BMW xDrive All Wheel Drive System Explained
Вставка
- Опубліковано 22 гру 2016
- The BMW all-wheel drive system, xDrive, ensures your BMW has the best possible traction at all times, enhancing agility and keeping you safely on track, even on fast bends.
xDrive is the permanent all-wheel drive system from BMW: under normal circumstances, it distributes driver power between the front and rear axles in a 40:60 ratio, and changes this figure variably when the road surface or overall driving conditions change.
Acting virtually instantaneously and a manner so subtle as to be go virtually unnoticed by the vehicle's occupants, xDrive can direct up to 100% of drive forces to one axle. Enabling the driver to start up effortlessly even on slippery surfaces or steep hills, xDrive routes all power to the axles with the greatest traction. When parking, the system reacts to the need for high manoeuvrability at low speed by opening the clutch completely so the powertrain functions optimally.
At the first sign of understeering, drive power to the front axle is reduced. If oversteering is detected, xDrive directs more power to the front axle. Thanks to this dynamic redistribution of power, vehicle stability returns to normal even before the driver notices anything amiss.
Driving on a winding road or taking a fast bend in dynamic style is particularly enjoyable with xDrive: you feel as if your BMW is being guided along the curve. xDrive ensures that none of drive power is wasted on a loss of traction: every kilowatt of power is effectively brought to bear on the road.
xDrive is regulated by Dynamic Stability Control (DSC) and uses information from the latter system’s sensors to monitor road conditions. In addition, brake force courtesy of DSC is used when there is traction difference between the two sides of the vehicle and wheel spin is likely.

This dude makes me feel like a badass for owning a xDrive BMW.
It should make you feel like a fanny
@@adamali1774 if ya don't like em, why are you here bud
@@lukesecrest1687 I do like them but feeling like a badass driving a all wheel drive?
@@adamali1774 xdelete allows you to have just RWD. Imagine only being able to have RWD in a RWD only car. I can have fun drift around do donuts in the summer then come winter have AWD.
Same here !
I don't like all wheel drive. Every time I put the spare tire in the trunk it starts spinning.
HAHA
lol. you made my day!!!!
hahahhahahaaha
I see you have a some kinda demonic tire problem Or something like that
No spare tires for BMWs but still funny 🤣
The ULTIMATE driving machine baby
yes sir.
No one does it like beemer
Fundamentally explained thank you. Lots of moving parts with state of the art micromanagement in these cars. I’m only at 162,000 miles on my 13 X5d. Best cars for a mechanic/computer wise guy.
Have you had the drive-train fluids ( trans case , ZF and diffs ) replaced ? Did mine at 60.000 miles last year ( same as your model ) and the ZF responds better . Trans-case oil wasn't too bad either , but diffs oils looked fine .
@@npet6842 Yes I’ve changed the fluids using ZF fluids purchased from FCP Euro. I rigged up a 3-gallon gas can with a 12V pump mounted to the side, SOOW cord, big alligator clips, and a momentary on/off switch set up in ergonomically thump-push fashion. I dumped seven quarts of ZF tranny fluid into the gas can, connected to a remote 12V battery, transparent 1/2 hose, and then pump the fluid into the tranny. I have ISTA plus on my laptop, or you can read from the BMW dashboard, checking the tranny temp as you fill.
I refuse to drive any car without xDrive ... I always win the traffic light grand prix in my BMW x40d .... rain or dry it just sticks to the ground like glue. My previous BM 330d rear wheel drive, manual always slid out of control when I planted it and it was difficult getting the power down in the wet.
congratz on winning the traffic light prix
You win for the longest time in shop as well
💯
....until a guy with quattro shows up. A week ago bought a 2012 530d xDrive - and have had a 2008 A6 Allroad manual with 3.0TDI since 2017. Quattro doesn't slip. EVER. Even on extremely wet or snowy surfaces, iced tram tracks - doesn't matter. Just goes. It's just effortless torque and traction. However, with the bimmer - there are times the system slips, making the rear wheels "do their BMW thing" - making the car oversteer. Which is fun - but far from efficient - or safe - in case the driver is a loon. There are some qualities where BMW is above the audi - the AWD system is not one of them.
Ahhh, the quintessential BMW driver. Likely doesn't let anyone merge in front of him, and has yet to discover the inside lane!
Wait, actually in general driving, only one axle working till the moment sensors feel smthg then car automaticlly includes front wheel drive ?
Thanks for the video
So is xdrive a torque vectoring AWD system like sh-awd?
