VR6 Engine - Explained

[@jowflow2]

I thought it was like a regular V6. Had a friend that had a Jetta VR6 lot of power and loved the unique sound

[@mcahill135]

I am the first owner of a 2003 VW Jetta GLI with the 200hp VR-6 engine. It was my daily driver for 15 years. The engine is just iron clad. Coupled with a manual 6 speed it is extremely reliable and pretty efficient. I cannot seem to let it go, it’s now a good little weekend warrior. 242,000 miles and still going. Keep on Buggin’!

@flinchey That's because OBD1 vr's can sound more aggressive and have a more bass tone than OBD2's and he clearly said he's one is a 98'

[@flinchey]

Karabo Ntswane I don't understand what you're saying. by OBD1 you mean 12 valve, rather than the 24 valve ones?

[@KaraboK9Ntswane]

flinchey Nah, I'm also not too tbh sure but basically OBD is the way diagnostics were made and with OBD2 VR's because of the added 'safety' stuff like O2 sensors being different to OBD1s. But here's a link to give you an idea of how a OBD1 VR sounds like: facebook.com/video.php?v=10153553937458504&set=o.208384122530062&type=3

[@ericbeltrami2718]

Engineers that designed this engine at Volkswagen are absolutely brilliant, it's actually a real piece of art when you get down to the engineering details of the vr6.

[@NiteGambler]

And when you put 2 together you get a W12

[@7spower998]

Actually the VR6 took the engine design from a '63 Lancia V4. However, the late genius DR. Piëch based the VW engine design of an IL-6 cylinder and called it VR6 - Verkürzt Reihen - Shortened Inline6. From there a VR6 - 1 cyl = VR5, then a VR6 - 2 cyl = VR4 x 2 = W8, then a VR6 x 2 = W12, and finally a W8 x 2 = W16

[@travislangendoen975]

[@StoriesWithAlex]

VR6 isn't "V" R 6 it means Verkurzt Reihenmotor 6 Which translates into shortened straight 6

[@dildoshwaggins1017]

Alexander Hernandez nein

[@j.m.5995]

Or maybe it means straightened V6

[@Oystein87]

But still it is a combo of a V and a straight engine... So the VR6 name actually has a double meaning.

[@TheDavo6233]

In Slovak it’s “Vidlicovo Radový” which means combo of both V and R :D

[@7spower998]

That's correct. Unfortunately neither Jason nor Charles knew about it.

[@batbawls]

[@AudiophileTubes]

My 2003 GTI VR6 (24v engine) has been totally reliable for almost 16 years now! Not one issue! Initially, when I bought the car, they recalled it for a coilpack issue, but they installed new and improved ones, and i've not had anything else come up all these years. This engine is the most reliable i've ever had, even more than the Japanese cars my family has owned over the decades! This engine is so smooth, with good torque. I love tooling around town in almost any gear I want. Incredible!

So cool man. I've got a VR6 VW Corrado, first bought in Newark - USA by a portuguese immigrant, then when he came back to Portugal, he brought it and several years after i had the chance to buy it. It's from 1993 and it has only 40000 miles. Nice youtube channel you've got man.

[@SpacemanXC]

I'm kind of a Honda/Ford guy. Never really messed with VW stuff. Very interesting motor. The head is basically just like any other DOHC head, except they made it massively wide to span the cylinder configuration. Looking up some parts for this motor online. A lot of the stuff isn't much more expensive than parts for my K24. I can see why a lot of guys like these.

[@jayamd3579]

a true petrol head like myself! no hate :)

[@SpacemanXC]

jamie MacKenzie Yeah man, cool is cool. Period. Why some car guys get caught up in brand loyalty is beyond me. There are so many ways to get horse power. Why not enjoy all of them?

[@dannylopez5233]

Yeah, It's really not expensive at all. It's just scary at a glance to a some people who've never wrenched on one before. I've had my VR completely apart many times for turbocharging and after for maintenance and no part's price has ever been shocking compared to anything else i've worked on.

[@marlonlyn2719]

SpaceManDawn Not only that, but the more you learn about other brands, the more you learn about yours as well. I used to have a SOHC d16y8 and dreamed of getting a GSR or an SI Swap, but learning from what I learned from my VR6 The difference between those motors is small enough that you will max out the handling of the FWD car, before the Power Output of any of those engines on boost. Most if not all of Honda's motors flow incredibly well due to an incredible head design such that coveting an engine that has .2 liters of displacement isn't really worth it. With that being said, the K-Series engines are beast... Mechanical marvels..

