Mercedes AMG has cranked out a gem of an engine. The hand built M139 is a 2.0L turbocharged inline four-cylinder that makes 416 horsepower! That makes it the most powerful turbo four-cylinder engine currently in a production car! The M139 engine is used the Mercedes GLA45, CLA45, and A45 vehicles. 416 horsepower at 6,750 RPM and 369 lb-ft at 5,000 RPM. With a displacement of 1991 cc, the M139 makes over 208 horsepower per liter! It also has some of the highest peak combustion pressures of any engine.
How did Mercedes do it? Clever engineering. From the engine layout, to the roller-bearing twin-scroll turbos, to the block and forged internals, to the cylinder head, to the spray on cylinder liners, the engine is packed with brilliant engineering features. How does it all work? Check out the video for full details!

NEW VIDEO EVERY WEDNESDAY!
How did Mercedes make the most powerful 4 cylinder engine in the world? Simple. Boost. Boost. Boost, with a generous helping of yet more boost.
Maybe afterwards we can get some boost to celebrate
Ye the boost is important here, but they also had good decisions and ideas presented in this engine , like he said in the beginning in the video
its easy to boost but its hard to make a boosted engine and put a warranty on it
Everyone and everything uses forced induction now. I personally don't find it very exciting or interesting myself.
This thing needs a supercharger though, looks like you have to rev the crap out of it to hit peak torque and hp. My twin charged volvo s90 does it right, minus about 100hp. It can use the supercharger and turbo at the same time and I've seen it pushing 23psi.
Well I guess it only has to last until the warranty expires!
That would be a first for Mercedes.
That's been what i've been thinking about all these new preposterously-high output engines.
Don’t expect longevity for the vehicle with this engine. I predict the vehicle with this engine will lose 90% of its value in less than five years.
Which is better and why Twin Scroll turbo OR mazda 4-3-1 exhaust whit Ejector Effect ? Psl !help!
You mean Maserati?
Meanwhile, at VW, "how can we make a plastic engine block..."
VW: "We saved 180 pounds on the new Golf!"
Lmao
Haha you’re not wrong, I swear the 2.0t in my b6 Passat and vw cc are like 30% plastic on the top. A brittle broken nightmare.
Ve vill make make a plastic engine und.... more boost? (Um-tsss Um-tsss)x2
@@gepixelt7712 180 lbs is a lot. Must be more plastic! I guess it will fall apart 180 times faster then.

Yeah and 2 electric motors what u tryna say
@@alialsafaar6147 even without it's still 600hp. That's gotta count for something
Four minutes in and we get the answer, 30psi of boost.
Slap that turbo on almost any other 4banger, see what happens. That's the point. Edit: people need to open their ears to key words like IN PRODUCTION TODAY.
But just a couple minutes later, you get the answer of how it can withstand that pressure. 😆
Boost pressure doesn't always translate to more power.
Forged internals.
@@Trident_Euclid that is true.
Thanks Jason, for explaining some very complicated technology extremely well. The specific output of modern engines astounds me, having become interested in cars in my middle teens in the early 60s. At that time, American muscle was hitting about 1 hp/cu in on the hottest cars (about 61 hp/l.). The fastest European cars were getting close to 100hp/l, which was about what race cars got. I’m fascinated by this technology which makes more than 200 hp/l possible ON A PRODUCTION CAR! 😵
Pls help ! ! ! Which is better Twin Scroll turbo OR mazda 4-3-1 exhaust whit Ejector Effect
@freezeme360 Yeah, the 70s was a performance wasteland known for bringing us the 165hp Corvette. Early emissions equipment and super high gas prices didn't exactly make the case for the big block 60s American muscle. The thing that blows my mind is cars have gotten heavier, more complicated, more powerful, safer, and MORE RELIABLE. That's some pretty amazing progress.
It uses forced induction at over 30lbs of boost. Not really that special.
@freezeme360 He was talking about HP/L. 200hp/L isnt that special at over 30lbs of boost
at the end of the day it is all about making engines that can run and sustain the tremendous pressures forced induction can throw at it
Great improvements from Mercedes Benz and also by me, because I now understand your drawings and can follow the explanations through them, Jason. Thank You.
What is the most impressive technology for me, is the Nanoslide that "sticks" the oil to the cylinder walls that reduces the Friction BY 50%! and the TWAS which also compensates the Closed Deck Heads.
In my experience, I’ve found the heat saturation gains from mounting the turbocharger on the firewall-side of the bay can also aid in catalyst light-off and therefore reduce tailpipe emissions. I would not be surprised to hear this was also a consideration with the new EU 7 targets on the horizon.
What an incredible engine, it’s too bad that many owners won’t know anything about their amazing engine! They drive it because it’s an AMG and therefore has a lot of power.
I work for Mercedes, and we sell quite a few of the old gen 2.0 380 hp 4 pots. And most of the people who drive them do care, and do understand quite a bit about them... Trust me, you dont get a high power 4 cyl if you dont know about cars... Its going to cost a fortune to run if you dont treat it right. The type of people you are thinking of buy massive E and S classes with V8's ;) IE the E63s and the S63 and S65 Coupe
Captain_Coleslaw I’m really happy to hear that!
@@Captain_Coleslaw "i work for mercedes"...seems legit.
Its really not incredible its just a really heavily boosted 4-pot. Nothing new or innovative about it so far as I can see. Just makes a lot of power from few cc.Would MUCH rather have the character and vocal delights of the V8.

