Inside BMW's QUAD TURBO 3.0L Diesel Engine
In the world of diesel engines, we've seen a lot of interesting changes and trends throughout the years.
But, BMW took it a step further by introducing one of the weirdest diesel engines you'll ever hear of: a 3.0L inline six diesel with not just one, not two, not three, but four turbos.
So, today let's take a dive into the BMW B57 quad turbo engine and see what it's all about.

BMW realized turbos were getting too reliable so they added more to increase the chances of failure. 💪
M57 turbos don't usually have problems. Ran mine stock for 150,000 miles before I upgraded. Sold them for $500.

S58: *what's unreliable?*
That's quite fun to hear "3L is a small engine" because in Europe, that's very very big for an engine, even a 2L engine is considered sporty
Yes in todays standard for sure. But back then 2l was considered nothing
I love my 2L BMW 1 series diesel and the 2.5L 3 series I have.
That sounds amazing and terrifying to own outside of warranty
Not really, it's a very simple system. I've seen 4.0L diesel engines in the agriculture in order power small farm equipment.
@@LBZDreamerThe turbos will be the first thing to fail. And there’s 4 of them.
I absolutely shudder at the thought of a 2nd and 3rd owner of one of these things.
Probably very on point.
It is, thankfully there are only a few of them on the road 😅
Could you imagine a 7 series achieving 40mpg? That would be killer.
My 20 yo 5 series 20d gets that on the highway
Joe Achilles achieved 67mpg when he drove from London to Madrid in the -16 730d. There is a video about it on KZhead.
US spec bmw 740 Ld gets that stock
@@peto22 True... i watched it... that was simply insane
I get 50mpg with my 10yo 3serie 20d
I really wonder how reliable these new high-output designs will be in the long run. The new 3.0 Duramax is especially interesting because it uses an aluminum block. Then again, the diesel engine that powered the Soviet T-34 tank also had an aluminum block and it lasted a while....
First hand experience with the 3.0 Duramax. It's a joke. Definitely stick with the normal Duramax. Never thought GM would make an inline 6 harder to work on than a v8
@@alainaguilar9938 yea ive heard its pretty ass to work on
T34 engine didn't last long
@@JohnSmith-lf4beby lasted a while I meant stayed in production...... Soviet engines were crap in general....
These modular engines i think uses same type of crankshaft which are capable of handling 1000hp
Honestly the tuned power numbers were not that bad considering it's a 3.0 liter motor with small turbos. Honestly think that's pretty good overall.
Thanks for the video! Currently driving a ‘23 X5 M50d - bought it just before the LCI to get this engine - not disappointed at all! Feels more alive than the M40i Z4! Really a magnificent engine 👌🏻 In South Africa about 2/3 of BMWs are diesel - good power with great economy - it’s a pity they killed it off and all we have is the 30d with the sample hybrid system 😩
m50d smokes even on a 2022 car even the m40d smoked, idk
Well. Belgium just saying FY to diesels with low emission zones... too bad
I cant complain about my twin turbo s55 its a monster
One of my colleagues from university has a mechanic shop in which he does mostly BMW's. This 2017 750Ld came in the shop with some turbo problems. The quirky thing about it was that it was an ex-government car and it came with a 40 horsepower bump from factory. I got chauffered around on a little test drive in the most important place in that car, the rear right seat. Even with its faulty turbos, it glued me to seat and was quiet all the way up to the redline.
I drive an m550d estate. The torque never gets old, this engine is a masterpiece
This "masterpiece" has been cancelled long time ago. 😂
@@Enko063 that's what EU regulations to do modern engines that are designed for performance
@@koiflichrl1974 Also it has been unreliable. God help for second and third owner. 😂
I heard about this engine couple months ago, and I was waiting for someone to make a comprehensive video, so thank you!!
One thing that B57 make happy is it share simillar block construction to B58. So BMW make both diesel and gasoline engine on simillar cylinder block. And diesel usually run with higher boost from the factory. Thats make B58 very strong because the block has same standard as B57 does.
