Oh, as the thread is talking about racing two cars side by side, I'm thinking 0-400m type of competition instead of 0-60miles competition. You're right if it's time to speed type of competition, haha

[B]Comon guys, torque is a dynamic thing.

 

I don't think either theory is correct. Compare any Diesel to an S2000. The Diesel is going to have a much higher torque to weight ratio than the S2000, but it ain't going to perform worth a crap on flat ground.

If you raced an S2000 against a diesel on level ground, the S2000 would 'probably' eat the diesel's lunch. If you race the same 2 cars on a 40 degree incline (with good traction), I don't think the S2000 will ever even be able to move (forward), but the diesel will probably cruise right on up the hill.

 

Well if you change one variable (the incline) in an equation, you have to understand how it affects all the other variables.

For instance, which car gets a better launch off the line when going up a hill? This will probably make more of a difference than anything else. Has to do with gearing and which wheels are being driven (weight distribution).

Comparing a peak torque value on two cars is meaningless.

I see that everyone who replied here all already have good understanding...

 

Net thrust to weight. Nothing else matters if you're computing non-traction limited max accelerations.

How much force is pushing you forward? How much is pushing you back? How much weight is that force pushing?

Discussing anything less introduces far too many "if/but/then"s.

lol wow.. lot of technical answers. i think the basic point was, will car A ALWAYS beat car B OR.. will there be circumstances where car B having more torque ever beat car A. seeing from your responses, i see theory 1 is out the window.
