The first engine I built with my dad was an inline 6 so it has a soft spot in my heart. Such a wonderful piece of machinery! I'm glad it is making a comeback!
Never rebuilt one. The chassis failed 1st. My current I-6 has 200,000 on it. The frame is almost to the point of scrapping it. But I live in the rust belt. The 58 Chevy pickup I worked on. The valve cover was a good place to put coffee cup while I was tuning the carburetor.
Eh...I-6s can be heavy pigs, too. Old 4.0L I-6s from Jeeps were in the 450lb range...then they changed to 3.7L V-6s that weighed 425lbs...then they changed to the 3.6L Pentastar V-6s that weighed 330lbs. Output went from 190hp/235lb-ft to 210hp/235lb-ft to 290hp/260lb-ft. It's all in the technology, layout, and casting processes. Obviously, this is just one example, and Jeeps are special birds as compared to classic M-3s...but an Inline-6 isn't light just because it's an Inline-6.
Australian 4.0l Turbo straight six in the Falcon XR6T or F6 Typhoon. Know as the Barra six is one of the best ever straight six engine ever made in the world, it performance is making most other six cylinder engines including skyline engines a joke.
From an engineering standpoint, I think the "balance" part of inline 6's are misunderstood. As he said, the forces balance each other out. This is mainly important for bearing life. This was much more important in the early days of cars but now, we've figured out how to balance forces in almost any engine configuration and also how to make better bearings. The inline 6 configuration does still make balancing a lot simpler. There's no need for balance shafts or counterweights which makes them much less complicated and lighter. Because if this, you can squeeze a few more horses out of an inline 6 because there's less mass to rotate. This also makes them lighter along with the fact that the block design requires less material and you only need one head. So from a driving standpoint, you aren't going to notice much of a difference between a v6 or an i6. The i6 may seem to rev a little easier due to the lessened oscillating masses but that's about it. The smoothness from an engine is only dependant on number of cylinders and firing order and not really the configuration.
Two reasons. That is why most OTR tractors are inline six. Just last longer. But the EPA, AQMD and CARB have been working on that. (The last longer part) CAT is longer authorized to make 1 million mile, over the road diesels anymore. When you consider how long it takes for a tractor trailer to travel 1 million miles. It is way shorter than the payments . So if it can't make CAT standards. CAT won't make it. OR rebuild it 3 times before you finish paying for it. Most non-commercial vehicles get replaced because the engine or transmission pukes. And /or they are out of style. IC engines are out of style.
@@warrenpuckett4203 IC engines might be out of style but until someone gets apartments and condos to put in chargers, and a lot of other people start digging up enough metals to build batteries to power every car, we are stuck with IC.
For starters, W12s aren't as smooth as a V12. A W12 is essentially two VR6 engines "fighting" at the crankshaft. The sound difference between them is also different as well and the W12 has a more harsher sound. The V12 on the other hand, has a silky smooth sound. A car for example, a 2004 Volkswagen Phaeton can have a W12 as an option. The car launched with the torqy W12 but working on it is a pain in the ass. One of the o2 sensor is so close to the engine that it can melt when you mash the accelerator a lot. So, I like the phaeton but it's too much maintenance for the W12 version.
The BMW 3l I6 in my 530 is the best Engine I have ever had. Smooth rides, no problems whatsoever, great mileage for a 2 ton vehicle and powerful enough for my everyday car. It’s not high performance car (touring), it’s not the most heroic sound you ever heard but for a standard everyday car it’s the best engine I can imagine.
It is tho because most V engines that stands out in V Community will mostly V8s V10s And V12s a V6 is like that one weirdo kid tryin to act cool also nobody in the V community likes V6 engine...
They are. The 5.9 Cummins is the best pickup engine in my opinion. They have more torque due to the longer stroke, and they’re a lot easier to work on compared to the Duramax and Powerstroke. Also basically all heavy duty trucks (semis, dump trucks, etc) use straight 6 engines.
