Return of V10 engines in F1 getting closer: discussions for early introduction with E-fuels. For weeks, there has been talk of a highly intriguing return of V10 engines in F1.

Formula 1 appears intent on completely overturning the technical direction it has taken. From an extremely complex and hybrid technology—one that is above all cold—to one that would reignite the passion of fans. According to recent circulating reports in the F1 world, the return of V10s is closer than ever, and could even be brought forward, thanks to the use of e-fuels.

The world of Formula 1 has been debating its future for weeks, amidst increasingly complex regulations and new manufacturers entering the sport. The bold idea is to approve an emergency plan to restore the excitement of F1 racing. Lighter and simpler cars, but above all, ones that express themselves on track with the sound of one of the most legendary engines ever created. The golden era of the top motorsport series dates back to the early 2000s when naturally aspirated V10 engines reigned supreme.

These power units reached extremely high rev limits, producing acoustic frequencies that made grandstands tremble. It was no longer just noise but a so-called symphony that all fans long to hear again.

However, this would require an extension of the 2026 power unit regulations by another two years, skipping straight to V10s. Such a decision would put Audi in crisis while significantly benefiting Cadillac. The new American team, set to join in 2026, will initially use Ferrari’s power unit before transitioning to its own in 2028.

According to reports from AMuS, the dream of seeing V10s return seems closer than ever to becoming a reality. The F1 leadership is highly concerned about the new regulations, which introduce new cars, complex power units, new tires, and the uncertainty of synthetic fuels. For this reason, the return of V10s could be a lifeline for the series, eliminating the risk of teams leaving.

FIA Under Pressure Over 2026 Regulations
Several teams have raised significant concerns about the 2026 regulations. There is strong unity among teams regarding safety issues related to energy recovery. This could lead to major performance gaps between teams that manage to optimize the upcoming power units. Hence, the idea of extending the current rules and switching directly to V10s in 2029 has emerged.

Such a move would put the FIA—and its president—under intense pressure. This scenario would be ideal for the Americans, as Cadillac would have to design “simpler” V10s. The pressure on the FIA has been confirmed by the working group specifically established to bring back naturally aspirated 10-cylinder engines. On this issue, teams are divided, depending on what best fits their political agendas.

It’s an upside-down world, with Honda and Audi strongly pushing for the new regulations to take effect in 2026. Even Toto Wolff has confirmed that the 2026 engines are necessary “because we don’t have enough current engines available.”

The implementation of the 2026 regulations must go forward, as any extension would trigger legal actions from affected parties. However, the duration of the next regulatory cycle could be reduced from five to three years. In any case, time is running out, and no decision is expected before the summer.
