Background and career
Jann Alexander Mardenborough ( YAHN men-buh-ruh; born 9 September 1991) is a British professional racing driver. He currently competes in the 2025 GT World Challenge Europe Endurance Cup for HRT Ford Performance. In 2011, he became the third and youngest winner of the GT Academy competition, beating 90,000 entrants to earn a professional racing contract with Nissan. He had no motorsport experience, having played sim racing video games instead. During his career, he has finished on the podium in his class at the 24 Hours of Le Mans, won races and contended for titles in GT3 and junior formula cars, and competed at the highest level in Super GT, Super Formula and the FIA World Endurance Championship. Following his GT Academy win, Mardenborough was rewarded with a drive for Nissan at the Dubai 24 Hour race in 2012, finishing third in class. Subsequently, he competed full-time in the British GT Championship, scoring a race victory and challenging for the title. In 2013, he competed in the European and British Formula 3 championships, before moving to the GP3 Series for 2014 and 2015. He was a race winner in GP3, and also finished second overall in the Toyota Racing Series in 2014. He also competed in the 24 Hours of Le Mans, finishing third in the LMP2 class on his debut in 2013 and helping his team lead the category for 14 hours the following year. He competed for Nissan Motorsports in the top LMP1 class of the 2015 FIA World Endurance Championship, but the team withdrew from the series after one race because of a very uncompetitive car. In 2016, Mardenborough moved to race in Japan, where he competed in the top-level Super GT and Super Formula championships. In the 2016 season, he won a race and was a title contender in the lower GT300 class of Super GT, while also finishing runner-up in the Japanese Formula 3 Championship. In 2017, he moved up to the top GT500 class, where he raced until the end of 2020, scoring a single podium finish and contending for wins on multiple occasions. 2017 was his only season in Super Formula, where he took a pole position. In 2015, Mardenborough was named as one of the 50 most marketable athletes in the world by Sports Pro Media. The 2023 film Gran Turismo is loosely based on his career.
Mardenborough was born in Darlington to English footballer Steve Mardenborough during the three years his father played for Darlington F.C. He spent most of his childhood in Cardiff, Wales. Mardenborough is portrayed by Archie Madekwe in the 2023 racing film Gran Turismo. Mardenborough serves as a co-producer, stunt driver and consultant on the movie, which depicts his early career and personal life. He gave permission for the filmmakers to include his 2015 crash at the Nürburgring Nordschleife, which killed one spectator. He felt it "would have been a disservice for the audience for that not to be in there".
Mardenborough became interested in cars and dreamed of becoming a professional racing driver from the age of five or six, having learnt that it could be a job. He shelved the idea as he got older as his family did not have the money to start a career in motorsport, and he did not know anyone who could sponsor him. He began playing racing video games at the age of eight, when his friend had Gran Turismo on the original PlayStation. He visited to play the game so often he was eventually given the console and game to play at home. Mardenborough played the game almost constantly, including subsequent Gran Turismo titles on the PlayStation 2 and PlayStation 3, later with a force feedback steering wheel and pedals. In 2010, Mardenborough went to university to study motorsport engineering but dropped out after three weeks as it was too maths-based for his liking. During a gap year, he entered an online time trial for the GT Academy competition on Gran Turismo 5, which offered a professional racing contract with Nissan to the overall winner. Among over 90,000 contestants, Mardenborough scored in the top 20 in his region required to qualify for the next stages. He then underwent training and a series of physical and racing challenges, culminating as one of four contenders left for the final - a real-life 20-minute race at the Silverstone National Circuit in Nissan 370Z sports cars. Mardenborough won by eight seconds to be crowned GT Academy winner, and earn the Nissan professional contract. Mardenborough had never driven a high-performance car or been on a racetrack before GT Academy.