@@valentinuiliqnow6198 I guess at this point you should just look up the two technologies and read about it.
Yes, Jason is very knowledgeable but he doesn't have to own the junk his video's are about.
wysetech2000 I don’t think he’s turned many wrenches or painted many cars or any modification or rebuilt and blueprinted an engine or supercharger lolo
Not many people in the world share your talent. My engineering experience is limited to watching nerdy videos on CZcams. The way you compare things is always a relevant comparison, the way you explain things is always so easy to understand but still very detailed and technical. No fancy computer graphics but you don't need to, I can pause the video and analyse your whiteboard and it all just makes sense. Every piece of data you use is valid and if you have to estimate then you research the heck out of it to make sure your estimate can't be more than maybe 1% out. You carefully select the right words to use so there's never any confusion about what you're saying. Every video you make is like this. Really impressive. Thank You.
Mercedes : We have the most powerful 4 Cylinder
Honda Civic Drivers : But we have V-Tec
And if the name isn't enough, an additional plastic badge saying V-Tec will do the trick. As long as you don't actually have to compare them in a race, when screaming "V-tec!" on straights and corners won't help. ;)
Mercedes has ALWAYS been at the forefront of car technology. They have pioneered almost all major improvements on cars. They were one of the first cars to have fuel injection in the early 1950s.
Of course Mercedes is going to do it better, they are anal retentive Germans.
I love Mercedes, but theres something to be said for Honda engines reliability and being able to handle power. I have seen many tuners be able to get 450hp out of their 90s K motors and the new type r civic can produce over 350hp with a simple engine tune and while it may not be as much as the Mercedes, its nothing to sneeze at.
Shabuti R18 Audi is better
@@thenotoriousjoey9956 yes the audi is better but the type r is $15000 less and much more reliable 😂

It's a money pit brand new, people who buy these have the money to "waste" except you can't say waste exactly because they're paying for the luxury, not the reliability
Just in time your lease ends, so you renew contract and get new model.
Ah yes internet rambos. Never driven one, no sorry sat in one but endless talk. Listing some things and then saying: wow mist be unteliable
Just stfu
Vy make a car last beyond zee lease period?
The Ballbearing Turbos are not that unreliable anymore.
One of your best videos I have seen to date - Amazing Merc Engine... 416 HP out of that little 2L is looney tunes! (And people ask what F1 does for road cars...)
Also, TURO is awesome - I have been using it for 5 years now and its AWESOME!
Another note on addition of PFI: it is very difficult to get a DI-only engine to meet soot requirements as there’s often a lot of trapped fuel, so a side benefit would be better performance on PM emissions. Also, PFI generally handles low load conditions (idle) in a much smoother fashion than DI.
It’s crazy how much advanced tech goes into the modern ICE!
Right after I heard the words Turo I was expecting to hear about its quirks and features.

One in the rear as in porche that powering the rear wheels . How about that
I enjoyed this video immensely. I appreciated your excitement about this engine.
Excellent - you really are the best lecturer out there, thank you. Did you mention improved mpg?
h bethune watch the video and check if he mentioned it
I think he only mentioned increased low load fuel efficiency, cylinder walls have less fiction.
At this point I am assuming Mercedes said nothing about MPG and therefore the difference is marginal or not as good. The engine would seem to be more efficient, but is generating a lot more power. I am not an engineer, but it seems the basic answer is what is greater the increase in power or the increase in efficiency?
@@Paul-pj5qu Well power itself has nothing to do with efficiency. Depending on what you're comparing the power increase to, it's probably higher than the efficiency gains.
On the other hand, just an increase of say, 5 mpg, is a lot.
It would be somewhere in the ball park of 1600 grams of fuel per minute at full RPM.

