Too bad VW killed the W8. It was very expensive to make because of the special castings required to produce the W block. And it requires far more machining than a standard V8 block.
what did they use to build engines before the days of computer cnc cutting machines. was it more hand operated cuttign equipment using lever assisted mounts. it would be great to see an engine built without the use of cnc machinery
@210482fmj there's an F1 documentary from the turbo days and they built a prototype by carving a mould from wood which they then use sand to create a a casting. It is this sand casting that is directly used for creating the block. they still had to machine everything later on
actually only 20% shorter since the cylinders are only overlapping slightly. and only "Just" lighter BTW. nothing earth shattering. rotating mass is still the same weight.
cooling is not an issue CAD design precludes any deficiencies.
wall thickness has to account for the type of material as well as thermal cycling.
also basic machining is no issue, the "art" is in the casting(s). once cast, conventional techniques are used.
the friction of 2 additional cams? is more than the 16 rocker arms
Could you make it like a QOHC (4 cams on each bore) so you dont need rocker arms? I know it would make things more complicated for timing but you would reduce heat wast.
The cylinder wall thickness is determined by mechanical stresses (peak, and average cylinder pressure) more than heat transfer issues. So really the wall thickness should be similar in any engine designed to run at the same compression ratio (with the same bore and stroke) regardless of cylinder configuration. Though in a sense you are right since the W cylinder layout would likely complicate coolant flow passageway paths, especially in the cylinder heads.
I unfortunately have to sell my W8. It's incredibly beautiful...black on black, leather, Remus exhaust, etc. PM my if interested. I live in San Diego, CA. Thanks.
The W8 is a novel if somewhat extravagant effort. You're trading size for complexity. The heads to these types of engines are absolute works of art and must easily take 5 times the machining when compared with a traditional engine.
And you know there are no weight or space advantages because you've researched this ? Have you ever seen one of VW's V6's in person? The width of the VW V6's vavle/cam cover teal is barely bigger than a plain jane inline 4.
@JapanScott1 yes, I have researched this, they are an evolutionary dead end as well as being riddled with design and quality issues (like all german products), VW discontinued them a few years ago... they make no more power and are actually deeper (slightly narrower) than a reg V8..
@westexpipeliner W8 can have the same power and torque like an normal V8 (wich have the same capacity (litre) and is in that category where the W8 is) and its aproximately 25-30% lighter than a normal V8 and its shorter, so it can be placed into smaller cars and less weight = less fuel consumption = reducing costs.
So the W8 engine can have the same power and torque like a normal V8 engine, but W8 has aproximately the weight and the size like an average V6...W8 is lighter than the smallest V8.
I think it actually goes further then that, a W8 has a greater volume to surface area ratio then a standard V8, hence a better volumetric efficiency! Nice engine!
@wpeti890720 It is hardly approx. the weight of a standard V6, unless those additional connecting rods, pistons are wiehgtless... i suppose they aren't though. The block itself isn't smaller - its just shorter. So it is as heavy as a V8 but only shorter by, say, 20% (at most). It would rather be interesting to know the vibration level, and the harmonics that are generated compared to a standard V8. Apart from that i see only VWs urge of diversity in using them.
@westexpipeliner I agree, there is no benefit to making an 8cyl engine this way, as you say it is much more complex and expensive to build, yet there are no power, weight, efficiency or space benefits over a standard V8 or V6... VW were showing off (as usual) when they designed this engine, pure and simple....
@isamike FPV GT, 315kW, 1852Kg, 0-100km/h: 5.4-seconds, compared with the Audi RS4 B7 which has 4 wheel drive and still weighs 200Kg less and doesn't need turbo chargers to get 310kW out of a 4.2L engine. The Audi accelerates also in less time.
And if I look at the now 10 year old Audi Audi RS4 B5 V6 turbocharged had only 280kW but it also weighs less even with 4WD and is faster from 0-100KM/H. The FPV GT is heavy as a lorry and has a lorry engine with little kW for it's displacement and it handles like a lorry. Really really bad due to it's heavy engine.
@superamerica1981 it is better. it's a proper engineered engine, it is smaller, lighter and uses less fuel by generating more power and torque. it is german. a american V8 is something out of a museum and nobody in the world, living outside the bubble uses it for cars anymore in these days. they are too heavy and use too much fuel and why would you feed 8 cylinders fuel to create 180hp if 3 are enough to generate this power and then even perform better because everything weighs less? wake up!
