The b58 has proven to be an amazing motor. I am excited for the S58 seeing that one in an X3M already made 750whp with just a tune and fuel!
In Belgium where i live just 3 streets further from my house someone own a X3M he lowered it and has done only decat downpipes and tune making 710 hp and 900 nm

Awesome breakdown of the differences. Now if only my 2023 Supra came with an S58 engine rather than the B58 :-)
There's a rumour there's indeed such a Supra in the works (S58 powered GRMN version). Supposed to come out in 2024. I don't know when we'll see the first confirmed details...
@@NoBrainerTalk wow I'll trade mine in for that if I could get a hold of one.
Wife has the b58 in her m40i and that engine is insane my last car had an s55 and I can’t tell the difference - insane engines
Wait so your telling me your can’t tell the difference between an last model s55 M3/m4 and a newer b58 regular turbo bmw ? That’s incredible but I highly doubt it . The s55 is much more superior to the b58 and as of now it’s even superior to the s58
@Justin Dir While I agree the S55 is superior to the latest B58 examples, how did you determine that the S55 > S58? Thus far I’ve heard/read the exact opposite.
@@JusZard oh boy...
@@JusZard not true the newest m3 would literally destroy the last gen in a race. It’s miles ahead of the last gen m3.
@@JusZard I had the same experience with J, honestly no disernable difference except for the DCT in the F82. The difference would show on track but not on daily driving within the speedlimit. (S55 and B58)
Man this is truly a great video explaining these engines. GREAT JOB!!!!!!!!
I love the detail of this video, great job!
This video is really straight to the point and the explanation is really easy to understand
I have an M3 xDrive and seeing this video was very amazing seeing the Engineering behind these wonderful engines
Very informative thank you! 🙏🏽
Great job. These new engines are incredible from what I've seen and read. Of course the S58 seems like it will be the really big power possibility in the tuning world to come. However the B58 is the leader in 6 cylinder technology from every day cars with exceptional engines. It has been tuned to 1000hp with more room to grow. The S58 I don't think has had as much of a chance to be tuned on as completely. Not that either engine has been explored anywhere near their potential. Considering even the much older N54 engine from the E9X and E8X as well as others from the 2006 to 2013 (or so) average car range (Not the "M" variants) even hasn't been explored as thoroughly as it could be. Yet it is being run at huge power increases and boost pressures by thousands of people seeking big reliable power for the least buck. Exciting stuff from the Germans these days. A rare bright spot in this insane world we are struggling to live free in these days.
Indeed I think the much larger number of B58 engines across the many platforms and the more "simple" design compared to the S58 is leading to much more customisation and exploration of the B58 potential.
@@NoBrainerTalk how about reliability? Who wins? B58 vs S58? Gonna be deciding factor for me lol…im debating if I should get supra or m3. Im planning keeping car forever and leaving it stock…hmmm…??
@@channelgreen5949 The B58 has proven its reliability, the S58 is too new to say. I would say it's unlikely for the S58 to exceed the B58's reliability, they could possibly end up being equally reliable. I would say a stock M3 x-drive is more likely to be a forever car than a stock A90 Supra (for me personally) although I'm not a fan of the M3's front bumper design (only because it doesn't feel like a BMW)...
@@NoBrainerTalk so m3 x drive over regular m3 competition? why?
@@channelgreen5949 500+ hp on two small patches of tire, is so easy to lose traction and grip. Xdrive is not only a benefit for straight line shenanigans (0-60 times, quarter mile times, etc) but also around a track, coming out of corners, etc. It's so much more confidence boosting to have the xdrive system. I know that "proper" BMWs or maybe "proper" sports cars were once thought to be RWD only, but I think that time has gone. It's now all about the experience, and BMW's xdrive system in the G80 M3 let's the car and the driver achieve their full potential. I don't know if in 10 or 20 or 30 years down the line, which one will hold its value better, but If I could go back in time, I would go xdrive on my M140i too. Just my opinion.. :)
Incredible information! Thank you so much!!
Was very interesting video to watch. Thanks 👍
Great video and very informative!
Straight, to the point, concise information. Great stuff.
A small suggestion, please align the topic with the image, like at one point, s58 (left) & b58 (right) are shown, but, you’ve start explaining the later first. Causes some eye wandering around the screen as general tendency while comparing is to move left to right.
