M2B - 1966
This was McLaren Racing's first Formula 1 car. Technically it was a spectacular success, for the chassis was the stiffest open cockpit unit ever built, with torsional rigidity approaching 10,000lbs/ft per degree. The 1966 season was the first to be run under the 3-litre Formula 1 rules, however the McLaren car was not a success and was shelved at the end of the year. Two chassis were built, but only one raced.
