The Can Am championship, officially known as the Canadian-American Challenge Cup, existed from 1966 to 1974. The Can-Am era still stands as the penultimate Golden Era of Road Racing, with Group 7 sports racing cars of virtually unrestricted design, resulting in the quickest cars in the world at the time – quicker than any F1 or sportscars running in the World Championship. This unrestricted environment resulted in many technological firsts in motorsports, such as aerodynamics and wings, turbocharged engines, and the use of “exotic” materials such as titanium.
The McLaren M6A, with Bruce McLaren driving, won the Can Am Championship in 1967. This represents the beginning of the dominance of McLaren in the Can Am series for the next 4 years.
The customer version, the M6B became the weapon of choice in 1968; Chassis number #50-07 is one of 17 cars built by McLaren for customers that year. It competed effectively in the series from 1968 to 1972 by three owners. Now, it is actively campaigned by George Frey, in vintage races all over the US and Canada.
