The ULTIMATE German V8 Engine Tier List

[@alexb00007]

M113k deserves a mention and should be in S-tier

[@richardvank]

The M113k is good for the A-tier, but M155 should be 100% in the S-tier

[@livinglegend8953]

M113 > Anything we not even talking ab the great potential this platform is becoming these days

[@ctykckcktyvc7558]

had to be de rated from factory in the sl55 as the standard 1000nm of torque ate gearboxes too quickly, such a good low reviving engine

[@can_opener755]

@@ctykckcktyvc7558 funny story, my father had a '01 CLK55 with a standard M113 5.4L. He decided to tune it to a similar spec to the CLK DTM and converted it to a M113K. Suffice to say, the transmission didn't enjoy that, and while it still lasted 25,000ish miles under the insane load, the torque converter eventually failed, and it needed a transmission to move...yeahhh the M113 platform is incredible, but the rest of the powertrains of that era weren't capable of handling that type of power through it for long

[@newb529]

On my 2nd 113k

[@hugoduff2008]

I’m a bmw guy but the m156 in c tier is crazy. That’s a legendary engine and should be in a tier or at least a tier

[@kbcarroll]

I'd accept putting it in C tier due to reliability problems. But referring to it as "respectable power for its time" when it was the most powerful naturally aspirated V8 ever built "for its time" is an odd miss. And then the M159 is the same motor with all the problems fixed only makes A tier?? M113 and M159 are S tier. In 2003 MB made several of the world's fastest cars in multiple segments and you can find those cars still smoking Mustangs 20 years and 200k miles later. That's S+ tier.

[@babypluto3746]

@hugodugf9321 basically everything BMW has ever done is C tier when compared to Japanese vehicles so chill out homie

[@lukeisrazor9321]

​@babypluto3746 in no way is that true unless you're talking about reliability, if you’re buying a car for that reason then you don't actually like cars/engines

[@KirillSapelkin.]

The M156 is a legendary engine, surprised you’ve rated it so low especially in comparison alto the rod bearing throwers on the M3 & M5. M156 was AMG’s first love child post merger I’ve experienced most of the engines in your video and maintenance wise the M156 just requires frequent attention to oil and serviceable items such as injectors and seals.

[@taliyy_]

As a bmw guy m156 was my first love and i agree

[@waisoserious3017]

That's crazy that th S65 is S tier but M156 is C. More power, more reliability, more widely adopted.

[@Itsamugsgam3]

Im not gonna lie there was some Beamer bias here if my m273 gets hit that hard the e92 m3 engine has no right to be in s tier lol

[@pajamallama2364]

M156 in c-tier is a crime. Otherwise great vid as usual!

[@running2redline]

That’s completely fair, glad you enjoyed!

[@DanielSadjadian]

The M156 is such glorious sounding V8, love that engine.

[@RealDougFields]

M113/M113K is a Top Tier engine. The performance they have while still going 250,000+ miles makes them pretty unique. None of the more modern Mercedes engines you listed have a better combination of power/longevity.

[@DT-7727]

The later versions of the m156 on the w212 and w204 are close but the m113/m113k can't be matched in reliabilty wise

[@StupidFastTruck]

Great video as usual. I have a BMW 550 with the N63 I've owned for nearly 10 years with almost 100K miles on it. While I agree the engine can be problematic my own personal experience with the engine has been fine. It was one of the first applications of a HOT V where the turbos are mounted in the V which attributed to many of the issues. If properly maintained it can be reliable and has very decent power.

[@running2redline]

Thank you, that’s great to hear and proves that reputation isn’t everything.

[@brokeq50boi80]

⁠@@running2redlinewell also the main thing with the n63 is also that BMW will give there engines technical updates. Which will usually just take the original engine and just fix the reliability problems most of the time. So there’s technically a n63 and a n63tu which has some of the issues addressed. It’s weird that the s63 didn’t inherit most of the reliability problems and then they did the s63tu which fixed most of the reliability problems that it inherited from the n63 lol. Weird that taking an engine and having the m division do their thing to make it a m engine fixed most of the reliability problems.

