Meyer Shank Racing has completed their two-car driver lineup for next season. The team confirmed that Felix Rosenqvist will return next season, and his new teammate will be Marcus Armstrong. After two seasons at Ganassi, Armstrong will shift to MSR to take over the No. 66 Honda, vacated by David Malukas. Ganassi is downsizing from five cars to three as the new charter agreement will only allow teams a maximum of three guaranteed entries in each race.

Armstrong finished 14th in the championship this year, which was his first full-time season. He earned four top-fives and four more top-tens, with his first career podium (3rd) at Detroit. Marcus turned heads in his rookie campaign when he finished 11th or better in seven of his 12 starts with Ganassi. Beginning next season, MSR and Ganassi will have a technical alliance and the addition of Armstrong should help both sides. The full press release from today is below.

Meyer Shank Racing (MSR) will add a new face to its 2025 NTT INDYCAR SERIES stable with the addition of Marcus Armstrong who will run the No. 66 MSR entry alongside current MSR driver Felix Rosenqvist.

Coming from a strong open wheel background that includes F4, Formula 3 and Formula 2, Armstrong is now looking to build on his first two seasons of INDYCAR competition as he joins MSR in 2025.

Armstrong was quick to adapt to the INDYCAR series, earning Rookie of the Year in 2023 despite only contesting the road course rounds, taking five top tens in his 12 starts.

The New Zealander added ovals to his INDYCAR calendar in 2024, running the full 17-points paying races this past season, taking three top five finishes including his first INDYCAR podium  in Detroit.

“I’m very proud to be joining Meyer Shank Racing in 2025,” said Armstrong. “I had a great feeling when I met both Mike Shank and Jim Meyer, their passion for performance and meticulous work ethic was obvious from our first conversation and I want to thank them both for this opportunity. I’m looking forward to getting to know everyone at MSR over the off-season with the goal of hitting the ground running at the first race of the season in St Pete.

“This year I got closer to where I want to be performance wise, including oval racing for the first time and I’m looking forward to continuing to push up the order with MSR. We want to be at the front, fighting for wins and I believe we have the recipe to do it.”

MSR, which will be entering its ninth season running in the NTT INDYCAR SERIES, is eager to build on its momentum from the 2024 season which saw the team qualify in the top six, 15 times and finish in the top ten, 10 times. MSR team co-owner, Mike Shank is confident that with the addition of Armstrong for 2025, the team is in a position to produce consistent results next year.

“We’re very excited to welcome Marcus onboard,” said Shank. “He’s really shown a lot of growth and consistency in his first two years in INDYCAR, which is really difficult to do. This series is probably one of the most competitive series out there and he has proven himself to be a real contender. We are going to do everything we can to give him the car and the tools to produce results next year.”

With the 2024 season closing out this past weekend, MSR will begin preparations right away to be ready for the 2025 season opener in St. Petersburg in March.
