McLaren has made the strategic decision to refrain from participating in the first day of the Formula 1 testing session taking place behind closed doors in Barcelona. This choice is aimed at optimizing the development timeline for their new title defender, the MCL40.
In contrast, other teams such as Audi, Cadillac, Racing Bulls, and Alpine have already taken advantage of private shakedown events to give their new 2026 models some track time. These early runs are crucial for gathering initial data ahead of the full week of testing that kicks off on January 26, where the circuit will be occupied for an entire week.
During this Barcelona test, teams are permitted to utilize only three out of the available five days for unrestricted car running, and McLaren has opted to forego the opening day. Instead, they are focusing on retrieving their car from AVL facilities in Graz, Austria, where the MCL40 has recently undergone rigorous performance assessments on the engineering company's dynamometer.
At the upcoming Barcelona test, the car will sport a testing livery, which precedes the official unveiling of the team's complete livery planned for February 9. Initially, McLaren will conduct a shakedown of the vehicle before diving into their comprehensive testing agenda over the three designated days.
Team Principal Andrea Stella confirmed, "We plan to commence testing either on day two or day three. Therefore, we will not be engaging in any testing on day one, as we want to maximize our development time."
Stella elaborated on the reasoning behind this decision, noting the rapidly evolving nature of the 2026 design process, which allows McLaren to uncover performance enhancements almost daily. This necessity for continual improvement influenced their choice to delay track activities until closer to the testing sessions.
While acknowledging that rival teams who have completed their shakedowns might gain an advantage by starting testing sooner, Stella expressed concerns about the potential trade-offs that could arise from prematurely committing to specific design choices that may not be fully optimized.
"In fact, this was always intended to be our Plan A—holding off on running initially," he added. "Given the extensive changes involved, we don't need to be the first on the track. Our focus is on allowing for maximum development time because each day dedicated to design yields incremental performance improvements.
"This also presents a dilemma: while being among the early teams on track can provide reassurance about what you need to know quickly, it can also lead to premature commitments in design and realization of the car."
He highlighted the balancing act between development time and ultimate performance, emphasizing that updates are likely to be issued for nearly every car leading up to the testing period and the first race. Ultimately, McLaren believed it was vital to begin the season with the most competitive package possible. Therefore, they pushed their timeline to the brink—but within a manageable framework. "We are on schedule to start testing on day two without feeling any pressure to rush preparations for day one."
