Watch the NASCAR Championship Race this Sunday live on NBC at 3 pm ET!

NASCAR is a uniquely American motorsport. It has always been about testing team and driver performance on as equal footing as possible. In this Science Garage, we took a field trip to Texas Motor Speedway for a behind the scenes look at the Science of Stock Cars. Bubba Wallace Jr let us know how the new rules feel on the track, and Parker Kligerman walks us around his car and tells us about all the little things teams do to get an edge in the race. It’s about aerodynamics, it’s about downforce and drag, and it’s about playing by the rules, while searching for the loopholes. NASCAR RULES!

Bart teaches us how cars work buy blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

      And here I was thinking NASCAR was just cars going around in a circle. Interesting!

      No, seriously, I did.

      NASCAR is the misunderstood brother of motorsport. Gotta love the F1 kids talking shit about this series like they ever drove a race car, NASCAR is much more complex than "just driving circles & turn left", it's the science of doing that well

      If the rules are so hell bent on keeping everything so equal, why isn’t every driver just issued the exact same car from a common manufacturer? That’s not a Camry, and that’s not a Mustang... so why even play like it is. Just issue each driver an identical car.

      Rules: the reason drag racing and road racing are both better than NASCAR, aka driving in a circle over and over

      Hate the BS rules. 550 when it should be 900. Who cares if they want the slower to be in the mix. Get better at driving.

      raceing is about 2 things a good driver and superior enineering...
      half of the rules ruin the engineering part
      besides that these stupid restrictor plates started the downfall of nascar raceing

      This is why nascar is boring. It’s basically 200 mph traffic. F1 seemed to deal with faster and more technology advanced cars just fine. And they take lots of lefts and rights. Or any racing in Europe.