K20 with cheap ebay turbo kit: im About to end this mans whole career
Furries are disgusting with low boost making 350 whp
The keywords are "production" and "luxury". If thats not for you, then K20. But people making enough money for an AMG dont have time for that hobby, which is why they hire us to maintain their cars. All about balance and options.

Really happy to see port injectors, I hope MB adds it to more of their engines.
People say it's just 30psi of boost but something most people don't know is you can run this engine on 91 octane which is mind blowing with these kind of pressures
But didn't Mitsubishi make a 440hp version of the Evo X ?
Did. And, sadly, past tense is very meaningful here...
Yes in the FQ440
Its a tuned engine. Tuned by UK ralliart.

When you got to 8 minutes and was talking about the cylinder coating I was reminded of GM and the first Chevette engine with cylinders that were Teflon coated. They were a disaster. 10,000 miles and the customers were pulling into gas stations and saying, "Fill 'er up with oil and check the gas."
ladamyre Mercedes is using this Nano slide technology on all of their engines since 2013, the previous a45 had it too, so it's really not the first time they do this. Also the Teflon coating is something entirely different.
@@AOTanoos22 I get it. I'm not complaining or criticizing, I just thought of it because I'm a retired ASE master Tech who was trained at the GM Training College in Atlanta and there are a lot of stories about the Chevette. That car probably cost GM a million future customers who will never, to this day, buy another GM made car.
@@ladamyre1 yes i understand, thats very interesting as well
The Abarth 233 ATR 18S 1,759 cc Inline-four engine combined supercharging and turbocharging. The engine generated a maximum output of 490 PS (360 kW; 483 hp) but some sources even claim that the engine was capable of generating 507 PS (373 kW; 500 hp). In 1985, when Lancia engineers tested an S4 engine under extreme conditions, it developed around 1,014 PS (746 kW; 1,000 hp) at 5 bars of boost pressure.
They should make a V8 version of this engine, with 800 horsepower.
It doesn't typically scale like that.
@@nickmotsarsky4382 unfortunately
xdygmnyrdf me i want inline 6 between 150-200hp/l
Inline 8? Lol
Eman7335 4.0 double i4 quadturbo. They should hire me in the marketing department
Mitsubishi had 2 liter with 400hp over 10 years ago and nobody bats an eye, AMG releases 400hp 2L engine in 2019 and everybody lose their minds...
it only worked for 50 miles wasn't reliable at all.
People are blinded by brand names
AMG is over 400hp past Mitsubishi
I'm pretty sure people were stoked about the FQ 440 back in the day, I know I was. Just because something is current doesn't mean it has more hype.
Yeah they are talking so much about that engine because mercedes started boasting everywere. Saleen is much smaller company and not so many people heard of them and they are not boasting about their 2.5L in house developed engine for the Saleen S1 450HP.
Honda never slapped turbo on the s2000 i belive it could reach easly 400+HP, 240 NA.
Insane progress from Mercedes, throwing everything at it
First thing to do on every of your video is to click the Like Button. Such high quality education.
Love it greets from Germany.
... als deutscher Ingenieur im Fachbereich Motorenentwicklung stimme ich dem absolut zu! Wir habens sowas von drauf, daß wir drauf SIND, haha...
No, seriously - I strongly agree with this.
30.5psi. great. engine will be done after 50k miles
Interestingly enough, many diesel engines have peak cylinder pressure about 200bar, and they last for many many miles. This one is at 160bar, Mercedes could make it long lasting if they wanted to. But instead, the cylinder is made from aluminum, coated with some smartass coating. And the piston skirt is of minimal size. So yes, this engine will wear out quickly.
Haha thats like a dollar per mile till it goes boom.
Let's not get crazy here. If anything goes on this car it'll be the electronics or something. I'm sure the engine will last at least 100k
at least its not a diesel PSA engine ahahah
@@xdygmnyrdf smartly made coatings are not necessarily bad. I don't understand why the car world is so averse to these new coatings, and new technologies. For people that have embraced things like turbochargers and torque vectoring, why is it that technical and non mechanical stuff like a chemical coating scares you all so much!?
Just like you can retool or machine new parts you can get stuff re-coated, if the coating wears out.
That engine compartment looks like the Hieronymus Bosch painting "Hell".
