Redline
The maximum safe engine speed, indicated by a red zone on the tachometer.
Redline represents the engine's mechanical limits—the point where internal stresses, valve float, or lubrication breakdown occur. High-revving engines (9,000+ RPM) require lightweight internals, strong valve springs, and sophisticated oiling systems. The Gordon Murray T.50's 12,100 RPM redline is among the highest ever for a road car V12.
