Arrow McLaren has signed a multi-year extension with Chevrolet, retaining the manufacturer as its IndyCar engine supplier as the championship prepares for a new car in 2028.
The team and Chevrolet did not disclose the agreement's expiry date or financial terms. The announcement nevertheless gives Arrow McLaren continuity through a major development period, with both organisations planning closer engineering collaboration around the Dallara IR-28 chassis.
Extension covers IndyCar's technical transition
IndyCar has begun early validation work for the IR-28, which is scheduled to enter competition in 2028. The platform is expected to introduce revised aerodynamics, a better power-to-weight ratio, new wing configurations and updated safety systems.
Arrow McLaren says early manufacturer involvement will be important as teams integrate the next chassis with the series' engine and hybrid systems. Retaining Chevrolet avoids an engine-manufacturer change while that work develops and keeps the existing engineering relationship in place for the transition.
McLaren entered IndyCar full-time in 2020 through its partnership with Schmidt Peterson Motorsports, initially competing as Arrow McLaren SP. Chevrolet has powered the operation throughout that period.
According to McLaren's announcement, the partnership has produced 14 wins, 54 podium finishes and 13 pole positions across seven seasons. Those figures are the team's published account of the programme and were not accompanied by a race-by-race audit in the release.
Technical continuity supports the 2027 line-up
The extension arrives before Arrow McLaren fields its 2027 driver line-up of Pato O'Ward, Scott Dixon and Felix Rosenqvist. It gives the three-car programme a confirmed engine relationship while the team targets the IndyCar championship and Indianapolis 500.
Team principal Tony Kanaan said the longer agreement would increase stability and allow Arrow McLaren and Chevrolet engineers to collaborate more closely during the technical change. General Motors competition vice president Eric Warren described performance development for the next-generation car and powertrain as a shared priority. MRI has paraphrased those statements rather than reproducing the release's quotations.
The announcement does not specify whether Chevrolet will change the commercial or technical support supplied to Arrow McLaren, nor does it publish testing allocations, staffing plans or performance targets for the IR-28 programme.
For suppliers and prospective partners, the material development is a long-term manufacturer commitment behind one of IndyCar's largest teams. The agreement fixes a central part of Arrow McLaren's technical package before the 2027 season and reduces uncertainty ahead of the following year's chassis change.