[@running2redline]

I didn’t realize that was a thing but that’s super fascinating. It does make you think if some of the issues come from trying to cut costs when the M division has a bigger budget. Thanks for the info!

[@brokeq50boi80]

@@running2redline no problem man. Just figured I’d put that out there. I only found out because I was doing some research on the s63s because I wanted a 2015 BMW m5. Then I fell down the rabbit hole and learned about their engine codes and stuff. So whenever you see the engine code and then see tu after that’s the technical update which fixes some or most of the known issues with the previous one.

[@brokeq50boi80]

@@running2redline also it might be because the m division has a higher budget but, I think with the n63 it was mostly a case of it was the first time they did a hot v engine.

[@IacobucciB]

The 06-early 08 M273s were the engines affected by idler gear failure. I did my research before buyingy S, so I went with a 2009. It’s an excellent engine. Quiet, silky smooth, and gobs of torque to propel the big chassis around. Mine’s at 163k miles and doesn’t leak, burn oil, or make any abnormal noise. The only maintenance it has received are the rear PCV cover, thermostat, and oil cooler gasket, as that did eventually start leaking. Shame that they’re more known by their early production faults, as I’d put the later models right up with the M113.

[@Itsamugsgam3]

I actually have an 08 myself and have only really run into standard maintence(thermostat etc…) at 146k. The biggest issue to my understanding is the timing chain guides tho I believe the problem was fixed with 09 but it’s a one and done 1.5-2.5k job at a reputable shop. Least I’m not throwing rod bearings lol.

[@SensorJunior]

I have a later one, 2010. 220k km on it. Runs smooth and has a really fun power output. Really fun to drive (e550 coupe) No problems, at all

[@dedratrs]

I have a 2021 C63S with the M177 and it rocks. No engine issues so far with almost 17k miles, and I rip it pretty much every time I get the opportunity. Power delivery is consistent up the gears and it never feels like it's being pushed too hard. I think it could easily handle 700hp, but I don't want to void my warranty two years in.

[@martinmauleon2025]

You should include the technical update versions of some of these engines. The N63TU3 in newer -50i models and Range Rovers is a vast improvement over the earlier iterations.

[@running2redline]

Had I known that’s what they did I totally would have. It’s neat that BMW lets an engine run a little than fixes its issues.

[@stefanomarcellino6701]

I was wondering this also. I love the newer N63 in the m850i

[@aix4319]

Quite so, if the improvements is significant, shouldn’t him put this engine into different section?

[@mattcrad8605]

As an American that drives a C63 I was stunned the M156 didn't get more love.

[@user-Terracer]

ditto - I have over a hundred K on my latest and have had no issues!

[@saadgharbaoui4495]

2011 and newer M156 is a perfect engine, it did have it’s things between 07-11. Also the M113K is by far the most reliable V8 in this list.

[@stormdancer1910]

The N63 got a "Technische Überarbeitung" in 2013, solving most of the issues it had from the beginning. So i would put the "normal" N63 in D tier, but the N63TÜ in the B or A tier

[@running2redline]

I learned about the technical updates from these comments and looked into them. They really do make a large difference and it’s a wise way to maintain quality

[@questionyourself718]

Thank you for the making this video! Currently an owner of a 84 928 with a 4.5L 16 Valve gen 1 V8. At the time this engine had come out it was a beast. Still one of my favorite v8’s to drive and hear doing over 60+ mph.

[@running2redline]

I’m sure that car is a head turner, Porsche really doesn’t miss!

[@BashingBrainez]

To note, the bmw n63 has gone through many updates. The n63tu solves the injector issue as it removed the pzeo injectors also found in the n54 i6 engine and used the injectors from the newer n55. There are also n63 tu1 tu2 and tu3 now. This also applies to the s63.

[@yuriyzaharchyshyn4377]

S63 is literally upgraded N63. How can it make such a leap from D to S tier?

[@brokeq50boi80]

Because the m division doing their thing with the s63 fixed some of the reliability problems it inherited from the n63. Then the s63tu, the technical update fixed even more of those issues.

