What's the one single car part you don't understand on your car?

For me it has to be the helical differential. Absolutely no idea. :O

It burns them.
CO + O2 —-> CO2
So you get lower CO-value
Diesel engines have problem with black smoke. This is unburned fuel. It gets burned, too.

Some weird magnet in the engine bay, it’s meant to do something with the timing, but I doubt it works, the designer was fired after they made this car, so I guess it didn’t work, also they worked with this guy for about a decade or so, it was one of their touring car drivers

Why diffs make one wheel turn one way when you turn the other wheel the other way… yet they both drive forward…
