There are some very significant differences that separate the Class 2 experience for the player as they move up in the season. The vehicle size has grown, it would appear similar onscreen to keep the visual experience consistent but the Class 2 racers are about 50% bigger than the Class 1 racers. The larger size will connote a more powerful machine that will behave similarly but is capable of much greater speed and even special maneuvers. The Class 2 will race over deserts, coastal areas, and possibly the lower atmosphere. The wings on this vehicle pivot allowing it perform tight turns at speed. The rear flaps also would help move the craft. Another big difference is the pilot in now fully enclosed as you can see in the rendering below.
