So the my question is, is the high pressure injection good/reliable, or an expensive disaster waiting to happen?

BMW's B58 is the best current ICE imo.

I have to disagree on the drag race analogy. If you only had one gear it would be correct. The transmissions would be the difference. Diesel would shift sooner, thus keeping it in the optimum power band.

I like how mercedes made their engine feel more like a naturally aspirated engine by making it more complicated

BMW Valvetronic and VANOS work in conjunction with each other

It was good to learn about the differences between the inline 6 engines of each manufacturer！☺️

Globally what is the reliability of GMC's those past 10 years for exemple ?

The Aussie Barra is a beast strapped with a turbo. I doubt these I6’s can compete with power

All three are unreliable!

wonder if you can modify the gmc at all

i dont want science... i want engine noises. fast forward, disliked video.

I stick with 4cyl diesel engines, Peugeot make the best. Registration is also cheaper.. The more additional boys put on the engine or car the higher the repair costs and downtime.. This can negate any efficiencies or cost savings from new technologies.. But, of you can afford it who cares.. Just offload the car and upgrade every few years and pass the problem on

The main problem with the GM 3.0L engine is that it is attached to a GM transmission.

Great Videos Jason ! Thanks For Sharing Your Knowledge & Research !

This all fine and good. You have explained all the gadgets connected to the engine to improve performance. You have also explained that come back of the six is due to the same reasons the v6 was created, in that it was a natural extension of the current manufacturing process. Do you have an a comparison or explanation of advantages of engine configurations and why?

Love these videos, very informative even for someone who knows a bit about the subjects, thank you and keep up the great work :-)

I hope GM is not making their own diesel. More rpm usually means more hose power.

...if someone set out to create a product that would be unexpectedly expensive , keep a variety of auxiliary businesses taking tons of the owners money ( like gas, spark plugs, air filters, muffler, transmission, gasket, fuel filters, waters pumps etc ), pollute the environment, and need to be totally replaced after a short period of time...they would have invented the internal combustion engine...it takes a real genius, like this fellow, to understand and educate us common people the likes of all these cars...but after listening to his knowledgeable lectures, there comes only one conclusion...after looking at the wires, pistons, flames and dirty oil whether the best 3 or the worst three....the days of the ICE machine are coming to and end real soon...

I own a BMW I6 N57 Diesel engine and this thing is smooth as butter. 90k miles on it. Knock on wood, not one repair..

You missed the main advantage of the electric motor on the mercedes engine. It is beltless.

Who drag races in a diesel pickup truck? The torque of the diesel engine means the pickup can haul a heavier load from a stop to the legal speed limit.

Electric motor helps speed up take off, then drags the engine while it recharges the battery . Mmm think I'll keep my cummings

Again an interesting video ruined by far to many ads .

No, power is not "what matters". In the early nineties, we had in Europe NA gasoline cars with low capacity and high rev ceiling and then direct injection Diesel engines came in the late nineties with lower power and much higher torque. Everyone swapped. Why? They are much faster in the real world, don't require high revs and due in part to the torque, consume a lot less. Even with turbocharged gasoline/diesel, a 150 hp Diesel tends to be much faster in the real world than a 180 hp gasoline engine. Of course that's because few people go above 4000 rpm in the real world.

You left out the best inline six of all...the Aussie ford Barra...we boost them up to 1400 hp no problem

Yup, the Barra is the king of the hill for i6 engines. A factory cast block and head barra can make >2500hp.

This man looks young and old at the same time

I want an inline 12 cylinder engine

so more torque the better to use the turbo charger than supercharger..

Timing system on rear of engine.. Do I need to say that again?

Hmm one diesel and two petrols...why not comparing apples to apples...let's say GMC diesel vs BMW 540d vs E400d engine...so diesels And the instead od GMC diesel it could fit a gasoline version here.

