What is the red light on the tachometer for in the Mini Cooper?

The red light on the tachometer in a Mini Cooper serves as a warning indicator for the engine's RPM (revolutions per minute). It typically signals that the engine is approaching or has exceeded its maximum safe RPM threshold, which can lead to engine damage if not addressed. When this light illuminates, it is advisable to shift to a higher gear or reduce throttle to avoid potential harm to the engine.
