Uphill racing

I'm not sure if this is true or not, but i had a race with an 2001 eclispe gt and uphill he slightly caught me up to about 120 (he started behind me). Then we raced again on a flat road and i walked him pretty quick. Because rotaries lack torque does that = less speed up hills because of weight? That's my guess.

it doesnt EXACTLY equal less speed up hill. torque is the driving FORCE or a tendency to turn about an axis. going up hill means youre going against gravity instead of going perpendicular to it. which means the torque has more of a force working AGAINST it. in the case of the eclipse it probably had a higher torque to weight ratio than you do. it takes a lot less torque to get a car going and keep it going when there is little opposing forces(ie wind or gravity). u can have a car with 1whp and 23409582354lbs torque go up a hill but a car with 3245943578245whp and only 1lbs of torque not go up a hill at all. drive somewhere with no gravity and there would be no difference going uphill or even downhill.

No, The ammount of power your car is making will dettermine it's acceleration uphill, or on a flat surface. Is it possible you were in a differnt gear for the two runs? or shifted at a differnt point?