Why not using the AMG 53 engine instead of 450

That's sad. Gmc- which is all garbage post 2000 Bmw and mercedes- which make great machines with terrible electronic self destruct systems. Basically buy inline 6 pre 1987 From anyone if if you want something that lasts more than 100k

"For 2020" sad Ford 4.9l noises

best engine layout. Most balanced. In v must be at least a v8.

That B58 must be a great engine! Their putting them in the Lexus now. You go BMW

Another IL6 n52b25 is soo smooth and reliable. Linear power delivery

I bet that Mercedes engine is pretty awesome while its new. All kinds of throttle response I bet.

Why dont they use higher pressure on gasoline engine?

No mention of Barra. BMW and Mercedes repair costs outweigh their inclusion. Then again, 3.0l list.

Well done Jason - clear, concise and valuable.

MAZDA's 2.5 l. turbo also has a way to keep the air flow fast at low RPMs.

Barra!

Australian Ford turbo barra motor will eat these for breakfast and not even burp. 1000 bhp on factory stock motor is possible and Street able.

😂😂😂😂

RBX28DETT. From 2005. 178hp/liter in the R34 Nismo GTR Z-tune.😉

Interesting video, but as European I must ask, why don't comparing 3 diesel 3l in-line 6, BMW and M-B build them too

Mercedes will be the most expensive to fix!

Inline 6's are just cool. The sound can be amazing. BMW K1600...

A best straight 6 engine video without mentioning bmw would be sacrilege

Jeep's inline 6 4.0l

Buddy, only Americans needs super high HP. And other people love offroading more than top speeds. If you say torque doesn't matter.

All I wanted to know is who gets to the 1/4 mile flag first🤔....well?

Would you be able to make a short video about the low pressure turbo on the 2016 Volvo t5 ?

Your wrong on power.vs torque Power burns the tires off. torque moves heavy loads. A pickup needs torque not horse power . look at the 5.9 Cummins 12 v 170 horse power but can pull any thing you want. Gas motors suck gas and have little torque a 454 with 450 horse power only has 450 foot pounds of torque and. Can not pull heavy loads well a 5.9 Cummins with 170 horse power and 470 foot ponds will out pull it ever day of the week and use half the fuel. You need to learn about diesel engines son. If you have 6 I a line your good to tow 606 MERC. 5.9 Cummins Dt 466 IH 3306 CAT 3406 CAT EVER THING ELSE OUT THERE IS JUNK.

Power only matters in a race. If you mostly use your truck off road at low rpm then high torque at low rpm is king.

When did people start saying lb-ft instead of ft-lb and why?

Has anyone done the math to find how much CFM is lost in all the intake tubing and bends?

Good video - even though seems you're talking with a potato inside the mouth

barra, 2jz, bmw's I6

It is unlikely any of these inline six engines will last as long as the AMC 242ci I6 I have in my aging TJ. As of a few days ago, there is 411,500 miles on the odometer and climbing. The engine has not been rebuilt and has not had any gaskets replaced. I did tighten all joining surfaces two years ago to make the gaskets work better, but all is original, including the water pump and the infamous 0331cylinder head for the 2000 and 2001 years. I even overheated twice when I hit a bird and it ruptured the radiator. Compression is still good. The nearly legendary AMC valve rattle when the engine is cold has been with the engine since just over 200,000 miles. But once it gets to normal operating temperatures, the AMC rattle is goes away.

What about nissan vtc 4800 in patrol y61. That is one of the best inline 6 engine

Cummins 6.7 liter Diesel is the best in-line 6!

How does a twin squirrel.....

By far the best inline 6 engine available* in 2020 is the Toyota 1HZ. Fun fact: it has no check engine light so it can't fail :-). (*in some countries)

om606 every time

Why no cummins

Because he's talking about gas engines.

