W8 vs. V8 W8
V8
The W8 block is smaller, lighter, and most importantly has 8 cylinders. Volkswagen failed at their DOHC W8 because of the cost. However, what if GM engineered a OHV W8? Efficiency anybody????
Discuss.

Unecessarily complex. What do the heads look like?
I think this was designed so that they could fit a V8 in a transverse FWD application.
New ideas and technology only stick if they are better in all areas such as performance, cost, reliability and size.
I read that GM is now working on a direct injected V8. Not sure if it's LS based, or a completely new design.

thats actually kind of cool looking, not to mention you could make a W10 look about the same size as a v8. except for the fact the cylinder heads are probably huge. not to mention the possible advantage of turning lateral force into rotational force in 2 more different directions on the crankshaft.

making 1000hp on 16 cylinders will always be more reliable then 1000hp on 8 cylinders considering both motor are made properly
let me simplify that. if you need to lift up a very heavy table, who will be more tired at the end of the day, 8 people or 16 people lifting that same table ? yes both of the groups will be able to lift it but the 16 people group will be able to do it more times.
yes, if the 16 cylinder motor is not built properly it will not be able to make 1000hp reliable but in case of the veyron motor it is.

I would have a look a Narrow angle V engines if you are intrested in W engines. VW VR6 and R32/36 engines are pretty impresive. heads are BIG though! also keeping them cool is a BIG problem as you have very long exhaust ports.
Also there was a W8 engine used in a W8. hoever i heard the bottom end was very weak as it could only run 3 main bearings!

The W motors are a neat idea, but I don't like the fact that you have different length intake and exhaust ports. How the hell do you tune that for power?? And how does the crank take power pulses from so many different angles?? And like stated above; the crank loses room for main caps being so short with so many rods strapped to it.

I just think the W16 is overly complex and unjustifyable from a business standpoint. Now a VR8 like the VR6 might be a more interesting notion.........

Yes, all three are much more valid options than the VW quad turbo W16 when it comes to price, packaging, parts support, etc. Of course we could get into the powerband/torque/useable power argument also.
