GT Academy Launches Racing Career
In 2011, Mardenborough won the Nissan‑PlayStation GT Academy competition, beating over 90,000 gamers to earn a professional racing contract with Nissan. This prize gave him factory support and funding to begin a real racing career. In 2012 he raced a Nissan GT‑R GT3 in the British GT Championship; that year he won a race at Brands Hatch and finished sixth in the GT3 standings. He also finished third in class at the 2012 Dubai 24 Hours (driving a Nissan 370Z). These results earned him prize money and racing salaries as a factory-supported driver.

In 2014 he continued in Formula 3 and GP3; he won his first GP3 race in Germany from pole. In 2016 he moved to Japan for Super GT and Japanese Formula 3. That year he won the GT300 class race at Fuji Speedway and scored additional podiums. He also claimed four wins and finished runner‑up in the 2016 Japanese Formula 3 Championship.

These partnerships (car manufacturers, racing teams and brands) provided sponsorship income and endorsements beyond his race winnings.