@huramentzefix Look at the new FPV GT in Australia, it uses an American sourced 5.0L mustang engine that makes 330KW (Supercharged) it is a very good engine.
If you want a proper engineered car then buy something german. But no matter what, nobody buys the FPV GT nor the Audi RS. They are image cars for the manufactures and they just make a loss with them. The future are 4 and 3 Cylinders with displacement of 0.8L to 1.6L and every car manufacturer that doesn't produce them will disappear sooner or later. The V8 is dead and the V6 dying!
@huramentzefix youre into a whole differnt arguement, FPV, from memory are majority owned by prodrive and if they were just making hero cars at a loss they would go broke. my arguement is that your statement about american engines being museum pieces is wrong. what you are now trying to argue is a whole differnt point.
@huramentzefix v8 is dying i wouldnt say dead but germans perfected the v8, the americans did not. and germans diesel motors are what will take over. the tdi's and what not. cleaner and powerful. just my 2cents
@discocreator76 i have. an american v8 is still strong but once you get into the 100k to 150k miles they are junk. germanys v8's last a long while. like in the 200k+ miles. i'd be around both. the germans just make better parts, becuz they do it to be better they want to be the best. americans do it for power and money. its just might be me tho idk. i've never had problems with a german made car but i have had a TON of problems with mexican made vw's. how is it overrated? they perfect things.
@VcottntailW American engines are no junk after 100k miles LOL, I had a Firebird with 241k on the clock and it was still perfect, plus, conversely, I had a Golf (Rabbit) with 81k and the engine was dead, Ive owned at least 10 german cars in my time and came to the conclusion they were shit, always had trouble with them (expensive trouble), I buy Fords, GM and french stuff now and get no problems (nothing major, anyway)....
@VcottntailW I agree. German engineering is simply better than anywhere else, well? maybe swiss is just as good. A lot of R & D goes into german stuff to make it right. I am not saying American stuff is crap, its actually quite good. My daily drive has a buick 3.8L v6. Its simplicity is its key to longevity and reliability which is what america is good at. Btw I am aussie so I am not biased and can see the facts clear as day. German engineering FTW!
If you look up the m5board you can watch this engine beat the brakes off EVERY CAR THEY PUT UP AGAINST IT INCLUDING YOUR MENTIONED GREAT GERM-men sports crap...Stop being stupid STOCK NUMBERS DONT COUNT TO REAL WORLD ENTHUSIAST.
@peanuts2105 I get do tired of arguing this point...um you brought up the jag 5.0...WDFDU THINK IT CAME FROM?! YKW um one of the FASTEST supercars in the world uses A FORD V-8!...it's swedish um....what's it called....????? OH YEAH THE CCR/CCX...
better fuel vaporisation, air travel easier into cyl/ better breathing, bigger valve surfave than 2 valves, exhaust gasses flow more freely, more power per fuel uniit.
a multivavle engine is always better than a old 2 valve engine
Basically this is two VR4s welded together to spin one common crank-shaft. Quad Cams as well; I wonder how reliable those long valve pushrods are at higher rpm, since they're twice as long as the shorter ones closer to the cams/cylinders.
is there any sound or performance differences between the w8 & v8 engines? were there any disadvantages that made vw stop the passat having this w8 option?
yep pretty much a v8. its got 8 cylinders. i used to drive a 2004 wagon. i would not buy it because i wanted a v8 but because of the look oh and maybe the heated seats haha. i reckon pretty slow off the mark but once going its got some balls. if you want a v8, go buy american. but still a nice car for the missus.
@samoanshinobi01 "If you want a V8 and go buy American". Are you mad?! The best V8's in the world are European. BMW's 4.0 litre twin turbo V8 in an M3 is a work of art; light, highly responsive and clean. Audi's RS4 is quite possibly the best V8 in the world due to the fact it revs to 8000 rpm and it's light, so light, it sits in the nose of an RS4. Try doing that with American "pig iron". Lets not forget Jaguar's immense 510bhp 5.0 V8 and Merc's 6.0 Bi-turbo. Europe is where the talent lies
I agree. Throughout history, the Germans have lead the world in mechanical ingenuity. American v8's still use pushrods. Unless you count the Cadillac "Northstar" v8, but that one won't be made anymore.
@razioth I have to consider the Ford 4 cylinders the best. The bottom ends of the 2.3L and 2.5L Lima motors can handle up to 8K Rpms. The factory crank shaft can handle 700HP. The motors are as we know right now capable of handling 425+Hp but the tranny can't handle it.
Most of all the motors are just about imposible to kill. They last upwards of 250K to 300K+ without rebuilds.
