McLaren's first racing car designed and built "from the rubber up" by Bruce McLaren Motor Racing was the M1. The car with a small block Oldsmobile had immediate success driven by Bruce McLaren. The car was raced in North America and Europe in 1964 in various A sports and United States Road Racing Championship events. In 1965 the team car was the M1A prototype from which the production Elva M1As were based. In late 1965, the M1B (also known as Mk2) was the team car for the North American races at the end of the year. For the Can-Am Series, which started in 1966, McLaren created the M3 which Bruce and Chris Amon drove – customer cars also appeared in several races in the 1966 season. With the M3, they led two races but scored no wins, and the inaugural title was taken by John Surtees in a Lola T70. The following year, Robin Herd purpose-designed the Chevrolet V8-powered M6A, delays with the Formula One programme allowing the team to spend extra resources on developing the Can-Am car which was the first to be painted in McLaren orange. With Denny Hulme now partnering Bruce, they won five of six races and Bruce won the championship, setting the pattern for the next four years. In the 1968 season, they used a new car, the M8, to win four races; non-works McLarens took the other two, but this time Hulme was victorious overall. In the 1969 season, McLaren domination became total as they won all 11 races with the M8B; Hulme won five, and Bruce won six and the Drivers' Championship. From 1969 onwards, McLaren M12 – the customer "variant" of the M8 – was driven by several entrants, including a version modified by Jim Hall of Chaparral fame. McLaren's success in Can-Am brought with it financial rewards, both prize money and money from selling cars to other teams, that helped to support the team and fund the nascent and relatively poor-paying Formula One programme.