[@running2redline]

Nailed it here ^ that’s my same reasoning. Thanks for watching.

[@darylmorse]

There were updates to the N63 as well. They were much more reliable than the early version.

[@sethsteener]

The M113 is arguably the most reliable V8 of all time, alongside the 1UZ… should belong in S-tier.

The M60, M62 and S62 are also indestructible and yet he ranks the S65 above them all which has serious flaws namely the rod barings and throttle actuators. This guy is just fucking stupid the M113k is one of the most well-known and respected German V8's the fact that it isn't on this lists is reason enough to disregard the list as a whole. He also put the M156 in C tier an engine which is held higher regard than the M113k and most of the other engine on this list.

[@markomaric903]

​@@stroock6394 i would buy 2005 E55, but I think those are to old cars now, and who knows who drove it, and had it maintained well or not. On the other side if you have to rebuild all engine, i think it would cost a fortune

[@gonado]

As far as I know the S65 have also bearings problems. I would switch places with the S62

[@cheberlo]

Bearing problem is consequence of poor maintenance and bad oil, nothing more, I've owned s65 m3 e92 for 4 years, not a single issue, my dad was bmw engine assembler in Germany back in the days, he owned s62 (m5 e39), and to this days he refers to that engine as one of the most reliable cars that he ever owned. I said all that just to let you know that most of the problems in bmw's engines is consequences of poor maintenance. Edit: not only bmw engines, most of the German "unreliable" engines aren't unreliable if you maintain them properly, maintenance is expensive, but still, its a performance engine and they need proper maintenance, maybe there are unreliable engines that doesn't depend on how you maintain them, but i didn't have any experience with em yet.

[@semird615]

The 4.2 FSI not being in S tier is a total crime. The BMW M3 V8 of the same era wasn’t better in any way and yet it’s S tier.

[@running2redline]

That’s definitely fair and valid, thanks for watching

[@koopergauthier6694]

Something I’ve always found myself doing, is going straight to Google to search these cars simply to see what they look like.

Thank you for breaking down such large group of engines into a clear classification. You did an amazing job. One small comment for the improvement is that you haven’t mentioned the money aspect. Generally, how much does it cost to maintain and keep these german beast in shape? Monthly or yearly. Theay are all different in terms of this either. I know prices for parts and labor may differ, but you could have provided general numbers. But I think this would make your guide ultimate for V8s.

Isn't that the engine that had so much carbon buildup when not often driven hard that it started running badly? I remember several german tuning and mechanic reports/articles/forum treads where that was a huge issue. Intakes had to be cleaned either checmically or mechanically for a lot of money, just like their 10cylinder in the RS6 they once had.

[@connor3288]

@@nirfz Direct injection only gas engines is so stupid, and engineers who built them/management who signed off on them are idiots. Toyota does it right by having both port and direct injectors, I believe ford also does that but only on some engines such as 3.5 turbo, maybe 2.7 turbo as well.

[@nirfz]

@@connor3288 I have heard that it was especially bad with that V8 engine the R8 ahd RS4 had. I have seen Mercedes going a different way in a Diesel engine they got from Renault: the "recylced" air that gets back to the intake to reduce emissions on cold engines in that specific case is taken *after* the particulate filter. Sure the filter might be earlier to replace in the long run, but the intake side stays clean.

[@danstarc]

You missed the Audi chain-driven 4.2 40v (non-FSI), which is totally different from the belt-driven versions. Also, the EA824 and EA825 are both 4.0T V8's but they are completely different engines.

Audi Engine EA825 shown here is in fact an EA824. SQ7 and SQ8 were never equipped with the EA824, both at this time were Diesels. The EA825 came first time in 2020 in the SQ models. Also Lambo used 825 but EA824 was built often altough they differ also massively between s and RS models (Crank- and Camshaft, different Turbos, different cooles and Audi has used different gearboxes).