Great video. Thanks for the information!
Cool thanks for posting 👍
Amazing video, thanks
These videos are so cool! Appreciate all this info and the simple way it’s explained
Great video, very informative! Would love to see more videos like this for other BMW engines like the S63 for instance 🤞
A video about the N63Tu would be informative too! 👍
Great video. I think it's safe to say that BMW really knocked it out of the park when they built these engines. Both can be tuned to make Outrageous power numbers. Though. Its clear if you push both of these motors the the limits the S58 would hold up better.
Underrated channel man! Good luck
Thank you!
It's interesting to note that the S58 reverts to a bore/stroke ratio very similar to the N54, N55 and S55.
Great video!
M30 (The Big Six) engines on boost can easily make 400-500 hp with just ARP Studs and MLS Gasket on stock internals. BMW engines back in the 80's were built strong and reliable.
Modern engines are all about making all that performance reliably, and keeping emissions low.
Incredible video !
Lovely guitar intro 🔥🎸
Great video. Thank you.
I appreciate this video explanation.
S engine =stands for M sport for M models, P engine= stands for M power for racing engined models.
The B58 has been the benchmark in 6cyl straight 6 technology. Hope the S58 will live up to its robust (and rugged) performance legacy!
Great video! You should do one on the differences between bb58tu (high power version) in 40i variants, and b58tu01 in Supra grs, Not sure if you’ve already done this
Hi, there is certainly some demand on this channel for more information / comparison of the BMW versions with the Toyota versions (2020 and 2021). I'll see what I can do.
Lower the volume of the background music. It’s hard to hear you!! Content is superb. Don’t let it get drowned out.
Is the class above T usually reserved for the race cars like the GT Class or F1?
Very informative and interesting. Thanks!
The B58 was already comparable to a 2JZ; the S58 is likely exceed the 2JZGTE at this point. Not to mention the number of mods needed to make the same power as a 2JZ....in fact, the B58 has the 2JZ beat there already.
The n54 was already better than a 2JZ. 2JZ's had a shit powerband by comparison and you didn't get 500+hp out of them without new internals unless you wanted a con rod to shoot a hole in the block.
2JZ's have been seriously overrated by a modding community that has stuck with them for decades and produced many 1000hp+ cars with it, but when they show you the car they never tell you that the only thing in that engine that is still stock is the valve cover. The main reason why the 2JZ is so popular for these high performance projects when compared to other engines just as good or better is the massive amount of aftermarket options, modding a 2JZ is easy because there are bolt on kits for everything.
@@BigUriel new internals after 500hp? Idk where you got this info but stock 2J blocks are good for over 800, current record is over 1000whp, even 1JZs can safely make over 500whp with just a big turbo and good fueling. I don't disagree that the B58 has surpassed the 2JZ and the N54 is on par with it, but don't underestimate 2JZs because they really are a technical marvel, especially considering they came out 25 years ago!
@@BigUriel The 2JZGTE engine has an incredible and fun powerband - explosive power that no OEM manufacture would ever sell to a customer. And 2JZGTEs have withstood 700+whp on stock internals for extended periods of abuse. Not too many engines from the 90s that can compare to 2JZ competition.
@@755hp I saw the disagreement over the 2JZ, I'm not an engine builder, but I've become interested in the topic. Would it be wiser to build out the 2JZ's internals before tuning for 600hp+? Is it the physical design of the 2JZ that makes it so effective, or is it the metallurgy? Does it have suitable stock fuel delivery to support 600hp+?
Thanks, Mike.
@@MrSbeve is it a matter of design or metallurgy? I have been told the cast iron blocks can take tremendous pressure. I also heard the head and deck design of the 2JZ was very good. Do you think it's a good idea to put new internals in a 2JZ before tuning for high power?
I think this engine is really the pivot point for BMW with actually designing an engine well from top to bottom … yes BMW always made very high performing motors but they weren’t always well designed. These engines are reliable and high performance, finally! Lol
Imagine if BMW made an updated version of the s38b38 engine for an m5. That displacement plus today's technology would be crazy.
Bmw just trying to prefect combustion engine. Still a ways to go but more impressive each one none the less
But excellent video.... Thanks for your reply....
