Do vehicles sold and driven in Germany have more power output (horsepower, etc) than the ones sold in the USA?

In principle, yes. Horsepower is linear scale. In practice, however, the amount of drag and weight you'd get from 10 smaller engines might be greater than for a single engine so things might not scale up exactly.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
