The Cadillac MAC-26 is a Formula One car designed and built by the Cadillac Formula 1 Team to compete in the 2026 Formula One World Championship. It is currently being driven by Sergio Pérez and Valtteri Bottas, marking Cadillac's debut season in Formula One. The car made its competitive debut at the 2026 Australian Grand Prix on March 8, 2026.
History Prior history and attempts to enter Formula One
The Cadillac Formula 1 Team is the most recent entry onto the Formula One grid, and the brand's first appearance in the sport as a constructor. On two occasions in the 1950s, Cadillac-engined Kurtis Krafts were entered for the Indianapolis 500 while the race was part of the Formula One World Championship. A 2023 attempt to enter the sport as Andretti Cadillac through General Motors (GM) and Andretti Global, led by Michael Andretti, son of 1978 World Champion Mario, was vetoed by the Formula One Group, despite the acceptance of the bid by the Fédération Internationale de l'Automobile (FIA), with the proviso that Formula One Group would reconsider should GM agree to enter as a fully-fledged works team. A second proposal was submitted in 2024, now led by Dan Towriss through Andretti's owner TWG Motorsports and renamed Cadillac, and was approved by the Formula One Group.
2026 regulation changes and development context
Significant changes to Formula One's technical regulations were introduced for 2026, affecting both the chassis and engine. For 2026, Cadillac use customer Ferrari Tipo 067/6 V6 turbo hybrid engines, with the works General Motors power unit scheduled to be introduced for the 2029 season.
Launch and pre-season The car made its first appearance on track during a private shakedown at Silverstone Circuit in January 2026, before participating in an extended private January 26–30, 2026 shakedown at the Circuit de Barcelona-Catalunya with 9 of the 10 other teams.
Before being revealed, the MAC-26 was shipped to Times Square, New York, where a timer and drape stood until the car was officially unveiled. On February 8, 2026, a short Cadillac commercial aired during a break, unveiling the livery. The team said that their decision to release the commercial during the Super Bowl and ship the car to Times Square was to maximize its visibility to the public. The commercial was directed by Sam Piling and scored by Max Richter. Shortly after the commercial aired, the car was also revealed at Times Square. A longer video, integrating President John F. Kennedy's 1962 speech about putting a man on the Moon, was released after the Super Bowl commercial had aired. Liveries During the Barcelona pre-season shakedown, the MAC-26 wore an all-black livery with an angled Cadillac logo on both sides.
Race liveries The MAC-26's race livery was initially an asymmetrical design: black on one side and white on the other. This was the first asymmetrical Formula One livery since the BAR 01 of 1999, which was white and red on one side, and blue and yellow on the other. At the Austrian Grand Prix, the team debuted a revised symmetrical, predominantly white livery, citing positive fan reception of its 2026 Miami Grand Prix livery as part of the reason for the change.
Special liveries For the team's first home race, the 2026 Miami Grand Prix, Cadillac launched a special Stars and Stripes livery. The colors of the American flag were blended into Cadillac’s signature black and white color scheme.
For the 2026 British Grand Prix, Cadillac launched a special livery to mark 250 years of American independence as the Grand Prix weekend fell on Independence Day.
Name On February 27, 2026, Cadillac announced the chassis name to be MAC-26, with "MAC" for "Mario Andretti Cadillac", after 1978 World Champion Mario Andretti, father of Michael Andretti, who previously attempted to enter the grid as Andretti Global, before changing its entry bid to Cadillac.
