Downshift Protection

Downshift Protection is a safety feature in racing cars that prevents a driver from shifting to a lower gear when doing so would cause the engine to exceed its maximum safe RPM limit.

This system works by either electronically or mechanically blocking downshifts that would over-rev the engine. Modern racing cars typically use electronic systems that calculate if the resulting engine speed would be too high and simply reject the gear change request if necessary.

Downshift Protection is especially valuable during intense braking zones, where drivers might be focused on corner entry rather than gear selection. It allows racers to concentrate on braking and racing lines without risking expensive engine damage from an ill-timed downshift. This feature appears in both real-world race cars and realistic racing simulators.