all I gotta say man is keep doing what you're doing, the people need your content to make it through without having to sift through a boring article about Mercedes to find what they want.
Really enjoy these technical videos, you don't get this elsewhere.
Motorcycles engines(sportbike) have been making over 200 horses per liter(normally aspirated) for years.
Yep, they are reliable and incredibly cheap compared to this engine. I was expecting something that can reach at least 300hp/l like a NA 2 stroke
Because motorcycles are light, they only need little amount of torque to get going. They will make great power at high rpm, but no torque down below. It's a different approach.
@@bigpig187 If they are going to talk about the most power per liter street engine then that award goes to Kawasaki's H2R at 326 hp per liter. But that bike really isn't street legal is it? But a 2 liter version would put out 652 hp. Just sayin'.
@@dman09191964 Yeah, but the H2R isn't street legal. for race engine i think that the NSR 500 is still on top.
@@bigpig187 You are right on both statements. The Mercedes engine is nice though,for a car engine. I would love to drop that motor in my Ford Focus ST,which only puts out 252 hp stock. But when it comes to engines I am all about sportbike motors. Just amazing pieces of art to me. Just waiting for Suzuki to unveil their new 280 hp(I'm guessing you know) Hayabusa to the world. God allowing that will be my next bike. My ZX14r is feeling a little slow compared to these new bikes
Phew, 54k for the CLA45? Hopefully we see continued innovations like these, so that these engines may become more accessible. I'm sure we'll see more of these pop up in European drifting as time goes on.
Yeah, that's actually reasonable in my book. I was looking at a mercedes dealership job, and the prospect of owning one of those was intriguing.
BMW M50 is good engine for building power on a budget in Europe.
Only if the engine survive the first 2 years of leasing. Those cars are getting fucked by their owners. You get special leasing conditions if you work for Mercedes Benz in Germany.
No car guy wants a leased car because we all know these cars are done.
@@ristekostadinov2820 definitely a good engine. Is a saw a fully modified e30 with an M50 with over 900hp on the Hockenheimring.
shame the a45 and cla45 look like a chav edition merc
Don't let this distract you from the fact that Hector is gonna be running 3 Honda Civic's with spoon engines. On top of that he just came into Harry's and ordered 3 t66 turbo's with NOS's and a Motec System Exhaust.
I think everyone needs to remember that boost pressure doesnt blow motors, excessive cylinder pressure does. Merc just managed to efficiently run 30psi on their engine with a lower cylinder pressure.
For e.g. On my personal build, i was running 2 small turbos at 20psi which dropped to 18psi up top.. although they were rated at 22psi, the turbos werent holding boost all the way, the wastegate actuator kept pushing open. A blanket fix would be to just fit an EBC and get it to maintain boost right? Wrong, the reason the gate opened up was due to exessive pressure from front/dump pipes being too small. If i was to just increase boost uptop to compensate, my cylinder pressure would have doubled, despite it being the same boost level. No one EVER seems to talk about cylinder pressure when modding/tuning cars. This is why you end up bending rods, stretching heads etc..
You need to change the title to most powerful *production* 4-cylinder. People out here making 1000hp+ on honda k series engines
He says it in the first ten seconds... .
Still a misleading title
310kW 500Nm (157.7kW/l) for those used to sane units.
Amazing video!! thumbs up for you and thumbs up for Merc for giving so much thinking on their engines, I meant this truly is race engineering applied on streetcars.
This video reminds me my 2004 STi back in....2004. I had this man in my college class with a 2002 Mustang GT. I told him my car is making 300 horsepower and he asked what kind of engine it has. I replied with, an H4 turbocharged engine. He got into this rage/denial and said there is no way a 4 cylinder can make that much power. I brought the official car brochure to class and showed it to him. He never really spoke with me again.
Looking at this M139, it is making the same numbers as my Lexus 5.0L V8.
Forged pistons + dual-scroll turbo + two-stage fuel injection + high-tech cylinder liner == *EXTREME* (ly expensive).

@@justanotherinternetexpert7743 all while meeting current emissions and regulations. Complete with factory warranty. That's what's nice about it.
Sure you can tune older engines and will definitely make that power but it won't have the efficiency and meet current emissions regs.

