Cadillac is "thrilled" as the popularity of V8 engines increases in F1.

      Cadillac and Formula 1's chief executive, Stefano Domenicali, have expressed new support for the increasing calls to reintroduce V8 engines soon. This discussion arises as Formula 1 faces criticism regarding current regulations, with many drivers feeling dissatisfied with the heavy focus on battery usage and energy management.

      General Motors, the parent company of Cadillac, is among those encouraged by this dialogue. GM president Mark Reuss stated that the American automaker would be open to a future that includes V8 engines. "We know how to make V8 engines," Reuss mentioned at the Indycar race in Detroit. "We have a rich history with the GTP, GTD Pro, and we produce these engines right here in Michigan. We’re excited about this opportunity in Formula 1."

      Reuss also emphasized that Cadillac remains fully dedicated to its current Formula 1 engine program. "We’re diving deeper into the 2.4-litre turbo V6s for 2028," he explained. "I don’t see that changing because we’ve all invested, and it’s great."

      These remarks are significant, as Cadillac was accepted into Formula 1 with the understanding that it would eventually develop its own power units rather than solely act as a customer team for Ferrari. General Motors launched its Formula 1 engine division in North Carolina last year, led by seasoned engineer Russ O’Blenes, and is already participating in engine manufacturer meetings, despite not yet providing its own units. Transitioning to a simpler V8 formula could greatly facilitate Cadillac’s journey to becoming a full works manufacturer.

      Formula 1 CEO Stefano Domenicali has also been increasingly vocal on this topic. In an interview with L’Equipe, the former Ferrari leader suggested that a future focused on sustainable fuels and combustion engines would align better with the sport’s heritage. "Personally, I envision a future where green fuels play a key role, altering the current balance with the electric component and reinstating the importance of the internal combustion engine," Domenicali stated. "This is the essence of motorsport."

      Domenicali believes this shift would help Formula 1 address issues concerning the size and weight of the current generation of cars. "It would enable us to significantly decrease overall weight, allowing for more agile and compact cars that can reach maximum performance," he noted. The Italian is confident that long-time fans—often referred to as ‘purists’—would welcome this change. "I’m certain that this evolution will satisfy the traditional enthusiasts," added Domenicali.

      Support for V8 engines has surged in recent weeks, with FIA president Mohammed Ben Sulayem also endorsing a return to simpler, lighter, and more powerful units by 2030 or 2031.