Mardenborough took part in the 2011 GT Academy competition, a joint venture between Nissan and "Gran Turismo" developers to identify potential racers via online racing events. Mardenborough won the competition despite having no prior professional racing experience. Following his GT Academy victory, Mardenborough began a driver training programme and competed in several national races, qualifying for an international racing licence. He was rewarded with a drive in a factory-backed Nissan 370Z GT4 at the Dubai 24 Hour race in January 2012. Driving alongside fellow GT Academy winners Lucas Ordóñez, Jordan Tresson and Bryan Heitkotter, he finished third in his class and 26th overall. During the rest of 2012, Mardenborough competed for RJN Motorsport in the British GT Championship with a Nissan GT-R GT3. Together with Alex Buncombe, he won a race at Brands Hatch and ended the season in sixth place in the GT3 championship. The pair had been on course to win the title in the final race until damper issues forced them outside the points. He also took part in four rounds of the Blancpain Endurance Series.
In 2013, Mardenborough switched to formula racing. At the beginning of the year, he contested the 2013 season of the Toyota Racing Series in New Zealand. He was the best-placed rookie and finished the season in tenth place in the championship. After that, he returned to Europe and secured a seat with Carlin Motorsport in the 2013 campaign of the FIA European Formula Three Championship, as well as the British Formula 3 Championship. He scored two podium results and finished sixth overall in the British series, while he was 21st out of 36 drivers in the European championship. In 2014, Mardenborough again competed in New Zealand's Toyota Racing Series at the start of the year, finishing second in the championship, only eight points behind the champion. He then joined Arden International to compete in the 2014 GP3 Series, the third-tier feeder series to Formula One, and was also signed by Red Bull Racing for a driver development programme. He won his first GP3 race in Germany after starting from pole position and setting the fastest lap in the reversed-grid sprint race. An additional podium and seven further points finishes during the season placed him ninth in the overall standings out of 36 competitors, ahead of his two teammates.
Mardenborough made his debut at the 24 Hours of Le Mans in 2013, driving a Zytek Z11SN-Nissan for Greaves Motorsport alongside Lucas Ordóñez and Michael Krumm in the LMP2 class. Throughout a wet/dry race, the crew fought for a podium finish despite losing time due to untimely safety car periods, and ultimately achieved the feat by finishing third in class and ninth overall after a car ahead of them was disqualified post-race. Later during the summer, he took part in the Spa 24 Hours in a Nissan GT-R GT3 together with Wolfgang Reip, Lucas Ordóñez and Peter Pyzera. This full GT Academy lineup claimed third position in the Pro-Am class and seventh overall. Mardenborough returned to Le Mans in 2014 with OAK Racing, whose Ligier-Nissan LMP2 car he shared with Alex Brundle and Mark Shulzhitskiy. The trio led the LMP2 category for 14 hours and were in contention for the win until a spark plug issue with two hours remaining dropped them to fifth in class and ninth overall at the finish. At the 2014 Goodwood Festival of Speed, Mardenborough set the fastest-ever supercar time up the famous "Goodwood Hill" whilst piloting the Nismo Nissan GT-R with the optional 'Time Attack' package. In 2015, Mardenborough was selected as one of the drivers for Nissan Motorsports' entry into the top LMP1 class of the FIA World Endurance Championship (WEC), which includes the 24 Hours of Le Mans. He also continued racing in GP3, switching to Carlin for the 2015 season. Nissan entered the WEC with an unconventional front-engined car, named the GT-R LM Nismo. The team missed the first two races of the season while trying to improve the car, before making their debut at Le Mans. The GT-R LM Nismo proved highly uncompetitive during the race and Mardenborough's No. 23 car broke down terminally with an hour remaining, but he was consistently the quickest of the three drivers in his car. Nissan withdrew from the remainder of the season and eventually cancelled the programme at the end of the year. In GP3, he claimed two podiums and scored points on six occasions to finish ninth overall ahead of future IndyCar champion Álex Palou. He missed four races during the season as he took part in a round of the GP2 Series as a substitute for another driver at Carlin and had a testing commitment at the end of the year. On 28 March 2015, during a one-off outing in the VLN series, his GT3-class Nissan GT-R Nismo caught air at the Flugplatz section of the Nürburgring Nordschleife. It cartwheeled over the fence into spectators. One person was killed and several were injured, while Mardenborough was not seriously injured. Mardenborough's achievements and growing global profile led to Sports Pro Media naming him 50th on their 2015 list of the 50 most marketable athletes in the world.
