Most wheeled vehicles around the world are using some form of differential. Whereas use of a solid axle does not allow the two wheels to rotate at different speeds, which causes problems while turning. When cornering, the vehicles outside wheels travel further in the same time period as the inside; and if an outside wheel is not allowed to travel faster, wheel slippage is unavoidable. A solid axle however, is beneficial because it provides power to both wheels at all times. This was a distinct concern with the '09 model of the SAE Baja vehicle. The focus of the project was to provide a solution to this issue. A gearless differential was selected as a solution to provide differentiation between the wheels while limiting slip during acceleration giving some of the benefits of a solid axle.
