Many LEGO Technic kits contain a differential gear but no engine. It looks cool. But you can see the power of that gear only in an actual motorized vehicle. In this LEGO MINDSTORMS Robot Inventor Hot Rod, you can easily replace the differential gear with the 28 tooth gear. Check this video to see the difference in turning performance.
