Differential

A differential compensates for the difference in wheel speeds on the driven axle. When your car is cornering, the wheels on the driven axle turn at different speeds - the wheel on the inside of the bend has a shorter distance to cover than the wheel on the outside - causing the outside wheel to turn faster. Compensating for this difference in speeds is generally the task of a bevel differential. An electronic locking differential (EDL) prevents either wheel from spinning freely, directing the power to the wheel with better grip instead.