[@marlonlyn2719]

SpaceManDawn The cool thing about these motors are they're like the LS Big blocks of VW. They're main design was not to maximize the amount of Power per liter, but rather maximize the amount of power in a given amount of space in an engine bay. The only issue with them (Especially with the earlier versions of the VR6) is head flow is terrible.

[@seagrass7125]

Just got my first VR6, pined after them since they showed up in the Corrado after the G60. Cool engine after all these years that has a unique sound and power delivery.

[@paulhendricken]

Great video. Thanks. I drive a 1966 Lancia Fulvia 1,216cc narrow V4 ( about 12 degrees ). Lancia may have pioneered the narrow V.

[@naota3k]

Oh man, as soon as the Humble Mechanic started going at it with the engine-talk I could tell how much he loved explaining it. I get that way when I'm talking about my computer, haha. I really learn a lot from these videos, thanks!

[@jasongooden917]

Is it a V engine or an in-line engine? Germany: yes

[@BigJohnno66]

Interesting video. The slightly uneven firing from the mis-alignment makes for an interesting exhaust sound. Lancia pioneered the low angle V configuration in a 4 cylinder engine in the 1920s.

[@scdevon]

If there's one thing VW does well, it's engine castings. That VR6 block is beautiful.

[@ChrisMonopoli]

+scdevon VW does a lot of things well the Germans build good cars you can't argue that VW, Porsche, Audi, & BMW all well built machines

[@wrenchist]

+Chris Monopoli germans know EXACTLY how to build mechanical things. hence why THE most durable vehicle ever made was crafted by their hands. but it has the most basic electrical system i have ever seen. BUT ask a german to build electrical systems, and you are GOING TO HAVE A BAD TIME.

[@comeinhandynow]

Well....I could argue as the most unreliable car according to reliabilityindex.com is the BMW m5 and the bottom 10 car list is stuffed full of German cars! Merc, Audi, BMW Check it out quite surprising.

[@santinoalvarado963]

I love the VR6. it is one of the sweetest sounding engines around, and the power and torque are amazing especially considering the relatively small displacement for a 6 cylinder engine.

[@TheAdatto]

The mx6 has a small v6

[@derekgardin1512]

​@Christian Helmsworth yep that takes the cake for small V6. 1.8L. I remember arguing with a friend years ago who insisted it was the same 2.5L duratec V6 like the MX6 Mystere had. I told him, no, its not. Its got its own V6 and is only a tiny 1.8L. They sounded so good (so did the 2.5 but the 1.8 was cool) they were not very fast but I really liked them and the sound was enough for me. A purple one came in trade to the dealer i worked at and i drove that to the licencing office for a few days lol

[@bryandoherty9399]

So the W8, W12, W16 are basically two VRs on the same crank shaft. The W8 for example it would be two VR4s on the same crank. There was someone down my street had a Passat W8, I drove it when it was for sale. I didn't have enough money for it, but it was a really nice car. It preformed well

[@HumbleMechanic]

AWESOME car to drive, but horribly expensive to fix. The engine has to come out for a lot of repairs.

[@bryandoherty9399]

HumbleMechanic it was so cool to drive it sounded awesome. I guess that's the reason why they never sold many W8 Passat models. I wish they still used the VR6. Do you know why they stopped using it? Did the 2.0T replace the VR6? I know that is used in a lot of VW products now

[@HumbleMechanic]

Bryan Doherty For the longest time, I wanted a W8 wagon. Heck even with free labor, i would struggle to afford the parts. You can buy them dirt cheap now, I just don't think I would get mixed up in one. They still use the VR6 in the Touareg. You are correct that the 2.0T TSI did replace the VR6. They are moving more towards simplifying the car line. More cars will share more parts than ever before. Part of that is using MQB. That is where different parts of the car(think from the center of the front wheels to the steering wheel) are the same on every car. It allows them to save money, and build cars that share more parts. This should make the brand better from a reliability standpoint. I worry that it may become more generic looking and feeling. They are doing awesome things with the new 1.8t and the 2.0t. The are different variants of the EA888 series engine. The new GTI 2.0t is AWESOME. Well almost everything about the new GTI is awesome. I can't wait until the performance pack hits later this year. I think the MK7 Golf R will hit mid 2015. And if a boy can dream, the Golf R Sportwagon.