Who does not at least appreciate Mercedes tech? I Was looking at the 2018 CLA 45 AMG; went for the 2018 BMW M2. Slightly less power but a throwable little 2 door, similar price point. I have no regrets in this decision.
You did not mention it but for the record, in this engine, the cylinder head is cooled by a separate coolant circuit and the crankcase is cooled by a different circuit. I could be wrong about which circuit is used to cool the crankcase and the cylinder head but I think Lower temperature circuit is used to cool the cylinder head and high temperature circuit is used for the crankcase. So, the circuits are different which help in structural integrity of the engine. Secondly, it improves the thermal efficiency of the engine by using higher compressor ratios. It is possible to use such higher compressor ratios because the head is now much much cooler
Hadn't Mitsubishi a 400bhp engine years ago in the Evo. The FQ400. It was 2.0ltr also.

The H2 is street legal in USA. The h2R is not street legal,and has more power.
What's even more great about that Nanoslide liner on your cylinders is its guaranteed end of life cycle taking you back to the dealership for more maintenance or a new car. Then again, you bought a Mercedes so you are quite comfortable with the idea of having your car in maintenance.

@engineering explained I just watched your "Open vs Locked Differential" from 2012, and to this, I just made it to 0:24 before I noticed you are WAAAAAAAYYYYY more passionate 8 years later haha!
Open deck engine blocks are designed that way for ease of manufacturing. That is, they can be cast in a permanent mould without the need for a sand core for the water jacket. Closed deck blocks require a sand core to form the water jacket, but that doesn't mean there's any compromise in cooling performance.
how about reliability? until this is proven I still have more respect for the naturally aspirated Honda S2000 engine - I know a few that have over 150k km, no major issues
It is a Mercedes, mate. Reliability is their surname.
There are a few Mercedes vehicles with MORE than a million km on their counters, just with the needed replacings and maintenances.
Those are diesel.
@@torrhthc4103 wrong. There are a couple of them which are gasoline.
We have one here on Brazil.
@@arthurhenriquemendesberte2228 *WAS* their surname. Nowdays it's all about keeping the market fed, ain't nobody got time for reliable cars that last past 10 years or past 250k km.
@@ttltm funny thing, most of Mercedes cars I see these days get that reliability for sure. With basic maintenance, oil changes and such.
If you keep it running as Mercedes tells you to, it last ages.
My GLA45 has been making 440whp for the past 3 years. It’s my daily driver. Best 83k I’ve ever spent.
Healthy Human yea me too!!
Nanoslide? Another slick video is what 'twas.😋 Thanks again, Jason!
Really is kinda nuts when you look at cars like the Stinger or G70, which are awesome, but they’re using two turbos on a V6 to make roughly 50 less hp. Crazy.
now if only they can make cars that dont fall apart so soon
planned obsolescence amigo..
Nope.. Their just trying to make a sale.. most people will be trading it in 8 months later when the new one comes out..

