The 2026 Australian Grand Prix, opening the Formula 1 season at Albert Park Circuit in Melbourne, marked Sergio ‘Checo’ Pérez's return to the category after a year away. The 36-year-old Mexican now races with Cadillac alongside Valtteri Bottas, in the debut of the team backed by General Motors. The car is named MAC-26, honoring 1978 champion Mario Andretti.
In the first free practice on Thursday, March 5 (Mexico time), Pérez finished 20th with a time of +4.353 seconds behind leader Charles Leclerc, who clocked 1:20.267. Leclerc beat his Ferrari teammate Lewis Hamilton by +0.469; Max Verstappen was third with +0.552, and Isack Hadjar fourth with +0.820. Pérez completed 14 laps, including four on medium tires; his right mirror detached due to vibrations, and he experienced a minor spin from technical issues but continued. A Virtual Safety Car was deployed due to a failure in Alex Albon's car.
Other notable results include Oscar Piastri sixth with +1.075, Lando Norris 19th with +4.124, and Bottas 17th with +3.755. Fernando Alonso did not participate, and Lance Stroll recorded +30.067 for Aston Martin.
Before the session, Pérez messaged his fans: “Hola a todos. Quiero mandarles un fuerte abrazo, agradecerles todo su apoyo que me han dado este año que estuve fuera y con este regreso también. Espero que tengamos muy buenos momentos y que podamos disfrutar mucho este regreso”. Director Graeme Lowdon stated: “El debut del Cadillac Formula 1 Team es uno de los momentos más orgullosos de mi carrera. Ha sido una tarea enorme llegar hasta este punto”.
Pérez has a two-year contract until 2027, with talks for an extension based on team progress. After Bahrain tests, he said: “Por el momento, el equilibrio del coche se siente bien. Creo que tenemos un coche equilibrado”. The season introduces changes like DRS elimination and 50/50 hybrid engines.
The event airs in Mexico on F1 TV, Sky Sports, Izzi Go, and DAZN. The circuit is 5.2 km long, with 58 laps for 306.124 km; the lap record is Leclerc's 1:19.816 (2024), and the last winner was Norris in 2025.
