Bugatti Veyron 16.4

[YellowMaranello]

Just knowing what it is and what it has makes it pretty enough, although I agree with Chris on its looks.

the engines concept is explained by an animation on the bugatti s.a.s. - website.
http://www.bugatti-cars.de
it can be found under models>veyron>engineering>engine>stories from 1001 ps.
sorry, can not add the link directly, the site requieres flash6

In that video they show them taking two v-8's, putting them side by side and combing the crankshaft and just altering the inside cylinders to not touch each other. As I was watching that I thought it'd be really hard to keep it from overheating with the cylinders that close, but I guess with a company like Bugatti, they took care of it. Thanks for sharing that site with us, very interesting to watch the videos. :ylsuper

you are right. the engine concept requires a well calculated cooling circuit. in the end 90's bugatti developed a 18-cylinder engine based on three 6-cylinder engines.
these three cylinder banks were arranged about 60° (don't know the value exactly) around the crankshaft. therefore the cylinders were that way close at eachother that
some thermodynamical problems occured. so the engine never hit the production line.

not only heat, but keeping the engine balanced is difficult.

It would be intersting to know the firing order of the cylinders, if say they basically were two v-8's, would 2 cylinders not fire at the same time then? just crossed my mind i guess

Sure would be fun trying to find the spark plug that failed.

Actually, Volkswagen developed the "W18" from six three-cylinder engines. I believe you are correct on the bank angle. It was odd to look at because from above (in the engine bay), it just looked like a V12, but there was that third bank below which wasn't initially obvious. When the engine is displayed, it looks odd with it's V12 plus six.

Does anyone know anymore specs on the engine, say like compression, boost from the turbo, bore/stroke. It'd be interesting to see how much power it'd make without the turbos. I'd guess around 500 or so but i dont know.