Great tier list! My dad owned a 2008 X5 4.8i(N62). The sound of the engine will always brings me back to my childhood. Unfortunately my dad had to get rid of the car for the same reasons that the N62 is on the D tier. It started when we noticed issues with the head gaskets. Then the engine began to eat oil like no tomorrow. It started to leak coolant in its last three months and then it leaked oil. We often kept a drip pan under the car because of how bad it was. My dad kept putting in work to fill up the oil and coolant. The gas mileage was also pretty bad. We often got 12 Miles per gallon. The only reason why he got the car with a V-8 at the time was because he felt that the inline 6 option was seriously under powered. Eventually he let the car go and now owns a 2023 X5 40i (B58).

@@running2redline I've been thinking about the m113/m113k with the 5-speed, on the topic of reliability. re: the other options, I've also heard that most of their (MB's, especially AMGs) engines should be okay if serviced and maintained. Perhaps MB gets on to the issues quickly, and same with the recalls. Owners of these cars would be quick to address the issues and the 'one engine, one man' production process must make them as good as possible within the constraints of overall design and material choice.

I agree there that with most of them you will be completely fine, Mercedes has been at it longer than almost anyone, and always puts out quality. It does seem that most German engines do much better when maintained properly.

​@@running2redline In your opinion, do you think the S7 and RS7 would be more reliable than the [C219] CLS500 (5.0) and CLS55 AMG? Basically, the Audi's are a generation newer and have the 4.0 listed in the S tier, whereas the MBs have the M113/K listed in the A tier. I could go either way.

M62 had entirety different metallurgy then m60. M60 had nikasil coated cylinders that US fuel dissolved. M62 had acid etched alusil walls. Basically aluminum and silica made up the block, a microscopic layer of the aluminum was removed on the bores effectively making silica the wear surface of the bore. However the timing chain guide is real, had to replace mine at 200k miles. I think that's a fair interval, but some people have it happen much sooner. Thing leaks bad too, even after most gaskets replaced there will also be some stupid o-ring that leaks. After putting 120k miles on mine (230k total), hpde days, and autocross. I'd still rate it at B teir, enough power, reliable enough, but nothing special. However it sounds beautiful.

2004-2006 audi a8 had a 4.2 40v with a timing belt and is one of the most reliable engines i’ve ever owned

[@Swiss4.2]

Those were the last truly reliable Audi v8 engines. All the newer stuff with the FSI injection have problems with carbon buildup, injector failures, bore scoring and lets not forget the infamous 4.2 FSI timing chain disaster. Those belt driven 40 valve engines are bulletproof and can easily do over 300k miles if you maintain them right. Theres a Canadian guy on youtube called Veikra who has one at 550k kms or 340k miles, I even saw someone on a forum post about how his A8 reached 800k kms or roughly half a million miles on the original engine.

[@kilian20v]

Great video as always 🫶🏼 But here I am, demanding a five cylinder video again🗣️‼️ (give the fiat 5 cylinder a good ranking)

[@technicalnonsense]

To anyone out there who owns a BMW with the N63 TU engine whether it's the TU, TU2 or TU3 it is extremely critical to not follow the BMW suggested oil change interval of 10,000 miles. Change the oil every 5 to 6,000 mi. My TU3 is currently at 40,000 miles and I religiously change the oil every 6 months or 5,000 mi, I have never experienced any oil consumption with this particular engine

[@running2redline]

Interesting, 10000 does seem like a long time. Thanks for the info

[@RicardoMartinez-kr5qk]

hey can you do a best 8 valve 4 cylinder video

[@running2redline]

Not currently, but I’ve started with high cylinder engines and have been working my way down. It will definitely happen though!

[@jamescarl6187]

The N62 is actually a very good engine and if taken care of can last a very long time. The issue was bmw used bad seals which made the engine prone to leaking but if addressed and the problems fixed/ the engine rebuilt it is a very very good engine much better then the M62 and N63

[@chesapeakemotorwerks]

I agree with this. While the N62 has some expensive problems, they are generally more reliable than the M62TU and once addressed it's actually a great engine that produces significantly more power. The only glaring issue these days is really the valve stem seals which can be expensive to fix, but other issues now have aftermarket solutions that help reduce repair bills. For a daily, I'd take it over any of the hot-v successors. Overall, I'd probably rank them as S62 > M60 > N62(TU) > M62 > S63TU > M62TU > S65 > S63 > N63.

