Same here my i6 brothers. My 96 jag inline 6 sounds amazing
My e46’s with the m54b30. Revs so nicely and is so smooth, even with one being at 167k and other at 122k. Love the layout and power delivery.
I wish more production cars used inline 6 engines nowadays.
Stellantis, the company that owns CDJR (Chrysler Dodge Jeep Ram) developed a 3.0 twin turbo i6 they're calling "The Hurricane" with SO and HO versions. That they'll be slamming into shit.
They won't because car designs are often size constrained. V-configuration engines are smaller in length and therefore easier to place anywhere under the hood without too much adaptation. If you'll notice they're pretty much only still used in the truck OEM industry.
@@peterinfamilyguy V-engines can also be shorter from top to bottom for a given stroke, further helping with packaging a larger displacement engine into a car design.
BMW still using inline 6 with turbo
bmw uses turbo inline 6 in their cars
Inline 6 is my favorite engine configuration. Perfect balance, flat torque curve, mechanically simple.
Inline has nothing to do with the torque. Stroke determines the torque.
The inline 6 Cummins is beast

as a guy with a ‘06 Ram with a 5.9 Cummins, the engine is a giant lego brick.
That's a good motor, though

@@helldoge best motor Ford ever made
When I worked in a city transit bus shop we could do a full engine rebuild with the block in the bus. Called an “In-frame rebuild”. It would take us about 32 hours, or 4 shifts.
An inline 6 is just a great engine.
The Ford 240/300 inline 6 is easily one of the most reliable engines ever made, no timing chains of belts, just a simple cast iron timing gear that will las the lifetime of the engine.
@@seana806The 2JZ was also a great straight 6 engine. 😎
@@applepoop10 overhead cam, more things to fail.
OHC isnt rocket science, theres plenty of reliable ohc engines out there. The issue is the 2JZ's usage of timing belts. @seana806
This is why when I upgraded to a diesel engine truck, I went with a Ram 5.9l cummins. When you pull heads off of an inline engine, and look at the cylinder walls, the cross hatching still is clearly present. I've seen the old 4.0 inline 6s in the jeeps with 200k miles on them still look like freshly machined cylinder walls. The straight up and down pattern wears way less than the rod angle of V pattern engines.
Not to mention there is less side to side pivoting at the Pistons as well as the crank and journals.
I am a V engine fan but the physics of an in-line just work out better.
Back in the day I did so many in frame rebuilds. Some even worked afterwards.
European trucks using V8s: “I’m gonna pretend I didn’t hear that”
Scania 770 V8 is the 16L torque king
And our trucks are length restricted and have V8 and I6 (and used to have V10 and V12 as well)
@@countcuda70 yeah they even sound amazing, but I'd still have a inline 6 volvo/DAF if I were to buy one.
Amazes me every time how the euro trucks pack the same thing into a package half the size of us models.
@@FerdinandFake US doesn’t have the same length restrictions and the bigger the hood is the easier it is to work on
The actual difference in rebuilding a “semi-truck” (class 8 truck) engine compared to a pickup is that the large diesel engines used in big trucks use a separate removable liner for the cylinder where light duty diesels and gasoline engines (even the fabled 5.9 / 6.7 Cummins) are simple parent bore designs where the piston rides in a bore in the block itself and the cylinder wall is the cast iron of the block itself, meaning that once the bore is worn enough to warrant a rebuild or a piston gets got and causes scoring the block has to be removed and over-bored on a mill regardless of whether it’s a V or inline design. That said up until a little over 30 years ago there were V engines offered in HD trucks, the last of them being the fairly popular 92 series Detroit diesels and the 3408 Caterpillar which is far less common. These engines used liners and could be “rebuilt” without removing the block from the chassis (an “in-frame” rebuild) and really weren’t significantly more difficult to rebuild than an inline engine, in some cases they were even slightly easier to work on in trucks with short hoods and limited space in the engine bay. The in-line 6 engine design ultimately won out though once length laws were reduced and stricter emissions standards were implemented, their advantages in longevity and ease of packaging ultimately outweighed the advantages of the V8’s, which were mostly related to size where space was limited and weight to an extent.
Inline 6s in my experience can get nearly the same type of fuel economy too I have a turbo 4 now but I used to have a non turbo inline 6 and it would average 30 mpg which is saying something cause I’m definitely not all highway miles
Ayyyy I got a turbo 4 too, what’s yours? I got an s3
My gasser v8 averages 33mpg highway on summer tires. I attribute that to a low rolling resistance, long gearing, and a .26 coefficient of drag more than anything.
@@bleachstain9785 My E55 AMG with 0.27 cd of drag and a 2.65 gear ratio is only getting 23-24 MPG on the highway lol. Probably because of that 2.1L supercharger on top of the engine
@@aimxdy8680 oh yeah you’ve got a half a liter extra displacement, on top of the 2.1 L of supercharger. It’s wild that the W211 E500 had a lower coefficient of drag compared to the E55 though
Okay okay you convinced me. I must put a semi truck’s inline 6 in a Miata
So, how’s that going?