Is it possible to drive a car without body as it's shown here?
well, i you have a seat to sit on, i guess it's possible. i don't think why anyone would want that tho😂
No, it's not. That is a unibody car which means all components - engine, suspension, etc, are mounted to the body. if you removed all parts from the body and connecteted them again, you would end up with a complete tangle of loose wires, hoses, and mechanical parts. Additionally - any attempt to drive would end up in snapping the driveshaft - it's not intended to transfer compressing forces ;) You could drive a body on frame car like this just fine though, e.g. Ford Crown Victoria ;)
how about chassis ?
You see loads of truck chassis been driven up from the port to where the body gets put on, with drivers wearing helmets. So yes you can.
I can't figure out one thing, in dry condition, without loosing traction does all wheels has power or only one axle?
i wanna know this too and does dtc disable turn off fwd
Can be powered off?
Transfer case that is the heart of this is very prone to issues, and not cheap. Can you disable it safely?
no you cants, you would need the tranmission converted to rwd and hole front suspension from a rwd car. Removing the transfer case yourself will save you a lot of money.
There was simply a switch on the front differential allowing all the power to go to the rear on my 2008 328xi
@@chrismeister2190 wait, really? Where exactly? Have a link that shows this? Thanks, I have the same car.
What software was used for the animations on this

so its not an all wheel drive is an adaptive 4x4 ... i think people forgot what all wheel drive means...
It doesn't explain too much. There are different kinds of xdrive systems. It's hard to find the right info when buying a bmw. The same with quattro. So for example only in mperformance or M models you will find the high performance xdrive systems using central Limited slip differentials or for RWD a rear LSD. On most models you will find a cheaper drivetrain with torque vectoring by braking at most that is not efficient. The new x1 and 2 series have the cheapest layout and xdrive.
For xdrive and quattro a single lsd (audi uses torsen lsd) is not enough, as compared to a RWD. Si you need either more lsd's or some clever way for torque vectoring not by braking.
"The front and rear differentials in xDrive vehicles are typically an open differential design, thus relying on brake application by the DSC system to transfer power from the slipping wheel to the wheel with traction."The DPC differential features clutch packs on both output sides that are actuated by an electric motor. The clutch pack activates a planetary gearset which causes one wheel to be overdriven."
Wikipedia
it is just marketing video .
Xdrive or Quattro are just marketing terms. Depending on drivetrain Layout it can be a very cheap and nasty system, something mediocre or even a really good one.
Does the 5 series 530d msport have a good xdrive?
Yeah, when talking about audi quattros. There are 2 types - haldex and torsen. Haldex is the weaker option, torsen is the good one. I'd suggest you read a little about them instead of me writing a long paragraph about them 😂
@@luckgrip252There is the Quattro Ultra..
Is the xdrive on e90 lci the same? Also is it always 60 to rear and 40 to front axel or it is 100 to rear and when needed it transfers to the front axel?
this i want to know to
40 front 60 rear. Over 100MPH its strictly rear wheel and can vary depending on traction.
@@boggerson MPH.
@@boggerson UA-cam notifications pop up on my phone home screen, makes it easy to keep up.
What about Car weight?is it 50/50? car weight?
are all x5’s All wheel drive? I bought used bmw x5 2007 4.8K V8, im wondering where to activate to 4x4.
Yes, 2007 BMW X5's are all-wheel drive. You do not need to activate anything, your all-wheel drive system is active all the time!
of course the mustang lover would think awd is activatable smh
In awd which tire will engaged mostly, front wheel or rear wheel??
Rear
I believe it will normally send 60% power to the rear and 40% to the front.
It’s rear drive bias as opposed to say an Audi A4 which is front drive bias
Theres been a few bmw with xdrive spinning out randomly...not sure the systems all that great
langra man bullshit
@@Jwdude123 all true especially the x4m
***XDrive transfer case in BMW's are known to malfunction and cause stuttering under load, around 10-15k to replace I was quoted before just bypassing transfer case through ODB2 port. Get a RWD and avoid XDrive models***
I agree. If you don't have an even wheel setup, and have an offset wheels, then expect problems. Especially if the diameter of the front and rear wheels are more of a difference than 2%. Mine was stuttering and causing the transfer case to malfunction. So I used xdelete.
Great
Subaru awd ?
I heard that m235i xdrive has awd overheating problems when on track. Is it true?
sdgsdgsdg54 yes. XDrive is crap stay away from it. If you really want all wheel drive get Quattro four by four.
@@ArcolaBridge quattro and xdrive are equaly bad. non of them are good AWD systems compared to stuff like subaru. but yeah stay away from x drive on track cars.
@@rampage3337 Quattro is not all wheel drive system. Quattro is an all mechanical 4 by 4 system. Subaru attempted to make a cheap knockoff version of Quattro but it sucks. Quattro is the only true 4 by 4 car.