The Diesel also runs without a throttle butterfly valve. Like the BMW gas engine. Fuel to air ratio is what controls power output in them and is also what makes emissions control difficult with them, as I understand it. Does BMW use the same valve opening technique on their Diesel sixes? Who makes the GM Diesel, GM itself? Are all three engines roughly 3 liters displacement? Yeah, I'll go look at the Wards article.

You made this in January. What if someone came out with a better engine in February, March, April, May, June, July, August, September, October, November or December? People are jumping the gun to get a video out and get views.

Have you been to 2020? It's July and so far all that's happened is half of Australia burned down, the Arctic caught fire, a plague of locust destroyed Africa twice, the police started teargassing housewives, and hundreds of thousands of people have died from the plague. Nobody is making a better I6 this year.

ARABE BLEZ

You need to look at Australia's I6 engines. Ford had the SOHC 4.0 I6 and later a DOHC 24v 4.0 I6 (Barra) and came from factory with a turbo. Both are torque monsters

I love what you said about torque. That's what I never understood after all those years.

Not even halfway thru 2020 and yet we have the winner? TBH....I'd vote for the diesel motor simply because it's a diesel with better fuel milage. The durability issue is also to be determined at a later date.

Hey Jason, I would like to see a comparison between equal displacement inline I6 and a VR6, I want to be convinced that a VR6 package or VR8 package isn't the better configuration for Longitudinal motor placement in an engine bay, if the VR design has similar torque/power? Thanks

Really love your videos. One question: which engine is the easiest and cheapest to maintain? Ok those are two questions but it is why I love my cummins 5.9. I also have an e39 530 and love that engine too although more expensive and more costly to maintain than the cummins. I looked at the new GM in line 6 diesel thinking it might be easy to work on, but no, cant even see the engine with all the ancillary equipment.

N54 still purrs

Funny how GM has the most wins in Ward's Best, when GM isn't nearly as successful at the International Engine of the Year Awards. I think they are a little too "red, white and blue" at Ward's...

Very well explained, thanks so much

RB26DETT ftw

2JZ and RB26DETT is the legend I6 engine

So very interesting.

Mercedes E53 AMG 429 hp and 384 lb-ft. Why didn't you use that engine for comparison?

Until you factor in BMW’s and Mercedes reliability.

Bmw will always be the best. The most underrated brand ever.

Before watching this video I am gonna say that BMW makes the best I6 engines period.

GLS 450 4 matic 2020 Inline 6-Cylinder Spark-Ignition Engine, M256 is hybrid ?

I like German engineering, but I have a problem with the German marketing departments. I don't want to sacrifice all of my Man Cards on some limp-wristed fruit car driven by neurotic foppish dandies with more money than know-how. I'd like my girlfriend to be more high-maintenance than my vehicle, thanks.

The 6 cylinder bmw diesel engine is amazing as well

the Aussie built barra 4 litre puts those engines you got up there to shame

no inline 6 can beat toyota jz engine

B58 S55 N55

Hi Jason, Which inline 6-cyclinder engine would you personally rate as the all-round best?

“Once we get this in to its higher RPM region, it’s done. It’s going to stay ahead for the rest of the race forever, because it has more power, and power again is what matters” Unless the race is over. Consider 0-60 drag races between F-150s with 3.5 EcoBoost (375 peak hp) and 5.0 Coyote V8s (395 peak hp). The power of the V8 doesn't exceed the turbo 6 until nearly 5000 rpm, by then the race is over. The V8 would probably win a 0-100, but that's not legal in the US. Separately, it would be great to see a video explaining why an F-350 dually with a 475hp diesel is rated to tow so much more than the same truck with a 430hp gas engine.

Jason if power mater's more than torque?why are hybrids the in thing in hyper cars, electronic motors have instant torque,and torque is the reason all trucks run diesel engines,

God Jason, your videos are so interesting to watch. Very well done. Super clear.

Jason + 2 feet breaker bar = 2 jason-feet of torque

RIP The mighty Barra!

For me, I'll take an electric motor.
