Mercedes Upgrade Warning: 'Full Benefit' Yet to Come, Says Antonelli

Kimi Antonelli has warned that Mercedes is yet to see the "full benefit" of its latest upgrade package, introduced at the Canadian Grand Prix. The young Italian won his fourth consecutive race in Montreal, extending his championship lead to 43 points, but believes cold weather masked the new parts' true performance.

Why it matters:

Mercedes' upgrade success is critical for sustaining Antonelli's title charge. If the W17's new package delivers as expected on more representative tracks, the team could solidify its position at the front. However, if gains are less than anticipated, rivals like McLaren and Red Bull may close the gap, making the upcoming races pivotal for championship momentum.

The details:

• Antonelli's view: "The package has been working, but it has been changing the balance a little bit. We're not seeing the full benefit because of the unique cold conditions in Montreal. When we go to Monaco and Barcelona, we will see much better the benefits." He emphasized that getting tires into the right window made a big difference in Canada.
• Wolff's caution: The team principal noted that Canada was "a sweet circuit" for Mercedes last year, making it "very difficult to assess" whether the upgrade is delivering as expected. He added that Monaco may not provide a clear answer either, and the team needs to continue monitoring and analyzing performance across different circuits.
• Championship context: Antonelli's fourth straight win has built a commanding lead, but Mercedes must ensure continued development to maintain momentum. The W17 has shown strong pace on specific tracks, but consistency across different circuit types remains unproven – a key question heading into Monaco and Barcelona.

What's next:

The Monaco Grand Prix this weekend will be the first real test of the upgrade's effectiveness on a low-speed, high-downforce track. Barcelona follows shortly after, offering a more balanced circuit that should reveal the package's true potential. Mercedes will be watching closely to confirm whether their recent dominance is sustainable or a product of favorable conditions. With Antonelli leading the standings, the next two races could define the team's trajectory for the rest of the season.
