ToronadoI was set to say the Mercedes SL 55 AMG but then I bought a Mercedes SL 600 (R129) and put semi racing muffler on it. It makes it sound like a true V12, A.K.A. a low displacement high revving Ferrari 12 cylinder, like a Testarossa's or a 575's
ampsarusIf you are refering to the Testarosas from the 80's, they were flat 12's.![]()
Would that be like a Boxer engine, like in Porches and Subarus?Grand PrixHowever, they were not horizontally opposed 12s. They were really just powered by a 180 degrees V12. A true horizontally opposed engine would have cylinders on both sides aligned with each other, hence, the name. All horizontally opposed engines are flat, but not all flat engines are horizontally opposed.
Sorry to be a nit-pick.Just making sure that everyone knew that tidbit. 👍

ampsarusI don't understand- If there are 2 banks 180 degrees apart, isn't it an H-12?
Looks like an H-12...![]()

ampsarusI'm not sure if I'm reading your diagram correctly, but thanks for taking the time to explain.
I infer that this engine's banks are somewhat offset, whereas the boxer's bores are on-axis? How can that be?
A horozontally opposed engine is like this, where the "0" is the crank and the ":::::::" are the bores:
:::::::0:::::::
The boxer motor's configuration is refered to as H- motors. Like my Subaru is a H-4, not to be confused with an I-4, and the 911 is a H-6, not to be confused with a V-6. Am I missing something?![]()