Great video, please make one about the 2020 supra engine B58b30C (what does the C stand for?) vs 2021 supra engine. Many Thanks
Hi, The 2020 Supra engine is most likely a B58B30M1 whereas the 2021 Supra engine is most likely a B58B30O1. The main difference should be the turbo itself and the cylinder head. Actually I don't know what the "C" stands for, I would love to know too. I imagine it would designate it as a customer or export version, but this is just how I think of it.
great video! consider doing one on the n54, specifically the 335is’ n54 :)
Suggestion noted.
I wish more manufacturers made inline 6s. My all time favorite engine layout. Can't afford one yet. Lol
Old jeeps are inline 6 as well. I am a fan. Robust and balanced engines.
Do you think they fixed the crank hub though lol
The s58 is a b58, with less compression and a bigger turbo. The lower compression reduces the risk for detonation, it makes it less efficient, however it can make more power on 93 octane without detonating. The bigger turbo helps with power out the box. Considering this the b58 could do the same if the compression ratio was lowered and if tit had bigger turbos.
All of this tech and you can take a m20 and a turbo and make 400+ with good tuning. Not knocking it, it just crazy.
What a fantastic video. Deserved a Subscription and alert. Is it possible for you to do a B48 difference to B58?
Let me see what I can do...
@@NoBrainerTalk Fantastic man. I have an F30 with a B48 engine and with BMW doing its modular engines I am fascinated by how different the B48 petrol engine is to the B58 petrol and also the B47 engine. I understand these engines are very similar but can't understand how since the B48 is lower powered to the B58 and also uses different fuel to the B47.
@@tatendak Interesting points, I will keep these questions in mind.
As a retired mechanical engineer, I love this detail, well done. I have the 'basic' B58 in a 2019 440i with ?324? bhp. Although I'm content with mine, many owners improve output in various ways. Would you be able to offer any insight into engine components that would be at risk from output increases? For instance I've been offered a retune adding 40bhp and 80nm. Would this or greater increase overstress any standard engine components? Thanks in advance.
Hi, BMW offers the MPPSK (M-Performance Power and Sound Kit), which increases the B58 power output to around 360hp (essentially using a tune), so in essence this proves that the 1st gen B58 is able to produce 360hp without any detrimental effect on the components (all design safety margins should be applicable at the MPPSK output). Any power output below the MPPSK output is essentially underpowered (safety margins unnecessarily higher). This is the easy answer. The less easy answer is how much power can you safely extract out of the B58 without modification (aka the best stage 1 tune). Personally I am running a very modest 370hp stage 1 tune, not far above the MPPSK. I've been quite happy with it, and I'm confident the additional stress that the engine components may be subjected to is well within safety margins. There are many owners who after putting their cars on a dyno claim they had greater than stock hp to begin with (e.g. 350hp instead of 335hp), and that a stage 1 tune gave them in excess of 400hp. I personally don't know how true these claims are, as the dyno results can be inaccurate. My car was found with 335hp before the stage 1 tune (bang on what it should be), and the tune was not far off the BMW MPPSK tune. Many B58 owners have extensively modified their engines and extracted well above 450hp. Relatively very few tuned or modified engines have actually failed, indicating that there are very significant safety margins (this may be due to the modular design of the engine, sharing many components with other BMW engines, hence the design of components can tolerate an array of applications). The general fleet experience is still relatively low, meaning we don't know how the increased power output will affect long term reliability, but compared to the N55 the B58 engine benefits from significantly more advanced internals, so it should remain reliable even when tuned. Sorry for this long answer, just some thoughts... :)
The B58 doesn’t start getting into the danger zone until you’re over 650BHP
Can you do a comparison video between the B58TU (BMW cars) and the B58 that comes in the A90/A91 Supra?
I will consider it... :)
@@NoBrainerTalk I'd appreciate it.
Curiously the Supra used to be in the BMW online parts catalogues when it was first released, but now you can't seem to find data on it anywhere. It's almost like that data has been removed from public access because they don't want us to know how different, or how similar, the engine in the Supra is.
If I was a betting man I'd say a lot of Toyota fanboys would be upset after learning those "modifications" Toyota supposedly did to "improve" BMW's engine actually amount to like new plastic covers with a Toyota logo on them instead lol
@@BigUriel they had blueprints of both B58s with the Mk5 B58 vs the Z4 B58 in the mk5 supra forums and some people looked at both and tried seeing the differences. Its in the forums but dunno if you could still download/look at the blueprints or not.
