well i have the sauber c9 history book and they explained the c291's engine. its 2 straight 6's horizontally opposed but on 2 separate crank shafts so the are individually attached to the transmission and thats why they were having reliability issues. It would me it a flat 12 if it was on the same crank but its separate cranks. The bell housing must have been huge!!
I love flat 12 engines

That almost sounds like the 4 rotor 2.6L 787B race car

Yeah, even modern day Zondas sound like it, due to having a Mercedes-Benz V12. Very cool sounding.

That C291 was one sweet looking car. I do prefer the engine noise of the C9/C11's though.

How do get a 180 degree V12? surely that would make it a flat 12?
barnywal 3 years ago
I think that a "flat engine" form and the "180 degree V12" form are different.

I don't think have been any geuine Flat-12s. Almost all of them, like the Porsche 917's, are just 180* V12s.

Ferrari Boxer is a Flat-12 isn't it. please correct if wrong,
bentleyv8t 2 years ago
No, that's just a 180 degree V12. A flat engine has split crankpins, whereas a V engine has shared ones. Ferrari just flattened their V12.

HAHA! A Porsche 917 is a Flat-12!
