eli5: How do car engines last so long?

1.03K views

A car engine basically has thousands of mini explosions happening inside of it, is has parts moving very fast and generating tons of heat, and experiences extreme temperature fluctuations on a daily basis. Yet it is the part that usually dies last in a car.

How do they make them last so long and why are we unable to make other parts of the car as long lasting, such as tires and brakes?

There have been better longer lasting engine designs that were shelved by the auto industry in favor of cars that break quicker so they can resell more. Toyota is experimenting with new engine types that are a bit closer to the old shelved designs that GM didn’t use.
