8 cylinders in a smaller package than a V8. Volkswagen offered one in the Passat in 2001-2004 that made 275hp n/a.

One head = one bank of cilinders. They have two heads, one intake side, two exhaust sides, which makes them a stupidly designed V, and not a W.

Even if it did have four banks (it doesn't), it wouldn't be a true W since those have three banks.

>One head = one bank of cilinders
No, one head = two banks of *cylinders* you are probably stupid enough to consider the V5 an inline engine.

>>17857362
If that is how you spell cylinders I don't think people will take you seriously.

>>17857369
Quit your delusion, it's not a W. It either has too much (false) or too little (true) to be a W engine.

The VAG "V5" is actually a VR5. First of all, it's an unholy abomination that only deserves death. Second of all, it's a VR, or inline V. Technically speaking, it's neither a V or inline engine, but both at the same time. However, it shares most of it's trait with the inline five: single head, single direction of head flow, and rectangular packaging. It's only considered a VR because of the slight V angle.

>>17857378
It's cilinders in my native language though. When somebody says cylinder, I think of German, not English.

A bank of cylinders is defined by acting in the same plane not sharing the same head. You could make a single head LS it's not going to make it a single bank.

A W engine can either be a triple bank of cylinders, or a "Double-V" (literally what "W" means - "VV"). They are homonyms.

Cooling, possibly oil dispersion as well. Either the Sopwith Pup or Camel, maybe both, was actually very renowned for its maneuverability due to the torque of the engine aiding in roll control, though I'd imagine any rotary radial would have that advantage so long as it's designed well.

>>17857875
Please cite your sources for that. There ARE still flying examples equipped with rotary radials and they manage to do just fine. The more likely issue is the lack of standardization of construction methods and quality. Not only were engines in their relative adolescence, but we're also talking about airframes constructed of wood and cotton here in a time where metallurgy wasn't nearly as advanced and precise for things like fasteners.

>packaging
For fwd applications, sort of. They fit where an I4 can, that's the only thing they have going for them. RWD, they're just shit to work on 99% of the time, and in both FWD/RWD applications you run into a lot more trouble finding space for accessories like the alternator, power steering pump, aircon, etc, all of which are easier to package on an I6 than a V6. More room in the engine bay on either side of the engine is nice, too.

I'd argue against weight, also - consider that each bank needs separate exhausts, there's nearly twice as much timing chain/belt bullshit up the front, balance shafts on certain engines, and with turbo systems you're usually looking at shitty plumbing to a single turbo or a pair of turbos, which means more intake piping, more parts stuffed into the increasingly packed engine bay, and more shit to go wrong.

Now, don't forget the benefits of an I6 either; smoother power delivery without balance shafts or fucking around with electronic/vacuum operated engine mounts. Better exhaust note. Less complexity. Easier to work on. There's probably other stuff I've missed, but it all adds up.

So for almost every RWD application, a similarly engineered I6 will be objectively superior to a V6.

>>17856306

Sleep tight brapper

>>17863440
Sure,a transverse V6 has shit packaging in terms of a crowded engine bay.ever seen a transverse I6? They're even worse. That's the problem with fitting six cilinders transversely. V6 does it better though, as evidenced by the very small amount of transverse I6 models.

In longitudinal form, the V6 is superior in an engineering sense. Assuming you've got a separate cam and accessory drive, then it's literally bolting the exact same accessory pack into the front - and the V6 has more frontal surface area to mount stuff to, meaning you can reduce it's width. Especially important: the V6 is a lot shorter, so you can reduce he engine bay size by a lot. This also puts the weight closer to the firewall, which is good in a RWD application. Anyways, the accessory point is moot once manufacturers move to 48V accessory drives, like Mercedes pioneered on their new I6.

Each V6 bank needs one I3 exhaust. This weighs about half of a good I6 setup, which should separate even and uneven runners for optimal pulse tuning. Sure, the timing chain is longer, but the cams (assuming DOHC) are half the length. However, the torsional loading is a lot higher on the I6 cams, which means they need to be overbuilt significantly, and that added mass requires significantly heavier cam sprockets. In the end, a V6 valvetrain weighs about as much as an I6 one.
The same goes for crankshafts: twice as long on the I6, with a higher torsional load. This means that a V6 crank is significantly lighter.
Modern I6 engines also have multiple compressors, so you point is moot. Also, a hot-V6 would be great for packaging.
The real savings are in the block weight though. Imagine cutting an I6 in half lengthwise, making two I3s. Now slide those together as a V6, and you can clearly see that they'll share a lot of webbing in the bottom end of the block, this is where you can make big weight savings as an engineer.

