In Formula 1, the transition to V8 engines in 2031 is being discussed.

      In 2026, Formula 1 transitioned to next-generation hybrid power units, where power is distributed equally between the electric part of the power unit and the internal combustion engine in a 50:50 ratio. However, preseason tests and the first races showed that this decision was unsuccessful largely because the maximum power mode is available to drivers for only short periods, and the energy reserve is insufficient for long straights. In April, during a forced break in the season, representatives from Formula 1, the FIA, teams, and power unit manufacturers will hold a series of meetings to discuss options for changing the regulations. However, this concerns short-term adjustments to the rules, ideally by the Miami Grand Prix, while in the long term, the current power units will remain for several more years. Nevertheless, discussions about power units for 2031 have already begun in Formula 1. One option being considered is to exclude the hybrid component, and to ensure the racing series maintains an eco-friendly image, carbon-neutral fuel, which teams already switched to in 2026, would be sufficient. All these factors pave the way for the return of classic naturally aspirated engines to Formula 1; however, power unit manufacturers are likely to oppose this. Since turbocharged engines are currently used in production cars with rare exceptions, the next generation of Formula 1 power units will also be turbocharged. According to Auto Motor und Sport, the current favorite is a 2.4-liter turbocharged V8 engine. However, there is still a long way to go before the final specification for the 2031 power unit is approved. Nevertheless, there are chances for the return of the V8, as this option was previously suggested by FIA President Mohammed ben Sulayem, and Formula 1 CEO Stefano Domenicali hinted last year that the future could be for the V8.
