The FIA and Formula E will allow manufacturers to introduce hardware upgrades to their Gen4 cars through a new token-based system, replacing the current mid-cycle Evo update format.
The process is similar in principle to the system used in the Hypercar class of the FIA World Endurance Championship, where manufacturers are allocated five joker upgrades over a five-year homologation cycle. However, unlike the WEC model, where upgrades can be applied broadly across the car, the FIA will assign a fixed number of tokens to specific components.