I've been longing for a B57 deep dive video thanks mate
This is the stuff I need to catch up on modern engines. I've ignored it for over a decade and there is a LOT to learn now.
The M57 with two CP3's and a couple of Tim's turbos = 550-600hp, 800trq
You got any experience with tims turbos? I have a m57 in a 335d and been looking at Tim’s turbos stage 3 but I don’t know anyone whos ran them.
dual fuelers in a m57? What size injectors is it running?
@@LBZDreamer stock. The injectors are not the limiting factor
@@LBZDreamer Stock.,.They flow pretty well.
Driving my deleted M57 now! Love it!
Thx, please can you do one on the N57-series?
Finally, been waiting for this engine, thx!
Diesel is the future and answer to the automotive industry. Not electric
I agree! What people don’t understand is that a new diesel with emissions systems are net 0 emissions.
Too bad Dieselgate happened
No. I'm also a big petrolhead, but in terms of Environment an electric car is already way better than a Diesel engine. I don't like this fact, but therefore this fact should not be denied.
@@maxwagner5502you are completely wrong.

Imagine these turbos failing 😂
Just buy another superior turbo compared to this - what's so hard about that?
@@baoquoc3710you honestly think it’s that easy to just find another “superior” turbo for an engine that was designed with its own one off setup like this that will bolt right up huh? 🤦🏼♂️
If one fails you have 3 more left its not that big of a deal.
@@hairtrigger2438 what kind of turbos that's one-off? Just a snail spinning boy that pushing air into the na block and a failure turbo didn't made it the end of the world, do you have to complicated your thought about it being something that so out of ordinary?
I bet that would be really fun to work on when the time comes all of that in a not real big engine compartment
Friend of mine has a 2021 M50d. An absolute beast of a thing. It just keeps pulling and pulling. He's a sucker for punishment though as he used to own a triple-turbo version (2014 I think) which blew all 3 turbos and wrecked the engine
6:28 the 10 injections per engine cycle thing is a staple of modern common rail direct injection diesels, basically fuel is injected gradually instead of all at once, which improves power, torque, performance when cold and emissions. It was actually pioneered by FIAT who patented the JTD system (jet turbodiesel) which later evolved into JTDm/Multijet and later still into Multijet 2 and 3, which is used on FIAT group (FIAT, Lancia, Maserati, Alfa Romeo, Jeep and so on) diesels up to this day. This system was sold by Bosch and formed the basis for all contemporary crdi diesel engines including VW group's TDi, Peugeot group HDi and BlueHDi and BMW and Mercedes diesels
Alotta guys prefer the single turbo 30d models (530d, 730d). This is because there's aftermarket parts available like turbos that can increase power.
Would love one for retrofit ! Minus all the exhaust crap !!
I dd a older bmw m57 i6 twinturbo it's tuned to about 400hp 600tq 40mpg. I've been very happy with it runs mid 12s looks good and cheap to run
If this and the B58 share blocks then why not put a dipstick on the B58 too then!?
You can if you want to. There actually is a machined dipstick hole at the bottom of the block. On the stock B48 and B58, it is used instead as part of the crank-case ventilation system, filled instead with a fitting for vent hoses. I’m sure there is a way to run a catch can instead and run a dipstick The newer V8s and V12s have dipsticks
Love this channel. Lot of great information. Thanks for the great content cheers from Canada 🍻
Could make an interesting option for a supercar motor built-in someone's garage using a Porsche Trans axel And you take off a bunch of those emissions standards And slightly upscale the turbos that are built into it I mean sure you will lose some miles per gallon Going to somewhere about the thirty's range But I think that would be just fine Although you would just need a trans that is built to handle the amount of torque
I drive this engine daily in g31 2018 m550d, it is like nothing I have ever driven, such power.
Awesome another BMW engine to breakdown every week
Neighbor has that power out of a 2011 3.0 diesel 335D. Egr delete and tune. At 85mph we were getting 54mpg.
