The recent announcement by Mohammed Ben Sulayem, the president of the FIA, regarding Formula 1’s potential return to V8 engines has sparked significant discussion within the motorsport community. This statement, made at the Miami Grand Prix, caught the attention of many, particularly because the prospect seemed unlikely just a year ago.
The current hybrid power units, which were introduced at the start of this season and are expected to remain in use until 2030, have faced considerable criticism. Ben Sulayem’s comments on V8 engines appeared to solidify the notion that a shift might be imminent. He stated, “It’s coming. Ultimately, it’s just a matter of time. In 2031, the FIA will have the authority to implement this change without needing votes from the Power Unit Manufacturers (PUMs). However, we would like to introduce it a year earlier, as there is a growing demand for it.”
While many newer fans of Formula 1 may not have a strong connection to V8 engines, those who have followed the sport longer are likely to feel nostalgic about their return. The last time F1 utilized V8 engines was in 2013, after which the series transitioned to 1.6-liter V6 hybrid engines, a move that aligned with the automotive industry’s shift toward electrification.
Although there was a modification to the engine regulations in 2022, the overall design of the engines remained stable for twelve seasons. The new 2026 engine model, while technologically advanced, has introduced several challenges. The hybrid system has almost tripled the electric power output from 120 kilowatts to 350 kW, resulting in a near equal distribution of power between the internal combustion engine and electric components. Consequently, drivers spend considerable time managing battery energy, which limits their ability to maintain full throttle for extended durations.
Additionally, the hybrid engines have become heavier, with a minimum weight of 185 kilograms, an increase of 40 kilograms from 2025, in stark contrast to the 95-kilogram minimum for the V8 engines used in 2013. The cost associated with these power units has also raised concerns. F1 CEO Stefano Domenicali emphasized the need for sustainable business practices, noting, “The cost of the power unit is too high, that is definite. We must ensure that this business remains viable.”
Currently, there is a cap of $190 million on spending for power unit manufacturers, with each manufacturer expected to have invested approximately $660 million in their engines by the end of this season. This financial burden could complicate the transition back to V8 engines, as manufacturers may resist changes after significant investments in the hybrid systems.
Despite these challenges, the current hybrid engines have played a role in increasing the number of manufacturers involved in F1. The 2026 power unit regulations were designed to reflect the automotive industry’s push toward simpler and more electrified engines. This led to Audi entering the sport and developing its own engine, while General Motors announced Cadillac would become a full works team by the end of the decade.
Honda’s recent re-entry into F1 as a key player also highlights the evolving landscape. After exiting in 2021, Honda reversed its decision due in part to the new regulations for 2026, recognizing the potential value in investing in advanced technology. “Our investment in motorsport, particularly in Formula 1, is strategic for enhancing the long-term competitiveness of Honda’s automotive business,” stated Shota Yokono from Honda Racing Corporation.
As discussions about the future power units continue, the challenge remains to balance the desire for reduced electrification with manufacturers’ willingness to invest. Mercedes team principal Toto Wolff expressed openness to revisiting engine regulations, stating, “We love V8s. It brings back great memories. From our perspective, it’s a true Mercedes engine that revs high.” He proposed the concept of a “mega engine,” which could combine a powerful combustion engine with substantial electric energy support.