Bmw owner here, inline 6 are the bomb, the have a beautiful sound are easy to work on, and one of the most important, you have a cold side and a hot side in your engine bay
The jeep 4.0 was one of the best L6 ever built. Anyone who says there is some inherent weakness in the design of an inline 6 can be shut up real quick, just show them the nearest XJ with 400,000 miles on it running like new, and say "what inherent weakness"? 😄
Inline six is the most reliable engine configuration by a mile... Almost all million mile cars you see are inline sixes and for good reasons: balance, simplicity, power delivery etc And the reason mercedes is going back to inline six is they want their old glory of making reliable machinery and I'm pretty sure they will succeed
Wrong. Straight four is. Even with vibration or extra balance shafts.. it has a far more simple crank and far fewer moving parts. Even a V8 has a simpler crank.. cross plane only has four throws and flat plane is also four throws and almost identical to a four cylinder. Far more durable. VEE engines are more rigid. They don’t suffer from bending or torsional loads as much. And then there’s the packaging. A straight six is an absolute PITA to install in a vehicle and get the same interior to exterior volume ratios.
Mercedes Benz and Jaguar are replacing all their v6's with straight 6 for superior smoothness, packaging and lower cost of manufacture. The straight 6 is thriving!
Mopar Magic What's a slant-6? Never heard of before. Radials are just old air cooled aircraft engines and that won't be well suited for cars. W6 with 2 VR3 cylinder heads are just a more complicated V6 that cost more. And a 6-rotor wankel just won't happen outside of some wankelfanatics garage But the flat six would have been nice though! Would be cool if Porsche had it over its whole lineup and not just in the 911/718/Boxster/Cayman. And yes, I am fun at parties..😛
Oscar Merlin Slant-6 is an inline 6 at an angle. Slang for an old Chrysler engine. I was just being silly. If you know of any more 6 cylinder/rotor monstrosities throw them out there! lol
there is no W6 or W8... only W12 and W16 and you cant really fit 6 wankel, as far as I know, that would be pretty hard to pack into car, but it would definitely be fun to see how much power you could get from so many rotors :D
One of the inline 6 advantages that is a 2 in one: most inline 6 engines have 7 main bearings because no two rods share a journal, this means it has a much longer life span and the longer crankshaft has more rotating weight that translates to more torque than a traditional v6.
@@raus_mit_Islam sequential turbocharging in a twin turbo setup drastically reduces lag by using one turbo for lower engine speeds and another for higher speeds. Inline 6 engines can easily accommodate sequential turbos because, since all cylinders are accommodated in a straight line, you can basically mount one turbo in front of the other and basically set both on either side of the engine. A V6 engine makes it more difficult because even if it’s not as long as an I6 engine, it’s wider and thus leaves less space to the sides of the engine.
Can you fucking read you illiterate dipshit? Most 18 wheelers have inline 6 engines because they are more reliable and have more torque. Since 18 wheelers are constantly on the road and hauling shit, they need durable torquey engines. Inline 6 engines usually have more torque than v6s.
Most of the engines known for extreme durability, reliability, and longevity have been in-line sixes. From Ford, AMC/Jeep, Nissan and Toyota, to Cummins and most any other commercial-use Diesel out there, just to name a few.
inline 6 engines have more main bearings on the crank than even a v8. inline 6 engines have 7 main bearings compared to 5 on a V8 and only 4 on a V6 so yes the bottom end lasts longer because each bearing has less stress. 7 bearings with only 6 cylinders have a lot less stress than 4 bearings with 6 cylinders. that's why all 18 wheelers here in the US use inline 6 engines.
Inline engines produce more torque, most heavy industrial engines are inline, trucks, ships, locomotives etc.Cars a very light you can probably get the same torque out of either.
