The Fédération Internationale de l’Car (FIA), the worldwide physique that oversees motor sport, is increasing its use of Siemens digital twin expertise as a part of a brand new partnership. Siemens has joined the FIA’s International Partnership Programme and can act because the official digital twin sponsor.
The FIA will depend on Siemens’ Xcelerator portfolio to assist design and check aerodynamic ideas for single-seater race vehicles, from Formulation 1 to 4. With Siemens’ Designcentre NX software program, engineers can construct and alter digital fashions and run computational fluid dynamics (CFD) simulations. These let the FIA optimise efficiency and security and lower down on the necessity to construct bodily prototypes for wind tunnel testing.
Since 2022 the FIA’s aerodynamics workforce has produced over 14,000 computer-aided design (CAD) elements and run over 10,000 CFD exams utilizing Siemens’ instruments. Shifting a lot of this work right into a digital atmosphere has helped decrease the carbon footprint of automotive growth, the muse states.
FIA’s imaginative and prescient for racing
Jason Somerville, the FIA’s head of aerodynamics, mentioned, “Siemens offers us the precision instruments to design and check advanced aerodynamic ideas just about, decreasing environmental impression whereas bettering efficiency and security. The expertise is vital to making sure that racing stays nearer, fairer, and extra aggressive.”
Past the FIA’s work with Siemens, Method 1 push the bounds of digital engineering. Latest research in 2025 spotlight how CFD, digital twins, and machine studying are altering the way in which race vehicles are designed and refined.
One challenge led by Alpine F1 and Oxford Brookes College examined adjustments to a automotive’s diffuser utilizing CFD instruments. Small tweaks, like including a lateral vane, delivered massive good points: a couple of 13% enhance in downforce and a 5% lower in drag in comparison with the baseline mannequin. The outcomes present how even refined design changes can have a measurable impression on efficiency when explored in a digital atmosphere.
Entrance wing design can be seeing a shift. A examine revealed in 2025 mixed conventional CFD runs with a physics-informed neural community to hurry up predictions of aerodynamic behaviour. The mannequin achieved excessive accuracy – virtually 97% for drag and 98% for elevate – and diminished the time wanted to guage new wing ideas. This sort of hybrid digital/bodily method permits groups to run by extra design concepts in much less time, a key benefit below Method 1’s strict price and testing limits.
One constructor studies aiming for round 1,000 CFD simulations per week, supported by sooner post-processing instruments that may give outcomes to engineers almost immediately. The potential to look into 1000’s of choices on-line, relatively than constructing bodily prototypes, offers groups extra probabilities to search out aggressive benefits.
CFD additionally performs a task in getting ready for the 2026 regulatory adjustments. Analysts have used simulations to foretell how new aerodynamics guidelines will alter airflow across the diffuser and wings, serving to groups put together methods earlier than the primary automotive reaches the observe.
Subsequent steps within the Siemens digital twin partnership
The FIA will enhance its use of Siemens’ Teamcentre® X software program for managing product knowledge and collaboration in championships, and broaden its use of Siemens’ simulation instruments, together with Simcentre® X, Simcentre™ Amesim™, Simcentre™ STAR-CCM+, and Simcentre™ HEEDS.
By way of its International Partnership Programme, the FIA works with organisations that share its targets round innovation, security, and sustainability in motor sport.
