Just to be sure I do not
Just to be sure I do not misrepresent here, that 3-5 years is MY total outlook based on what I understood the situation was leaning. The hard 3 year figure, though, would likely be a minimum for ANY OEM to get a new engine in place for high-volume production; but that was a number I did hear and one that Scuderi would agree.
Keep in mind, though, the 3 year clock does not count until the ink is dry on a bonafide contract. So your guess is as good as mine on that part. That's why I added the additional 2 years making it a 3-5 outlook; in other words, in an absolute sense. If the engine was used for a generator engine, that could fly first, in my opinion.
For the record, I have no reason to doubt that 3 year min timeline. Fact is, any OEM would need time to design, package, test, validate, redesign, tweak, meet EPA for certification, etc. Certifying a new engine is not a walk in the park.
