McLaren delays MCL40 shakedown amid Barcelona rain

McLaren has confirmed a further delay to the shakedown of its MCL40, opting to keep the car under wraps as adverse weather disrupts the opening of the private test at Barcelona. While rivals capitalized on early track time, the team remains in the garage waiting for a viable window to debut its 2026 machinery.

Why it matters:

In a hyper-competitive grid, early track time is gold for validating reliability and aerodynamic concepts. Missing the initial days of running forces McLaren to condense its pre-season program, potentially leaving the team with less data to fine-tune the car before the first race compared to competitors who have already banked significant mileage.

The details:

• Schedule Shift: Team principal Andrea Stella initially targeted Monday for a filming day—a 200km promotional run—to shake down the MCL40. While Mercedes and Haas logged 154 laps each on Monday, McLaren did not turn a wheel.
• Weather Impact: Rain hit the Circuit de Catalunya mid-morning on Tuesday and persisted throughout the afternoon. The team decided against running the car in its interim test livery, preferring to wait for representative conditions rather than risking a wet debut.
• Strategic Patience: With rain forecasts continuing through Wednesday, a question mark hangs over the team's immediate plans. They must decide whether to gamble on a wet track or wait for the clearer skies predicted for Thursday and Friday.

What's next:

The team is now pinning its hopes on the latter half of the week for the MCL40's on-track debut. Once the car hits the asphalt, the focus will shift immediately to reliability checks and ensuring the new package performs as expected in dry running conditions.
