The design phase
Every F1 car begins as a digital model. Aerodynamicists use computational fluid dynamics (CFD) to simulate airflow around thousands of design variations. The best designs are then tested as scale models in the wind tunnel, where real-world data validates the simulations.
The entire design process takes months, and it involves hundreds of engineers working in parallel. The chassis team designs the monocoque, the suspension team designs the wishbones, the power unit team designs the engine and hybrid systems, and the aerodynamics team shapes every external surface.
The monocoque: the car's backbone
The monocoque is the single most important component of an F1 car. It is the survival cell that protects the driver, and it is also the structural foundation to which every other component is attached.
Monocoques are made from carbon fiber composite, laid up by hand in a clean room and then cured in an autoclave at high temperature and pressure. The process takes several weeks, and each monocoque must pass a series of FIA crash tests before it can be used in a race car.
Manufacturing the components
While the monocoque is being built, the rest of the car's components are manufactured simultaneously. The suspension wishbones are CNC-machined from aerospace-grade aluminum or titanium. The gearbox casing is made from carbon fiber. The brake discs are manufactured from carbon-carbon composite, a material that can withstand temperatures of over 1,000°C.
Increasingly, teams are using 3D printing (additive manufacturing) to produce complex components that would be impossible to machine conventionally. Brake ducts, cooling ducts, and some suspension components are now 3D printed, allowing for geometries that optimize airflow and reduce weight.
Assembly and testing
Once all components are manufactured, the car is assembled in the team's factory. The process takes about two weeks per car. The monocoque is placed on a jig, the power unit is installed, the gearbox is bolted on, the suspension is fitted, and the bodywork is attached.
Before the car leaves the factory, it undergoes a series of systems checks: electrical systems, hydraulic systems, cooling systems, and software calibration. Only when every system passes its checks is the car signed off for shipping to the circuit.
The 2026 challenge
The 2026 regulation changes have made the manufacturing process more complex. The new power units, with their increased electrical component, require new cooling systems and new packaging solutions. The Active Aero system adds complexity to the wing manufacturing process. And the lighter minimum weight target means every component must be optimized for weight reduction.