>>17863440
>>17863622
NVH engineering is so far ahead of what it used to be, that by using a proper 60 degree V6 you can have very little intrusion into the cabin, at the cost of next to no lifespan. Better exhaust note is subjective, and good example of a V6 exist - there's not a lot of sixbangers that'll sound better than a Busso at full song. Less complexity is not true, the only added part is balance shafts if you need them.

In the end, for performance, only two things matter: weight and size.V6 engines are lighter, and smaller, which means you can put it's center of gravity further back (in a front engined car). This centralises mass (=better rotation, due to less rotational inertia around the center axis of the car), and puts the center of mass further backwards, which is advantageous in a RWD car.

The only use of the I6 is as a USP (unique selling point). It serves BMW very well in this role, and even with the objective superiority of the V6, I wouldn't even consider to buy a BMW with one. Mercedes and Jaguar are moving there back to I6's, they've got a lot of history too, and quite frankly, their V6's are mongrels (especially the Jaguar). Mercedes has solved some of the I6 packaging issue with their 48v mild hybrid system. However, I think this step is mostly because of their existing engines: the M270 and Ingenium. Their 6cyl engines used to be derived from their V8, where a V6 makes perfect sense. However, coming from these I4's, a V6 makes very little sense, they both scale much better into the I6 format, with a lot of parts commonality (and less engineering cost). It's also perfect for marketing for both companies, again given their history with I6 engines.

How about this turd

2l sohc 8v making 115bhp. In 2005?
Came in like 3/4 generations of Passat, Golfs and A4's. Unchanged performance since lobbed in some ancient Audi back in the early 80's. That they had the brazen cheek to keep this shitter in their line up for so long is amazing in it's own right. Not to mention the fact that it came in the mk3 GTI back in the late 90's. That was at the same time a simple EK4 Honda came with a 164 bhp dohc 1.6 beating it in every way imaginable.

>>17857318
More like 6-8hp. horse at running speed is around 16-18 hp

>>17863930
The little shit won't ever fucking die though.
All the electronics around it will, but that engine will last until the end of time.

>>17857131
I had a 2.7 up to 170K. No sludge with regular oil changes. The problem was the electronics not the mechanics

>>17862527
and it is GLORIOUS
0.34lb/hp/hr fuel consumption is phenomenal; it's equivalent to 40.7% thermal efficiency, which is vastly superior to its contemporaries. It wouldn't be matched in a large engine for another 40 or so years.
Just under 0.88hp/lb is pretty damn good too. If a V6 Camry made that, it'd have 338hp. Considering that it's an aero engine and a diesel with probably absurd levels of strength and reliability compared to a car engine, and that it's more than half a century old, Napier engineers should be impressed with themselves.

Eh, I would not call it "Dumb" or "bad" its simply reliable. Reliable engines tend to stay around for a long damn time. I know you could get a 2.0 in a jetta until 2015. Most 2015 rentals would have had the 2.0 with a full 115 hp.

I was on the jetta forums and some fuckboi with a 2015 2.0 8v had it slammed and riced out and was bragging how "the 2.0 is fast" I got pulled for 110! im like my dude...everyone here with a 2014+ 1.8t would smoke you so fast. Fucking idiot. stockholm syndrome I guess. any modern car can do 100-110 if given enough room.

Hell, Ford was still putting Windsor 5.0's into explorers as late a 2001. That engine was like 50 years old at the time with no major improvements. Just EFI and a better head.

>>17863930
VW made non-turbo diesels until not that long ago, they just give people a lot of (wrong) engine options to choose from.

>>17865888
...That's not a diesel.

>>17855028

Because it's literally ripping itself in half as it operates.

>>17865858
You can still buy the Ford Windsor as a crate engine. They've had it in production since 1961. Of course, you can buy a SBC crate engine, too, and that's been coming off the line since 1954. (Albeit the new ones are hecho en Mexico). They've got a few years to go to catch up with the VW air-cooled engine, though - 1938-2003.

Some of the aero engines still in production are pretty damn old. The Lycoming O-320 dates to 1953 and apparently hasn't changed too much. The O-235 are apparently still for sale - certified in 1942...

>>17865921
Yeah, I guess I mean production vehicles. But yeah, ive seen a lot of built 400-500 hp 5.0's around here.

Although I did see a guy with an old mustang, with a 5.0 coyote transplant. Interesting considering he was a boomer.

>>17865898
I know, I wasn't saying it is.
You could buy a Golf Mk V with a 2.0l non-turbo diesel with 75hp, literally 90s Mercedes tier.

It's more a packaging issue desu. Also DOHC's are expensive and 4.6 SOHC's are slow as hell.
4.6 and 5.4 Intecs are getting cheap FWIW.

Where as junkyard LS's are actually usefull.