Brian Rocha "18 wheelers" as you call them use Diesel engines, which can be almost any displacement with almost any number of cylinders. Most of the diesels installed in road vehicles are I6 or V8 though. However they are nothing like the gasoline powered I6 engines. Diesel engines usually have a large displacement compared to the number of cylinders and they run at very low RPM compared to gas engines. So while you might be partially correct that a lot of commercial vehicles use I6 engines, that has nothing to do with this video at all. This video wasn't about Diesel engines.
forgot to mention that inline 6 engines don't have ignition pulses on the same main bearings twice in a row. ever. because conrods aren't paired on the crank. leads to them lasting a LOT longer... particular when paired with modern metallurgy.
If you're talking about a Chrysler slant 6... not likely. Our family had a camperised 1977 Dodge Tradesman van. At 50,000 miles it was burning oil and had such low compression you could not park the vehicle on a hill without wheel chocks.
Nothing beats the Busso designed Alfa V6. It's based on an inline 6 configuration and uses the inline 6 firing order but takes advantage of the V6 positives making it such a sweet engine. Nothing beats it.
My car has a I6 it's a 2009 BMW and I absolutely love it, I talked to an experienced BMW mechanic about the engine and he said it was the rock solid long lasting engine that they still produce because of its lifespan, minimal cost and reliability and that it was the way to go for sure
oh yeah, even old e34 l6 cars with 200,000 plus miles are considered acceptable because of the engines reliability and long lasting nature. Love my 1999 BMW 528i as well as my (and I know this is a bit of an odd ball, but) 2008 Peugeot 607 V6
Jamie french if u do the maintenance yourself which isnt that hard than yea it way cheaper, all these mechanic industries have a thing for euro cars and for some reason make their maintenance more expensive
Aesthetics & CarsTM I do my own work to my e46, it's the 325xi and just hit 100,000 miles. Saved myself $2000 or more just doing all the maintenance myself.

Right now she's running flawlessly

Also Ford Xr6 turbo the 4.0 L inline 6 turbo sedan produced from 2002 to 2016 made 270kw stock and the XR6 sprint made over 370 kw and 650nm on overboost.
I've got a 1993 benz with the m104 straight 6 and it's amazing. I drive hard everyday thru the canyons at lake billy chinook and couldn't be happier. After 3 long hard years (well maintained as far as fluids etc) and a total of 240xxx miles ive never had to fix anything other than a neutral safety switch and AICV. I wish they got more appreciation. Truly amazing motors. Straight 6 for life 💯💯💯
Give me a straight six anytime. Not only do they sound better, but I believe they make better torque naturally aspirated (for the same capacity) than any other engine configuration (including V8).
Not true. Maybe usually in practice, but the configuration itself is irrelevant. I6 vs. V6, with all other things kept equal (bore, stroke, ignition and valve timing/lift, state of tune, compression, etc), will produce equal torque. Comparisons that come to mind include the Toyota 2JZ-GE (3.0L I6) vs. 1MZ-FE (3.0L V6). They both made about 215 lb ft of torque. And the Ford 4.9L I6 made _less_ torque than Ford's own 4.9L V8 in most years. (But it made better *low-end* torque, since it was designed as a truck engine).
@@nthgth People see and hear what they want to hear. Maybe someone heard a inline with a performance exhaust one time and now he thinks they all sound better than the v's...... Lol damnit
@@filmandfirearms yeah but exactly, inline vs. Vee is as relevant as one V engine vs. another V. Everything depends on the intended purpose, not on the cylinder configuration.
I'm not a mechanic and barely understand how an IC engine works but from the vehicles I've owned over the last 35 years, the inline engines always seemed to last longer than the V6's or 8's. And the best of those inline engines was the Slant-6. I had three and put over 300,000 on all of them, the bodies they were in rusted through before they wore out
OK, there is some misinformation here. V6 engines with balance shafts are incredibly rare; typically they *only* have a harmonic balancer driven by the serpentine belt (much less force required to drive it) and engine/transaxle mounts.
