Is it true that new cars should not be driven too fast?

[VonColeman]

New cars should not be driven too fast. A newly purchased car has a break-in period, during which driving at high speeds is not recommended. During this period, excessively high engine RPM can increase the risk of damaging the piston rings. Therefore, manufacturers generally recommend limiting the speed of a new car to between 80~90km/h. Reasons for the break-in period: In the past, due to backward automotive production technology, the dimensions of car parts were not precise and the surfaces were relatively rough. This resulted in the transmission and engine not being able to mesh and operate perfectly after installation and debugging. Hence, the concept of a break-in period was introduced. Definition of the break-in period: The break-in period generally refers to the initial phase where mechanical components come into contact, rub against each other, and gradually fit together. In modern usage, it is often used to describe the period during which two entities or organizational operations become familiar and adapt to each other.