[@running2redline]

I like that idea a lot!

[@nelietis96]

Great video for comparing german V8, but It feels like the details and research for the video was compromised towards the Audi and Porsche as because you skipped tiering Audi engines by the engine code, you missed that all the engines up to C5 D2 and couple of D3 Audi were timing belt driven(except allroad), skipped the BBK 40v timing chain engine all together, and overall the many diferences between those engines and their strenghts and weaknesses that you had in BMW and Mercedes categories. Keep with the interesting content and carry on.

[@running2redline]

Thanks, I’m glad you enjoyed. You’re completely right, it’s not because I got lazy with it, more so there was way less documentation online for the nomenclature. I dug as much as I could but information was hard to come by. Hopefully most of what I did find was accurate.

[@byronjones4635]

Definitely some bias favorable to BMW in this video. You called out the M156 for its issues and put it in C tier but didn’t call out the BMW S65 and 62 motors for their rod bearing issues.

[@maxgr7723]

S62 isnt so bad regarding rod bearings. They just got the wrong oil for the daily use(should have been a 5w40 or 5w50)...they timinguide is more of a problem in my eyes

[@running2redline]

Must have been a coincidence, but I do agree with that assessment. For what it’s worth I’m actually a big Chevy guy, thanks for watching!

[@Fastboi69420]

Pls German 4cyl when, I wanna see what you find out about and think of the ea888

[@Itsamugsgam3]

I feel like a few reliability problems were ignored on beamers while Mercs got hit way harder for it I’d rather deal with timing chain guides over rodbearings and Vanos. The m156 is an s tier motor if judged by the same standard.

[@oitaeduard]

M156 S tier for shure

[@kainariylius392]

You left out a very important 8cyl from Vw..... the W8, predecessor to the w12 and w16 in Bently and Bugatti.

[@patriklenck1735]

The 4.2 fsi, has a massive issue with Carbon buildup due to the Internal AGR wich opens the Intake valve earlier in the Exhaust stroke in mid to Low rpm Situations. Otherwise a great engine

[@Fitzy215]

The m119 was in the sl class up until 98 I believe. I have a 97 and it has that engine

[@a_sher2805]

Was hoping you’d talk about N63TU 1 and on lol

[@Latoria]

Even though it's not a V8 I would've loved to see a honorable mention of of the W8 found in the Passat and some of the Bentleys. Crazy unreliable engine with pretty low power output for what it is, but amazing sound and incredibly unique design and use in a normal family sedan. Amazing video though!

[@running2redline]

I’m glad you enjoyed, I’ll likely make a video for all W engines, a lot of W12 and W16s with it. Thanks for watching!

[@MARCO-rq2ph]

the 4.2 litres audi in the s5 is completly different from that one in the rs4 / rs5,just same displaicment

[@Ethan007Hacks]

VW/Audi tech here. The early audi 4.0T seen in C7 S6/7 RS7, D4 A8 Are JUNK! Rampant turbo failures leaking to engine failure. They do make crazy power and don’t have many other issues though

[@MaxthonFan]

I wouldn‘t group the Audi 3.6 and 3.7 together as they are not related to each other. The 3.6 was developed from the Golf GTI inline 4 soley for the Audi V8 and has a bore of 81 mm. The 3.7 is a destroked 4.2 with an 84.5 mm bore.

[@MigotRen]

Cant wait for an Inline 5 tier list *-*

[@running2redline]

Good news is that 5 cylinders are up next!