It comes down to how the bore vs stroke is proportioned. Also how the cam profiles look, and intake runner length, exhaust design and so on... But often, car companies "build accordning to the prejudice", so they would build the engine to conform to the buyers prejudice.
Car companies build according to what will make them the most money using the least amount of money to do so. They are stockholder companies that are required to act in the shareholders best interests. They aren't going to design a motor around consumer ignorance. Now the marketing department may play to consumers being stupid (this car has stripes and useless decals so it's worth an extra $10k!!), but the R & D department is not going to purposely design a shitty motor for any reason. The average consumer doesn't care or even know the difference between a V6 and an I6 anyway. Given that, I don't see how there could even be any discernible prejudice between the two for the majority of their customers. Gearheads only make up a small percent of the car buying public.
Inline sixes ARE NOT dead and are nowhere near being dead. They may not be used in cars anymore but they are still commonly used in road tractors. They are capable of creating high amounts of torque at a low rpm which is good for hauling big loads.
The V design in itself is not smooth. It requires a lot of counterbalancing. Ford's big 300 six in it's trucks were absolutely bullet proof, and they would run forever!

@@sergiohannover No, it's a Ferrari Derived engine. They spent an additional 120 million dollars to further refine the F154 engine. So we can agree that V6 engines can be engineered to be quite spectacular.
Should at least had the H6 in the presentation too. Sound wise the inline-6 and H6 sounds a lot better than any V6 or V8. Also realize that Volvo were successful in mounting a transversal inline-6 in their cars. And they have actually made a prototype V10 car, but it was never on the market due to "image problems".
It's called BMW N55. 3.0 Liter inline-6 with one twin-scroll turbo (twin-scroll = twin exhaust channels in the turbo) It is based on the same engine as the M235 but with reinforced components and a lighter fly-wheel (same fly-wheel as the S55 engine in the M3/M4)
He forgot the main advantage, which is why the inline is not actually on its weigh out. It is still the king of the road with medium and heavy duty trucks. The engine makes more power with better manifolds, that can be more direct. The natural balance also reduces internal drag of momentum.
A v8 is just trying to be a V12 but not good enough. A V12 is just trying to be a V16...I could go on but I think I've made my point about the silly logic behind that statement.
Bad or good engine has nothing to do with a number of cylinders. For example, there are some I4s producing more hp than 6 or 8 cylinder and with more tuning potential
@@kostamihalopoulos4534 Ford GT. The GT40 was made back in the 60s, before V6 engines were much of a thing at all, and had a 7 liter V8. Also, the new GT is faster because of the way the body is designed, not because of its engine, as it makes less power than many of those V8s it can outrun
not really. it's just a packaging think. rest of the desgin of an ls1 is pretty much rubbish. the ohv v8 is just good, due to evolution. they know how to build them, just like porsches know how to build 911's, because they alway build them. anyway, the best of bost worlds would be an boxer 6 zylinder. has even less vibration then an inline 6 and good packaing. fairly expensiv to build ...
+spootneo64 How is that a problem when overall output will still be better? You're focusing too much on the lower peak output of a typical OHV V8, not the meaty, usable torque curve that makes them so awesome. I'm sorry, but as impressive as it might seem to some people, It isn't necessary for an engine to rev to 9,000rpm and make 101hp/L when an engine can and should be tuned to make most of its muscle barely above idle and carry that throughout its rev range. The reason why so many cars have more complicated valvetrains its because they can't make power without the piss being revved out of them. Their numerous disadvantaged to that.
Interestingly in Australia the Ford 4 litre straight six has proved to be a longer lasting and better engine than the GM 3.6 V6 of the same period. Especially in "Barra" form. But even in the mundane bread and butter sedans it is a smooth powerful and long lived engine that can take abuse and many kms without complaint.

