For most part I've been on the default Personal setting, regenerative level on Adaptive, distance with preceeding vehicle set on Medium.
Only very recently i changed to EFFICIENT mode on my daily use. Curious of exactly what are the changes to the characteristics and driveability.

1.There's no noticeable loss/gain of response from the accelerator pedal, i expected some laggy response like in some ICE vehicles
2. Aircon setting no change. Still as cold, air flow from the vents same again i expected some loss of cooling in cabin to conserve energy
3. The default display of a big BLUE Diamond in my HUD is annoying. Just like i have to select EFFICIENT on my Modes every time I start my journey because is always in Personal( doesnt it). So 2 adjustments to be made everytime i start a journey. One get into EFFICIENT mode, secondly get rid of the BLUE diamond in my HUD.
4. The BIGGEST difference or change is in its regenerative braking manner. Its smoother, later and appears to "read" the surrounding better to accommodate a smoother(hence efficient?) transition when braking.
5. In assisted driving, the EFFICIENT mode doesn't work, only when self driving.
6. On the MyBMW app, almost every leg/journey regsitered appears to show and suggest better efficiency in term of kwh/100km( I'm in Singapore). However over a few hundred kilometres of same routine routes, the iDrive reading on kwh average usage is very marginally(little)better than when I'm on PERSONAL mode. The improvement in EFFICIENT mode is less than 0.5kwh/100km.

Further test and longer distance over a period on my routine runs would certainly confirm or debunk the EFFICIENT mode. I do many and most routine trips of less than 15km(9 miles).
Does anyone know what EFFICIENT mode takes account into or which part of technology involvement in the iX that driving on other modes doesn't?
After a month or two in EFFICIENT mode, i might try SPORT mode for a few months

As for the other modes like Expressive,Relax i think it doesn't change the car characteristics from a driveability point of view. Does it?

I'm going to have to disagree with you here. Efficient most definitely changes the pedal mapping to require a deeper press to get the car moving.

This is not correct. In assisted driving, the acceleration in Efficient mode is dampened. It accelerates much more slowly in Efficient mode under assisted driving, reflecting the same pedal mapping you feel when driving yourself.

When I put the car into efficient mode, the range estimate instantly increases by 10-15 miles.

[deutsch100]

I have to disagree with NomoTesla about efficient mode adding range miles.

Switching from Personal to Efficient, I see a 0-5 miles difference. Most times it is 0, but never more than 5 miles.

I do agree though with NomoTesla....efficient for sure changes pedal mapping, and the go pedal is nowhere near as responsive as Personal or Sport mode.

[SGiXers]

I do not have a measuring equipment something like Racebox to do a timed run from 0-100kmh to be able to substantiate the butt feel that on my iX40, the response and acceleration is reduced in EFFICIENT mode. Could be either the iX40 have limited performance that it didn't have much more to reduce even in EFFICIENT mode or my usual driving style is of the less hurried manner. Maybe one or both.
Sure,granted that both your goodself can feel the difference i don't doubt that.

As for the actual power savings, i see every journey on my app showing reduced power usage including claimed longer distance in the instrument cluster(;with Bonus range increased), but the proof is in the pudding. The kwh/100km in actual, shows next to no savings. I take a photo and also note down the Journey data screen everytime i charge my ride to know the ACTUAL consumption of power from the previous charging session.
I read it EFFICIENT mode doesn't work in cruise control in the iX owners handbook.

Hi
We also have an iX40 and we notice little difference between Efficient & Personal modes on both acceleration or range.
Maybe the other people who replied see more difference - because they have more powerful iX50 or M60 models?
I have a Racelogic performance box and did do a 0-60 run in Sport mode on our iX40 and can confirm that it is indeed much quicker than the BMW posted figures!
BMW quote a 0-100km/h of 6.1 seconds - this would normally translate to a 0-60mphh of around 5.8 seconds.
In actual fact - I measured a 0-60mph in a very respectable 5.26 seconds (which is not that much slower than our 2019 X3M40i that our iX replaced - that did the same sprint in 4.56 seconds)


Cheers

Incredible acceleration numbers indeed. This is totally under promise and over deliver on the part BMW.
Yes i reckon so too, the iX40 has lesser performance to detune to make it efficient, in reality i read the motors are the same with the iX50 albeit restricted on its output because of the smaller batteries.
So the bigger variants have to be detuned far more to get it closer to be in the efficient zone.
On my regular usage 4.5km/kwh is the best i could get from my iX40.