[@bryandoherty9399]

I wanted one for a long time too, but I'm not mechanic, I understand how most everything works but not enough to do major maintenance myself. I never knew the Touareg ever used the VR6. That's what I thought. It seems to be a really good engine, so does the 1.8T. You would know more being a VW mechanic, but I've never heard anything bad about the 1.8T or 2.0T. I really hope it doesn't make all VW group products feel the same. The MK7 GTI is really nice, I've seen quiet a few on the roads where I live, really good looking car. I really want the Golf R Sportswagon, it looks really nice. I've heard it will have 296hp

[@veeerzes]

HumbleMechanic As an owner of a Golf MK6 R, I can say that I would MUCH rather have the VR6 R32 or R36 engine instead of the 2.0 TSI. Yes the TSI is more economical and produces more power than a stock vr6 engine, but the sound of a vr6 engine is just incredible. Also when turbocharging a vr6, they will make 400+ hp easily.

Good job Jason and Charles. I'm a Chrysler tech, and was interested in the VR6 after seeing a block in an unrelated vid. You guys make a good team. To bad you missed the mistake with the drawing of the valve train. I like the fact that the engine is a single over head cam with 2 cams in a single head. Going to look for more VR6 vids, starting at with the HumbleMechanic channel. Thanks

[@madranchtrucker6955]

I noticed the Humble mechanic mentioned a coil pack providing power to the spark plugs. I have a general idea on how they work but having you explain it would make it so much clearer. I'm also curios about how a front wheel drive works. I own an 02 impala with the 3.8L v6 and it never ceases to amaze how all that motor and transmission is crammed under the hood. Love your videos and your very simple and informative way of explaining how it all works

Your video are great; you really know what you are talking about. I have one complaint/suggestion.......get a mic. Your audio quality is fair to poor and makes it more difficult to appreciate what you are saying. You don't want your audience to work at hearing you. Talking louder helps, but that does not improve the quality of the sound.

[@joshuahall1466]

I'm not sure if this has been said, or if it was mentioned in the video and I missed it. But I believe your drawing only refers to the 24v setup. For a 12v each cam does both Intake and exhaust. There isn't one cam solely for intake and one cam solely for exhaust. Each cam has 2 lobes per cylinder; one for intake, one for exhaust. The 24v is exactly as you showed, each cam has one sole purpose, Intake or exhaust. The Humble mechanic did a great job of displaying that with the 12 valve head.

This young man is very knowledgeable and makes easy to follow presentations.

[@dion1970dion]

Interesting video, but you could have credited Lancia for this engine concept. Lancia patented the narrow angle V-engine already in 1915. In 1922 Lancia introduced the model "Lambda" with a V4 engine and the model "Trikappa" with V8 engine, all narrow angles. The successful Lancia Fulvia had a V4 narrow angle until the end of production which was mid seventies. "Der V-Motor mit engem Zylinderwinkel wurde von dem italienischen Unternehmen Lancia & C. entwickelt, weshalb die Bauart als „Lancia-Prinzip“ bezeichnet wurde. Grundlage dafür war ein Patent von Lancia & C. vom 1. Juli 1915"

[@veeerzes]

The difference in intake running length is actually compensated in the intake manifold. However, the VR6 engine was originally designed to be a turbocharged engine. This is also the reason why this engine can be turbo-ed so easily. 400+ HP with stock internals (lowered compression) is not a problem. I have a few videos on my channel from my old VR6 Turbo which made over 400 hp without any major mods to the engine itself

The cams drawing on the white board is wrong, each cam does both intake and exhaust for their respective cylinder row.

Question is, what is wall thickness where the top of piston (and rings, to a degree.) is located from the point of max acceleration to BDC. The wall thickness at the bottom of the cylinder is not as important as it is obviously only housing the piston and not containing the cylinder pressures created during combustion. Another consideration I guess is the wear characteristics of the thrust side and what inherent scope there is for rectification of cylinder ovaling by increasing bore diameter and fitting oversized pistons.

