Andretti Global has assigned its crew chiefs and race engineers for the 2026 IndyCar Series season.
On the driver front, two-thirds of the team’s 2025 full-time roster carries over with Kyle Kirkwood, who placed fourth in the championship in the No. 27 Honda, and Marcus Ericsson, who took 20th in the No. 28 Honda. In the No.26 entry, which the Formula 2-bound Colton Herta steered to seventh, Will Power takes the controls after leading Team Penske with ninth in the standings last season in the No. 12 Chevy.
Continuity among crew chiefs has been maintained for all three cars.
“Nick Allen’s going to continue on the 26, Scott Marks will continue on the 27, and Neil Campbell will continue on 28,”
The most significant change comes with the confirmation that Power will work with Andretti veteran Andy Listes as his race engineer. Listes replaces Nathan O’Rourke, who engineered Herta for 115 of his 116 IndyCar races – all but his first – and produced nine wins and 16 poles with the Californian.
As RACER revealed in September, O’Rourke had sought to transition from traveling as a race engineer to a shop-based engineering role for more than a year, and has been elevated to an unspecified position within Andretti’s expansive engineering corps, while Listes has been brought back to the IndyCar program after steering Dennis Hauger to the 2025 Indy NXT title with Andretti.
“Andy is awesome and (I’m) super happy that he has agreed to do that,” Edwards said. “He won the (NXT) championship this last season with Dennis, but on the back of that, we had the opportunity for him to work with Will so he’s going to race engineer for Mr. Power.
“Andy was one of our engineers at Meyer Shank when we had the technical alliance there; he worked with Jack Harvey, and then he came back into the family, per se, and engineered Jamie Chadwick in NXT and then Dennis. We’re excited for what we believe this combination of Will and Andy can produce. And Jeremy Milless will be back with Kyle on the 27 car.”
Ericsson will have a new race engineer to partner with in 2026, as Andretti IndyCar and NXT veteran Ron Barhorst steps onto the timing stand. The Swede enters the last year of his contract with the team after completing two disappointing seasons with Olivier Boisson and Dave Seyffert.
“We obviously had to pivot a bit when Nathan (O’Rourke) decided he wanted to step back from race engineering, but it’s great to have talented people already in-house to go,”
“And part of my commitment to him was that there would be IndyCar opportunities in the future. So, happy that we were able to fulfill that for Ron. And we’re excited that Andy and Ron, who are both long-term employees and have grown up in the in the team, are part of what we’re doing for the race engineering group going forward in 2026.”
