VR6 and V6

[donlj]

Just a question, why everybody talk about the V6 and VR6 as the same engine... what I mean is that some people have a V6 and talked about their cars as VR6 and in a few pics is like "pics of my VR6" and it's the V6!

As a lot of you probably know, the R in the VR6 is a kind of engine not only a name for the car...

and as in Europe we don't have VR6 in the golf IV, is sometimes difficult to understand... and what is the difference between the 3 names you use: VR6 24 & V6 24v & VR6 12v ?? thanks

In America the VR6 is the 15% 6 Cylinder. This engine had 12V since the MK3's until 01' in the MK4's. starting in 02, VW put the 24V VR6(new engine) in the GTI and the GLi(Bora/Jetta). I think the V6 in the golf in europe is the VR6 that's in America. Lastly there is no 24V V6 that is produced by VWAG. At least none that I know of. There is however a 30V V6 which is in the A6, A4, and the Passat.

In europe they call the vr6 the v6. same engine..

In the U.S. the 15 degree 6 cylinder engine in the Corrado ,GTI , Jetta ,B4 Passat and Eurovan has always been knwon as the VR6 for V-rehienn(sp?) 6...meaning V inline 6, and it has a nice (loyal) following... From it's introduction it was a 12V until the 24V made it's debut in Europe... In Europe it is known as the 24V V6 or V6 4 motion as most cars are badged that way...over here, even the new 24V VR6s(same engine you guys have) carry the VR6 badge on the trunk except the GLI.

When talking to a car enthusiasts if you just mention your car has a V6 you could be refering to any number of cars, but if you mention your car has a VR6 there is no doubt you are talking about a DUB.

In europe VW call the car V6 4motion because they don't want to confuse customers. It is the badge and name of the car. But the engine is refered to as VR6 24v here too.. Period.

[siuson2]

This thread is confusing...

[Strikland]

minor point, 24v was in 2002.5, yes?

[24VGLi]

YES

[Strikland]

calm down, grasshopper. I was just making a (tiny) correction. no need to beat yourself up over it.

[24VGLi]

I just like banging my head against the wall.

correct, however, in Europe their equivilent of a 24v VR6 GTI is a Golf V6... comes with VR6 engine... here, the car is named after the motor.... there the car is named, then a motor is fitted.

[siuson2]

hmm i think i kinda understand now...

sorrie, i m slow....
but im gettin t here

[donlj]

No the V6 24v 204hp engine is not called VR6 so how can you say "Golf IV VR6" if it's not a VR6 style? the one with 174hp yes it's a VR6 but not the V6 24v which I'm talking of...
look at the difference:

VR6 (symmetric engine) and V6 (asymmetric engine)

Ahh.....@!! Some Graphics!! nice!!

[JozkoMrkvicka]

Both the 12v (174hp) and the 24v (200hp) 6-cylinder engines offered in Golfs and Jettas have the arrangement as shown on the right image....and they are both reffered to as VR6 engines in North America. As for car names, all VW cars with the VR6 engines (as correctly pointed out above) have a VR6 badge except for the GLI Jetta...now I am not sure about the VW Van badge which also has a VR6 in it... I also read somewhere that Mercedes sells a vehicle with the VW VR6 engine in it...

[donlj]

NO! everybody in Europe knows that the 174hp and 193hp of golf III, corrado and Golf IV for US only is a VR6 as the left picture!!!!! that's a VR6 engine! on the right it's the new V6 2,8l 24v 204hp....... please don't mix the VR6 with the V6 24v.

go to the link of the pictures and read the difference between the 2. We are in the best VW forum (I think it) and I don't understand how can you mix it.

I am not sure what article you are reffering to, but the article (link above) says that the image on the right is (I quote): " Right : Asymmetric design of VR6 "...

[gizmopop]

donlj the picture on the left is a conventional V6, the one on the right is the VR6, 12V and 24V.the diagram is specifically referring to the 12v in this instance, but both 12v and 24v share the V angle of 15 degrees. when viewed from above they both look like the illustration on the right.

The 12v and 24v are VR6s. Both 15 degree v6 engines. The only v6 vw uses is in the ~99' and newer passats and its a 30v. A regular v6 would not fit in a golf.

don't forget 24v is also in GLX!

[donlj]

Ok your right!! so I didn't read a good article

now everythings clear... so what is the exact difference between the 174 and 204hp of the Golf IV ? variable valve timing and? thanks

[mark4]

12 Valves

[waterpumper]

Ok I have a headache after reading this post. I have a 2003 Golf GTI VR6 That is what it said on the sticker thats what it says on my rear hatch. If you have a problem with this then contact VWofA. They are the ones who badged the cars. Not the people on the vortex.

[donlj]

I was just asking, so stay cool

12V.... good one, so VW just added 12 others and wow new engine... I'm asking more in details if possible...

They also changed the design of the way the cams/valves operate. Now one cam operates all intake valves on both banks, and one cam operates all exhaust valves on both banks. So, half the valves sort of go sideways from one bank to the next. VW did this so they could do variable valve timing (absent from 12v).

[donlj]

ok! thanks... I heard about that...

do you know when exhaust manifold will be available for the 24v??? thanks!

why, have you seen the stock one. probably not because its actually two (2) three into one headers or (six into two) they actually are more than adequate unless going over 300hp or so.

[SvenRasta]

this entire post is
12v and 24v are both VR6 motors...difference is of course #of valves and a variable intake.
12v=174
24v=201

[arjetta]

So for those of us keeping score it all boils down to marketing.

the V6 you posted a head flow picture of is actually NOT in a Golf (or anything else built on the A4 platform [thats the A4 chassis, not the Audi A4 car])

it is a 30 valve motor mounted longitudinaly in the vehicle (tranny behind rather than beside)

the V6 found in golfs are a 24v VR6 ... single head design

[donlj]

vtechTHIS: Yes and I'm going over 300hp, that's why I'm asking even if I don't agree with you.Did you see the exhaust manifold once used? you can see where it has suffered from the heat because it makes a "L" so the gaz is slowed down, and the engine gets hotter also. I saw mine in january and now that i'm going to more than 300hp I want one but I can't find it... there's no enough clients for the companies in Europe to produce them

[Vee-aR-6ix]

The 24v motor also has a variable length intake manifold. I don't think I saw that posted yet.

[M this 1!]

so did the MKIV 12v, but that'll just confuse more people.
