FIA closes off backdoor route to obtain rivals’ F1 engine secrets
As the F1 car makers work on designing the new turbo-hybrid power units for 2026, the power balance between combustion and electrical energy will shift to a 50/50 split between batteries and the internal combustion engine (ICE). Audi and Red Bull Powertrains have an opportunity to join as suppliers, increasing competition on the grid. However, the FIA has made amendments to the 2026 engine rules to prevent manufacturers from gaining an unfair advantage through fuel partners. The regulations restrict fuel suppliers from conducting engine bench testing with a full V6 and limit the transfer of engine intellectual property (IP) through fuel suppliers. Personnel movement between fuel suppliers and manufacturers is also restricted to prevent IP transfer.
