Marcus Armstrong will join Chip Ganassi Racing for road and street course races across the 2023 IndyCar season - teaming up with six-time IndyCar champion and fellow New Zealander Scott Dixon.
Armstrong will drive the No. 11 Honda after switching from the Formula 2 Championship where he drove from 2020 to 2022 and earned four wins and eight podiums.
"I'm ecstatic to be a part of the IndyCar Series, but especially with Chip Ganassi Racing because it is such an iconic and successful team. I have an extraordinary opportunity in front of me to learn from people that have been performing at the absolute highest level in this sport," said Armstrong.
"As a Kiwi, I've always watched Scott Dixon succeed in the championship with this team, so on a personal level this is quite special for me. I am a hard worker that looks to improve every single day. With the knowledge and personnel that this team has, I'm very excited to take on this new challenge."
The team's managing director Mike Hull said Armstrong was an exciting signing.
"As a 22-year-old, what is in common to others who have climbed into IndyCar with CGR is that at that age he already knows how to win.
"That's been repeatedly proven at the highest global level. Besides talent, the intangible that he brings creates measurement through opportunity."
