When you’re done with this quiz, you’re going to listen to the hum of that engine in that car of yours with a whole new kind of awe and respect.

And let’s be honest, truly knowing the facts about what lies under the hood is important.

The energy that is released from an engine is enough to propel a potato 500 feet. And, that potato might just hurt someone...just saying.