Their naming system make's complete sense and gives most of general information needed on the equipment and design.. Whats the issue
Can we put in 4 hybrid turbo's?
"Just a small 3 litre."
I wonder what it would be like for marine applications. How well it would be for a 400 HP outboard diesel
Once someone has a quality delete system for all that horrible emissions equipment, I bet those could make massive amounts of reliable hp and torque
This would give scotty kilmer a stroke! Endless money pits!😂
Only a moron would even watch Scotty !
BMW's Tuner ALPINA still makes the Quad turbo diesel engine for the XD3 and XD4(Performance diesel versions of the X3 and X4). They have made an even more powerful tri turbo diesel engine which goes into the 400 Horsepower range and can be found on the D5.
i think an good comparison is the eaa288 2.o bitdi . 240hp 500nm of torque and a good fuel milage of 6 liter in a station wagon with a 7 spd dsg and 1650kg weight
about the after market power upgrades, you can get 530hp and about 830NM from that engine with a stage1 a stage 2 where you remove the dpf would get you about 570 and almost 900NM. However that engine and its predecessor were made to make a diesel engine "feel" like a petrol engine. I personaly have the f10 m550d and its running with a stage 2 490hp 872NM for 4 years without problems though I removed the AGR, "Drallklappen" as we call them in German and did a few other tweaks to make the engine last longer. But after market wise you cant upgrade the Turbo chargers as far as I know due to the architectur of the blowing system I think am not so sure about that topic tbh...
2:00 From my knowledge the b57 did not have 3 turbos, only the n57 did
There is a B57 variant with 3 turbos- in the Alpina D5.
@@kaismueller Seems that you are right. Thanks for the info
I own 550d, g30 with simple ecu and gearbox tune and i achieved 3.5 sec 0-60 and 11.6 sec on 1/4 mile. Car is fantastic. 190000 km on clock and everything fine
Mossellman turbos or what its called offers upgraded turbos for the b57. I can imagine it to be a pain to install but still there are options, and those who rly want to reach 500hp will be able to do it.
Would love to see this engine in a 4x4 ute
“Four turbos” *five pictures of turbos on screen*
I can only imagine what this thing cost.
I believe you can still get them from Alpina because they don’t make a whole lot of cars a year but only in Europe
Aluminum block + 4 turbos = best reliability
please do the triple turbo next, the previous generation
Would be cool to see a petrol version of this engine put in a light weight sports car.
Would love to see someone build one with no restrictions maybe large single or one large and one medium turbo set up....
Thats what the n57 and m57 lineup is for. Been a few people now making 1200nm and 550+hp
Definitely a fascinating motor in it's own right. One would think that the CO2 emissions would be relatively low given its impressive fuel economy.
That is a good logical thought. However, anything that burns creates CO2. Perhaps the CO2 per Mile would more accurately fit Your comment. Logical thinking! 5:47
*it comes down to particulates
Love turbo diesel schemes
At the mechanic getting a turbo done. "Yea you might as well do them all so we don't have to pull the engine 4 different times.😂
let me know what its like to fix a head gasket on this when its out of warranty
Years ago (2012) I talked with a BMW tech about the N57D30 (Tri-Turbo) engine about its reliability: "Usually the first customer of a car with that engine is a lessee, so he/she does not care about repairs as the car is sold after about two years. But beware if you're the 2nd or 3rd owner - even minor repairs are expensive because we have to remove the engine from the car as everything is so crammed inside the engine bay!" (and we're not even talking about BMW OEM spare part and labor prices...).
This thing is made to blast the Autobahn. Doing high speed for long time at low revs without having to stop for fuel. I drove one of these from Stuttgart to Munich and just one and a half half hour.
A chipped N57D30T1 will knock out 420bhp with an intercooler and a egr delete, nevermind downpipe and bigger Turbos/injectors... And if the weak point torque wise of the package was the ZF 8HP700, why didn't they use the HP900 used by Rolls Royce?
