Mercedes-AMG Engine Tier List

In this video, I go over Mercedes-AMG engines over the years and rank them on a tier list. I rank all of the engines that I have covered in previous videos such as the m113k, m156, m157, and m177 just to name a few.

Note: at 8:13 - Since making this video the M159 is no longer the most powerful N/A V8 since it was surpassed by the 2023 Corvette Z06.

[@greydog1104]

It's still the most powerful with a cross plane crank.

[@butcheredalive]

The fact that it kept that record for almost a decade still makes it S tier imo

I’d say A tier is fair and the reason why is because the SLR variant… it’s just that little bit better.

[@pfoxhound]

You forgot about m113k model for e, SL class, the one that has double oil plug and rubber o ring in oil system. That rubber becomes stone and later - engine becomes unreliable. Too much work to get to this 1 dollar o ring. If I interesting - look for m113k o ring videos.

[@stfu7308]

m156 is probably amgs most iconic engines but unfortunately it has many issues such as the headbolts, which were revised. But the oiling issues, valve buckets and camshaft wear were one of the reasons I wouldn't say that it's reliable at all.

[@patricksmith1550]

He did the same with corvette engines, seemed to gloss over serious issues like how he glossed over the M156 headbolts. That is not a minor issue with that engine. Sure it was solved after 2012, but there are 5 years of the engine with a serious flaw.

Way off on the M157 placement. That engine was good enough to replace ALL M156 cars (except C63, they didn't want to outsell the E-class like they did with the NA w212 E63) however this motor is the flagship V8 that came with the best transmission AMG made, 4matic, eco start/stop, got below gas guzzler tax, and tune only puts out the same power as the 65 V12s tuned. It's an incredible motor and probably the best performance bargain as many M157 cars are still very close in performance to AMGs current M177 powered lineup. All in all I think it deserves S tier consideration.

Don‘t agree with your compartion M156 and M157. M156 has a lot issures more than the M157. M157 has the most potential of increase of power and torque. And chain problems already fixed up from 2013. And it is the last engine with high engine volume of 5,4 liter. Don‘t forget it was the first engine with biturbo, 4matic which was built in mercedes cars. And compare to M156 it was a complete different engine construction with high fuel efficency.

[@kennethderamus5277]

Great video, I would definitely swap the m156 with the m157 on the chart. Performance the m156 was in marginal step down from the m113k, reliability the m156 was one of the most unreliable Angie motors. And not just little things, catastrophic failures with head bolts among the other things you're familiar with. The m157 has been a proven platform for a long time, much better on gas. Yes, we are familiar with Taos 's video, but bent rods is a rare issue only with truly maxed-out engines.

[@H.S.H.M.]

Agreed with literally every single placement, except for the M157 should still be in A. Yes it was not as "special" as the previous M156 & M113k but the tuning potential with a simple ECU tune at the time was crazy. You would need a Weistec supercharger on a M156 to make the same power as a M157 with nothing but a ECU tune. Modded stage 2 M177s today are still just putting down the same power as a tuned M157. It has its own issues yes, but is still more reliable than the M156. Its the last "deep rumbling" V8's AMG produced before the 4.0 M177-M178. Ethanol tunes finally came out for the M157 last year & along with a TCU tune, people have been running 10's in the 1/4 mile, trapping over 130mph+ in stock block, stock turbo M157's...its quite a feat

[@stephanvelines7006]

The M133 and M177 / M178 are technically related. They use the same bore, stroke and cylinder distance, cylinder lining, head design and so on. The M177 / M178 is essentially the V8 version of this engine generation. Per liter the M133 (95.25HP/L) is more impressive than the V8 and gives a hint of the M177s potential even with emission relevant accessories (keeping in mind increased thermal losses and thermal stress on engines with more cylinders). Unfortunately with how things are going we will not see a V8 version of the M139 (105.25HP/L) anytime soon, as internal combustion engine development is coming to a hold at Mercedes AMG.

[@e46m54nissansr20937]

I'm just going to say this hater comment really quick but i respect the M133 for sure, but POPS AND BANGS doesn't mean an engine sounds amazing even for a 4 cylinder. Its an amazing engine in itself though for its output and design. People rather talk about Japanese 4 cylinder turbos and the GTi/Golf R but the fact is Mercedes AMG can build a more potent and characterful 4 cylinder turbo than any of its rivals

[@SPOOKZ305]

Yeah not being bias but m133 does deserve a C, it had the most output per cylinder at the time, & it certainly does have a unique engine crack when you shift.

Great video!, I agree with most of his opinions on these motors with the exception of putting the M156 in the same tier with 4 other motors that are practically bulletproof and and share massively impressive attributes. I give serious kudos to AMG for what they accomplished going fully independent and incorporating racing technology in the creation of the M156; not to mention that it sounds AMAZING more so than the other motors in that tier. However, with cooling, headbolt, and cam adjuster issues, causing, in some cases, catastrophic failures, I don't feel that it deserves A tier status. B tier appears to be more like its rightful place. Just my 2 cents✌🏽

[@Jitzie]

The M133 is a turbocharged inline-four engine produced by Mercedes-Benz. Since its debut in 2013, it has been awarded International Engine of the Year three times in the "Best New Engine" and "1.8-litre to 2-litre" categories. D Tier... ok, I had a 2017 A45 for 5 years and that had a crazy good sounding exhaust, it was much louder than the previous iteration.

