Formula 1 is evaluating potential regulatory changes for the post-2030 era, including the possible return of V8 engines by 2031. One proposal to address car weight involves reintroducing mid-race refueling, a practice that has been discontinued since 2010.

Several team principals, including James Vowles of Williams, Peter Bayer, and Ayao Komatsu of Haas, have expressed opposition to this proposal. Komatsu specifically noted that refueling could complicate the experience for spectators and alter the logic of qualifying sessions, stating a preference for cars to remain as light as possible during maximum performance efforts.
