My name is Isaac and cars are my hobby and passion.
This video is a brief description of BMW's "Energy Flow" from the recently added Mild Hybrid 48 Volt generator.
As of 2021 6 cylinder BMW models removed the Auto Start/Stop function for the engine. They replaced it with something way better for performance and efficiency. Auto Start/Stop was when the engine turned off at a brief stop and starting again just before driving off. The performance and efficiency are much better with 48V. I can speak for the efficiency side due to my driving style. One thing that changed is the the sound of the exhaust. Prior of this model popped and crackled much louder before this system so there is a trade-off.
Anyway, the upside is they installed this Energy Flow screen for fun viewing and understanding. That is what we are viewing in this video.
Enjoy!

I’m glad I got a 2021 X3, and not the 2022 with this mild hybrid crap.
That would drive me insane
your battery is too low for eboost. that's why. It give 9kv/11cv . I personally don't feel it anyway.
Thanks for this! I just got a x3 m40i and it’s amazing
Congratulations! A car without competition in many ways.
I have a 2023 BMW 540i i purchased brand new late june last year, no one ever explaiend how this works, great explainer video.
Thank you! I hope you are enjoying your 540i.
Excess weight and long term problems. Shame.
How i van see when its fully charged ? For the eboost? Because i see when its charging but its not giving me the eboost
nice to see how that works. clearly explained too
Thank you for watching
Nice informative video . I had no clue how Mild Hybrid works and I reckon X4 M sport has this feature .
Thanks again
X4M does not have it yet. X4 M40i has the feature. 30i does as well, but no generator yet
Would tuning/modifying the b58 be bad with the mild hybrid system? Please let me know just picked up a 2022
No. As long as it is done correctly. They push 470+ horsepower easily. Which is M3 power. Try to stay inside warranty while it is still active.
Thanks great vid. Can the MHT battery run Aircon or heater while the engine is off like if your were parked somewhere?
For a short period, yes. That is part of its purpose. It is reliant on your driving habits. You might not have any juice during sporty and stopping. Driving downhill works wonders.
Does the tachometer layout stay stored even after turning off the car?
I read online that on the earliest versions you had to set it again every time you turn the car on and I was wondering if they fixed it.
The Tachometer stays permanently. Make sure you have a profile set up beforehand.
If you haven't got one why does it matter?
@@mariemccann5895 if you have one, you wouldn't be asking the question, you'd know the answer.. lol? I don't have one, but I'm trying to learn about the BMW and the mild hybrid system so I know if I want a M40i, or an SQ5?
Yes, I changed mine where it shows the battery meter and my music album cover shows up in the dash board I love the dashboards in BMW it's definitely a cool feature in BMW's.
I have a g20 from 2019, 318d and it has MildHybrid, so not only the ones from 2021+ have it..
This started in 2019
Not easy to understand the principle. Will do more research on that matter. Thanks.
Thanks for watching.
Appreciate you man! I got 2021 540i xi
Welcome. Great ride, you got there with a perfect luxury/sports car mix.
Very similar to my Ram truck with eTorque. Do you know if BMW replaces the alternator with the generator as well?
I am not sure about alternator, but the system powers everything when engine is off including power steering
@@theautointuitive3172 yeah same as the Ram. It has some affect on mileage, not a ton but add some torque and makes the start/stop very smooth. I just bought an X5 so curious to see how it works in the BMW when I pick it up.
@@tinshield same way exactly. So excited for you to get your TwinPower Turbo Mild Hybrid Inline 6 mated to one of the best 8 Speeds out there. Is it an Intelligent xDrive?
@@theautointuitive3172 yes, it’s my wife’s car. They bought the lease out on her X3 M40i. Looking forward to a little more space!
Soo the 2019 m340i is not mild hybrid as well?
That's right.
Why dont have reduce mode. What version idrive your using.
idrive7.
can I see the energy flow on the OS8 too?
1 % better every time...getting better.
Thank you!! 1% closer.
Bro the 2020 doesn't have mild hybrid ?
2021 320D MHT; is this a good option for short drives? And not constant long motors way drives?
Just got one. Same year etc. did you buy one
My energy flow is always fixed in level 2 or 3, have you ever managed to get it full?
Quick takeoffs will drain it in Sport Mode. Also sitting in the car in Drive Ready State. Anytime the engine is off via Auto Stop/Start and Air Conditioning is on also drains it. Try driving it in Comfort or Eco modes on Highways and freeways. I am also rare full due to my right foot.
I’ve just got mine. Have you figured it out yet?
I have an M440i xDrive with the same setup. You can get it to full while driving it in Sport or Sport Plus for a while. No quick accelerations though as it will drain the battery. Medium to hard braking will charge it up faster. Driving in Eco Pro will never get it to full as the engine will turn off as soon as you leave the gas pedal unless you are hard braking every time. When the battery is charged to 4 bars or above, the electric motor will assist the engine in even casual accelerations. It will provide the Eboost functionality when in Sport modes which can be seen in the Energy flow screen as Electric Motor Assist or something and you should be able to see 2 arrows (Blue and Orange). It’s actually kind of cool to see and know when these complex things are happening in the background. Personally, I drive mine in Eco Pro 90% of the time trying to take advantage of it’s efficiency and Sport Plus the remaining 10% of the time when I want to have some fun. Almost never in Comfort, Adaptive or Sport. I use the Sprint mode when I quickly need to pass someone on the highway as it is the quickest mode you can access while the car being in any mode. You can try it by holding the left paddle shifter for a few seconds. The car goes full Sport on everything I think, downshifts to an appropriate gear and puts the transmission in manual mode so you can quickly switch gears when needed. This will automatically go back the previous mode you were in after some time when you’re done using the power or you can manually do it by holding the right paddle shifter and it takes you back to the previous mode. I have done so much research on my car. Read a lot of forum posts. Literally read the entire 300-400 page manual that comes with the car. Let me know if you need any help with any feature only as an end user as I don’t know nothing about fixing these things or have any knowledge about the mechanical stuff lol
@@anuragreddykanuganti3187 thanks mate, great answer, i ll try
Thank you
Welcome!
I’d rather avoid having this hybrid silly thing. that’s gonna be problematic after some time for sure
My exact thoughts
Actually the mild hybrid system in BMW's are very reliable.
Do -20d models have mild hybrid too?
I don't think so and not sure. I am in U.S. where New diesels are no more. The 30i doesn't have it. 40i were the 1st confirmation. 60i/M60i V8 engines are next. 2023 BMW X7 M60i currently is the 1st confirmation.
@@theautointuitive3172 All right. Thankyou so much sir
yes 320d models are hybrids, too
yes i have 420d xDrive
bmw makes such smooth inline 6 motors, add a mild hybrid and it’s just buttery!
It's like eating fudge and feels like an 8 cylinder
This technology puts massive pressure on starter motor which eventually fails causing many other parts to break which happened to me... Either go fully diesel/petrol or electric, not this.
How can you turn off complettly the star stop engine
Sport mode only pal
@@rosco3223 yeah I see😵💫 thats why I didnt bought that car
@@rosco3223 It will burn fuel like mad, this 'technology' is madness..
@@mikolajosypowicz2541u can go in sport individual and turn everything to comfort. I Drive on this 90% of the time it eliminates the auto stop start and get to keep driving in comfort
