What is the redline rpm of the Gordon Murray T.50's V12 engine?

The Gordon Murray T.50’s V12 engine has a redline of 12,100 rpm.

The engine is a 3,994cc naturally aspirated V12 developed by Cosworth for Gordon Murray Automotive. Its exceptional redline reflects lightweight internal components, compact dimensions, and a design focused on rapid engine response rather than turbocharged torque. The engine produces its peak power at about 11,500 rpm, so the redline leaves only a narrow margin above the power peak.

The T.50 was conceived as a spiritual successor to the McLaren F1, whose naturally aspirated BMW V12 helped establish the high-revving supercar tradition. The T.50’s engine is much smaller in displacement than many modern performance engines, but it compensates with high rotational speed and specific power.

A common mix-up is confusing the 12,100-rpm redline with 11,500 rpm, the engine’s published peak-power speed. The track-focused T.50s Niki Lauda uses a related but more highly tuned version, so figures for that car should not automatically be applied to the standard road car.