Plot twist…still charge the same labor regardless of engien configuration
You just don’t understand how things work.
Try heat tanking that block while it’s in the truck … ( all that scale buildup inside the water jacket must be removed or you don’t have a viable rebuild it’s just something waiting to melt down again prematurely … LoL ..
Less labor + mass production = much cheaper costs
Exactly
@Robert Holderman ever heard of a steam cleaner?
straight six also has less internal friction, it uses less fuel.
Its tall as hell though man
@@TheAnnoyingBoss Trucks are not race cars.........horses, for courses.
@@TheAnnoyingBoss that's why slant sixes used to exist.
Blatant lie, you know nothing. What does "internal friction" even mean? Where specifically?
@@peterinfamilyguyot the poster but piston rings seal with what? Friction wow… so having less of them with the same amount of applied force making the same power means…. Less frictional losses there. Same for every bearing surface attached to the crank that moves as it’s getting slammed a few thousand times a minute even at idle from the explosions that are each cylinder firing. I can explain further if needed or you can think, one of those may even help you in the long run.
I love inline 6s
I will never sell my 96 f150 straight 6. Great torque.
Build a truck brand new but even better
I used to like the straight 6 gas engine for its torque, until it burned up on the highway

I have 235 straight 6 in my 1950 truck. Amazing engine, you can’t kill them
Backyard Miata looking around nervously
Well the fact that it has removable liners is the biggest factor that allows for inframe to be done
I was a Jaguar tech fpr many years, i had the pleasure of sleeving a 4.2 litre 6 cylinder that a wrist pin came out and cut a slot in the cylinder wall, didn't have to remove anything but the head and oil pan, got it done in under 8 hours
Doing an in-frame rebuild on a V-8 isn't more time consuming because the frame rails are in the way. It takes more time because there are two more cylinders and the crankcase is crowded with two rods per journal. Two heads on either side makes a difference too.
Mazda just released their CX-60 comes with a 3.3 inline 6 turbo diesel, really smooth and quiet, heaps of torque
Unless it’s a ford 300-6, you gotta lift the engine just to replace the oil pan gasket.
How often do you need to that? 300,000 miles?
@@ks_hunter7327 not exactly age is also a key point you can have 50k miles and start using it and everything starts leaking.
I love an inline six, they' re preferable to me over other configurations. I had a Mercedes-Benz with a seven main bearing M114 inline six, and it was so smooth. I put in new rods, mains and oil pump and drove it three more years after the rod bearings wore out. I did it in-situ. Piece of cake.
I miss my 1980, straight 6, AMC SPRINT, WITH A MANUAL TRANSMISSION!
Love my 258 straight 6 in my jeep. Plenty of torque!!
Depends on the cab we did a head gasket and it was easier to pull the the engine

We have powerstrokes, but they're generally considered less reliable and are much more work to service.

