In drag racing, the main focuses are: speed, speed and more speed. Drag races are determined by which vehicle can drive down a straight road and reach the finish line the fastest. What seems like a simple feat can be quite challenging, as the torque and acceleration of these vehicles, in combination with their elongated pencil shape, makes it difficult to keep the wheel perfectly straight.
Off-Road Racing is different from drag car racing in a number of ways. First of all, there is no paved road for the tires to smoothly ride across, which means that a suspension upgrade of some type is required. Second, off-road vehicles are naturally heavier (because of suspension, tires etc.) and not nearly as fast as drag racers. Lastly, off-road courses usually have obstacles such as bumps, jumps and more to add more of an extreme-sport element to the race.