Personally, I don't like Ford. I like Jeep and Dodge. >.>
@pancakewafflebacon Pretty much. There is a reason why Ford kept the old Lima motor around as long as they did. Then they sold out to Mazda's Duratech motor.
there are much better engines which are electrical engines.. they are most efficiant and more ecological.. russia showed something like this.. cranes always uses electrical engines but we can't use best technology becouse of seeknes of power to rule of those who keep them hidden.. have a good day
Its a V8 with offset cylinders, sounds like a V8, goes like a V8, just a bit shorter in length.
A big advancement for the internal combustion engine would be the phasing out of the poppet valve, and using coates patented CSRV, now that would make this engine far more efficient and also allow for higher compression and far better gas economy.
I dont understand the argument here. The point of the w setup is in packaging. instead of a small car only being able to fit an I-4 or v6 motor, It could now fit the w8.
@jgkov49 its a dohc v8 but its pistons are spaced closer together to allow it to fit in the space that say a v6 would take up, so yeah it is just a compact v8
@ZenithRacing ooo ok....so would i beable to get a w12 engine and put it in a car that can already fit a 454 chevy big block(1969 camaro) and since its a w12 it would make more pwer then the v8?
@redghost105 yea it would make more power but not as much rpm id take the 454 anyday. and if you put a w12 in a classic American car your gayer than adam lambert. those cars are supposed to have v8
i just found out about this engine brand called nelson racing engine
but the engine is a twin turbocharged 427 and pumps out 1150 HP and 1170 TQ with pump gas...my favorite part of having a car that can pump out 1750hp on racing gas is paying th insurance for it ahahha
another automotive marketing effort that didn't pick up success, as many predicted.
expensive to produce, and more costly to maintain than a V 8. Less performance compare to a charged V6. Fuel economy, no gain. If you are a performance enthusiast like me, you will stay away from it. 2 cams on an in-line or 4 cams on a V is enough trouble.
I remember you. we talked about pushrods stuff in another thread. Now, I agree that VR5 VR6 ARE great design: shorter than I6, much thinner than V6. The VR6 was even in Golf Mk 5 GTI version, a model I liked very much.
That being said, a W8 is a different design. It looks like 2 V4 pieced together very tightly, with 4 cams each operates valves for 2 cylinders. Very complicated.
With the direct fuel injection & turbo charge technology VW has, I think future product lines will be all FSI, TSI,
TDI, etc. Small engine, cc, light, 100bhp/lt output, and very fuel efficient. VR6's era's gone, due to emission. W8 is still questionable, unless they become FSI. I would prefer a Japanese I4, I6, V6, and easily get 100 bhp per liter. But I live in Asia and I am biased, ha.
Do you know that Honda officially discontinue the Civic FD2 Type R? The next type R, whatever it is, will have to be direct injection, or maybe turbo'ed in the same time.
@beboybo im sure somebody out there has made one. it would be big, but not that long. a bit longer than a straight six, and definitely much wider, but im sure theres cars that could take it.
yeah. like two V-12's. i read it in a magazine a few years back. it achieves over 1000 horsepower but can still drive on streets at an easy 35mph or so without damaging the engine. sure, you can get 1000hp by modifying a V-8, but if you travel at 35mph with it under your hood, it causes a lot of damage..
W8 sucks, just like VR6, cooling sucks, we got like 8 vw touaregs back withing 6 months because of a blown piston/cracked head, and whatnot, due to the bad cooling properties
All VW products for a long time have been poor, I'm in the Motor trade and have seen unforgiveable design, material and build quality problems with VW cars. Even the Koreans make better cars than VW nowadays it seems!!
VW has taken a turn in quality for the worse, but they still have good innovations. Only problem nowadays is that they have too much pressure to get the cars out there. But they still did not make a huge error like toyota with their Prius:P
Its just slightly wider while its short as an avarege v6 - Probbably it is also lighter. So its not smaller all the way around an the pistons are not shaped as a w. the pistons have the same shape as in any other piston-enginge. As you can see in the animation.
Well you aint touching my car then. Its actually a W8. Its two 15 deg V4 put together in a 90 deg V. The gain is a 8 cylinder engine that are no longer than a average V6. On the downside there are big ends on the rods that are quite narrow ...
the car doesnt need that much torque to move, bugatti apparently bought that idea to be able to use it in their car, plus the Veyron is AWD that helps alot. if you think about it the way they have this engine setup its like having to v8s almost. all i know is in Forza 3 it does the job
fucking piece a shit it is ,, a nightmare to work on