My dad's Jeep Cherokee 4.0 is great plus a good sound from the i6
andrew cadena well the v design takes up space laterally
all the way with straight 6
Roxana Santiago well you could go with a vr6 engine
Roxana Santiago feels like nobody herd of vr6
vr6 is really a questionable 6 cylinder, just because nobody really knows if it should be considered a v6 or a i6. I'd get a vr6 Volkswagen though
Straight 6 has more torque
You would think more companies would is a vr6 engine. It’s compact and has only one valve train.
Mercedes Benz and Jaguar are replacing all their v6's with straight 6 for superior smoothness, packaging and lower cost of manufacture. The straight 6 is thriving!
Radial-6 vs Flat-6 vs 6-Rotor-Wankle vs V-6 vs Straight-6 vs Slant-6 vs W-6.
Woah...
Mopar Magic What's a slant-6? Never heard of before.
Radials are just old air cooled aircraft engines and that won't be well suited for cars.
W6 with 2 VR3 cylinder heads are just a more complicated V6 that cost more.
And a 6-rotor wankel just won't happen outside of some wankelfanatics garage
But the flat six would have been nice though! Would be cool if Porsche had it over its whole lineup and not just in the 911/718/Boxster/Cayman.
And yes, I am fun at parties..😛
Too complex.
Oscar Merlin Slant-6 is an inline 6 at an angle. Slang for an old Chrysler engine. I was just being silly. If you know of any more 6 cylinder/rotor monstrosities throw them out there! lol
there is no W6 or W8... only W12 and W16 and you cant really fit 6 wankel, as far as I know, that would be pretty hard to pack into car, but it would definitely be fun to see how much power you could get from so many rotors :D
+Emir HD I got W confused with VR6. Also look up 6 Rotor Rx4 or 6 Rotor BMW M6. It's a really cool looking engine and sounds crazy!
Fine I will settle for a v48
Nah fam gotta have that V64
Trash compared to my w80
Inline 360 is king
How bout my v1 t180
What yall know about that Y369
One of the inline 6 advantages that is a 2 in one: most inline 6 engines have 7 main bearings because no two rods share a journal, this means it has a much longer life span and the longer crankshaft has more rotating weight that translates to more torque than a traditional v6.
Unlike the V-6, an inline 6 can use easily accommodate a sequential turbo charger.
Why?
@@raus_mit_Islam Bcoz V-6 need to seperate side-to-side the turbo,also that also make the engine so complex
i love v6 though... inline also. very pro engines 😎
Ehhh Nissans VQ is the toughest V6 engine out there. It can handle anything
@@raus_mit_Islam sequential turbocharging in a twin turbo setup drastically reduces lag by using one turbo for lower engine speeds and another for higher speeds. Inline 6 engines can easily accommodate sequential turbos because, since all cylinders are accommodated in a straight line, you can basically mount one turbo in front of the other and basically set both on either side of the engine. A V6 engine makes it more difficult because even if it’s not as long as an I6 engine, it’s wider and thus leaves less space to the sides of the engine.

Inline 6 is just more reliable. R32 solved packing quite easily. set it back and run a transfer case to both front and back wheels.
heavy machinery themselves use an inline setup since it is more reliable. its pretty rare we see a V configuration
LMFAO GTFO just say you like inline 6 more don't make some shit up
18 wheelers/lorries use inline engines because they are more reliable and have more torque.
Can you fucking read you illiterate dipshit? Most 18 wheelers have inline 6 engines because they are more reliable and have more torque. Since 18 wheelers are constantly on the road and hauling shit, they need durable torquey engines. Inline 6 engines usually have more torque than v6s.
billy heaton Harambe is right. Trust me, I am a Truck mechanic.
The Ford I6 in the Falcon. known as the Barra, is one of the best 6s in my opinion!
Peter G glad americans could lay the ground work for australias best i6
Most of the engines known for extreme durability, reliability, and longevity have been in-line sixes. From Ford, AMC/Jeep, Nissan and Toyota, to Cummins and most any other commercial-use Diesel out there, just to name a few.
