Not in fact because it didn't go when I sent it for some strange reason - I sent this when there were no other answers or replies as a tongue in cheek jokey response however when I shut down yesterday it told me that there was 1 item to post so I told it to send it and here it is a day late as you said but unintended.

The Hispano-Suiza J-12 model was powered by a V-12 and unlike the ones you mention, Hispano's aircraft 12 cylinder motors were also in a V configuration. Maybe you were thinking of the current Wartsila-Sulzer? http://people.bath.ac.uk/ccsshb/12cyl/ Tom K. |

Other advantages are cost and simplicity of layout. You can have those 6 nicely-balanced cylinders with only one cam drive, one set of camshafts, etc. Inlines are nice for the layout simplicity of all the intake on one side, all exhaust on the other side. The I6 is a great compromise because of it's inherent balance, and going any longer gets to be "too long" for mechanical-strength and packaging considerations (although longer inlines do exist in some huge-motor applications like mining equipment and ships). For these reasons, the I6 is extremely popular in earth-moving and farming equipment, and in "semi" truck engines. The I6 would be a lot more popular in cars were not for it's length, which makes it impractical to turn sideways for FWD applications. |

Ironically, fitting a long motor transversely may be easier with motorcycles than with cars. With motorcycles, there is no "hard limit" to how wide the motor can be. With cars, there's the shocks and wheel-wells there. Additionally, motorcycles are designed with the clutch and transmission completely behind the motor. With cars, the clutch and transmission are inline with the crankshaft, which is most efficient. |

I drove a white '92 Alfa 33 QV for several years while working in Holland and enjoyed the car quite a lot. I had none of the infamous Alfa probems over a span of about 3.5 years. |
