eli5: How do car engines last so long?

937 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 are brakes that will last potentially the life of the car. At least when it comes to brake rotors. However, carbon ceramic rotors cost something like $3,000 -$15,000
