Arrow McLaren IndyCar Team has signed a multi-year engine extension with Chevrolet, locking continuity for 2027 amid looming technical changes across the championship.

The agreement underpins preparations for Dallara IR-28 testing through 2027 and its 2028 debut, ensuring early integration between chassis and Chevrolet power unit.

IR-28 targets closer racing and improved safety via revised aerodynamics, better power-to-weight efficiency, innovative wings that aid following, and strengthened protection structures.

Early manufacturer–team alignment is decisive, streamlining simulation correlation, dyno programmes, and on‑track development under the forthcoming regulations.

Zak Brown cites seven seasons of technical collaboration with Chevrolet and sustained backing from General Motors leadership as foundations for race-winning competitiveness.

Since 2020, Arrow McLaren has logged 14 wins, 54 podiums, and 13 poles with Chevrolet power, reflecting consistent performance across varied circuits.

Those returns underpinned Chevrolet’s manufacturers’ titles from 2022 to 2024 and contribute to its 13 Indianapolis 500 victories in the event’s history.

Reliability has been a differentiator. In 2026, Arrow McLaren led Chevrolet entries in 11 of 18 races by best finisher.

Christian Lundgaard completed every lap that season, while teammate Pato O’Ward missed only one, underscoring operational discipline and mechanical robustness.

Team principal Tony Kanaan describes the Chevrolet relationship as the strongest yet, enabling deeper engineering integration ahead of the 2028 chassis regulation shift.

The 2027 lineup blends experience and speed. Pato O’Ward joins forces with Scott Dixon and Felix Rosenqvist to strengthen coverage across ovals, streets, and road courses.

General Motors’ Eric Warren frames the renewal as strategic, arguing that unified development will decide execution as new car and powertrain technology phase in.

Rival manufacturers are reorganising too. A recent Honda team leadership update signals sharpened focus as the grid readies for the IR-28 era.

Performance in 2027–2028 will hinge on traffic efficiency, drivability, strategy execution, and bulletproof reliability over dense calendars and mixed venue demands.

With stability secured, Arrow McLaren and Chevrolet approach the next cycle with aligned objectives and a framework designed to absorb regulation-driven disruption.