Aftermarket tuner cars... am I a joke to you?!
Lol Jk, I know "production vehicle".
“Over 200 hp per liter”
Car guys: 🤯
Bikers: 🤷♂️
Holy hell.. I used to own a 2015 CLA45 which I added a piggy back ECU which upped the output to slightly above the new engine's output. The problem was the car had an early lag when stopping on the gas and the ECU changes didnt help at all. All these changes with the new engine address that. I eventually fixed my problem by buying a 2019 AMG C43 which has a twin turbo V6 lol.. And then got that tuned and has nearly the same power as a hellcat now.
Hmm. Nothing to worry about long term reliability in an overstrained 2.0l I4 cylinder engine with over 200HP/litre...
Nothing to worry about.
It is a Mercedes engine, mate. These things endure hell and keep smiling at the other end.
Mercedes F1 engines are 1.4l V6 turbo engines, with double that power, and they run 7 complete GP's before needing to replace.
7 GPs means that the engines are good for at least 170k km before needing attention, besides basic maintenance.
Arthur Henrique Mendes Berté Though Mercedes isn't what it was 20 years ago. Before you could get a luxury performance vehicle without having to worry about reliability issues as much as with Audi or BMW, but nowadays MB have become more and more dependable.
Probably they are still much more reliable mechanically than they are electronically, still more than BMW and Audi.
I just wish someone would pump that much boost through a high displacement, dohc V8
Koeniggsegg?
Beat me to it
The Indy Cosworth V8 2.65L tried but had difficulty finishing 500 mile races if boosted above 750 HP. The Offenhauser 2.65 L 4 cylinder, on the other hand, ran reliably at 1000+ HP, as the simple 4 cyl was anvil-tough and totally reliable. By the mid-70's the Offy's were rule-booked down to less than 800 HP, plus not allowed to upgrade to electronic fuel injection, so that the Cosworth V8 could "win" by the better efficiency of its electronic fuel injection. The Offy's could still dominate the Cosworth's during a race, but would run out of fuel and not be able to finish the race. On a level playing field, the Offy 4 cylinder literally blew the Cosworth V8 off the track!
It's called pulse turbocharging which is better than constant pressure turbocharging when it comes to giving turbo boost but it's lower in efficiency as compared to constant pressure. the cylinder liner is deep honed.
Guys the Brand is Mercedes, it's not any other car brand, they perfect in what they do, they know what they are doing.
mercedes: we got the most powerful 4 cyl engine
honda: *laughs uncontrollably*
mercedes: in a stock vehicle
honda: there are civics from the early 90s wich their original motors tuned to put out 600+ hp lets see how long yours will last
mercedes after 10k miles: *explodes*
HECKproductions haha. I was about to say, Ive seen a few 1000 hp civics.
gang gang ..what a production Honda..?
It's the turbo that's getting them the impressive 400+hp. BFD for that kind of money.
WOW, you're so clever, do you work for MB?
Wow you're such a clever , judgmental douchenozzle . MB doesn't use turbo they use Kompressor. Every German car snob knows that's a lot better because it takes twice as many letters to spell it.
I drive a 2018 Mercedes Metris cargo van with a turbocharged 2 liter 4 cylinder, and it moves like a strong 6 cylinder. Very impressive and it has exactly half the horsepower of the engine he's talking about here.
So oil sticks to the porous new cylinder coating. That means oil gets in the combustion area, and... burns.
Customer: I have to refill 2l/1000km.
Mechanic: Yea, that's just normal.
I LAUGHED SO HARD!
2:49 can you explain, how a ball bearing has less friction than a slide bearing?
Less contact, less friction. Ball bearings are rolling in the bearing housing as opposed to journal bearings sliding against each surface ( even with a film of oil ).
You can feel the difference with your fingertips by turning the compressor blades of a ball bearing turbo against a similar turbo with a journal bearing!
@@petergordon4525 I get it. The starting torque ( when the turbine starts spinning) is less than in a journal (?) Bearing. But a ball bearing can't spin as fast as the other bearing because of friction.
How long will the headgaskets and connecting rod last you think?
Yes, these engines do not seem to be made to use you car like an Uber. If you beat them (and 400hp ask for beating) probably ar engines for 50k miles
The best bit is the reduction in friction via TWA, the rest is old school revhead stuff, big boost, big valves, big fuel.
Factory air to water intercooler = win. Nice job Merc.
I wonder how that cylinder lining holds up with miles though, cause it sounds too good to be true
I would like to thank you for this video, i was looking forward to see it. Thanks 🙏🏻
The Evo X FQ-440 made 440hp at 6800rpm and 412 ft lbs at only 3100rpm. It was a UK only model but its still a production car. It had a warranty an no you don't need to rebuild the engine every x amount of miles like some idiots say.
120 hp / liter of displacement is what Honda got you 20 years ago.
208 hp/liter of displacement is what BMW get you 20 years later with 3 times more intake pressure lol
Please give drive pressure vs boost. I’m curious to REALLY see how good they engineered this powerplant. Admitting port injectors are to deal with intake valve deposits goes against “best or nothing” speak. Let’s discuss Nanoslide after a rad hose spits off while underway......
