For the 1967 Formula One season the Climax-engined chassis 101 was sold to Canadian driver Al Pease, and all AAR chassis ran as Eagle-Weslake machines. The season proved to be intensely frustrating for all concerned. Although Gurney and sometime teammate Bruce McLaren managed to qualify the Eagle-Weslake cars in the front two rows of the grid on no fewer than eleven occasions from the season's eleven Grands Prix, only two cars finished a race. That both of these finishes were in podium positions highlights the raw speed of the Eagle Mk1. AAR's first major race win came in the 1967 Race of Champions at Brands Hatch, with Gurney taking the aluminium-chassis 102 to victory in this prestigious non-Championship season opener. 104 was introduced at Zandvoort, the Netherlands, early in ; the lightest and fastest of the Eagle Mk1 vehicles, it was with this car that Gurney scored the team's only Championship victory: the 1967 Belgian Grand Prix.
