Sergio Perez calls for clean FP3 after data-starved Friday for Cadillac

Sergio Perez has publicly appealed for a trouble-free final practice session after Cadillac's opening day at the Australian Grand Prix was derailed by technical issues, severely limiting his track time and data collection. The Mexican driver managed only 16 laps across both Friday sessions, failing to set a timed lap in FP2 after a hydraulics issue forced him to stop on track.

Why it matters:

For a new team like Cadillac, every lap of practice is critical data for car development and setup optimization. Missing an entire session's worth of running puts Perez at a significant disadvantage for qualifying and the race, forcing the team to rely heavily on teammate Valtteri Bottas's data. This setback hampers their ability to compare setups and understand the car's behavior on a challenging circuit like Albert Park.

The details:

• Perez's Friday was compromised from the start, with a spin in FP1 followed by a terminal hydraulics issue in FP2 that brought his session to an early end.
• He completed only 14 timed laps in FP1 and failed to register a lap time in FP2, leaving the team with minimal long-run data on tire performance.
• In contrast, teammate Valtteri Bottas had a productive day, completing 52 laps and providing the team with a solid baseline of data to analyze.
• Perez identified the lack of consistent running, especially for race simulations, as the primary setback of the day.

What's next:

The pressure is now on Cadillac's mechanics to diagnose and resolve the hydraulics issue overnight to ensure Perez has a clean FP3. A smooth final practice is essential for him to gather the necessary tire data and car feel before the high-stakes qualifying session. The team's ability to recover from this technical setback will be a key test of its operational resilience early in its F1 journey.
