Antonelli Highlights Learning Curve After First Mercedes W17 Test in Barcelona

Kimi Antonelli kicked off Mercedes' 2026 testing campaign in Barcelona, focusing on acclimatizing to the new W17 and the complexities of the updated power unit regulations. The Italian youngster emphasized the importance of mileage over outright pace, noting a distinct improvement in the car's behavior throughout the day as the team worked through their program.

Why it matters:

The 2026 regulations represent a massive shift in Formula 1 technology, particularly regarding power unit architecture. Early adaptation to these changes is vital for Mercedes to challenge for championships, as the team looks to build on the lessons learned from the previous season and maximize the potential of their new driver lineup.

The details:

• Learning Curve: Antonelli admitted that mastering the new 2026 power unit modes—including overtake and override functions—takes time. He described the driving feel as positive but noted the engine requires more active management compared to last year's specification.
• Progressive Improvement: While the morning session was about getting comfortable, the afternoon saw significant gains as the team tuned the chassis and engine. Antonelli stressed that maximizing lap count is currently the primary objective to fine-tune the package.
• Reliability Milestone: Teammate George Russell took over for the afternoon session and completed 95 laps. His feedback highlighted the surprising reliability of the new power units across the grid, a stark contrast to the turbulent introduction of the V6 Turbo era in 2014.
• Team Mileage: Mercedes completed a total of 151 laps, covering over 700 kilometers on the first day, providing a wealth of data for the engineers to analyze.

Looking Ahead:

With the season opener in Bahrain fast approaching, Antonelli feels significantly more prepared for his sophomore campaign. The team will continue to exploit the reliable running to push the performance limits of the W17 in the coming days.