The gearbox can take 1000nm with XHP tune no problem. Might have to change the ATF more often tho.
Imagine this engine swapped in BMW 3er and AWD. That would be a killer.
Really nice video but I have a sugestion for you. I for one am an European so I don t really know what the torque figures are translated to nm. Maybe you could add metric calculation in your videos as well. As in HP to kw, ft-lb to Nm and mpg to l/100km. Would make it a lot more enjoyable to watch for me. Otherwise great content!
Not meant for tuning. This engine meant to achieve the v8-v10 powerbands from the '90s and '00s with smaller displacement. The only reason this engine is complicated on this level because it was trying to survive the Euro 6d and in the meantime it became a ticking time bomb. At 10+ years old and over 200k miles these will be the most unreliable, most expensive things to own ever.
I want to see a triple turbo setup. 3 different sizes. Little to big. So you get response big power up top and everything in between. I’m sure they could do it with their new electronic waste gates. They can make the turbos do anything they want with software.
BMW did that about ten years ago with the N57D30 Tri-turbo
I own a 2017 BMW 750d xdrive for this engine alone. I freakin' love it.
tbh, bmw i6 diesels have the best turbo transience of any boosted motor ive ever driven. With the newer ones, power is near instant and there is borderline no spool time. They feel like low rpm v8's
n57 got 3 turbos, b57 4 turbos🤩🤩
Question does anyone know the dry weight of the N57 or the B57 diesel engines??
Is that American mpg?
Im sorry, let me get this straight real quick: - 4 spooly bois - 41 mpg - Compact 3.0L - 400hp - 560lb-ft or torque - 4 spooly bois (have i said that already?) Why hasnt someone put this damn thing in a miata yet?
I see this and I just imagine a new engine for the next m3/m4 platforms with 4 turbos and 900HP and 3 high pressure fuel pump
The bmw M67 was a monster diesel engine and super reliable
5:17 WOW a BMW with turn signals??!!
That 750d has the same ZF trans as a dodge demon, no? Shouldn’t it handle torque just fine?
McChip tuned this engine to 515hp. There are two youtube videos, one of the 5 series and the other of the 7 series
You would think with hydrogen on the brink of being introduced perhaps a separate tank of HHO gas could be injected into the fuel system of this power beast to make it comply with emissions. There are some papers showing hydrogen stratified with diesel fuel making for very minimal emissions.
Sir... That was 5 you put up there😂
And in the real world the Euro 6 engines are finding all of these emission gimmicks are being deleted by garages just to run by 60k miles, they just dont work for long enough.
Search 'M2 50d' , a swapped M2 in South Africa making 600hp and 1000Nm+, running on watermeth and Nitrous.
My 2011 335d M57 sequential turbo is a ton of fun. Quick but very expensive to maintain. I fear the infamous #1 main bearing failure though. My wife’s 2006 MB320 CDI OM648 is much more reliable. It can be “hot-rodded” to 300 hp/550 lb/ft of torque at the wheels while getting 40 mpgs.
CDI for 2000 the guy I bought it from here to his car had seven hundred thousand miles Annie drives it all across America currently
I have an 09 with the m57 with emissions equipped. Could you tell me the possible unscheduled maintenance on those cars so im ready to pour a little cash into it. Right now im in the process of replacing the thermostat, and swirl flaps delete. I saw a little leak from the small oil line from the small turbo. And also saw the vacuum lines are becoming brittle that also needs to be replaced. Overall the car runs excellent. I minus test all the glow plugs too before winter comes.
@@shadowsiren3058. Couple of more things, examine the harmonic/dampener balancer very closely. If it is bad, it will take out the main bearings pretty quickly. Look for cracks in the rubber portion. If your AC quits and the charging system light comes on, it is about to leave the “chat” if it hadn’t already done so. And lastly, change the oil/filter every 5K miles. The 09s and 10s appear to have less problems than the 11s do. I think BMW sold about 10K of the 2011s versus maybe 2,000 for 2009 and 2010s combined. Since there are about 5Xs of the 2011s may explain the higher bearing failures. Some speculate that BMW may have received some faulty main bearings. Fun cars to drive though. Look up Santger Performance Development (SPD) on KZhead. He has a 335d (probably 800+ hp) that he drives to the drag strip, runs 9s and drives it home.
