Andrea Kimi Antonelli, the rising star and new Mercedes Formula 1 recruit, is gearing up for his first on-track outing of the 2025 season, piloting the team’s 2020 W11 car at Jerez this week. The test, designed to further prepare the young Italian for his rookie campaign, comes amid a significant tightening of F1’s testing regulations, forcing teams to be more strategic about how they allocate testing opportunities.
Why the W11?
The W11, Mercedes’ title-winning car from 2020, holds a special place in the team’s history. It powered Lewis Hamilton to his record-equalling seventh Drivers’ Championship and delivered Mercedes its seventh consecutive Constructors’ title. While the car is from an era with vastly different regulations, it remains a benchmark of engineering excellence.
Antonelli’s upcoming test under the Testing Historic Cars (THC) framework reflects the FIA’s revised restrictions on in-season testing. The W11, being the latest car eligible under the THC guidelines, will provide Antonelli with valuable track time without consuming any of the team’s Testing Previous Cars (TPC) allocation for newer machinery.
Revised Testing Rules and Their Impact
The FIA’s adjustments to the TPC rules now cap teams at 20 days of testing with two-year-old cars per year, while race drivers are limited to 1,000 kilometers of TPC mileage annually. This change came after Red Bull exploited the previous rules by running Max Verstappen in the 2022 RB18 mid-season in 2024 to compare data and improve the RB20’s performance.
The move sparked controversy, with Ferrari accusing Red Bull of using the session for development rather than driver acclimatization. These concerns prompted the FIA to tighten regulations, ensuring such tests are not used as loopholes for technical gains.
Mercedes, therefore, opted to conserve its TPC days for later in the season when more actionable data could be gathered. By using the W11 at Jerez, the team is making the most of THC provisions while giving Antonelli the chance to build confidence in a high-performance F1 car.
What This Means for Antonelli
For the 19-year-old Antonelli, this test represents another step in his accelerated journey to Formula 1. Despite already gaining extensive experience in the W13 and W14 during his development program, the Jerez outing will be crucial for refining his understanding of Mercedes’ operational setup and enhancing his adaptability.
“Kimi has shown tremendous growth through our development program, and this test is a continuation of his preparation for the challenges ahead,” said Toto Wolff, Mercedes’ team principal.
While the W11’s characteristics differ from the 2025 W16 he will race this year, the session will allow Antonelli to focus on fundamental skills such as high-speed car control, race simulation runs, and working closely with the engineering team.
Looking Ahead
With Antonelli replacing the Ferrari-bound Lewis Hamilton, expectations are high for the Italian prodigy. Testing the W11 is just the beginning of a season-long learning curve that will see him adapt to the challenges of F1’s ground-effect era. For Mercedes, this strategic use of THC testing underscores the team’s long-term vision to nurture their next potential champion while adhering to the sport’s evolving regulations.
As Antonelli takes the wheel of a car synonymous with dominance, fans and insiders alike will be watching closely to see if this future star can carry Mercedes back to the top in the years to come.
