The Australian GP 2026 marks the opening of the Formula 1 season at the Melbourne circuit and brings back Sergio ‘Checo’ Pérez, who now competes for the new Cadillac team. The weekend begins with the initial practice sessions at Albert Park, where Pérez joins Finnish driver Valtteri Bottas in Cadillac's debut in the championship. These early sessions are crucial for evaluating the performance of the new Cadillac vehicle and observing how the cars perform under the new technical regulations set for F1 2026, kicking off the American team's sports project backed by General Motors.

In the first practice session of the Australian GP, Pérez encountered difficulties, finishing in 20th place, a notable gap of +4.353 seconds behind the session leader, Charles Leclerc of Ferrari, who clocked a time of 1:20.267. This performance may indicate the challenges that the Cadillac team faces as they adapt their car to meet the rigorous demands of Formula 1 racing. Pérez's position reflects the competitive nature of the field and the learning curve that new teams typically experience as they establish themselves in the championship.

Despite this rough start, the initial practice sessions serve as an important benchmark for the Cadillac team. Rapid adjustments and evaluations will be necessary for Pérez and his team as they prepare for upcoming qualifying sessions and the race weekend. The goal for Pérez will now be to improve his performance as he aims not only for a competitive position but also to contribute positively to Cadillac's inaugural season in Formula 1.
