversing the car over long distances. I think both systems work as BMW intended them, which apparently is not Tesla's design.

The main issue happens at parking time. I need to explicitly disable auto parking to enable precise moving. This is an addition step can be easily forgot and cause damage during parking.

Great reply, very well thought thru

I like the BMW implementation of B mode a whole lot more than I did in my Model X; I drive exclusively in B mode and it not working when reversing is actually better because it is easier to control the rate of reverse with lightly braking rather than relying on the stop and go system Tesla has

What is the difference between "B" Mode vs "D" mode with "high energy recapturing?"

I think the "D" mode is always adaptive - i.e., variable (and less predictable) braking/coasting even in High regen.

 

[jeffgtx]

I asked a similar question in a previous thread and since then my experience is that B mode will come to a complete stop and D will not.

I'be owned a dozen+ BMWs and have had the same observation about inability to create my preferred setting as the default on such as transmission mode, braking mode, etc (depending on which BMW). BMW must have a process where they set the default and there is no way to change it.
