F1 | Alonso criticizes compression ratio: Mercedes engine out of regulation
Fernando Alonso did not hold back his thoughts on the engine compression ratio and the Mercedes power unit controversy that has erupted in recent days. During the launch of the new Aston Martin AMR26, the car with which the Asturian driver will compete in 2026, Fernando Alonso found time to take a subtle jab at the Mercedes engine and comment on what may unfold in the coming days.
The engine issue is increasingly monopolizing the attention of teams, engineers, and fans alike. With the upcoming two test sessions in Bahrain, the situation appears poised to escalate further. A final decision from the FIA is also expected, following an agreement between F1, the FIA, and the four other engine suppliers to find a solution. Even FIA technical director Nikolas Tombazis confirmed irregularities, and now the Spanish driver is calling for clarity.
A dig at Mercedes
During the AMR26 presentation, Alonso addressed the Mercedes engine case directly. “It would be better to start with the same rules for everyone,” the former Ferrari driver said. “It’s not a good idea to start behind someone who is exploring something that was never meant to be explored.”
Fernando Alonso also acknowledges that this is part of the competitive spirit of Formula 1, but always within the respect and limits of the gray areas: “This is also Formula 1. You have to understand that everything that happens is controlled by the FIA, and we need to accept the final decision.”
He added that he places his full trust in the FIA: “I trust the FIA to monitor, control, and clarify the situation.”
Finally, Fernando Alonso expressed confidence and hope for his own team and the new Honda engines: “I have faith in Honda and Aramco to ensure that our engine will be sufficiently competitive and compliant.”
Fernando Alonso’s comments during the AMR26 launch therefore underscore the intense political and technical friction that defines the start of this new 2026 regulatory era. By publicly questioning the legality of the Mercedes compression ratio, the Spaniard has signaled that the battle for the championship is already well underway off the track. As the FIA moves to finalize its ruling before the first race, the focus remains on whether a level playing field can be established or if this initial technical “gray area” will set the tone for the season-long development race between F1’s elite power unit manufacturers.
