The Cadillac Formula 1 Team has detailed the complex engineering process behind designing front brake ducts for its 2026 race car. Brake discs in F1 regularly exceed 1,300 degrees Fahrenheit as vehicles decelerate from over 200 mph at more than four times the force of gravity.
Highlights
- F1 brake ducts must balance FIA regulatory compliance with critical cooling requirements to prevent component failure
- GM Motorsports uses 3D-printed prototypes to validate computer simulations before final manufacturing
- Over 500 engineers are working to ensure thousands of chassis components function properly for the March 2026 Australian Grand Prix debut
- Thermal management remains essential as braking systems convert kinetic energy to extreme heat during high-speed deceleration
FIA Regulations Shape Design Parameters
The Fédération Internationale de l’Automobile establishes strict regulations governing brake duct specifications. Nick Schaut, design engineer with GM Motorsports, notes the team operates within significant constraints and restrictions when developing these components.
Aerodynamicists initiate the design process by ensuring brake ducts satisfy both FIA rules and the team’s specific cooling requirements. Design and manufacturing teams then convert computer models into physical components while maintaining close adherence to original specifications.
Prototyping and Validation Process
GM Motorsports employs 3D printing to create prototype brake duct components. This approach validates computer simulation predictions in physical space before committing to final production.
Chad Vermeulen, GM Motorsports Aerodynamics Surface Designer, explains the primary objective: ensuring the braking system avoids thermal damage to itself and adjacent components.
Integration Challenges
The front brake duct represents just one of thousands of individual parts comprising an F1 chassis. The Cadillac Formula 1 Team faces the challenge of designing all these components from scratch for its grid debut.
The team’s combined expertise in design, simulation, prototyping, and aerodynamics will be tested when the car competes in Australia in March 2026.