better fuel vaporisation, air travel easier into cyl/ better breathing, bigger valve surfave than 2 valves, exhaust gasses flow more freely, more power per fuel uniit.
a multivavle engine is always better than a old 2 valve engine

@naturalyshocked ok thank you

Basically this is two VR4s welded together to spin one common crank-shaft. Quad Cams as well; I wonder how reliable those long valve pushrods are at higher rpm, since they're twice as long as the shorter ones closer to the cams/cylinders.

yep pretty much a v8. its got 8 cylinders. i used to drive a 2004 wagon. i would not buy it because i wanted a v8 but because of the look oh and maybe the heated seats haha. i reckon pretty slow off the mark but once going its got some balls. if you want a v8, go buy american. but still a nice car for the missus.
samoanshinobi01 1 year ago
@samoanshinobi01 "If you want a V8 and go buy American". Are you mad?! The best V8's in the world are European. BMW's 4.0 litre twin turbo V8 in an M3 is a work of art; light, highly responsive and clean. Audi's RS4 is quite possibly the best V8 in the world due to the fact it revs to 8000 rpm and it's light, so light, it sits in the nose of an RS4. Try doing that with American "pig iron". Lets not forget Jaguar's immense 510bhp 5.0 V8 and Merc's 6.0 Bi-turbo. Europe is where the talent lies

I agree. Throughout history, the Germans have lead the world in mechanical ingenuity. American v8's still use pushrods. Unless you count the Cadillac "Northstar" v8, but that one won't be made anymore.

razioth 1 year ago
@razioth I have to consider the Ford 4 cylinders the best. The bottom ends of the 2.3L and 2.5L Lima motors can handle up to 8K Rpms. The factory crank shaft can handle 700HP. The motors are as we know right now capable of handling 425+Hp but the tranny can't handle it.
Most of all the motors are just about imposible to kill. They last upwards of 250K to 300K+ without rebuilds.
Personally, I don't like Ford. I like Jeep and Dodge. >.>

Its a V8 with offset cylinders, sounds like a V8, goes like a V8, just a bit shorter in length.
A big advancement for the internal combustion engine would be the phasing out of the poppet valve, and using coates patented CSRV, now that would make this engine far more efficient and also allow for higher compression and far better gas economy.

another automotive marketing effort that didn't pick up success, as many predicted.
expensive to produce, and more costly to maintain than a V 8. Less performance compare to a charged V6. Fuel economy, no gain. If you are a performance enthusiast like me, you will stay away from it. 2 cams on an in-line or 4 cams on a V is enough trouble.
golferchin76 1 year ago
you're wrong.
VW sold millions of vr5 and vr6 engines, mostly vr6.
mounted, in vw, audi, skoda and seat.
this engine is a dual VR engine.
simply an evolution.
the passat wasn't build for a fullsize v8, like in the A8.
so only a VR engine could fit.
the VR concept was very good, operate 2 'banks' with only 2 cams.
the original golf mkIII vr6 is still a very wanted car.
naturalyshocked 1 year ago
I remember you. we talked about pushrods stuff in another thread. Now, I agree that VR5 VR6 ARE great design: shorter than I6, much thinner than V6. The VR6 was even in Golf Mk 5 GTI version, a model I liked very much.
That being said, a W8 is a different design. It looks like 2 V4 pieced together very tightly, with 4 cams each operates valves for 2 cylinders. Very complicated.
With the direct fuel injection & turbo charge technology VW has, I think future product lines will be all FSI, TSI,

TDI, etc. Small engine, cc, light, 100bhp/lt output, and very fuel efficient. VR6's era's gone, due to emission. W8 is still questionable, unless they become FSI. I would prefer a Japanese I4, I6, V6, and easily get 100 bhp per liter. But I live in Asia and I am biased, ha.
Do you know that Honda officially discontinue the Civic FD2 Type R? The next type R, whatever it is, will have to be direct injection, or maybe turbo'ed in the same time.
Audi, skoka, and seat are all vw subsidiaries.

Its just slightly wider while its short as an avarege v6 - Probbably it is also lighter. So its not smaller all the way around an the pistons are not shaped as a w. the pistons have the same shape as in any other piston-enginge. As you can see in the animation.