I think the reliability issues of M156 are overstated, yes they can be costly but they are known. Catastrophic failures are rare, even the head bolts issue, and plenty of cars are pushing 200k miles without any head work. I respect the M113k, but I don’t think the reliability and ability to mod is what makes an AMG engine special. The same can be said for a lot of Japanese and American engines. The M156 is the pinnacle of what it means to be an AMG engine: superb German engineering and a sublime sound.

C tier seems more approriate.

[@jdavidblais]

complètement d'accord !!!

[@pranavvaidya3590]

Yes, I agree. The use of a 4-cylinder by AMG was looked down upon, but people forget that the CLA is a very small car and is on the lower end of the Mercedes lineup. Even with the 4 banger in there, it's a tight fit inside the engine bay, so it would be impossible to fit an 8 or even 6-cylinder in there. Putting that engine in a 63 AMG isn't acceptable, but in a 45, it's perfect. As for power, sub 400hp from a factory turbo 4-cylinder is pretty good. It also sounds better than most other 4 cylinders.

[@robertlambert5299]

M113k of course.

[@GamingJamesGames]

In my opinion, the M156 and M159 are the best and I think will remain to be the best N/A engines in the world. It's sad that new N/A cars are just getting rarer and rarer thanks to emission regulations. With that, there aren't that many good solutions to keep an engine's original displacement. Manufactures either A. Put even bigger OPFs, B. Twin Turbo or C. Kill it completely. It's disappointing to hear that the next C63 AMG won't even have a V8.

[@biaritzsiroko6117]

Glad you understand this well! we want sound, volume and power! otherwise we can just buy a Toyota. I hope AMG wakes up and keeps making the brutal V8's and V12's !

[@stephanvelines7006]

The M133 (2.0 I4 T) and the M177 (4.0 V8 TT) are actually close relatives from a technical standpoint. As the per liter output of the 4 cylinder M133 is higher you can estimate what potential the V8 version has, even with emissions accessories (keeping in mind increased thermal losses in larger engines). The next possible step for AMG would be to make a replacement for the M177 / M178 based on the new M139 2.0 I4 T engine. But sadly as internal combustion engine development is coming to a halt in Germany we might never see such replacement. Instead the M139 - possibly the large scale last internal combustion engine of AMG - will creep upwards through the Mercedes lineup (new C63 hybrid).

When you think of AMG the m156 comes to mind. It is arguably the best sounding muscle engine of the modern times. I also think the m276 is under rated, it is generally seen as better sounding and more exciting than the equivalent Audi V6 and BMW B56 even though the B56 gets all the attention. Finally I'd say the m155 in the SLR while a good engine is extremely expensive to maintain and doesn't have a high redline as many would hope in a racing inspired engine.

[@mrmerc7931]

M279 is worth mentioning in my opinion. Revised version of the awesome M275. I’d put both M275 & M279 in S tier bc it’s been in production for 21 years and still going in the Maybach, awesome sound, pretty reliable, big power, used in the Pagani Zonda…

[@doggSMK]

M104 needs to be atleast B tier. People a making over 1000hp with it. On stock internals it's good for up to 400hp. The M119 very underrated solid A tier, The Kangaroos Team made 717hp and 771nm on stock internals with twin turbo setup. PS: Like many said M113K is S tier, with some tuning (stock internals) it gets 750-800hp so quite well built. I wish AMG did OM606 turbo as their diesel option. It makes crazy hp (over 600hp) only with a big turbo and more fuel. That's the diesel 2JZ lol

[@Horologyfred]

I have 09 sl63 m156, the 04 sl55 m113k, my wife’s car, we swap. If I need to go on the highway it’s the 55, if I. Want to drive for fun and visceral experience, it’s the sl63 m156, the tranny makes the sl63 stand out. At the gas station, 3 of 10 ask questions with the sl55, 6 out of 10 ask about the sl63. The 63 sounds like nothing else. If you had both, you would probably feel the same, I won’t sell either. Both cars are equal in speed, and the mechanical issues of the m156, are just on the Internet, I have never had any problems with either cars motors. I had the sl600, it was fast but didn’t feel like an AMG, the 63 m156, is the last motor of its kind, the rpms go from 2k to 7k in a second. I have 94,000 miles on the m156, nothing broken except parts attached, motor never opened, but the motor snaps back when you downshift, it’s a gun going off, only the Z06 slowly passes me by, not the 911, expect Turbo. But the quality is so strong on the sL R230.

[@slsamg_5thscale]

I'm glad you put the M159 in the S-tier!

