Cadillac details MAC-26 upgrade for Canadian GP

Cadillac has outlined the next update to its debut Formula 1 car ahead of the Canadian Grand Prix, extending a race-by-race development push in its first season on the grid. Motorsport.com reported on May 19 that the team’s MAC-26 will receive a further package in Montreal after Cadillac introduced its first major upgrade in Miami. The move keeps the American entrant on an aggressive early-season schedule as it tries to add pace with Sergio Perez and Valtteri Bottas in its first year of competition. Cadillac’s next race is the Canadian Grand Prix, according to the team’s official site. ### What is Cadillac changing in Montreal? Motorsport.com reported on May 19 that the MAC-26 “will benefit from a further update in Montreal,” describing it as Cadillac’s newest package for the Canadian Grand Prix. The report said the changes are an iteration of earlier aerodynamic and chassis work rather than a clean-sheet redesign. (motorsport.com) Miami was the first reference point for the new package. A team preview published May 19 said Cadillac introduced its first major upgrade package at the Miami Grand Prix and that it delivered “an increase in aerodynamic load and overall performance.” The same preview said the team logged double-car finishes in both the sprint and the grand prix in Miami. (motorsport.com) ### Why is the car called the MAC-26? Cadillac named its first Formula 1 car the MAC-26, Motorsport.com reported earlier, after Mario Andretti, the 1978 Formula 1 world champion who was central to the project’s formation. The “26” refers to Cadillac’s debut season in the championship. (motorsports.media) Formula 1’s official team page says Cadillac joined the grid for 2026 as the sport’s 11th team. The same page lists Perez and Bottas as the race drivers and Colton Herta as test driver, while noting General Motors has been approved as an F1 power-unit supplier from 2029. ### How urgent is Cadillac’s development cycle? Bottas said in a Motorsport.com report published in March that Cadillac planned updates “at each of the next few grands prix,” underlining how quickly the team intended to develop the car in its opening races. (motorsport.com) The same report said Perez was targeting points by the summer break as the team searched for performance. (formula1.com) Perez told Motorsport.com in a separate report that Cadillac was “in a massive hurry to find performance.” That assessment came as the team tried to turn an encouraging start into more consistent pace against established rivals. ### How does the Canada update fit with Cadillac’s wider rollout? (motorsport.com) Cadillac’s official team site says the project is “bringing in a new team” for the 2026 FIA Formula One World Championship, while Cadillac’s racing page lists Canada as the next stop on the schedule. The Montreal package therefore arrives as both a competitive step and a high-visibility North American race for the new entrant. (motorsport.com) The Canadian Grand Prix is also one of the first chances for Cadillac to show progress after its Miami launch phase. The team’s May 19 preview tied the car’s reliability and first major upgrade directly to its run into Montreal. ### Where else is Cadillac showing up this week? EA Sports F1 posted a reveal trailer page for the F1 25: 2026 Season Pack, with the video set to premiere on May 20. (cadillacf1team.com) Third-party gaming reports citing EA said the expansion will add the 2026 season content, including Cadillac and Audi, to F1 25. May 20 is the next dated milestone. EA Sports F1 has scheduled the trailer premiere for that day, while Cadillac’s on-track next step is the Canadian Grand Prix in Montreal, where the updated MAC-26 is due to run.
