Can we talk about the obvious superiority of VR engines over any other engine design?

Literally the only downside is that your bore size can't be too big without widening the block

how?
post exhaust ports please?
>>
>>14111828
As requested. It's due to how all intake valves are controlled by a single camshaft, and all exhaust valves are controlled by a single camshaft

It will probably become a thing again now that turbos on non-sports-cars are becoming really widespread.

Atkinson cycle engines (Miller minus the forced induction) is common on hybrids afaik (they make up the power less with the electric motor).

Toyota is coming out with a non-hybrid atkinson cycle v6 on the Tacoma. Not sure how it won't be gutless, unless the compression stroke is only mildly shortened.

You fucktard, tell me an engine design that isn't unbalanced. VR6s are actually more balanced than V6s

The best thing about the vr6 is the sound and you loser Hans haven't put a video of the sound.

My dream car is a Audi TT with the vr6 engine with a aftermarket exhaust. That shit sounds better than any v10 lambo.

I'd also add that with a VR6 you end up with asymmetrical combustion chambers which are not great for power or emissions.

Plus you end up with one bank having a negative bore offset and one with a positive bore offset, so the one with negative offset has much greater friction during the firing stroke. Pic Related.

Absolutely disgusting.

Either be a real V or become an inline. Choose a side -- No in-betweens allowed. It's engine equivalent of politician without an opinion.

Not wrong, though.

There's really no physical advantage of VR and W engines other than really narrow V engines.

That's not true. A VR6 has two cams but at the same time has two banks of cylinders. Each cam deals with the intake and exhaust valve of each bank of cylinders. It's equivalent to a SOHC V6 so it's kinda misleading to call it a DOHC, even though technically it is.

The VR6 is able to have exhaust and intake on their own sides because it has unequal lenth runners inside the head. Pic related.
>>
>>14114042
the advantages have been listed in this thread
>>
>>14114090

And yet most of them are theoretical advantages not seen in practice. Also, the benefits that it does have are offset by the negatives.

Bottom line: There is no point to VR/W engines.

>>14114472
Engineers are paid to make what ever their companies want them to make.

You think VW engineers lobbied to make the Veyron?
>>
You know what I hate about the VR6? It's only available in FWD, or FWD biased AWD. It'd be great if it were available in an FR sportscar,it'd be kinda good there. Problem remains that all VR engines are pigfat, like, inline six tier. To compound this, VW went full retard making them out of cast iron.

Problem remains that they take up the length of a comparable inline six(almost), the width of a narrow V6, combined with their massive weight, and huge internal complexities
>asymetrical combustion chambers
>balancers(which an inline six doesn't need)
>uneven intake runners
>thrust loading
As an idea, I prefer Volvo's inline five to the whole problem of "guys how do we fit most of this inline six into this FWD car". Packagibg is ten times better - enough to cram a turbo next to it. Both are unbalanced, but the inline five is way easier to build, with a way better head design, and at least it can do proper independent cam phasing.

>>14112825

About the only good thing about VR6 is the noise it makes.

Expensive, mechanically complex, heavy, under powered and bad gas mileage everything in one package.

>>14115318
Mechanical engineering. Couple of my friends started interships at VAG (Audi sponsors our Formula Student team, and hands out interships like candy). Even they can't explain the VR - especially the 5.

Then what's the benefit if it's not actually shorter and each bank has its own camshaft? It's the size of an inline with the complexity of a V.

24v vr6 owner here
Sounds fucking beautiful with the magnaflow
Its shit off the line, lots of cars have better 0-100 but what eves, it is a nice commuter if not a little thirsty for my liking.

The car is just a killer on the Coquihalla Highway, it sits comfortably at 140km/h (97mph for you American) and doesn't flinch on the inclines where almost every other car is slowing down.

beautiful engine, the Jetta would be perfect if it were RWD, but FWD isn't that bad as a DD

These engines are heavy and don't make that much more power than the 1.8t. Tune the 1.8t a little and you have a better engine.

Vr6s never came in the nice 20th ae edition gtis or the 20th ae gli. So the vr6 was always stuck in the blander looking vilkswagens. So throw those in the trash.

Fuck the vr6 the only thing good about it is the sound but even that gets annoying after 5 minutes.
>>
>>14115988
Except the vr6 has 2 less cams than a v6? Isnt that less complex right off the bat? Its also shorter than an equivalent displacement i6?

Youre making this hard to read.

In no possible way is a 1.8t better than a VR6. Just because you can overboost the fuck out of the K03 turbo and make more power than a stock 12V VR doesn't make it better. Also there is no such thing as a '20th AE GLI'. The 2003 GLI acutally got the 24V VR6, which I'd take any day over a sludge machine 1.8t.

Also I guess you would consider the Mk4 and Mk5 R32's pretty bland since they both came with 3.2 VR's? Alrighty then.
>>
>>14122781
Look at the pic I posted. That's a 20th anniversary edition gli. Rekt.

The R32s only had 240hp which is pathetic when the 2.0t could easily match and exceed that power number easily. Same with the 1.8t.

Face it the vr6 is a turd that sounds good for q while
