Piastri: FIA tweaks could help McLaren close gap to Mercedes

Oscar Piastri suggests recent FIA regulation adjustments could help McLaren narrow its performance deficit to dominant Mercedes, though he cautions the primary gap remains in chassis and downforce. The Australian driver pointed to his strong podium finish in Japan as proof McLaren can maximize its package, even while acknowledging Mercedes' current superior understanding of the complex 2026 power unit regulations.

Why it matters:

Mercedes has set the benchmark in the early phase of the 2026 season, making any potential shift in the competitive order significant. Piastri's assessment provides a realistic gauge of McLaren's position; while hopeful for gains from the rule tweaks, he identifies the core challenge as car performance, not just engine mapping. This highlights the multi-faceted battle teams face under the new regulations.

The details:

• Cautious Optimism on Rules: Piastri expressed a measured view, stating that while the FIA tweaks might help, Mercedes currently has a "better understanding of the power unit and how to get the most out of it."
• Japan as a Benchmark: He cited his Japanese Grand Prix weekend, where he finished on the podium and held off Mercedes drivers for extended periods, as evidence his team executed perfectly. He noted teammate Lando Norris had a compromised weekend, but his side of the garage maximized their car's potential.
• Identifying the Real Deficit: The driver clarified that the gap in Japan was not primarily due to the power unit but because "our car wasn’t as good as theirs." He emphasized McLaren remains "a fair way behind on, you know, just downforce and performance from the chassis."
• Mercedes Not Unbeatable: Despite their strong form, Piastri warned that Mercedes is "far from untouchable," drawing encouragement from his ability to race competitively against them in Japan.

What's next:

All eyes will be on the Miami Grand Prix, where the FIA's regulation changes come into effect. Piastri expects the gap in power unit understanding to "close a little bit" as the season progresses. The true test will be whether McLaren can translate the regulatory adjustments and ongoing development into tangible lap time to consistently challenge the Silver Arrows, turning podium contention into victory contention.
