1966 was Hulme's first full season of Formula One. Now, after the departure of Dan Gurney, he was the outright number two at the Brabham team behind Jack himself. Finishing a fine fourth that year (with Jack winning the Drivers' and the Brabham team the Constructors' Championship), the highlights came with a third place at Reims in France, a second behind Brabham at Brands Hatch, and the fastest lap at Zandvoort, before ignition problems put paid to his race there. Whilst his boss won the World title, Hulme made it to the podium four times during season, finishing fourth overall in the standings.