Port injectors also increase the amount of time that the fuel has to mix, and increase the amount of fuel that you can inject outright. Many high performance engines, including aftermarket setups, use both at once. The fact that the port injectors remove intake valve deposits is a nice longevity bonus so it makes sense to mention it.
Ryan Crosby plus reduce intake air temp through latent heat evap
But, the FQ-440 EVO X made more power in the UK !
Yep, hence the word currently haha. :)
Your right, 220bhp per litre.
He’s American so??? ten seconds research is a bit too much.
Lesser Spotted Mugwump. I don’t think that comment was necessary. The evo x isn’t in production therefore it is not the current fastest 4 cyl in production
I love those diagrams. This info is way above my pay grade and I’m guessing you attended all your classes in University. Some super impressive numbers coming from this engine. I remember when 1 h.p. per cubic inch of displacement was a big deal but over 2 is amazing to me. I think if I had had teachers like you I might have gotten through high school.😬👍👍🇨🇦
That's impressive. It's interesting that the 2.0l mark seems to be a sweet spot for pulling hp and efficiency out an engine.
Kawasaki H2 1 liter motor produces up to 326 hp.
@@buckybucky8596 1.6l formula engines pulled 1200hp back in the 80's.
@@debunkthejunk1 V6
@@buckybucky8596 Regardless of configuration, 2l of displacement seems to have proven itself the sweet spot for passenger cars in terms of getting a good hp to weight ratio and the reliability consumers have come to expect. Larger displacement tends to be wasteful and smaller engines don't seem to last as long. Of course this is relative, a modern 2.0l engine would have been more than enough hp for a passenger car 20 years ago.
25yr old 4g63's are laughing hysterically!
Impressive indeed, but truth be told, those, SR20DETs and alikes from Japanese crazy turbo cars of the 90s did it too but with very low compression and thus mileage on normal usage is quite terrible, not to mention emissions nowadays are another story
@Nick Volkov "280hp"
yeah let's believe their claims
But yes the turbo lag was there indeed
4g63 are... wait for it.... waaaait for the turbo.... laughing hysterically !
Jenning, shut up you don't know what you are talking about
@@Kalvinjj sr20 is over hyped and b series from Honda are cheaper more available and just as strong if not songer in most cases not to mention aftermarket support and bulletproof trans 🤷♂️
The 4-cyl turbocharged engines MB has are excellent, also very well balanced.
@Sandy Lee Clearly you have not driven a modern MB 2L turbocharged. - silky smooth.
@Sandy Lee Of course they are balanced to counter the natural imbalance. The point is MB does it extremely well. Power loss? Sure, but I am perfectly happy with the end result. And yes I have driven 4 cylinders from the '50s and I tell you... they were fun too! Fun can be found in many places.
30.5psi boost? Wow. My 15L Detroit only runs 32psi at max boost.... I can't believe the little turbo on this engine can push that. This little four cylinder is amazing!
Man this thing will be running HOT
Amazing power, what about reliability?
Yoseob Yang mercedes is usually good with that. but so many electrical components with the mercedes, everything ain’t gonna last 100k 😂
Keep your fingers crossed..
30 PSI. That was epic boost years ago. Now, manufacturers are doing it. Awesome, how long will those engines last? Hmmm?
ricky v at least for the warranty duration
@@gwagb27 That's what the warranty is for yeah.
Quite long, you saw all the strengthening to the block...
Jingle YaBombz I agree with you. It is a Mercedes Benz engine. (:
Mercedes and Toyotas don't meme short lived engines.
Naturally Aspirated, or Super Charged engines are more reliable. Turbos are connected to the Down Pipe, which is connected to the exhaust system for back flow pressure to spool the turbines. Back flow coming from exhaust leads to Carbon Build Up Check Engine Light turns on at 38,000 miles (after manufacturers warranty)
Thus, locking Turbo Blades and internal veins, restricting air and boost. From my experience I learned the hard way, it was great for
3.5 years (after factory warranty ended) fuel mileage average was
32 mpg and dropped significantly to
8 mpg to 12 mpg. Good luck with your Turbo replacement.
This guy is like a college professor I never thought I would actually pay attention to a board be so interested and learn. The future is here we just don’t see it. Internet could be a way got education
I see someone with engine problems and say " been watching too much engineered explained".
In a racing application that would go to the 80s bmw f1 engine. 1500 HP out of a 1.5 litre engine. That’s a 1000 HP per litre! FTW!!!
375 hp per cylinder!
I'd drive a 375hp 1 cyl car
I like how most of this comment section is just laughing at merc for coming up with a 416 horsepower 2 liter inline 4 that came out of the factory like this and then comparing it to modified 4 bangers that, admittedly, do make more but aren't stock. If you people don't understand this 400 hp engine is bone stock, that's not merc's engineers' fault, as they did a better job than anyone else in the world did when trying to design the most powerful inline 4 to come out from the factory.
Basically... Mercedes AMG figured out Audi RS team was right all along, except for the boost.
Obviously, there needs to be more boost.
Can't wait to see the first ones blow up.
no, it needs more cowbell!
Awesome breakdown. You have great content. Thank you for your efforts.
