Formula 1 is set to hold two crucial meetings on Wednesday during the final 2026 pre-season test in Bahrain, focusing on power unit disputes and race start procedures. These discussions could shape the upcoming season opener in Australia on March 8. The Power Unit Advisory Committee and F1 Commission will address ongoing concerns raised during earlier testing.
The final pre-season test for the 2026 Formula 1 season begins on Wednesday at the Bahrain International Circuit, running from February 18 to 20. Coverage is available live on Sky Sports F1 from 7am to 4pm each day. However, the day's most significant developments may occur off-track, with two key meetings scheduled that could influence the season's early races.
The Power Unit Advisory Committee (PUAC), comprising the five engine manufacturers—Mercedes, Red Bull, Ferrari, Honda, and Audi—along with the FIA and Formula One Management (FOM), will tackle a dispute over compression ratio limits in the new power units. The limit has been reduced to 16.0 from 18.0 under previous rules, but measurements are currently taken only when engines are not at full temperature. Early reports suggested Mercedes and Red Bull exploited a loophole, prompting objections from Ferrari, Honda, and Audi. Red Bull's engine chief Ben Hodgkinson dismissed it in January as "a lot of noise about nothing." Mercedes' Toto Wolff initially urged rivals to "get your s*** together" and called their complaints "excuses."
By the first test on February 11 in Bahrain, Wolff adopted a more conciliatory stance, acknowledging possible changes to Mercedes' power unit. Red Bull has since aligned with the other manufacturers, pushing for the limit to apply at all times. Rivals suspect Mercedes operated below full capacity during that test to argue against alterations. A rule change requires a super majority from the FIA and FOM, potentially impacting Mercedes-powered teams like McLaren, Williams, and Alpine.
The F1 Commission, including representatives from the 11 teams, FIA, and FOM, will discuss race start procedures. New power units pose challenges for drivers preparing from the grid, with most teams seeking extra time before lights out for safety. Ferrari opposes changes, having designed their unit around the current setup. McLaren's Andrea Stella emphasized safety, stating: "We are not talking about how fast you are in qualifying, we are not talking about what is your race pace, we are not talking about safety on the grid. There are some topics which are simply bigger than the competitive interests. And for me, having safety on the grid, which can be achieved with a simple adjustment, is just a no-brainer. It's just a bigger interest."
Ferrari's Fred Vasseur stressed the need for clarity: "Now the most important [thing] is to take a decision because to stay grey is not a solution, it has to be black or white. It's important for us, it's important for everybody. It's also important for you [the media] and the fans. We want to clarify this the sooner the better."
A separate report confirms the power unit meeting date aligns with the March 1 engine homologation deadline.