Would like to see this comparison too

Is the s58 crankshaft snout detachable like the S55? Will the S58 suffer from crank hub slip like the S55?
The B58TU does not have a crankshaft snout if I'm not mistaken, and therefore if the S58 is loosely based on the B58TU, I would guess that the S58 will not have one either. Also it would make sense that BMW would address with the S58 engine one of the main issues plaguing the S55 engine, so I would be very surprised if the S58 suffered crank hub slip. Then again so much focus and attention is on emissions, that who knows what issues will plague the S58. There's no better way to reduce emissions than an engine that goes into limp mode all the time (joke)...
Looks like S58 were more heavy duty than b58, especially on cooling departement and lubrication system. Could be the block design were very similar to b58?
I think this is possibly how the S58 was born, they took the B58TU engine block as the starting point and adapted it for twin turbo.
I want to see a bmw engine with the S designation for Super 👀
i thought there is a S58B30O0 for the base m3/m4/x3m/x4m, and the comp is using the S58B30T0?
Hi, I don't think so. I believe there is no hardware changes between the "standard" engines and the competition package engines, it is just a tune. A change in designation implies hardware changes.
Sounds like the additional turbo maybe the cause of higher HP output. 🤔
A second turbo does contribute greatly to increase power I would say.
@@NoBrainerTalk Do you believe that we will be seeing an GRMN version of the Supra using the S58 motor?
@@2006chunming I've seen the rumours of course, but I don't know. Manual supra is now a reality and the rumours about S58 supra are from the same sources presumably so I wouldn't rule it out. But I personally find it hard to see the packaging and economic sense of this for Toyota...
could you do s55 vs s58?? great vids!!
I do want to, but I thought the subject was well covered on UA-cam already. :)
@@NoBrainerTalk quality, not quantity :) your vids are done waaaaay better :)
Both good engines, but I'm not a big fan that the oil filter housing was made a serviceable item requiring full assembly replacement every oil change due to shocking design flaws causing the filter inserts to seize and deteriorate inside.. Guess thanks to Toyota for this as BMW never had any filter problems in years ever..
Interesting note.
Brilliant video. Informative and clear. Just get a new microphone please!
Trust me, there is nothing wrong with his mic.
@@peterkukolik8402 his other videos are fine, but the sound in this one is very muddled and you hear "mic noises".
Not clear but which b58 designation for 2019 m240i? Believe it may be the same as the 2020 Supra before the 2021 Supra’s numbers were increased. It may be due to the larger turbo
No, the mk5 had a B58 with a 2 port integrated head(which the 2020 models came with)1st and then the 2021 model mk5s came with a 6 port traditional head B58 with a lower compression ratio. They have the same turbos coming from 21 to 20 so they more or less just increased the boost for the 21 is all.
The s code on the engine name must be for those that you find on the race track, right?🤔
The M-Division converts street car engines into engines intended for motor racing, so the "S" designation does indeed signify it is for racing. :)
Thanks he explanation. But my F32 Bj.2018 with 326HP has engine designation: B58B30A whats thies, for what is the A ? and than nothing
Hi, you have a B58B30M0, and at the engine identification area it is engraved with part number B58B30A. Please see my "How many variants" video, link below:
ua-cam.com/video/lwFH-5Pgv7o/v-deo.html
I hope everyone remembers the n54 was the first bmw engine to get the real twin turbo set up…
Hi just wanted to know what does the Engine code B58D means ? I ran a VIN decoder for my 2021 M340i and it showed engine as B58D. I’m guessing it’s the TU 382 hp?
Hi there. Yes, you are correct, the B58D means the B58TU that produces 382hp. It seems to make matters more complicated there is yet another way to refer to the engines in the illustrated parts catalogue:
B58B30M0 (technical manual) = B58B30A (engraved on engine) = B58 (IPC e.g RealOEM)
B58B30O1 = B58B30B = B58D
B58B30M1 = B58B30C = B58C
I seem to have cut that out of another video I made.. Hope this helps.