Tom - Sit down fanboy adults are talking here.
Tom - Back at ya little tommy :)
You got to be kidding right? There is a skyline here in Australia with a barra in it and eats RBs with twice the money spent on them all day long...
Inline motors also have more torque than the V setups. That is an important fact to exclude when talking performance.

The Ferrari Derived V6 engine used in the new Alfa's would love to have a word with you. As well as the Nissan GTR and the FORD GT.
@@paulj9821 yeah i like that idea and honda had a 02 v6 with 240hp and no one is talking about it.
I've always been under the impression that I6 had more torque and durability than V6! Not sure how accurate that is.
I've heard the same thing. Inline-6's are so smooth; they are wonderful. They make a great sound too...listen to an old Jaguar sometime.
It's not lighter as it uses heavy counter weight and possibly requires a balancing shaft.
inline 6 engines have more main bearings on the crank than even a v8. inline 6 engines have 7 main bearings compared to 5 on a V8 and only 4 on a V6 so yes the bottom end lasts longer because each bearing has less stress. 7 bearings with only 6 cylinders have a lot less stress than 4 bearings with 6 cylinders. that's why all 18 wheelers here in the US use inline 6 engines.
Inline engines produce more torque, most heavy industrial engines are inline, trucks, ships, locomotives etc.Cars a very light you can probably get the same torque out of either.
Brian Rocha "18 wheelers" as you call them use Diesel engines, which can be almost any displacement with almost any number of cylinders. Most of the diesels installed in road vehicles are I6 or V8 though. However they are nothing like the gasoline powered I6 engines. Diesel engines usually have a large displacement compared to the number of cylinders and they run at very low RPM compared to gas engines. So while you might be partially correct that a lot of commercial vehicles use I6 engines, that has nothing to do with this video at all. This video wasn't about Diesel engines.
Does “inline” and “straight” mean the same thing?
yes
In terms of engines yes.
Kyle Stratman yupp
Yah
Yes
forgot to mention that inline 6 engines don't have ignition pulses on the same main bearings twice in a row. ever. because conrods aren't paired on the crank.
leads to them lasting a LOT longer... particular when paired with modern metallurgy.
This is the best comparison and contrast of the engines I've seen, and I've seen a few. Plus bonus new I6 engine coverage. Thumbs up!
Can you do a video on the advantages and disadvantages of V8 and straight 8? Just cos why not.
Diguz91 Lincoln had one in the 70s
How about OHV V8 engines vs DOHC V8 engines? I'd like to see that, but then again, they're European and likely will butcher that on up.
Straight 8 was shit because of its horrible bore and small stroke.
Or flat plane vs cross plane
Surprisingly, this quote can fit in a lot of situation.
Never said it was the correct answer though.
inline 6 > all.
I just like V6, sounds better to me.
except V6, V8, V12....
*cough* inline 5 *cough*
The equal is a H6.
V6 and V8 engines sounds like they have a misfire.
To be fair a slant 6 engine is one of the most dependable engines ever made.
If you're talking about a Chrysler slant 6... not likely. Our family had a camperised 1977 Dodge Tradesman van. At 50,000 miles it was burning oil and had such low compression you could not park the vehicle on a hill without wheel chocks.
The inline 6 engines seems to be the most reliable engines in most domestic made cars and light trucks. Such as Ford and Chevy...
Nothing beats the Busso designed Alfa V6. It's based on an inline 6 configuration and uses the inline 6 firing order but takes advantage of the V6 positives making it such a sweet engine. Nothing beats it.
Except for any car with more than 6 cylinders? Or with more horsepower?
