The McLaren M21 is one of the Mclaren entries the open record knows by name, and by little else. That is not nothing: a name in the catalogue is where a car's story starts to be recoverable.
Where it sits
Its Mclaren stablemates include the McLaren M15 and the McLaren M16.
The record
The open record for the McLaren M21 carries no verified engine, output, weight or price yet. MotorJury does not fill gaps with guesses; this entry gives the model a home in the catalogue and grows as sourced specifications and photographs arrive. Corrections: corrections@motorjury.com.
