Piastri's limited running highlights Pirelli's 2027 tire test at Nürburgring

Oscar Piastri's Pirelli tire test at the Nürburgring was cut short by a technical issue on his McLaren, while George Russell completed a full program for Mercedes as Formula 1 returned to the iconic German circuit for the first time since 2020. The 'blind' test, focused on gathering data for 2027 tire constructions, saw promising initial results despite the wet track conditions that delayed the start of running.

Why it matters:

These dedicated Pirelli tests are crucial for shaping the future technical regulations and performance of Formula 1. The data collected directly informs the development of the 2027 tire compounds, which will need to suit new car regulations and play a key role in the championship's competitive balance. For teams, it's a rare opportunity to run their current cars outside of a race weekend, providing valuable track time and operational practice, even if they cannot test performance upgrades.

The details:

• The test was conducted under wet initial conditions, with drivers starting on intermediate tires after overnight rain before switching to the scheduled slick tire program.
• Oscar Piastri and George Russell began the day with eight-lap runs to evaluate various construction variants of the C3 compound tire.
• Piastri's running was severely limited after his MCL38 developed a technical problem around lunchtime, confining him to the garage for most of the afternoon. He completed only 65 laps with a best time of 1:35.096.
• In contrast, George Russell enjoyed a trouble-free day, managing 127 laps for Mercedes with a best time of 1:33.899, allowing Pirelli to conduct valuable longer stints with the test tires.
• The test is conducted under strict 'blind' conditions, meaning drivers are not told which specific tire compound they are testing to ensure unbiased feedback.

What's next:

The test program continues at the Nürburgring for a second day, with the driving duties switching to the teammates of Tuesday's participants.

• Lando Norris will take over the McLaren MCL38 from Oscar Piastri.
• Mercedes junior driver Kimi Antonelli will step into the W15, replacing George Russell.
• This rotation allows Pirelli to gather a wider set of driver feedback and gives Antonelli another valuable opportunity in a current-spec Formula 1 car ahead of his anticipated 2025 debut.
