Second question first. The answer is no.
First question second. Snoope, there is no "rule". There are too many variables such as type of transmission (auto or manual), drivetrain layout, etc. You can take two measurements on the same car with the same engine and transmission but a different differential and get different results. How efficient is this particular component, what type of lubricants are being used, etc, etc, etc, (hey Ma look at me I'm Yul Brenner).
So.... if you can get 90% efficiency your doing damn good. Most cars will be closer to 75-80%.
Snoope, I got a question for you. I really enjoy answering most of your posts, but where the hell do you come up with this stuff? See ya.