[@MigotRen]

@@running2redline Looking foreard to it. I will never get over the sound these make. grandpa had an ur-quattro. Sadly i never got to see that thing as he sold it years ago. Friend has an audi 200. Even with just 136hp that 2.1 5E sound with a remus exhaust it sounds amazing. I myself have been an rs3 owner for a year now. 2016 with the ea855 (not the evo). Still, Technically very impressive engine - aside from some powerrobbing carbon build typical for the pre evo era as they just have direct injection. Thicker oil and a catch can can help. But overall very solid. Amazing responsiveness for a high power turbo engine. Vvt all arround and avs on the exhaust valves. Water cooled turbo with an additional trailing pump to avoid coking. As for reliability Properly warm it up before giving it the beans, keep up the oil changes every 10k km, preferably not the 0w30 longlife stuff and they just keep going. Even with a 420hp stage 1 at 125.000km now, no signs of problems. Ive heard of cases of timing chain elongations, but so far no signs of that either and the camshaft sensors usually catch that before it breaks. Power Potential, especially with the evos is crazy as you can just mount bigger port injectors on those. I mean iroz gets these to over 1400hp with so much boost one of their intske manifolds exploded. Engine was fine lol No wonder you pay 10k+ on an s3/golf r. Basically the same car but that extra money all goes into that overuild drivetrain. How much 1 cylinder can change the character and that dq500 gearybox can handle 1000Nm with a clutch upgrade (800 stock) which is leagues ahead of all the other vw DSGs

[@running2redline]

RS3 is one of my favorite street cars, that's absolutely awesome! Interesting how much abuse they can handle.@@MigotRen

[@MigotRen]

@@running2redline If you want some reading material, there is this quite elaborate self study on the 855 EVO by audi static.nhtsa.gov/odi/tsbs/2017/MC-10127901-9999.pdf i havent found such a thing for the pre evos. But this little article should give a nice overview. (czgb, last iron block variant) australiancar.reviews/Audi-RS3_CZGB_Engine.php

[@Le_Dislike_Button]

S65(based on s85) and S63(based on N63) should be tied with M156 and M157, all are impressive high performance engines plagued with reliability issues. M273 from 2008+ is decent, I'd put it in the tier same as the M60, another otherwise fine engine with reliability problems in its first few years of production. In fact it's probably more reliable than the M278, which I hear many horror stories about, particularly about problems with bore scoring. M113 and all of its derivatives belong in the S tier. these engines can produce M car levels of performance and retain bulletproof reliability. it's the closest thing to a German LS if there ever was one, and easily one of the best engines Mercedes has ever made.

[@BobBenz55]

M113K … my favourite engine 👌

[@maxgr7723]

Personally id not rate pure oem output or aftermarket turningcapability into account for ranking. In my eyes id rate from all of those bmw engines following into s tier: m60(as bulletproof as the m113, super loved in e3x communities, some alpina 4.6s were dynoed around 400hp), s62(the best out of the m62 generation with doublevanos improvement!), s63, m113, m155(where you've got the carbon built-up information from?), m156(apart from the valvetrain no real issues)...A: M62,M119(more of a counterpart to the m62 in many aspects), m117(would be s tier if taking amg 4v option),m116 and n62(because if well maintained and with a lowtemp thermostat improved/precared is one of the best modern v8s), S68,S65(has to many flaws and broke up to much with its ancestors)...everything else b c d

[@W-Mode]

As m60 dude With the hybrid build m60 is the goat for 90s German v8

[@siegfriedbarfuss9379]

Why is the M119 higher ranked then the M113? The M113 has more torque, better power consumption, less moving parts, less parts and scales amazingly well consider M113K etc.

[@running2redline]

That’s certainly a valid point

[@gradyfuller1619]

Looking forward to the 4 cylinders

[@Shockload]

I would understand if you put the M113 in A tier, but M113K ?? that is easy S tier, did you forget about the iconic CLK DTM ? that alone gives it an S tier and it's still reliable af

[@maurimh690]

Nobody has forced Porsche to do anything at VAG, since the Porsche family is the majority shareholder within the Volkswagen Auto Group. Furthermore, Volkswagen has not built any V8 engine, only Audi, since Audi's developments are not always shared with VW but vice versa, that is, VW must share its developments with Audi, Porsche, SEAT, Skoda, etc. All of these are guidelines coming from Porsche SE (the company, not the brand as such), which also does not share its developments with Audi or VW.