My car has a I6 it's a 2009 BMW and I absolutely love it, I talked to an experienced BMW mechanic about the engine and he said it was the rock solid long lasting engine that they still produce because of its lifespan, minimal cost and reliability and that it was the way to go for sure
oh yeah, even old e34 l6 cars with 200,000 plus miles are considered acceptable because of the engines reliability and long lasting nature. Love my 1999 BMW 528i as well as my (and I know this is a bit of an odd ball, but) 2008 Peugeot 607 V6

Right now she's running flawlessly
grew up with the BMW inline six, the m50, n52 and now n54 and it is my choice.
Erik Alvarez the S54 is the best for me from all the BMW i6's

Let's have a vote. V6 or Straight-Six? I'm going with Straight-Six.
Straight Six
V8
my preference is I-6 for smooth sound and feel.
inline 5
I own vehicles with both, and I prefer the I6 over the V6. I like the higher torque output of my I6 equipped vehicle.
I've got a 1993 benz with the m104 straight 6 and it's amazing. I drive hard everyday thru the canyons at lake billy chinook and couldn't be happier. After 3 long hard years (well maintained as far as fluids etc) and a total of 240xxx miles ive never had to fix anything other than a neutral safety switch and AICV. I wish they got more appreciation. Truly amazing motors. Straight 6 for life 💯💯💯

Can't see bmw ever getting away from the straight six engines.🤔
They have flat 6 and v8
Give me a straight six anytime. Not only do they sound better, but I believe they make better torque naturally aspirated (for the same capacity) than any other engine configuration (including V8).
This is true
Not true. Maybe usually in practice, but the configuration itself is irrelevant.
I6 vs. V6, with all other things kept equal (bore, stroke, ignition and valve timing/lift, state of tune, compression, etc), will produce equal torque.
Comparisons that come to mind include the Toyota 2JZ-GE (3.0L I6) vs. 1MZ-FE (3.0L V6). They both made about 215 lb ft of torque. And the Ford 4.9L I6 made _less_ torque than Ford's own 4.9L V8 in most years. (But it made better *low-end* torque, since it was designed as a truck engine).
@@nthgth You can't really compare the Ford 4.9 I6 to the 4.9 V8 as they were made for different purposes
@@nthgth People see and hear what they want to hear. Maybe someone heard a inline with a performance exhaust one time and now he thinks they all sound better than the v's...... Lol damnit
@@filmandfirearms yeah but exactly, inline vs. Vee is as relevant as one V engine vs. another V. Everything depends on the intended purpose, not on the cylinder configuration.
I'm not a mechanic and barely understand how an IC engine works but from the vehicles I've owned over the last 35 years, the inline engines always seemed to last longer than the V6's or 8's. And the best of those inline engines was the Slant-6. I had three and put over 300,000 on all of them, the bodies they were in rusted through before they wore out
The straight 6 is straight but v isn't
v6 is for gay
V for vagene.
v engines are gæ

I hope not! ^^
Michael Gallagher That's no fun.
Motors=torque=burnouts...sounds fun to me.
Michael Gallagher technically electric gets instant torque so technically you are incorrect
Austin Wolfe what you on about...
There is usually enough space for a V8 if you can fit an I6. I prefer I6 over V6, but V6 engines sound better to me.
I6 sound sooo much better! Smooth and not fluttery
OK, there is some misinformation here. V6 engines with balance shafts are incredibly rare; typically they *only* have a harmonic balancer driven by the serpentine belt (much less force required to drive it) and engine/transaxle mounts.
Don't straight 6's generally produce a little bit more torque than a v6?
soaringtractor So you say a V6 has less torque than an inline six, that is exactly what Reid Smith said but you say he is wrong?
It comes down to how the bore vs stroke is proportioned. Also how the cam profiles look, and intake runner length, exhaust design and so on... But often, car companies "build accordning to the prejudice", so they would build the engine to conform to the buyers prejudice.
