For the most part, most quality motors are within a similar range of torque and RPM capability with some edging out the rest. The electronics driving them will likely make the biggest difference between them and you will only see such differences when one is in it's optimum range. What is the optimum range? Well, that varies. Some are better in the lower ranges, some in the mid and some in the higher ranges. The ones that are better in the higher ranges will be most noticeable visually because you can physically see certain cars begin to pull away slightly from the midway point of the straight. Those that are better in the low to mid range will be similarly identified when approaching jumps with little run up, as they will be able to hit and land jumps better than others without the need for a long approach.

The only way we can alter FDR is via changing the Spur/Pinion combo and that will change the strains placed on motors.