As a Skyline owner i see this as a complete win!
I grew up in an auto repair shop my father owned. We specialized in Nissan/Datsun Z cars which are in line 6s. Rebuilt plenty of L28s in car.
PERFECT ENGINE !!
Picked up a clean 96 Cherokee County with a straight 6 a couple years ago. Absolutely love that thing
Gotta love an inline 6.
I remember being a kid doing this with my pops I remember him putting the pistons or the liner in boiling water before placing them inside the engine
The DD15 in the truck I drive (so far) is a real champ. Love the way it sounds cold early in the morning. It's a bit of a dog up hill (governed) but so far so great. I'd only put a Cummins above these Detroits
That's a great looking block
Amen, just freshened up a 51 gmc. So much easier then other configurations. Appreciate all engines but dang this was super easy.
Each cylinder gets its own head? Wild!
depends on the engine. some are 2 per head and some are one large head.
Getting a fresh rebuild. 🎉
For MANY MANY years, Ford Australia had an inline 6 in their main family car, the falcon. Essentially the same block from 1979 to September 2016. I have a 2008 that is a DEDICATED propane engine, FACTORY built to ONLY run on propane. Incredible power in the thing.
I love the Straight 6 300 In my f150. Balanced in all directions
Always loved straight 6 🇬🇧🙏
The I6 is my favorite engine layout
Which is why my mom loves working on newer dd13 engines
That engine is massive, never knew they are that big.
And they sound sick.
Dat ! stress on the middle of overhead cam shaft tho 😂
Amc 242. One of my favorites and sad to say it was discontinued in 2006.
I love straight six engines, have owned 3 different ones ! Nissan rb, jeep, and bmw
All pretty good engines!!
That's why my bmw is dope. The inline 6 is the best motor I've had in a sedan
Check tha channel out bro I love those things , m52 m50 m54 n52 tha goat
Ive always loved the inline 6, ever since i learned what kind of insane power people get out of the skyline gtr L6 engines ive wanted to build a car with an inline 6
In my past job , we rebuilt a Scania 113 engine on 3 different occasions without removing the block. It was so simple and in 24hs the trucks where out.
So yeah , really nice to work on .
Online 4 is great too, still easy to pull an engine and make sure you do it correctly aka sending out to be bored over and honed.
They have really bad balance though which introduces a large amount of drivetrain stress. There's a reason I4s are mostly used in smaIl passenger vehicles and motorcycles.
Never thought about it but it is so very true
holy crap that’s a massive enginr
I love working on inline 6 engines so much more then any V8; my L28 in my 280z is so easy to work on compared to the El Camino I was daily driving
Scania with the V12
"I got 2 of dem I6es!"
I wish that fit in my 2021 Golf. I'll just stick to my 1.4L... T 😬👍
Personal truck ill always have a power stroke, they’re more fun IMO and about the same reliability as a Cummins in my experience, however if I’m gonna have a dedicated tow pig it’s gonna have to be a DT360/466 or a Cummins, it’s better that way because like you said, when something breaks it’s easy to get to
Love my inline 6 Barras, balance.
Love the 500 Detroit
A good engine builder rotates the crankshaft after installing a piston.
We still pull the ISC and X15 Cummins motors out along with the transmission in our kenworth trucks just so we can inspect the area that the motor mounts to for rust damage
I wish they put it in more cars
i love the I6
That's why barra on top
Yep! You can literally pull a bad sleeve and replace it, check everything with a machine level and have it back together Monday morning!
You do have more block twist and crank flex when running high horse power due to them being longer which is why top fuel cars use v8 motors
What I was going to say was by in large covered in the video here. With the only downside to the in-line configuration is physical size for length and height. But even that isn't that much of a issue if comparing these to the V blocks found in Europe. Even the 'small' v6 there is nearly as large as the I6 here and is certainly wider.
What I miss having, is the I6 as an engine option for pickup trucks and some sedans. Well save for BMW, they still rock a I6. Nissan makes a nice one, in gas and diesel but doesn't offer it for the north American market, at least one that isn't a joint venture. Toyota is the same, Isuzu paired with Nissan and is badged as 'Duramax'.
Oh boy the Bore is huge like I feel like my son can fall in lol love engines
I love how an online design is both the oldest and best engine design out there
Inline 6 is the go to standard engine of "any" size. Simple , inherently balanced and ruggedly tough is the main selling point of this design. AND scaling it to any size still gives you the same benefit as others on the family.
For an even more compact and powerful AF, you have the V 12. The same principle as the inline 6. Each bank is balanced like an inline 6 but sharing a common crankshaft and crank pin.
Now I understand why it is so strong with high and low gear, with turbo.
inherent balance of inline 6 saves a lot of time effort and money, while still producing great power
The gas variant can have 2 or 3 cylinders lose piston rings, get one home and still idle relatively smooth.
Funnily enough the first big rig i ever saw had a v12 in it.
I still love my 3408 Cats.
I just learned something wow😂
Great video
I work on Detroit’s at work and they definitely are a bit easier to work on inside the engine bay
Depends on the vehicle. But on average it is true
As a bmw guy I love tf outta a I6
The Mopar 225 Slant 6 and Ford 300 straight 6 or two of the best I6 engines ever built. Both million mile capable.
V8 macks are pretty cool
Only downside to i6 I can think of is the heat displacement into the manifold causing cylinder 1 or 6 to overheat, potentially causing broken rings,cracked heads, etc. Not saying you can't overcome this with a better designed header, but some i6 engines have this problem. Seen it in common rail cummins and bmw engines
I6 perfect* balance baby!!!
Ford 300, Cummins 5.9 6.7, and now the Duramax 3000! 💪
I got an odd engine. Good ol I5
It’s American made too.
Chevy Colorado, GMC Canyon, and Hummer H3 came with a I5 engine option. I have a canyon, and love it. It’s odd enough to stand out, but some of those H engines or overly massive.
I got i5 too though its swedish made 🕷️Sound that i5 produce are pretty nice.
@@jaskajokunen3716 to my knowledge Volvo is the only other MFR that produced a i5 with any success.