[@print-master]

My first MB was a C43 AMG estate with M113 100% reliability over the 12 years and 70,000 miles. Sounds great and v fast. Last Year I sold it and bought a C63s Estate with M177 which is another story...+200 more horses and monsterously quick

[@mak62183]

The stance of that black E55 is PERFECT 👍 😘

[@jugobetrugo7213]

the m113k is the most reliable (amg) engine ever made. it should be S tier

[@burnttoast5318]

M113K FTW

[@Czechbound]

This was really great. SUGGESTION : Putting a timeline on the x-axis would allow us to better understand the development over time.

[@Aris_Groumpos]

The M119 was also used in the sauber C9/C11 with twin turbos setup.

[@mohammadalfattal2902]

yeah and in CLK LM, M119 deserve S imo

[@suninrobrobinsun3039]

M157 maybe should be in A section💪🏾

OM612 maybe wasn't as AMG planned but, sure it's impressive. I wish I had a w203 T model with the 612

As far as diesels goes the om629 takes the cake. More torque than an Aventador back in 2006.

I didn't know that AMG made a diesel engine. The M119 engine is definitely my favorite because of the sound and the sheer reliability.

M276 sounds so good for a V6, I'd swap the m256 and M276

He was Crazy to put that excellent engine on the D list.

[@shariarkhosraviani2059]

Yeah, this guy is stupid. One of the most reliable Mercedes engines is the M276, he didn’t do any research on this engine.

[@lilchu7336]

This whole tier list favors V8’s ☹️ The M139 needs justice for being a closed deck engine the highest HP i4 engine. Tuning capabilities are mind blowing too

[@Mermasora]

Bro put M276 bulletproof engine below M256... Such a kindergarden level opinion...

[@BLACKRAINW11]

Thank you so much for this simple video 4 my favorite manufacturer's performance division 👍👍👍

[@Coldbrew365]

M133 is definitely an A tier. I’ve got it with factory optional AMG performance exhaust upgrade in ‘15 GLA45 and it sounds glorious. And it’s a solid engine.

[@16vr6]

M112K is the best-sounding V6 for any production car IMO.

[@ecomasterster]

awesome video, hope one day I can afford E55 with M113k.

[@joshuaghiroli2513]

I think the M139 should be B tier and M178 should be S tier, just for the simple fact it has a flat plane crank in the Black Series. The M113K could also be argued up a spot in my opinion.

[@ibeloly]

Will be great to see same engines ranked, with only criteria being reliability! Guess m275 will not be S tier... Thank you for your videos.

[@poisonouspython1410]

you'd be surprised. There's a 300k+ original mile m275 still on the road... don't ask me how I know ;) Fluid maintenance is key

[@thatmatty231guy]

I have an M275 with 180000km on it - its a very reliable car i just have an oil leak i need to fix on it now but otherwise its been fantastic.

[@poisonouspython1410]

@@thatmatty231guy It's barely broken in then haha. The one I'm speaking about literally has 550,000km and it runs like a top

[@thatmatty231guy]

@@poisonouspython1410 Wow 550k? Holy shit thats nuts haha. Yea mines brand new then lol. But yea they're truly fundamentally solid - and they're still pretty basic just a massive SOHC 3 valve V12 with a couple turbos bolted on.

[@poisonouspython1410]

@@thatmatty231guy Yes, you've got a long while left on the clock with your engine haha. I'm a car longevity snob with vehicles so both of mine have over 550,000km but you would never know it from the way they look or drive. And yes, the lack of variable valve timing is important, but most important to me when selecting an engine platform to hypermile is PORT INJECTION. I literally have original injectors in both my engines with over half a million km and the valves are clean as a whistle.

[@Jazzmaster71]

M256, you should do more research. this is the first mass produced engine with the built in 48V Alternator/generator. It has no auxiliary belts as well. I would say it is revolutionary in an ever so dull engine world.

[@alansoler2653]

Awesome video bro!!

[@jeffreytsao]

Speaking from M177 owner, M133 should be at least C Tier along with M139, if not higher (for both) due to V8 "favoritism", also I think M178 particularly the LS2 on AMG GT Black Series & Aston Martin Valhalla definitely deserves the S Tier, great list though, thank you for putting them together.

[@tigelee7818]

Love this video! I own 1996, S320 and 1992 S350 turbo diesel! They still perform miraculously well at 2021! Love to know more about them. I inherited them by accident!! 😊

[@aex.og_ace]

M297 7.3 V12 and M157 5.5 V8 💀🤤🗿

[@thatmatty231guy]

I've had all the A tier engines apart from the 178 - and my favourite would have to be the 113k and just behind it the 275. The 156 is lovely sounding but not as thrilling as the 113k's torque. I think the 157 is probably fair enough in B tier - its still a monster motor but its a lot more 'electrically limited' feeling - in saying that though, the 177 feels that way too! Even with ESP off my C63s used to feel still somewhat delinked from the accellerator pedal.

[@quinyboties]

It’s transmission torque limits and bov vales. I got an ecu tune, down pipes & tcu tunes plus bov vales from zac and carbon intake. The engine really comes alive! Throttle response so much better. I know what you’re saying by the m177 feeling electronically limited, that’s because it is. The ecu and tcu tune really fixes that feeling

[@erissitone]

Good job old man, very very interesting. Please, more videos!
