IndyCar’s leadership is finally doing what it should have done years ago: securing its engine suppliers before the house caught fire.
Penske Entertainment has agreed to terms with Chevrolet and Honda to remain as engine suppliers beyond 2026, ending a cloud of speculation that never should have existed in the first place. For years, the series drifted in uncertainty while fans, teams, and manufacturers waited for clarity. That indecision wasn’t harmless — it was destabilizing.
This is a premier American open-wheel championship running on just two engine suppliers. Letting doubt linger about whether either would stick around was a dangerous gamble. Had one walked, the series would have faced a credibility crisis and a potential competitive collapse. Instead of projecting strength, IndyCar looked exposed.

The agreement keeps Chevrolet and Honda supplying their 2.2-liter twin-turbo hybrid V6 engines through 2027 — a gap year created when the long-promised new chassis and engine formula were delayed. That deferral pushed the debut of the 2.4-liter twin-turbo hybrid V6 engines and Dallara’s new IR28 chassis to 2028.
That delay matters. Pushing back a major technical overhaul disrupts development cycles, strains supplier resources, and tests patience across the paddock. It’s the kind of decision that may look manageable in a boardroom but ripples through teams fighting for survival.
Now, with 2028 engine regulations effectively locked in, Chevrolet — via Ilmor Engineering — and Honda — through Honda Racing Corporation U.S. — can finalize their 2.4-liter programs and begin preparing engines for IR28 testing later this year. Stability is coming, but only after unnecessary turbulence.
There’s also a strategic twist: Penske is granting each manufacturer a charter, allowing them to field single-car factory efforts. That move mirrors the 25 charters issued to full-time teams ahead of 2025 and signals a deeper integration of manufacturers into the series’ long-term structure.
Let’s be clear — this isn’t a victory lap. It’s damage control that should have been handled sooner. IndyCar survived its engine uncertainty, but it came far too close to flirting with avoidable chaos. The contracts may not grab headlines, but they represent something more important: the series was forced to confront its own instability and lock down the foundation before it cracked.
