Everything you’ve ever wanted to know about how IndyCar racing works behind the scenes is about to be revealed to you. Get excited.

Our tame auto engineer David Tracy and mad scientist Jason Torchinsky are at the Indy 500, and they visited garage to learn as much as they could about how these cars work: engines, gearboxes, aero, the difference between Chevy and Honda cars, how that bonkers steering wheel works, and much more.

Check out our live (well, not so live, it already happened but it’s great) tour of the garage below. Much more to come this weekend from America’s greatest race.
