    • I actually just watched this on YouTube a few days ago. Chevy made a ton of these promotional videos explaining how their car systems work. There is one on differential steering, transmissions, suspension, hydraulics, etc.

    • Car facts: This is a typical open differential and while this is fine for normal street driving, this is a bad setup for performance driving. What you really want is a limited slip diff which locks the wheels under higher torque loads like performance driving and acts like an open diff at low speeds

    • All wheel drive works based on a Universal Differential. Power all wheels and in theory, can be left with one wheel spinning without traction. A 4 wheel drive used both a front and rear differential. You could get stuck with one front and one back wheel turning without traction.
