F1 at crossroads over future engine regulations
Formula 1 is grappling with two critical engine discussions that could reshape the sport's technical direction. The first focuses on immediate fixes for this year's power units, while the second debates whether to revert to naturally aspirated V8 engines by 2030 or 2031.
FIA president pushes for V8 revival
Mohammed Ben Sulayem, president of the FIA, is advocating for a return to naturally aspirated V8 engines with a minimal hybrid system-similar to the regulations last used in 2013. His proposal aims to address concerns over cost, weight, and fan engagement, though it contradicts the broader automotive industry's shift toward electrification.
Ben Sulayem argues that V8s would reduce costs, improve sustainability, and restore the iconic engine sound that many fans associate with F1's golden era. In an interview with Car and Driver, he stated, "For the sake of sustainability, business, price, efficiency, light weight, and sound for the fans, I think you are ticking many boxes here."
Weight and performance trade-offs
The current hybrid power units weigh 185kg, including the engine, turbo, and electrical components. By comparison, the 2.4-litre V8s used in 2013 weighed 130kg, with the internal combustion engine alone at just 95kg. However, modern F1 cars start races with only 90kg of fuel, compared to 160kg in 2013, offsetting some of the weight advantage.
Insiders suggest a lighter, simpler engine could allow for narrower and lighter chassis, though safety advancements like the halo head-protection system have increased overall car weight.
Fan noise and commercial concerns
Ben Sulayem's proposal also emphasizes the return of louder engines, which he believes would enhance the fan experience. However, there is no concrete data on how many fans prefer the sound of naturally aspirated engines over the current turbo hybrids.
A significant portion of F1's recent growth has occurred since the introduction of hybrid engines in 2014, coinciding with Liberty Media's acquisition of the commercial rights and the success of the Drive to Survive series. Louder engines could also jeopardize races in urban centers like Miami, Las Vegas, and Monaco, where noise restrictions are in place.
"The fans and corporate guests who have come to the sport in the past 12 years have no conception of what it is like to attend a race where they cannot hold a conversation while the cars are on track,"
Industry sources
Manufacturers and drivers divided
While manufacturers are open to discussing engine changes, there is no consensus on the specifics. Mercedes has expressed support for V8s but cautioned against losing relevance to road-car technology. Toto Wolff noted, "How do we give it enough energy from the battery side to not lose connection to the real world? Because if we swing 100% combustion, we might be looking a bit ridiculous in 2031 or 2030."
Honda, another key player, stated that a return to V8s "is something we should discuss healthily," while Audi has indicated a preference for retaining turbocharging for efficiency and road relevance.
Drivers have also weighed in, with George Russell pointing out that while the 2000s era of naturally aspirated engines was "the purest Formula 1 we've ever seen," the racing was often less competitive.
Short-term fixes for 2026 engines
Separate from the long-term debate, F1 is working on immediate adjustments to the 2026 engine regulations. The current hybrid power units have faced criticism for excessive energy management, particularly in qualifying, where drivers must balance power deployment with fuel conservation.
Recent changes introduced at the Miami Grand Prix allowed faster energy recovery and reduced total energy usage, but further modifications are expected. Options under consideration include increasing the fuel-flow limit, expanding battery capacity, or shortening race distances to accommodate larger fuel tanks.
A decision on these adjustments is expected within the next two weeks to ensure implementation for the 2027 season.
Timeline and next steps
The next major engine regulations are not due until 2031, but Ben Sulayem is pushing for changes as early as 2030. The FIA could theoretically impose new rules unilaterally, but doing so risks alienating manufacturers, including Audi, Ford, and General Motors, which recently entered the sport.
With the current Concorde Agreement expiring at the end of 2030, stakeholders are under pressure to reach a consensus. The FIA is expected to present a formal proposal soon, though the development of new engine regulations typically takes several years.
