The Best Inline-Six Cylinder Engines Of 2020

torque being the meaningless number when hp is based on the torque number and the only number that's measurable. a ford 300 i6 doesn't go fast at 95hp, but it'll pull your damn house down at 250lb feet of torque. the reason you can output 200lb ft of torque on a torque wrench is length. try putting 200lb ft on something 4 inches long. good luck. torque absolutely matters the most.

No mention of the utterly unkillable inline ford 240/300......

How we have fallen.

I have a doubt. Out of these 3 engines, the GMC Sierra has lowest stroke. So ideally it should rev higher than the other 2, and should produce high-end torque (correct me if I am wrong). But still we see that it revs only upto low rpm (as compared to other 2) and produces low-end torque. Why is that?

To me the best inline 6 will always be the GM 250, Opalas here in Brazil pull over 2000hp in those engines.

Me with my ford falcon laughing in Barra ...

A diesel with variable length intake runners?

Your forgetting the ford barra turbo

I couldn't help but notice the Jeep 4.0l inline 6 was not on this list

"The same style... but very different styles..."?

Ha, interesting...!

what a waste of time...buy an EV...much better performance.

You can not compare diesel with gas engine

They should have put the bmw b58 in the new Toyota Supra. The original Supra had a turbo inline 6. This engine is much better than what they've got in there.

The I6 engine with the48VDC electrified water pump and EQ system I think is the best. with the soft hybrid system it makes 435HP.

Jordan Peterson says that is not power that matters but ethics

hehe, I just paused the video to say 5252 is the number of not using metric system

Please stop pretending gm had anything to do with that diesel engine

Mercedes is always the winner and bmw follows. 🏁

The B58 is the best overall inline 6 on the market, IMO. It's one of the 3 or 4 best engines BMW has ever put in a road car. It pulls like a big block from low RPMs, is silky smooth, efficient, and makes great power all the way to redline. It also sounds fantastic.

Curios why the gmc engine was nominated instead of b57 which is better in every regard.

Cummins 6.7

IMHO, the BMW B58 inline 6 has the sweetest sound of any engine not a V8. Stellantis is supposedly building one.

B58 is a great, reliable and fun engine.

This hasn’t aged well for the gm i6. I’m a Toyota tech at a Cadillac/Toyota dealer and the gm techs here hate those engines and we’ve had plenty come in blown up because the cooling system is junk and they regularly fail before 5k miles

Are those birds in the flywheel lmao

Power isn't the only important thing, torque is important for lower cruising RPM, it's easier to hold higher speeds at lower revs when you have high low end torque that's partially why desiels are so good for towing, you can hold speed at lower rom

The 220φ engine accelerates the ions confined in a loop to moderate the relatarvistic speeds, and then varies their velocity to make slight changes to their mass. The 221φ engine then moves ions back and forth to produce ions, thus traveling in a vacuum line, so please use cruise control on the interstate.
We could reliably get ~94% efficiency with a closed loop superheated steam system harvesting exhaust heat from a small jet engine and got just below 96% efficiency in some ideal test cases. The main limiting factors were that the discs had to be designed to stretch uniformly without distorting at ~40k RPM and that the gaps between the disks had to be designed for an incredibly specific set of operating parameters (steam temp, pressure, velocity, etc.). So it's important to use synthetic oil....

Oh, and here's the GMC engine, the end

It’s facts I raced a 2021 GMC Sierra pulling from a light in my 2003 325ci stock automatic, and I over took the GMC while it was switching gears I was shocked about the torque the truck had but ,, but i was thrilled with how strong the engine my 2003 bmw Has to overtake such a modern truck 😅😅amazing

You can not just compare engines at drag race like that by discounting the gearboxes.

Wards anoints these engines as the "best" based solely on specifications.
IMO the best engines are those that would have good economy, bulletproof reliability and ease of repair. I had a MB 250 with carbs that was hell for durable, easy to work on and decently powerful and only fair in economy. Now working on anything other than filling wiper fluid is a nightmare.
The current German engines are not known for reliability with many critical internal parts made of plastic. The GM diesel might be good but again the praise is for the specs.

Great Content.. My favorites without a doubt BMW's i6..

Damn.
BMf*ckingW.

"POWER IS WHAT MATTERS POWER!" 😅 sounding like Jeremy Clarkson

the firing order is the same of all three engine 1*5*3*6*2*4 and all inline six made anywhere by anyone in the whole universe is 1*5*3*6*2*4

HAHAHHAHA!! you said 420. lol

2jz is crying

Always will be a 12v cummins

ISG removes accessory belt.

Also the detriot needs no electronics just turn it over it starts it runs it works as opposed to modern stuff minor fault code and limp home just for a faulty sensor

Best inline six of all time detriot diesel 6- 72, it can be built clock or anti clock rotation exhaust on left or right and blower on left or right, can't do that with any other vehicle engine post 1980

The best inline 6 ever built was the Ford 4.9 300 I6 those motors were almost indestructible low hp good torque however they could be livened up with aftermarket tubes or supercharger

The m256 from Mercedes will decimate all I6 engines if a company would but some R&D into its performance. The deck is open but never seen a design like theirs.

The BMW staying upahead in a drag race I find the Holyghost fellowshipping with me about during my first year in college pertaining to a drag race and it's two lanes being prophetic for the left membrane and the right membrane. This in me pursuing a BA in Psychology. Terrill TC!

Defense End I find prophetic for Desiel Engine. Terrill TC!

Pass the eyes into the engine a prophetic pertaining to the infinite between the eye gate and ear gate comes to mind here. Pass the prophetic for Psychologist Terrill eyes into prophetic for T(e)rr(i)ll. I find this in fellowshipping with Jesus Christ when I was in 2nd grade. Terrill TC!

The B58 is burning oil like no other

m256 doesn't fit in a c class, so it's as good as a bag of trash as far as I'm concerned... Bring back the V6 you twats!

You want a high Torque engine at a lower RPM. For towing and fuel economy. So that GM in line 6. Is a great economical work engine. Notice the GM pickup is not built for speed. Just low end power.

Isn't it sad how there are only 2 gas inline 6s in production?