@@shadowsiren3058harmonic balancer is something to look out for. If it has any cracks change it
Your 335d has a version of the M57 not prone to that issue. There is nothing infamous about it. Completely irrelevant to your e90 335d
Tou should talk about the Mitsubishi 41m4
I’ll bet with an emissions delete and upgraded turbos this thing would easily see 1000hp
Check out Darkside Diesel
Reliability minus 400%
World record for a 3 liter BMW diesel is held by a Romanian in the low 8s. He uses the iron block M57, the N57 that has the bagillion turbos is made out of glass and will fail even at stock power levels.😊
@@rinkk8126farthest thing from the truth lmao
I´m driving one of these and it´s great. Mostly driving calm. But when i need ist, the Power is magnicifent.
tuners like g power or abt always keep their power outputs low for reliability. So normal Tuners push these engines to over 500hp with 1000nm of torque.
By removing the DPF you could improve the performance by a mile. My friend did that to another Diesel BMW and "found" extra 116HP xd
BMW came with 50d 3 and 4 turbo diesel engines way before Audi’s SQ7. Great video nonetheless.
With a deisel putting out that kind of torque and horse power I would be concerned about the aluminum block and the main bearings. Should have used iron block
OMG they used Piezoelectric injectors again, like in my N54 335i.Have they not learned their lesson from the late mid 2000s. Interesting engine though im sure the torque is absolutely effortless.
Was 3, now 4, just evolution
G05 X5 M50d owner - god, I love this quad turbo engine. Instant power and so much torque! A rare machine now
At 100tkm prepare for Rod bearing change!! Then around 130-150tkm small turbos… then at 170tkm transfercase will go.. not talking about the front weak ass driveshafts…
yk since everything is module then it’s (technically) possible to slap those 4 turbos to a B58. Besides the limited space you’d have what’s stopping someone from doing that
Sounds like highly expensive maintenance.
They're great stock, but don't tend to last very long with a tune sadly.
This engine must be so hot it actually melts just by turning it on
I hope that this b57 is better than the n57, because n57 have issues with bearings, oil pump and chains, mainly the high hp versions
Another beast, and b57 is the right reason why b58 is so good. If bmw applied the latest iteration of vanos system, b57 would have get near 600bhp reliably

@@R3YNZ it has issues with broken oilpumps that lead to spun bearings and also suffers from (somewhat rare) timing chain failure. The N57 in the E9x 325d and 330d is the most reliable variant.
I think you got something wrong with the emissions regulation. It's not correct that they sacrified due to the fact that the engine is emitting more than 95g of CO2 per km. In fact most (larger) engines don't. And it is allowed to produce such engines anyway. In fact what counts in Europe are the over all emissions of the brands fleet. If your company fails to meet the emission goals then your company has to pay penalties. So many companies sacrified their larger engines - especially those which sold worst. And those two facts came together for the x50d or the 760i. Both emitted a lot of CO2 AND weren't sold very often. Combined with even stricter upcoming emission standards (Euro 7) that marked the end for this fascinating engine. Funfact: when I bought my G31 (btw you forgot this model in the lineup ;)) I was struggeling with myself which 6-cylinder diesel to choose. In the end I decided to go for the 530d as the 50d is faster in acceleration and that is about it. This only pro argument for me stood against higher maintanance cost, more parts that could fail, higher buying price and so on.
Wat about relayebility
i like M57 with bi-turbo and it has higer potencial and less parts to break
someone a madman, will refabricate the system with larger turbos built internals etc. im waiting on it
Everyone is talking about this thing ! Toss a giant single Turbo add more fuel and tune and you will have 500 hp with 700ftlbs of torque making all these big cars move beautifully
Pardon I small and One large turbo...