@@NoBrainerTalk hey thanks! Although driving this beast feels the 382 hp is also underrated. Typical bmw 🤣
@@NoBrainerTalk hey bro I had a question does the B58TU (high powered 382 hp) have an equal length pipe or unequal? For the engine sound
@@kunalmore5212 Hi, the exhaust pipe length will depend on the chassis, but these days with more resonators and GPF added, it can't be too short.
@@NoBrainerTalk so the 2021 M340i has equal length pipes then?
700 and 600 rwhp just with a down pipe and tune dang these motors crazy
I kind of miss the days when ///M motors were high strung bespoke engines, with completely different block and head castings. Engines like S38, Euro S50 and S54. They just felt more special. More memorable. Not something that was the same as what you'd find in a crossover or SUV, only yours just ran slightly more boost, or had a slightly larger turbo from the factory.
Agreed. The s55/8 are very impressive but don’t have the soul of the S54/S65
S65 and S85...can't sell my s65
Also difficult to replace once blown lol. Heaps of spares with the b58 with chassis write offs
call me weird but id love that m3/m4 deep hefty sound in my m140i , i’m fully straight pipe and stage3 600bhp yeah my car is fast and yeah it’s loud butttt when a m3/m4 with a exhaust goes past i can’t even hear my car anymore and i find it soooo aggressive … is there any method to make the b58 similar to the new s58 ? what makes the sound different if it’s the same base engine ?
I wouldn't say it's the same base engine. :) but I would say the double turbo configuration (double downpipe, double mid-pipe) is going to play a major role of how the S58 sounds compared to the single turbo (single downpipe, single mid-pipe) B58. Alot of sound engineering would have gone into tweaking the airflows from the turbo exhaust all the way to the backbox exhaust, the harmonics, the interferences, etc. Just a thought, I am certainly no expert on this.
@@NoBrainerTalk yeah that makes sense i guess not gona lie hahahaha , i might enquire with a engine specialist and see if i can get the b58 tweaked to a s58 level to achieve that deep sound ? just be different 🫡
@@marnzx1206 How a car sounds is majorly important, good luck!
did he mention the closed deck block design
You mean as a similarity?
B58TUO1 has a 10.2 compression ratio. Since you listed B58 power at 382 hp, that is the compression ratio it uses with that version :)
Hi there, this needs further research. The B58B30M1 and B58B30O1 have identical crankshaft and connecting rods, but they do have different pistons I believe due to using different piston rings and gudgeon pins. I'm not sure the difference in pistons changes the compression ratio, but I suppose it could be possible. I've just downloaded the spec sheet for the BMW G29 Z4 and 2021 Toyota Supra. The BMW technical specs document states the B58B30O1 has a compression ratio of 11:1 (285kw output) and the 2021 Toyota technical specs document states the B58B30O1 has a compression ratio of 10.2:1 (285kw output)! This is very interesting, because I'm not sure how the same engine model can have different compression ratio! The 10.2:1 compression ratio was used on the N55 engine, hopefully this is not where the confusion is coming from. Again, I think this needs further research, something is wrong somewhere (perhaps the BMW document has a typing error), or we've just uncovered something Toyota is doing to the engine! :)
@@NoBrainerTalk I think the original Supra with the 340hp engine has 11:1 ratio and the newer version has 10.2:1 (the original Supra engine isn't the O1 engine afaik - it has the integrated exhaust manifold, therefore M1 TU engine?) Anyway lower compression allows more boost and therefore power at the expense of efficiency, so I think it's a good start to assume all high output (285 kw) engines have the lower compression.
@@harbl2479 Yes indeed the original supra had B58B30M1 engine, and now it has the B58B30O1 engine. However in drag races with Z4, it seemed to produce more power than the BMW, and possibly this is only a Toyota tune, or it could be that Toyota modify the engines (tweak the engines) after delivery from BMW. There is certainly conflicting information for the O1 variant's compression ratio, but lower efficiency means higher emissions, and I believe the current priority/focus is on emissions (making me inclined to believe it might be 11:1 as per the BMW source material). This is a nice little mystery! :)
@@NoBrainerTalk If you fins out more, let me know :)
Im guessing Alpina is also using the S58?
Yes, the Alpina B3 uses the S58.
Good video.
But stone me way to complicated for me 😂

Please kill the music, some people don't have 20/20 hearing.
Got it. New videos either don't have music or the music is lower volume.
