Try this link, all you ever wanted to know.

About 2/3 down the page under Engine Packaging. Links to VR6, W12, W16, W18;

Also a link further down under Engine Smootness.

Not really a W configuration but W = Double-U (or Double-V).

interesting how this thread got moved into the 8's>Modular section.
It's about almost everything but an 8 (6, 12, 16 and 18 cylinders).

OK, somewhat modular in concept but it's a bit of a stretch to place it here.

You need an others section for stuff like this.

Kinda had me confused too, until I started thinking of it less as a 'W', joined at top, but more like a 'double V', with the bottom of both 'V's connected, which is what it really is. Looked at from the end, it doesn't really look like a 'W', but that's the power of marketing I guess...

is it like a V inside a V?

RAPTOR · 05-01-2003, 22:23

No not really,

It is 2 V's with the same lower point.
One rotated 15 degrees around the other with a fixed lower point.

There is only one crankshaft, here's a pic of the W12 crank. Note the slightly offset big-ends on each common crank pin.

so how does it work i dont get it is it like a 2 engines inside each other cause how caus eit run on one crack would it have one then one about it?

An engine inside an engine is one way to think about it I suppose.
Look at the photo in my first post, the one with the cylinder heads off.

You could think of this a 2 V6 engines. One rotated a small amount (in this case 15 degrees) around the other and pushed forward slightly. The banks of both V's share the same part of the block and have common cylinder heads. All conrods going to the one crank, each crank pin carrying 2 conrods (one for each V6 engine).
