LOL, JK, maybe not but I never heard of that one. ANYWHO, I thought from the context of the post that it was clear I was talking about *passive rotating masses* and not every possible factor that goes into a car making power. You may be correct about acceleration and handling may being the same from a physics defintion (not sure, I have to think about it and get back to you) but I think 99% of the peeps here understand it the way I meant it. Acceleration as in how fast you go in a straight line, handling as in making a bunch of turns like in auto-cross or on a track.
