Marcus Armstrong announced his arrival to the NTT INDYCAR SERIES in full effect in 2023, winning the Rookie of the Year title despite racing exclusively in road and street course races.

Armstrong completed 97% of his available laps (1,140 of 1,175) across his rookie campaign, finishing in the top-10 in five of his 13 starts. Armstrong achieved a season-high P7 result on the challenging Toronto street circuit.

The Christchurch, New Zealand, native will expand his driving duties in 2024 after signing a multi-year contract with Chip Ganassi Racing. Armstrong piloted an INDYCAR on an oval for the first time at Texas Motor Speedway on September 13, as he primes to embark on the upcoming full season schedule.

Armstrong made his North American professional debut after competing in the FIA Formula 2 Championship from 2020 to 2022 where he earned four wins and eight podiums. Armstrong scored his first victory in the series in 2021 at Jeddah Corniche Circuit in Saudi Arabia, and then registered three wins across the 2022 campaign in Italy, Austria and the Netherlands. Armstrong also served as a development driver for the Scuderia Ferrari F1 team in 2021.

The Kiwi launched his racing career behind the wheel of go-karts at 10 years old. He won five go-karting national championships in New Zealand before moving to Europe in 2015 to compete on the world stage. In 2017, Armstrong made the jump to Formula 4 where he won the Italian Formula 4 championship in his first season competing in the series. Armstrong competed in Formula 3 across the 2018 and 2019 seasons, where he tallied four wins, four pole positions and 16 podiums.