Those are great number for a IX40!
What was the level of charge?
Thanks.

Hi
It was well charged for this test - at 96% SOC


When I get some time - I might repeat the performance test with the different modes, to see what (if any) difference I get in the performance between Personal, Efficient & Sport modes.

Yes please. I Would love to see the comparison between the different modes. Thats the best and removes a lot of subjectivity. Now maybe i will get to prove whether my butt feeling was well "calibrated".
I really dont feel the difference in acceleration in EFFICIENT and Personal mode. Maybe the iX40 is that different.

[ThomasWeiss]

If you switch to Efficient while accelerating, you should definitely feel a decrease in power.

100% Maybe it is because it is the 40 model, and we do not have this in the USA, but putting my iX into Efficient...there is a prominent decrease in power!

[SteveX3M40i]

I can tell you than on an iX40 there is absolutely no difference feeling in the performance no matter which mode you choose.
The only difference you notice between modes in the screen colours and layout along with differences to the iconic sounds.
In Sport mode the seat also hugs you more!

I actually figured out how to get rid of this today! There is an option in the HUD options settings to turn on or off Driving Modes Display on the Standard HUD display...turn that off and no more blue diamond!

Pray tell dear friend what must do we do to get rid of this monster of a blue diamond in the HUD. I have to manually scroll my steering wheel button to change my HUD display on every new journey.

Legion of iX40 owners... please confirm this. I feel the same. No difference in pickup or acceleration characteristic in Personal or Efficient mode. Only difference is smoother(gradual)adaptive regenerative braking. The colour on the screen changes according to the different modes thats all.

It's here in BMW iDrive [Displays] app. You can use this menu in the [Head's Up Display] section to disable the blue diamond, etc.

Fantastic. Got rid of the blue diamond. Exactly the way I want it. Thank you. One or two more items in the iDrive menu regarding speed limit i need to clarify too,later.

[Yorick123]

For sure, my ix50 drops air suspension when i go to the efficient mode on

[SGiXers]

Just did a recharging session to get an update on electricity consumption in kwh/100km. I usually do this reading every charging cycle over 200kms of usage. Usually every 5 to 7 days of usage. TOP photo= first full driving in EFFICIENT Middle and Bottom photo= previous 2 cycles of driving in PERSONAL mode
A savings/reduction of energy by 1 to 1.5kwh/100km. Will continue to do a few cycles of EFFICIENT mode driving to ensure a more accurate comparison.

On my iX40, there's no feelable difference in acceleration and response when I'm in EFFICIENT vs Personal. Just the braking in EFFICIENT adaptive mode is far later and smoother as if COASTING is the preferred action iso immediate regeneration braking using adaptive setting in Personal mode

I can feel the decrease in power aswell but it is not the 40 model, so perhaps because of this.

[SGiXers]

Latest reading using EFFICIENT mode throughout from last charging session.
Best average reading for me considering most journeys are below 10miles(16kms), hardly reaching optimum cruise speed near 100km(62mph) and air-conditioning on in tropical Singapore.

If anyone has the ear of BMW, they really need to introduce a “snow” drive mode. They can even call it something fancy instead, I don’t care, but essentially it would just be a shortcut to reduce throttle response and adapt regen to be low.

This is a pretty important one, as mentioned over the winter I found the iX fine in deep and wet snow but on icy roads you get these micro “wiggles” when the regen kicks in, feels like it is losing footing. Not confidence inspiring at all.

It would be the super simple for them to fix. Rivian did this via an update too. https://stories.rivian.com/software-update-snow-mode
