Ever wonder how your car's wheels can spin at different speeds when you turn, or how it maintains traction on slippery surfaces? This documentary demystifies the incredible engineering behind the differential gear. You'll understand the core mechanics of open differentials and discover how advanced systems enhance performance and control.
