The 15-year old from Bromley had travelled to the championship’s finale at PFi, with one hand already on the trophy and after a solid performance in qualifying, he only needed to finish the two finals to seal the title.
In timed qualifying, McCarthy posted the 3rd-fastest time and went on to take a brace of 4th-place finishes in the preliminary heats. With his Strawberry Racing team-mate, Tom Gamble, taking pole position for the first final, Jack coolly stayed out of the fray to bring his kart home in 12th position.
Now, with an unassailable points lead, the champion-elect chose to drive around in the second final at the tail of the field, watching Gamble complete his second lights-to-flag triumph. Scoring 44 points for his eventual 18th-place finish, Jack knew he was the 2015 champion as he took the chequered flag with his arms aloft.
Asked if he had been nervous before the two finals, Jack said: “I was pretty confident. I had a big points-lead but still had to do my best, and make sure my closest rivals couldn’t catch me. My plan was not to get into any trouble and it was quite boring driving at the back but I’d rather that, than crash and lose the title.”
With some international races still to compete in, including the world finals at Portimao, Portugal in November (8-14), Jack will stay in karts for another year before graduating to single-seaters in 2017.
“My next step will be to move up to Senior Max next season, followed by the MSA Formula the year after. Ultimately, I’d love to be in Formula One or the World Endurance Championship.”
