McLaren M4B

The McLaren M4B was a Formula One racing car constructed by Trojan for Bruce McLaren Motor Racing and raced five times by New Zealander Bruce McLaren at the start of 1967. The M4B was based on the M4A Formula 2 car as a stopgap between the M2B and the M5A. Additional fuel tanks were added either side of the cockpit to allow the car to run a full Grand Prix distance, and the rear end of the car was cut away to accommodate a 2.0 litre BRM type 56-2 V8, an enlarged and updated version of the engine with which Graham Hill had won the World Championship in 1962.