Interesting and good video, but the sound quality was quite poor, a bit quiet, muffled, and worse, at about1/2 through their are buffeting sounds which make it hard to hear you sometimes. Oh and the music is annoying.
Noted.
I like your video very much. I saw a little mistake in your video. The compression ratio for the B58TU is not 11.0 : 1 , it is 10.2 : 1. For A90 supra it is 11.0 : 1.
Hi there, the compression ratio of the 1st gen B58 and B58TU is 11.0:1, this is correct. The A90 and A91 Supra have a B58TU engine. The 10.2:1 compression ratio is for the N55, N54, S55, etc.
The s58 is the best inline 6 motor ever built. And that's coming from an f30 owner. I'd grab a g80 if I could justify the spending when my 340 already makes 600 hp. Just put so much time into it.....
Fuck, anyone wanna buy it? Lol
So the s58 has true dual turbos, and the B58 is technically one turbo fed by a smaller turbo piggy backed to call it twin scroll? I see why they do it. To limit turbo lag. But sooo expensive to replace if you ever have to. Yikes. Over engineered? It's fun to drive, though.
This was a great watch, nice job! These new M motors seem way too complicated. The number of separate control systems and ecu’s that must be coordinated is crazy! Just the way they have the high pressure fuel pumps running alone is too complicated lol
I’ll happily stick with my N/A I6 bmw motors until I am forced to go electric by the Feds ☠️
That’s like saying airplanes are way too complicated, I’ll take my donkey! 🤡
They are basically the same engine, the difference is wether to bolt on a single or twin turbo
The S58 is about 90% new compared to B58... I wouldn't say it's just a matter of adding an extra turbo, although I would certainly be curious if anyone has done that (changed the single twin scroll turbo of the B58 to a twin turbo).
@@NoBrainerTalk I think if someone did that, the B58 would be equal. Remember that the base B58 is likely about to handle over 750 hp stock
The S58 is also used by the Alpina B3.
Yes, I think you are correct.
No, it’s the B58TU. Just tuned.
@@huntermurray956 I disagree, based on Alpina website technical data for B3, the engine displacement is 2993cc (same as S58), compression ratio is 9.3:1 (same as S58), etc. I don't think it's a tuned B58TU, based on the stats, it's a full fat S58 in there. :) Probably even a tuned S58.
The S engines always have extra oil baffles, extra oil return and fuel return pickup.... So what confidence exactly does your B58 or N55 give you to take your "M(arketing) Performance" car to the track if it will starve for gas or oil in corners.
It's true that the S engines (M division engines) are motorsport orientated, and have enhanced and/or supplementary systems for prolonged operation at high power output and in high g manoeuvres. But the B58 engine is also found in sport orientated vehicles such as the Toyota Supra, indicating that whilst not specifically designed for motorsport purposes, has e.g. sufficient resilience to oil and fuel starvation to satisfy most sporty driving demands (including occasional track demands). The S58 and B58 are relatively young engines, and we are some time away from knowing how the engines will cope with repetitive track use. Chances are that S58 engines will cope better of course.

It seems this is an Alpina designation for the S58 engine they use in the B3. It comes with less hp (462hp vs 473hp of the standard S58) but with higher torque (700Nm vs 600Nm). Alpina uses the same turbocharger housings as the S58 but with new turbines. They've also apparently redesigned the air intakes, upgraded the ECU, installed a new exhaust with different particulate filter, and optimised engine cooling. I'm not sure it was worth making so many hardware changes as the difference could have been achieved with a custom tune.. But I've never driven a B3 so my opinion doesn't really matter...
@@NoBrainerTalk you said that the B after S58 is for Petrol, for what is V in this case?
@@Nikroncik Hi there, in this case I do not believe it's a BMW designation. BMW uses the following options for the second letter:
A = Petrol engine, transversal installation
B = Petrol engine, longitudinal installation
C = Diesel engine, transversal installation
D = Diesel engine, longitudinal installation
K = Petrol engine, transversal installation, rear
As you can see the Alpina modified S58 engine is still a "B" so replacing this with a "V" would be an Alpina decision (I suppose so that the engines do not get mixed up at the BMW factory, when Aplina ships the modified S58 for installation into a B3). It probably does stand for something internally at Alpina, but it would no longer be following the BMW standard for engine designations. Sorry I can't be more helpful..
