Cadillac Prioritizes Debugging Over Pace as Barcelona Testing Resumes

Cadillac is set to resume its testing program in Barcelona on Wednesday after skipping Tuesday to address technical gremlins. Following a debut day where Sergio Perez completed just 11 laps due to "a lot of issues," the American squad is prioritizing system reliability and team integration over outright performance.

Why it matters:

As a brand-new entry with modest expectations for 2026, Cadillac’s primary objective is building a functional foundation rather than chasing lap times. With the new regulations representing the "biggest change" in drivers' careers, the team needs to maximize this shakedown period to understand its own machinery and establish operational workflows before the season begins.

The details:

• Monday's Progress: Valtteri Bottas enjoyed a solid morning with 33 laps, but the afternoon session was hampered by issues that limited Perez to just 11 tours.
• Strategic Debugging: Team principal Graeme Lowdon clarified that the team could have pushed for more laps but chose to stop and solve problems immediately. This "de-bugging" phase is considered more valuable than mileage right now.
• Performance Gap: The team finished 6.5 seconds off the pace, but this is irrelevant given their current stage of development and expectations to be at the back of the grid.
• Regulation Shock: Perez described the new power unit and car characteristics as "massively different" from previous F1 machinery, requiring a significant adjustment period for the drivers.

What's next:

Cadillac will continue its methodical approach for the rest of the week in Barcelona before heading to Bahrain for two additional tests. The team remains focused on ticking off system checks and ensuring reliability, aiming to arrive in Bahrain with a car that is ready to run consistently rather than competitively.
