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.
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.
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.
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
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.
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.
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
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.
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
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.
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.
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.
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'.
@@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
In the Middle East we have 6 cylinder Japanese engines with 2000-2500 HP... They don't last long... You're comparing a reliable engine to one that will be nothing more than a piece of junk in a run or two...
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! 😵
@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.
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.
@@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.
@@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.
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.😬👍👍🇨🇦
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.
@@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.
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.
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.
I got that power from my 944 turbo years ago, the 944 turbo I have now has 320ish with just a k27 turbo. Got that power from my Turbo Focus with a bigger turbo, tune, and intake. Had a 460 hp civic 5 years ago with 27lbs of boost. It was a custom h22 build turbo build. Lots of cars would pass this if given 30lbs of boost. AN S2000 with 30lbs would be like 600 plus horsepower if tuned.
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
@@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 🤷♂️
But the i4 engine with the best hp/l is an engine made by Kawasaki for their street illegal motorcycle, the ninja H2R which has a 1 liter supercharged engine witch makes around 310 horsepower... so a bit over 100hp/l more then the m139... also the bike is the fastest thing in a straight line u could buy for under 100k even beating an f1 car in a 1/4 mile race... too bad its illegal to ride it on the street... but at least we have the normal h2 which its engine is still supercharged and makes like 240hp i belive...
@UCBLpX-rZodBoM7G6JZYF5iA everything u said is kinda wrong... the h2r might have a lot of power but it isnt the best in the corner... definitely can not be compared to any motogp bikes... also the h2 makes 230hp... we were both wrong... also the a45 starts at 45k dollars... sooo like 5 grand less... but its a car... people wont buy it without adding options sooo... lets say they are the same price wise lol...
Also if u die on a bike its ur fault... u didnt see a guy run the red light, ur fault that u died because u didnt pay attention... its a survival of the fittest... or in this case... survival of the smartest... u know how to ride defensively (this should also apply when u drive but whatever) u wont go down that easily... if u dont ride like a maniac then u wont lowside and get hit by an upcoming car... if u die or crash on a bike its because of ur own stupidity and incompetence
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.
You are awesome man! You made me more confident in getting my automotive engineering degree! Wish you the best and I hope we will meet in the future :D
The twin scroll likely results in reduced low end torque and the wider spaced pulses on a single inlet would likely spool up the turbo a little faster. Since the peak torque is lower than the peak HP, it means the bottom end is a little soft typically. Torque remains high above 5000RPM. Larger exhaust valves also hurt low end RPM, but VVT will get some of that back.
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 you mean the engine was rotated 90 degrees, not 180 degrees. That arrangement would put the output flange on the front of a longitudinal, not laterally-located engine.
@@fidelcatsro6948 actually it more like a trap.... lure you in with nice sexy car and take all your money will all you got.. i just see brand new one that headlight already broken..
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
Mercedes: makes 200+hp/l with over 3 atmospheres of absolute induction pressure, special coatings, direct injection and other engineering voodoo. Aprilia: laughs in 2 stroke smoke.
4g63 can hold more boost. 6 Second passes proves this.. This motor is planned obsolescence and designed to cost the owner money. How do I know, I work for MB.
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
WOW, some of these comments leave me speachless. Some have no bearing on the video, others prove they didn't even watch the video. In any case, I remember the hype over the old Lotus Esprit 4 cyl at 280. I wonder what the tuners are going to get out of this engine.
Roller bearings fail catastrophically. Journal bearings typically survive a catastrophe, as long as there is flowing lube oil. In my mind, I imagine the difference in contact surface areas and localized stress of the bearing components (journal vs roller bearings). For automotive applications, it doesn’t “really” matter that much either way. I don’t think pragmatically, I think like an engineer.
What I am curious about, is how their "roller bearing" compares to the advantages provided by the "ball-bearing" design that has given Garrett's turbos a distinct advantage over journal bearing turbos. I'm currently still finding ways to expand the "limits" of my GT3040 (aka GT3082) turbo (oil + water-cooled BB turbo), which I installed in 2003 and have never had to rebuild it. It provides 450whp currently on my 2.2L stroker 5sgte, and spools to 200 ft-lbs by 3000rpm... and that is only at around 23 psi... not done yet, it should make over 500whp by the end of this year.
wasn't there a 1.5 liter inline 4 bmw engine from the 80s that could get to 1500 hp. It was only used in a 1500 hp configure during qualification and not during the actual f1 race
IIRC the most powerful production 4cyl was the one in the UK only Lancer Evo FQ440, 440hp and 560Nm of torque... from a 2l! Granted, it was some years ago (less emission sh!t)... so it’s good that a high specific power engine could still be made in 2019
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!
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.
@@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. Not everyone wants to buy a car to tune it, some like to have a car with that performance out of the factory. These aren't designed for people that buy used cars only tbf.
Haha true! That why Toyota/Lexus keep their bhp proportionate to increase engine longevity and reliability which is why I will be getting rid of my Audi A4 and it’s engine problems (oil chain pump failure, leaks etc) for a Toyota/Lexus in the future.
Yea okay let's wind the boost up and claim high hp.......One thing I'd like to know is how long would this engine last compare to the other 4 cyl engines
@@commanchi7 This engine won't run at max power for a long time. An A-class needs about 150 kW to reach 250 km/h, which is their built-in limit. Very few will take this out somehow, some will, but still it isn't likely many of these engines have to run at 300 kW for hours and hours and hours - and, inside the engine, this all translates to forces and thermal stress, which can be calculated and stuff can be built to resist the expected forces ... like, the connecting rod looks different than the one from a 200 kW engine ... all bearings will be pretty big ... cooling is optimized ... That's not that much of an issue. Of course, using the full power permanently leads to higher wear and stuff, but if it is built like it's state of the art - this engine will live long. ... in these regions of high specific power, the compromise that is to be made sacrifices a bit of efficiency - would be more of a concern to me.
LANCER EVO FQ-400: 400hp 2.0L: Seen. EVO FQ440: 440hp from 2.0L: has left the conversation. Mitsubishi did this like more than 10 years ago, and did it while keeping reliability.
And Honda made 240hp in the s2k without the use of any turbocharger back 20 years ago. People are flipping out because this is some bs peoplemover car. Mercedes doesn't make a single thing that excites anyone, so this, well, they jumped on this
@@robeley514 they are making nothing that excites people anymore?????? Ok, then why are their sales so high, and why are their cars so damn popular everywhere in the world? In 2018 they sold 316 thousand luxury cars in the USA alone, more than BMW and a lot more than Audi
@@brunobegic3841 Only 64 McLaren F1 were built, so that shouldn't count as well :) It was (fq 440) a factory car, you could buy in dealership, with warranty --- so it counts.
Well done, Jason and i was gonna comment about Mercedes reliability but it looks like several others have beat me to it. North america and Mercedes just don't mix.
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.
