Note: The Penske Entertainment editorial staff is looking back at the 10 biggest moments of 2025 in the NTT INDYCAR SERIES in this year-end series, with one installment appearing on the site per day in countdown fashion from Dec. 22-31.

Team management in the NTT INDYCAR SERIES took on a different look in 2025.

Perhaps the highest-profile move was Arrow McLaren naming former driver Tony Kanaan as its team principal. Kanaan became the first former driver to officially receive that title, although many like him have been (and currently are) team owners and decision-makers.

Kanaan made several changes within the papaya organization this year, including the hiring of Kyle Moyer a month after the veteran team manager was released by Team Penske in May. Moyer, who worked with Kanaan in his 2004 championship season at Andretti Global, is now Arrow McLaren’s competition director. Arrow McLaren also hired veteran engineers Eric Cowdin, who won the 2013 Indianapolis 500 with Kanaan, and Olivier Boisson to management positions. On the driving side, 2014 Indy winner Ryan Hunter-Reay figures to be a strong addition to the team’s May lineup.

Jay Frye left his post as INDYCAR president in February, and two months later he was hired to the same position at Rahal Letterman Lanigan Racing. After the season ended, a second former INDYCAR president joined the team: Brian Barnhart, who is now senior vice president of operations. Also now on staff is Gavin Ward, the former Arrow McLaren team principal, and the arrival of these veterans should create additional intrigue with the three-car team co-owned by Bobby Rahal, David Letterman and Mike Lanigan. On the driving side, RLL also added former Formula One driver Mick Schumacher.

Andretti Global signed another former Team Penske executive – Ron Ruzewski – as its team principal. Ruzewski had been Team Penske’s managing director. Ruzewski replaces Rob Edwards, who was elevated to chief performance officer of Andretti Global’s parent company, TWG Motorsports.

As part of the shakeup in May, Team Penske elevated Jonathan Diuguid to the role of Penske Racing president. Diuguid had been leading the company’s global sports car program. Also, Travis Law became the competition director and longtime engineers Dave Faustino and Ben Bretzman moved off the timing stands to take senior roles.

All of the aforementioned teams, plus others, will be chasing Chip Ganassi Racing, which has won the past three and four of the past five season championships with Alex Palou driving the No. 10 Honda. Team owner Chip Ganassi is expected to bring back nearly everyone from his three-car operation.