Intake and exhaust issues are dealt with via runner volume. They do overheat and warping is the last thing you'll worry about as the heads crack when overheated. And although you may not get the external symptoms you'll get small cracks intersecting the spark plug holes allowing coolant to seep in causing premature plug wear and slight coolant loss.

@WolfoxBenny. Very beautyfull engine indeed. Runs smoothly when well adjusted. Thought it was 12 or 14 degrees and very shortly build. And lots of aluminum. The engineers had to built it as light as possible because of its location in front of the front axle. These cars are still popular in classic ralleys because of the low weight and ridgid coach.

I had a total of 3 Lancia Fulvias with the narrow V4 back in the 80's. Wish I still had them now. The Lancia narrow V4 goes way back before the Fulvia though. It goes back to 1922 in the Lancia Lambda, so nearly 100 years ago. Just saying.

[@geoffwaldron5929]

First experience of this type was a Lancia 1.3 in a Fulvia. 1963 and '64 models, had the modernised; up to the minute; next gen. 11 deg V.

[@xXYannuschXx]

VW should have equipped the Golf V R32 with a supercharger, just imagine how fast that thing would have been with 350-400hp! I mean, they even put that engine into the Audi TT, that thing may be the most brutal sounding VAG engine ever made, but compared to the 265hp 2.0l TFSI equipped cars it was WAY too slow...

[@tylerhasacamera]

I've Been working on my 87 gti vr6 for a while now and this video was very helpful.

[@bircov]

Mistake at 8:38 - Lamborghini has V12. They are still using their own design, although the company is owned by Audi.

[@charleem3992]

bircov owned by vw. 😉

[@67bonanza]

The first time I worked on one of these I thought what a great concept, compact, powerful, etc.....why didn't the big 3 ever build them.....thanks for the top notch video

[@johninosare5596]

You said that 1 camshaft will open all intake valves for all cylinders while the other will open all exhaust valves. But, in the humble mechanic video, the camshaft at the right(or left) opens both intake and exhaust valves for where it is positioned and so does the camshaft on the opposite side... I was wondering if what you explained is for the 24 valve VR6 while humble mechanic showed the 12 valve VR6?

[@markrchisholm]

+John Ino Sare +fitty77 I was just about to ask the same question. Same goes for the W16 video. I just see how one camshaft for inlet and one for outlet would work without adding unnecessary complicity.

[@reginamanluyang8475]

John Ino Sare 1 camshaft open both intake and exhaust valve?!

[@547steven547]

That was a great video. The mash up of the white board and actually seeing the engine was great. Hope to see more like this, very educational. Thank you to the two of you!

[@HumbleMechanic]

Glad you liked it. It was a blast.

[@sampati4864]

40 years ago Lancia made a Vi4 which I think it operated the same.

[@JeroenWennink]

As I would say. Invention from Lancia. Just as combination of compressor with turbo. And also TDI is a invention from Fiat also as common rail. So not a invention of VW

[@Mauro-82]

Lancia patented narrow v engine in 1915 and used it from 1922 with Lambda (narrow v4) and Trikappa (narrow v8)

[@allansoares2825]

Man, your channel is very good, here in Brazil I see it almost every day!

[@damianhonegger9731]

actually VW didn't invent the VR-engine... Lancia invented this engine layout already in 1921... Lancia Lambda used a VR-4

[@SONSTHREESIXTY]

Really

[@uspitinnim9301]

I have Wolksvage Passat Exclusiv 2.8 VR6, year 1994, Automatic AC, Electric SunRoof and in mint condition. I am very satisfied with it.

[@duranamo4297]

This engine sounds amazing in my Touareg.

[@HumbleMechanic]

Angry Whale a Touareg with a proper exhaust does sound amazing!

[@duranamo4297]

Even with the stock system, sounds great. I plan to chip the computer so it redlines at a higher RPM, because the internals are rated to 7500 RPM. Also sounds good with the air filter off too!

[@jacobhendrickson8935]

I did not know this. I wonder how the power of that extra rpm is. Or if it goes flat???

[@duranamo4297]

I belive power increases but torque drops off.

[@halo3pownage]

Angry Whale if torque drops HP drops as well. You need torque to calculate HP so if torque drops, peak HP will also drop.

[@like-icecream]

I remember back in the day everyone was saying the vr6 was too heavy and everyone was doing 1.8 turbo transplants, sounds nice tho.

