Is it normal for the Audi A6 tachometer 678 to be red?
1 Answers
Audi A6 tachometer 678 being red is normal, indicating the RPM limit. Introduction to RPM limit: First, the power of a car comes from the engine, so there is definitely an RPM limit. Most of the time, the engine operates within a safe RPM range, also known as the rated RPM. Occasionally, stepping on the accelerator might reach the maximum RPM, or accidentally pressing too hard might hit the limit RPM. However, once the limit RPM is exceeded, it means surpassing the engine's power limit, and the vehicle may choose to issue a warning or cut off fuel supply. Occasionally reaching the redline is not a big issue: Generally, it won't cause engine seizure. But if the vehicle is consistently operated at maximum RPM or even limit RPM, inadequate internal cooling and overloaded transmission components may lead to smoking or engine seizure.