Hay
You cannot "individually" control each wheels torque with open differentials it's just front or rear, it only works with limited slip differentials and not every single BMW ever made including base models have limited slips
Giovanni it does though. I was playing with the xdrive system in the snow with an x3 I drive. You could see it adjusting the power to individual wheels. I suspect it doesn't it by applying brakes to the slipping wheel which in turn transfers power to the none slipping wheels.
bjswimmer2003 yes the system uses the cars brakes
@@brandonbentley8532 And so does the system on the Subaru....that's why these days you need to change the smaller brake pads and disks in the rear than those of the front.
good that we have people like you... BMW made this all up.
wonder if this can be used with 2jz setup
even better n55
@@Bonkatronicks Hell no... nowhere near the reliability or power output of 2jz. Besides how can u even compare cast iron sealed cylinder block to a aluminum plastic crap BMW produces lol.
@@spoke1183 stock 2j is 250hp n55 is 300hp stock sleeves are just good if not better than a cast iron block not hating on 2j love em but 55 would pair better with x drive than a 2jz unless you have after market gear wich is still a guess on it working with the 2jz
@@Bonkatronicks That makes sense but don't matter how much the stock output of an engine is. n55 isn't even tough build compared to n54. Personally id rather have n54 if your running stock or modding. Bmw switched to n55 and single turbro for overall reliability since n54 models had lots of issues with twin turbos rattling, all other bunch of issues non engine but other components going bad related. However they improved all that within n55 models but lowered quality of engine it self with cheaper internal components.
Probably. But would most likely need some sort of fabrication.
4 years ago they probably have it mastered by now
It been great since day one what you mean
@@reggiecam8243 the video said that it consumes fuel lol
xDrive is fine, but as a car owner I would appreciate to have option to disable that in menu.
All you need is a flash tool and you can completely disable the front diff.
Lol WHY
@@cop2506 not for doughnuts copper LOL
This system Is better than nothing
bmw x5 is the best suv period!!!!!

i prefer car having spare-tire hanging on cargo-door-exterior.
Tyres make that car look sooooo good
how can xdrive adjust the power of every single wheel? i think it adjusts the whole axis
Иван Иванов I would imagine this is why you are not a BMW engineer, as they are INCREDIBLY creative and forward thinking! It doesn’t truly take much imagination to realize it wouldn’t be impossible to get two wheels to turn at different speeds even though they are on the same axel. Besides...if it didn’t actually work that way...do you really think they would claim it does? I mean, it’s not like they could get away with lying about it! Besides, it’s very similar to limited slip differential, which my car has. If one wheel loses traction it sends more power to the one that can handle it, especially made for cornering in track cars. Google it...you’ll be amazed.
Then the electronic diff comes to the game, hydraulic clutches left and right. Programming that system is the secret, not how the system works.
Most axles have a differential between them so one side of the axle spins faster or slower usually in turns. In racing, (drag racing in particular) both sides spin together at the same speed. Commonly known as posi- traction. I'm surprised you didn't know that.
Иван Иванов sub to me and i make better videos than logan paul
Considering that only the M cars have limited slip rear differential there is something terribly wrong with this bullshit advertisement, haha... milliseconds my ass... I will be in the ditch if I trust their stupid stability control in the snow and ice... You don't have to be an engineer to smell the bullshit in BMW marketing... would the BMW lie to us you may ask.... They did and they got caught so many times with stupid shit... Are you seriously that naive? I owned 7 BMW high performance cars in the last 10 years and I can tell you that even though their cars are mostly awesome, their marketing department is full of shit! :))))
Looks great. Pity it doesn't work in practice. My new xDrive X3 is fine in the wet but slides around like butter in a frying pan if there's a tiny bit of snow. The steering wheel literally appears to have no effect on the direction it goes in.
Which winter tyres do you use? I put Dunlop Wintersport M3 tyres on mine which got me up hills with sheet ice in a RWD BMW, not had any problems on snow (only about 3 inches of snow) or ice this winter
You obviously have a traction issue as s result of your tires. Nothing to do with the xDrive.
I’ve driven lots of cars and the electronic clutch regulating the xDrive is a work of art.
We have long and very cold winters here, and with a good set of tires you will have the safest and most enjoyable driving experience on the ice and snow
Operator error.
so YOU cheaped-out on winter tires and this is BMW's fault?
@@TheComputec Correct. In the same circumstances I’ve run a Lexus RX and BMW 3 Series X-drive. They worked great. X3 didn’t.
