Formula 1 engines, F1 power unit manufacturers, 2026 F1 engine suppliers
A factual map of who powers whom in 2026—and what the combustion, electrical, energy-recovery, fuel and cooling architecture demands from modern manufacturing.
The grid is a supply network
Five power-unit manufacturers support eleven constructors. Mercedes supplies Mercedes, McLaren, Williams and Alpine. Ferrari supplies Ferrari, Haas and Cadillac. Red Bull Ford supplies Red Bull Racing and Racing Bulls. Honda supplies Aston Martin. Audi supplies its own factory team. That map matters because a team name on a chassis does not always identify the engine, gearbox, fluids or technical supply chain behind it.
What changed for 2026
The 2026 formula retains a turbocharged 1.6-liter V6 architecture but increases the electrical contribution, removes the MGU-H and puts a much stronger MGU-K at the center of deployment and recovery. The FIA describes roughly 400 kW from the combustion side and 350 kW from the electrical side, with energy recovery up to 8.5 MJ per lap. Those rules increase the importance of electrical integration, insulation, thermal control, precision assembly and repeatable validation.
Manufacturing consequence
A power unit is not one machining problem. It is a controlled system of cast, forged, machined, coated, balanced, bonded, wound and inspected parts. Surface integrity, oil and coolant passages, dimensional stack-up, rotor balance, sealing, cleanliness and traceability all matter. MBB does not publish secret tolerances; teams do not release them. The useful lesson is how the workflow connects design intent to process capability and verified parts.
Fuel is engineered with the engine
The FIA's 2026 rules require advanced sustainable fuel. Public team sources show fuel partners developing formulations with the power-unit manufacturer rather than treating fuel as an afterthought. Combustion testing, lubricant behavior and materials compatibility are system-level development questions, which is why a fuel logo can represent a technical role when the team expressly documents one.

- What functional requirement is this process or inspection intended to control?
- Which drawing, model and revision define the current configuration?
- What material condition and upstream process history enter this operation?
- How will the result be verified, recorded and connected to the part identity?
- What is public fact, what is engineering inference and what remains proprietary?
