The engine with the highest mileage ever recorded belonged to an Omnibus bus from Mexico, which traveled an impressive 3.3 million kilometers over ten years on the route between Mexico City and Ciudad Juarez, without needing major repairs. To give you an idea, this distance is equivalent to traveling 87 times around the planet! In 2019, still in perfect working order, the engine was removed and taken to the Volvo Museum in Sweden, where it is now displayed as a symbol of strength and reliability.