It's lame they can develop this, but not get rid of fake exhaust.
that's audi and mercedes

Is that a BMW Pacifica? 👁👁
x drive is a pain in the ass to work on.
Hacker07Gaming and it sucks compared to quattro
Transfer box, common problem on all bmw x drives, wish id have known before getting one, although mines been ok so far
Ive replaced the actuator, not a terrible job on my e90, the water pump and thermostat job was far more of a pain...if your transmission and engine are good the only thing that really fails is the actuator that sends the drive to the front...
So its 4WD, it does the exact same
virgine olive No, it is intelligent AWD which means the wheels with no traction. For example, the rear wheels have no traction, so the power is transmitted to the front wheels and vice versa.
Edit: I was wrong, it is ALMOST like 4WD because it has a kind of transfer case.
Difference is 4wd has a locking dif in the front awd doesn’t
Put your 4WD car into 4wd mode and drive around town and you will see why AWD is optimal for driving on "roads" with mixed surface grip and 4WD is suited for more extreme conditions. That's why 4WD is selectable (on off low ratio/high ratio) because it is horrible to drive around town in 4WD mode and chews through fuel
The video explains this... They are two distinct optimized systems and you should choose the system that suits your expected needs
When you see your car with a beautiful CGI 🙂🙃 F31 gang where are you?
Sounds like a Haldex system to me.
Lazaro Carreiro sub to me and i make better videos than logan paul
haldex my ass. xDrive is permanent 4wd 60/40 and it sends more power to each wheel when neccesarry
@@dimizavar no it apply brakes
Xdrive is capable of sending 100% power to the rear wheels, Haldex is not.
Crashed the e90 (rwd) because of a f*cking curve
Subaru still better awd system
So much saltiness.. from people who could never even afford a BMW.. go home.. smh
Lol sure
If all this is true then why would you ever need a LSD?
becaus of acceleration in straight lines and maximal grip exiting corners
Ughh, i drive BMW because oversteering is life. New x-drive BMW, no thanks!
Oversteering is feasible. BMW even promotes it to be rear wheel focused. My 535 xd made nice donuts at the supermarket parking ;)

on snowy-road,oversteer can make wheel-rim hit pedestrian-pavement then damaging wheel-rim

correction:'steering-tie-rod may deteriorate faster' should have been 'steering-tie-rod may loosening faster'
Just get sDrive then...
hondas vectoring still better
You wish :)))
If you actually want all wheel drive you should get Quattro four by four.
True
ArcolaBridge sub to me and i make better videos than logan paul
ArcolaBridge not 100% dude
Quattro is garbage. Drove a 2019 A4 for a day and spun out on the highway due to a small snow patch.
Which BMW models is the audi quattro 4x4 system available on?
Please Don't answer
Basically what Mitsubishi did over a decade ago but this isn't as good.
Imagine thinking anything Mitsubishi has ever done on a regular model car is as good as BMW. Mitsubishis are the fucking biggest piles of trash.
@@saganworshipper6062 they're both trash when it comes to reliability, but the bmw is classier.
I dont like it, why the hell do want four wheel drive on a bmw ? Its stupid totally unnecessary
William Wallace talk to me when you’re in a snow on a rear wheel bmw hahahaha
EqualsDeath I drive a RWD 535i through snow and it behaves extremely well. Don’t drive like a moron and you’ll be fine.
Ando Rexurix yeah as long as it’s flat but it’s a little dicey on a hill.
@@thetechlibrarian not realy. it's mostly that our goverments are retarded and have dumb ides about how road safty works. so most people never get tought how to drive fast and how to drift cars. that means that they are not comfortable with theyr cars and they don't know how to react when a car is slipping. i was able to drive a e46 325i with bald summer tires in the snow just fine. but im allso a trained truck driver so i have knowledge about how to keep my car moving and what to do in slippery conditions. i will agree with you that hill starts and such are tricky but a decent pair of winter tires and there should not be mutch problem with RWD vs FWD.
@@rampage3337 if you ever tried to race an xdrive car vs a rwd car in the snow you'd think different. Of course BMW'S traction control is great in the snow if you're from New England like me and have driven through snow your whole life, it'll get you there eventually but my xdrive car barrels through the snow and uphill with zero issues compared to my other rwd 328. Js. That said, xdrive is stupid if you don't live somewhere where it snows. No reason for it otherwise.
Low quality explanation.
this is bullshit! I see BMWs stuck on snowy overpasses all over the city all proudly displaying the logo "xDrive". The Cars suck & the drivers are the worst.
You guys are rich..U gotta be to own these cars..they always have problems..Very unreliable
X-crap, be vice, get Quattro.
Crapttro.