@@NoBrainerTalk Hi, thanks for your answer. Picking up an Alpina B3 in 2 days, will ask the BMW dealer if he knows if that V is only for Alpina :) if I will not forget ☺️
@@Nikroncik I'm jealous, that's a great car! Yes, please let us know if you find out!
I got 2021 M340i and it burning engine oil after 6500 miles. Anyone know what happened on this or got the same?
That sucks. When you say burning oil, do you mean there is evidence it's being burnt off in the cylinders, or do you mean you need to add oil and don't know where it's going? You (or a qualified mechanic) should definitely check for oil leaks in the engine bay and under the car, as there may be a thousand reasons (e.g. production error, loose clamps, etc). The B58 is generally a zero oil-consumption engine, but there are several cases of high oil consumption without external oil leaks. One possibility is that the breaking in of the engine (i.e. the first 1200miles from new) was either too soft or too aggressive and the piston rings did not bed in properly. Based on what I'm seeing on the forums it does seem that G20 M340i owners experienced this more than any other, I would say the B58B30O1 with 382hp is therefore most affected by the issue. It is strange that it affects the B58B30O1 more than the B58B30M0 and B58B30M1, as the engine block internals are identical to B58B30M1 (pistons, connecting rods, etc) and some lightly modified B58B30M0 are pushing alot more power than stock B58B30O1 (so it can't be due to limits of B58) . It might be that some oil is being lost internally or externally of the turbo, as this is a unique turbocharger to the B58B30O1 (different turbo to both the B58B30M0 and B58B30M1). There are several places in the B58 where the coolant and oil passages are near to each other (e.g. oil-coolant heat exchanger, etc), so when engine is cool check coolant expansion tank to see if it is contaminated with oil or increasing in quantity without explanation (i.e. oil entering the coolant). These are just some thoughts. BMW claims the oil consumption limit is something like 1 litre per 1000 miles, so if your engine exceeds this it needs immediate mechanical checkup (still under warranty). If the oil consumption limit is not exceeded as far as you can tell, then you have less to worry about but I would still ask the dealer to check it under warranty, there is a BMW procedure to check and verify the rate of oil consumption, and there will be a fault isolation procedure to follow in case of abnormalities. Hope this helps.
I heard s58 already has problems, is that true?
I'm not sure to be honest. However as a relatively new product, there will be issues in the beginning to be sure, as this is a natural occurrence with new products. Reliability is always relatively lower at the beginning and at the end of life for any product. The first owners with early production engines will encounter issues that later production engines will have corrected. This is the way the world works unfortunately: while alot of testing takes place before entry into service, once in service alot of in-service experience finds issues that testing never identified, or did not understand well enough with limited number of test cars/engines. Be sure that 2 years from now, the S58 will be more reliable than today.
I thought B58 was single turbo VS s58 which was twin turboed
Yes, that is correct. The B58 has a single turbo (twin scroll) and the S58 has two turbos (each single scroll).
S58 sounds heavy and complicated
Generally more modern technology tends to be heavier and more complicated, but remember that manufacturers are trying to reach the right balance between performance, reliability and efficiency, whilst meeting stricter and stricter regulations (regulations aimed at improving safety and reducing environmental impact). So the S58 is a technological marvel in my opinion.
It's going to leak oil like the Exxon Valdez.
Hehehe, all engines eventually leak oil as the seals degrade or the clearances increase with wear.
Not the same engines.
🤣
worst video ever on engines, I feel like a sucker sitting through it
Thanks for the feedback. Can't please everyone. :)
All you did was read off of the S58 technical training manual. Lol
So? Some people would rather have somebody explain it to them like a visual PowerPoint. Have you ever been in school and attended a class where the teacher throws a book at you and expects you to get it?
@@paradeinberlin he didn’t explain anything. He just read from the manual.
@@RB-xv4si I mean, the video is a little more than that, don't you think? :)
agree, this guy is a buffoon.
These engines are impressive, but so over-complicated. Honda can make engines that are better, more reliable, and def. over-built. An SI engine at 200hp has forged crank, rods, and pistons (maybe). The stock SI engine, the 1.5L T, can easily handle 300hp +, and the Type R engine can easily handle 500hp without a rebuild. And Honda is more reliable and doesn't leak oil on purpose from the factory.
S58 the new b58
Great video!
