can anyone explain what is a "W8" engine?

apparently something 'new' from volkswagen...
i did some googling, but only found

>> the VW said -like a V8 only more compact

and another site -- like two V4's stuck together in a W shape..

now (looking down on engine)

regular V8 something like
O | O
O | O
O | O
O | O

so two V4's looking like W would be
O | O O | O
O | O O | O

but seems (to me) that would require two Cranks (two flywheels?),
2x camshafts...... and so, be not that much smaller, but
heavier and more complicated than the V8


???

You've got the right cylinder configuration but only one crank is required. Think not a true "W" but more of a fan.

The engine mounts with the crank in the traditional RWD orientation.

Do a search on "Volkswagen W8". You should find some good pics.

This is a link to an exploded picture of the W8

I still think it looks like an X. Does this thing have two timing chains??

Looks like 3 timing chains to me; one from the low crank to a high pulley, and two more from that pulley the valvetrains.

The W8 isn't really a W like the VR6 engine isn't really a V6. Real V-layout engines have two banks of cylinders, and a head and valvetrain for each bank There's about 60-90 degrees of V angle between the banks. A VR6 has a 15 degree V, and since it only has one head, it's really a straight-6, just a little staggered.

Think if the W8 as a two very narrow-angle VR4's, whose centerbores aren't on one line, sharing a common crank, and set apart like a two-head V8. Sort of.

thanks to All.....
the pictures were pretty but *i* couldn't tell anything from them...

5Speed seems to be saying:

two banks of 4, the 4 on-line, one crank between ...

they're not on line, the whole block can be 'squished'

no 'w'........

I am not sure. I would love to see a model of one. I built both the wankle and V* when I was a kid. This one should have all kinds of fun parts.

Not to put down VW, but I can't see spending $37k+ for a Passat! You're well into the price range of some very nice cars and unless VW did some major changes to the handling characteristics of the Passat I test drove, it just can't compete.

On the other hand, if the W8 is that much better, they shouldn't be calling it a Passat. It's hard to break out of the mentality/price range of the other Passat models.

I'm sure the W8 is a fine engine and the car is well thought out like other VW's, but is someone shopping for a BMW, Audi, Lexus, etc. going to want a Passat?

i suspect that Is the plan.... & that VW loyalists wanting to move up...

what's a little odd is they're competing with their own Audi, no?

Ah, HA! I can see VW's dilemma, marketing the car as a VV in the U.S.

Introducing the new VW VV! NOT!

Imagine marketing it in any Asian market as the Dahbayoo... ;)

I'm reminded of slow sales of the Chevy Nova in Spanish speaking markets.

The current Passat is on schedule to be shelved in 2005 when a B6 platform car will be introduced. Armchair analysts say VAG is testing the waters with the new engine... only the early adopters will go for it and the aftermarket will wait and see.

The enthuiast community agrees with the comments I've seen here: $38 G's is a lot of money for a mere Volkswagen. Not to mention the forthcoming Phaeton S-class contender at $50 G+. Meanwhile Audi cheapens their cars in the name of making the brand more sporty. Instead of bringing the sport versions of their lineup to North America (sigh, RS4...) they neuter the potency of the real rides without removing the badges. It's as if VAG is trying to switch their markets on one another.

If only I could get the interior out of a Skoda Superb for my Passat...

Well, they could hardly call it the V2 now could they? Think of the bad publicity THAT would generate. WOOT!

oy... shoulda thought of that....
and if only one of the articles i read had thought of that...
they (some) said, "two v4's stuck together to form W"....it's
two v[r]4's ..... so double-v

I think a premium VW Passat could rival an Audi A6 for quality an amenities, but probably not snob appeal. I'm am a bit baffled by VAG's is plans for these two rapidly converging brands.

A $37K Passat W8 is no farther out than a $32K Camry (Lexus ES300), or a $61K Land Crusher (LX470). Or course, the MOST rediculous vehicluar delusion of grandeur was FoMoCo tacking a Continental kit on a Granada and calling it a Lincoln.

I don't doubt that Passat's can rival other companies for quality and amenities, but the Passat I test drove came nowhere near the handling and smoothness of a BMW 325. At $37k, you're talking 10 grand more than the base 325i.

Obviously the W8 will improve the 0-60 times, but are they improving the handling? We'll have to see.