Car companies build according to what will make them the most money using the least amount of money to do so. They are stockholder companies that are required to act in the shareholders best interests. They aren't going to design a motor around consumer ignorance. Now the marketing department may play to consumers being stupid (this car has stripes and useless decals so it's worth an extra $10k!!), but the R & D department is not going to purposely design a shitty motor for any reason. The average consumer doesn't care or even know the difference between a V6 and an I6 anyway. Given that, I don't see how there could even be any discernible prejudice between the two for the majority of their customers. Gearheads only make up a small percent of the car buying public.

Inline sixes ARE NOT dead and are nowhere near being dead. They may not be used in cars anymore but they are still commonly used in road tractors. They are capable of creating high amounts of torque at a low rpm which is good for hauling big loads.
The V design in itself is not smooth. It requires a lot of counterbalancing. Ford's big 300 six in it's trucks were absolutely bullet proof, and they would run forever!
@John You're through the "break-in" period!
Imagine that engine on a aluminum body. U would never need to buy another car
Bullet proof... do you mean towing my tractor over blood mounten. The old 415,000 mile 300 l6 never drops below 4,000 rpms.

The slant 6 engine has to be the best engine ever made for long life and endurance
This is no bullshit my first car was a 1975 Plymouth Valiant.
Great little car, no power but it was reliable as hell
Another engine that’s equally as reliable as the slant 6 is the Ford 240/300 inline 6.
He forgot the main advantage, which is why the inline is not actually on its weigh out. It is still the king of the road with medium and heavy duty trucks. The engine makes more power with better manifolds, that can be more direct. The natural balance also reduces internal drag of momentum.
Let’s b honest a v6 is just trying to be a v8 but not good enough
A v8 is just trying to be a V12 but not good enough.
A V12 is just trying to be a V16...I could go on but I think I've made my point about the silly logic behind that statement.
V type engine has a better sound than rough rubbish
Did you forget about the V6 Ford GT40 that is faster than most V8 engines
Bad or good engine has nothing to do with a number of cylinders. For example, there are some I4s producing more hp than 6 or 8 cylinder and with more tuning potential
@@kostamihalopoulos4534 Ford GT. The GT40 was made back in the 60s, before V6 engines were much of a thing at all, and had a 7 liter V8. Also, the new GT is faster because of the way the body is designed, not because of its engine, as it makes less power than many of those V8s it can outrun
Inline sixes are better. Smoother than any other engine, sound better and last longer than a V6.

Beginning to see why OHV V8 still competing. Just one camshaft, so less friction due to fewer parts.
Hi Rob Ford, hows hell
And because it's also cheaper, stronger, lighter, more compact and offers a lower CG.
Skipper but shitty airflow due to 2vpc... sad for an engine that displace a huge amount of air
not really. it's just a packaging think. rest of the desgin of an ls1 is pretty much rubbish. the ohv v8 is just good, due to evolution. they know how to build them, just like porsches know how to build 911's, because they alway build them. anyway, the best of bost worlds would be an boxer 6 zylinder. has even less vibration then an inline 6 and good packaing. fairly expensiv to build ...
+spootneo64 How is that a problem when overall output will still be better? You're focusing too much on the lower peak output of a typical OHV V8, not the meaty, usable torque curve that makes them so awesome. I'm sorry, but as impressive as it might seem to some people, It isn't necessary for an engine to rev to 9,000rpm and make 101hp/L when an engine can and should be tuned to make most of its muscle barely above idle and carry that throughout its rev range. The reason why so many cars have more complicated valvetrains its because they can't make power without the piss being revved out of them. Their numerous disadvantaged to that.
This was very educational.
I wish my school can teach me this!
I own 95 Ford F-150 I6 engine. It is good engine. Ideal for more torque and suit for towing.
6 in a row, built to tow
Interestingly in Australia the Ford 4 litre straight six has proved to be a longer lasting and better engine than the GM 3.6 V6 of the same period. Especially in "Barra" form. But even in the mundane bread and butter sedans it is a smooth powerful and long lived engine that can take abuse and many kms without complaint.
