Force at the wheels (as opposed to torque) is probably the better parameter to graph anyway, as it directly relates to acceleration...
I agree. The OP may consider converting wheel torque to lb's horizontal acceleration by dividing out the wheel radius and then divide out the car's weight to get acceleration. Once you account for weight then you are really calculating acceleration (not wheel torque) so might as well call it that?
