I leave burn marks behind both of my rear tires... oh wait, we're talking about the Cobalt


On an open differential, the torque goes to both wheels. When one wheel has less traction (like if it's on snow, ice, water, algae, etc), it'll be the one that spins.

On a limited slip differential, the torque goes to both wheels. When one wheel has less traction, the torque is sent to the opposite wheel with the most traction. So like if the right wheel starts to spin, then the torque will be sent to the left wheel that still has traction. This is achieved through the use of clutch packs and/or gearing. The LSD in the G85 package uses gearing.

On a locked differential, the torque goes to both wheels. When one wheel has less traction, it may or may not spin, depending on the traction that the other tire has. On a locked differential, both wheels are locked together as far as rotation (for better or worse... worse being when you need to take a turn for instance).