[@matthewheffernan3877]

Your cam layout drawing does not match the actual engine. Each cam does intake and exhaust on each cylinder bank. Valves do not cross over as you show.

[@B1GDaddyFatStax]

I caught that too. I was wondering if anyone else noticed. Guess I'm not the only one.

[@danisim9]

4 or 2 valves/cyl ?

[@OsellaSquadraCorse]

danisim9 is totally right - the drawings are for the 24v engine; the head shown is the older 12v engine.

[@matthewheffernan3877]

i don't know these engines just commenting on presentation.

[@Flowxing]

His drawings are for the newer 3.2 and 3.6L VR6 engines. The older 2.8 ABF and bored up 2.9 ABV engines with 12 valves use a "Dual SOHC" setup which obviously have a different cam layout.

[@nicodetoffol6945]

The first narrow V production engine made wasn't VW but Lancia in early sixties produced in over 350000 units and used on Lancia Fulvia It was a 4 cylinders from 1200cc to 1600cc dohc, the V adopted was from around 11 to about 13 degrees

[@rimmersbryggeri]

The Inline V is not a new concept. Lancia did the same thing on their overhead cam v4 in the 60's

[@7spower998]

That's true, and that's where the two similarities end.

[@nathanielfarinas6601]

This video makes me want to rebuild my vr6! and that clip at the end! Amazing sound and I'm glad i get to hear it every day! If it wasn't my daily I'd already have the chains changed especially since shops want to charge $1000 dollars! I'm glad you also, put Humble Mechanic in the video, now I have something else to watch!

[@hondatrix]

Correction, NO Lamborghini uses a W12.

[@ayn30]

yup literally it 2 of vr6 combined. So technically Lamborghini uses vr6 engine. 2 of them

[@KokaneKhan]

This is the best channel on KZbin.

[@Stuka87]

As I recall, the VR-6 does NOT work like an inline six. With an inline six, each cylinder has its own crank journal. With the VR-6, each crank shaft journal has two cylinders attached to it. So saying its "just like an i6" is not really correct.

[@EngineeringExplained]

The firing order and interval are "just like an I6."

[@MarkusReese]

+Stuka87 Except the VR6 has seven main bearings because in fact each one does have it's own crank shaft journal. To add onto the tech, the 24v isn't new. They also were 2.8L with exception of the R32.. That changed for the 02 model with the 01 being last year of the 12v. I in fact have a 24v block from factory but a 12v head. Of note that the 99-01 12v had different lift/duration between the two banks of cylinders to account for the different runner lengths.

[@EinachserLS]

+Stuka87 If that were true a VR6 would be running almost like a 3.2 litre 3 cylinder. An engine more suited for a farm tractor really.

[@MarkusReese]

EinachserLS What he describes was not uncommon where two rods are on the same journal. Just look up the smallblock. Most V6s for balancing purposes are not a true shared journal but do have an offset with two pistons between each main. I am thinking that is what stuka thought. The VR6 does alternate rod/main.

[@Egolman55]

+Stuka87 He did say "more in common" at around 0:41.

[@chevychuckles3156]

I never knew how 'odd' the VR6 is. I always thought it was just a V6 with a sub 90 degree V configuration. Nice video.

[@plant4143]

+ChevyChuckles Almost all V6s that are not V8s with 2 of the cylinders chopped off are below 90 degrees.

[@Sethemiah]

what about a W engine? i drove an isuzu w-12 something or other, cab over, it was fun, but i never quite figured it out.

[@EngineeringExplained]

Check out my video "W16 engine" :)

[@bradymoritz]

I had thought the bores were perpendicular to each other instead of slanted, this makes more sense now that I see they are slant bored. Thanks for the vid

[@efreitorhabibulin238]

15:20 that VR6 sound puts V8's to shame :P

[@anonymousfox345]

false lol

[@MrKeef23]

Efreitor Habibulin lmfao no way

[@231mac]

Efreitor Habibulin HAHAHAHAHAHAHAHAHA!!!! You're silly...

[@lights0ut503]

No engine sound in the world puts a v8 to shame v8 is the #1 engine sound facts only you can't say nothing on that

[@c4marco]

So this is the first time i saw a video of you and i think it's awesome! I am a mechanical engineering stundent from Austria and i can learn somthing with your videos. Thank you!
