Cadillac Confirms Active Development of 2026 Power Unit

Cadillac is actively developing its Formula 1 power unit under the incoming 2026 regulations, choosing not to wait for a potential return to V8 engines. Mario Andretti confirmed that work is already well underway, ensuring the American manufacturer will be prepared with a compliant engine upon its official entry.

Why it matters:

There has been significant speculation regarding the future of F1 power units, with some figures like FIA president Mohammed Ben Sulayem pushing for a V8 return as early as 2029. By proceeding with the current regulation engine, Cadillac demonstrates a commitment to its F1 project regardless of potential rule volatility, aiming to establish itself as a competitive works team rather than a bystander waiting for regulatory shifts.

The details:

• Active Development: Contrary to whispers that Cadillac might delay its engine program to align with a V8 switch, Andretti confirmed the team is fully focused on the new regulations. "They've been working on it, no question," Andretti stated, expressing high confidence in the team's readiness.
• Timeline Uncertainty: While development is active, the specific season for the engine's debut remains fluid. Discussions point toward 2028 or 2029, though Andretti noted these dates could change based on contracts and technical progress.
• Immediate Plans: Cadillac will make its debut this season utilizing customer Ferrari power units for drivers Valtteri Bottas and Sergio Perez. While the Ferrari engine is reportedly not as powerful as the Mercedes unit, the team is focused on establishing its footing before switching to its own power.

Looking ahead:

The immediate priority is a successful debut with Ferrari power, but the long-term strategy is clear. Cadillac aims to transition to its own power unit once the project matures, positioning itself as a fully competitive American constructor on the grid by the end of the decade.
