Power Unit Supply Chain

5 manufacturers build every engine on the 2026 grid. Some supply a single team; Mercedes powers nearly half the field. The PU supply map defines the competitive landscape.

Economics of Engine Supply

The business of building and selling F1 power units

Customer PU Cost
Customer teams pay approximately $15-20 million per season for a PU supply contract. This covers 4 complete power units per car (8 total per team), plus engineering support, on-track personnel, and software updates. The FIA caps PU pricing to prevent manufacturers from charging prohibitive rates.
Works vs Customer Advantage
Works teams get the latest upgrades first, deeper integration between chassis and PU development, and bespoke engine mapping. Customer teams receive identical hardware (FIA-mandated) but typically run the manufacturer's software with less customization. The gap has narrowed under the cost cap — but works teams still hold an integration advantage worth 0.1-0.3s per lap.
Why Supply?
Manufacturers supply customer teams for several reasons: revenue ($15-20M per customer offsets PU development costs of ~$100M/year), data (more cars running the PU means more operational data across different chassis philosophies), and FIA requirement (manufacturers must supply at least one customer team if asked).
The Renault Exit
2026 is the first season without a Renault engine since 2000. Alpine switched to Mercedes customer PUs — an acknowledgment that Renault's in-house PU couldn't compete. The 2026 regulations (no MGU-H, simpler architecture) were supposed to level the field, but Renault chose to exit rather than invest in the new spec.

Competitive Analysis

How PU performance correlates with results

Constructor Points by PU Manufacturer
Key question: Can a customer team beat the works team using the same engine? In 2026, McLaren (Mercedes customer) is outscoring several works teams. Historically, customer teams rarely win championships — the last was Red Bull with Renault power in 2010-2013. The integration advantage of being a works team is real but not insurmountable.
