I tried posting this in the main forum, but got no bites. So Ill try it here. quick question about gear ratios. First, I understand teh premise of the mechanical advantage, I am just not sure how to get the physics class to the driveway. I am looking at a new car that offers both a 5 speed manual as well as a 5 speed automatic. I have the gear ratios of the two respective trannys. 5MT 5AT Sport 3.307 3.620 1.842 1.925 1.310 1.285 0.970 0.933 0.755 0.692 My question is this... what is the 'real world' comparison of the two? I understand that for each respective gear, one would be quicker, with lower top end, and the other would be slower, but with a greater top end... what I dont know is which is which. Obviously, I havent driven the car yet... doing my homework first. Anyone have any ideas?
