The 2025 F1 season saw the Mercedes W16 become a more drivable and consistent car. Here, we analyze technical developments, driver performance, and the team’s placement in the championship.
The 2025 Formula 1 season has just concluded, offering the perfect moment to review a year full of twists in the World Championship. Mercedes ended 2024 in fourth place, behind all other top teams, and in 2025, the team needed to make a decisive step forward, aiming at least for a top-3 finish in the Constructors’ Championship.
The Mercedes W16 was not designed as a revolutionary car, but rather as a vehicle focused on improving and stabilizing the strong performances shown intermittently in 2024. The Brackley team definitively abandoned extreme solutions, such as the “zero sidepod” concept seen in early 2022, concentrating instead on a wider operating window and a more predictable car for George Russell and Andrea Kimi Antonelli.
While previous seasons often saw Mercedes struggling with a difficult-to-understand car, the most notable improvement in 2025 was drivability. The W16 reacts more linearly to setup changes and puts less stress on tires, allowing longer stints and more effective race management. This did not necessarily make it the fastest car on the grid, but it allowed the team to maximize the package’s potential in many Grands Prix.
Mercedes in the first half of the 2025 season
The W16’s initial goals were clear: improve championship standing, refine tire management, and widen the car’s operating window. However, over the season, these goals were not always fully met. Mercedes showed competitiveness but also highlighted some key issues. In particular, the Brackley car suffered from a narrow operating window, especially at high temperatures, which limited its potential and slowed development progress.
To address these difficulties, Mercedes engineers introduced a new suspension at Imola, designed to improve aerodynamic efficiency in certain areas and, above all, tire management. Unfortunately, this upgrade did not deliver the expected results; instead, it worsened the W16’s overall balance. Both Russell and Antonelli struggled to understand the car’s new behavior. At the Hungarian Grand Prix, Mercedes reverted to the previous, more stable and well-tested specification, benefiting Antonelli in particular, who had faced significant adaptation challenges with the new suspension.
Second half of the championship
One of the most discussed aspects of the season was the decision to reduce W16 developments in the second half of the year. This was a clear strategic choice, aimed primarily at focusing resources on the new 2026 technical regulations. Many teams gradually shifted attention from their 2025 projects to the next-generation cars. Despite halting upgrades, Mercedes remained competitive in the final races. Russell and Antonelli demonstrated strong car control, especially in tire management, allowing the team to consolidate important results and finish second in the Constructors’ Championship.
Comparison with top F1 teams: Ferrari, Red Bull, and McLaren
In 2025, comparing Mercedes to other top teams highlights different technical philosophies and seasonal approaches. McLaren proved the most complete reference, combining raw performance, consistency, and highly effective tire management across all circuits. Unlike Mercedes, McLaren maintained high competitiveness in the second half of the season, thanks to continuous, well-integrated development. Their main strength was overall car balance, rarely compromised by track or environmental conditions.
Red Bull, while not showing the absolute dominance of previous seasons, continued to excel in aerodynamic efficiency and one-lap speed. However, the Milton Keynes car appeared more sensitive to setup changes and less consistent over race distance than in their strongest years. In this context, Mercedes often displayed greater predictability and stronger race management, although paying a performance gap under certain conditions.
Ferrari experienced a more inconsistent season. The Maranello car alternated competitive weekends with more challenging ones, showing an operating window that was not always easy to exploit. Compared to Mercedes, Ferrari often pursued a more aggressive performance approach, accepting higher variability in results. The W16, while less “explosive,” proved more consistent over the long term.
Overall, Mercedes positioned itself as the most solid team in terms of reliability and weekend management, without reaching the peak performance of McLaren or Red Bull at their best moments. Prioritizing drivability, operating window, and consistent performance allowed Brackley to capitalize on the car’s full potential, particularly in the season’s second half.
George Russell, the true Mercedes team leader
In 2025, George Russell confirmed his role as the Mercedes F1 team leader. With 2 wins and 9 podiums, the British driver finished fourth in the championship, behind Lando Norris, Max Verstappen, and Oscar Piastri. Toto Wolff expressed satisfaction with George Russell’s work, noting that the team had not always provided a car capable of consistently fighting for the top positions. This made Russell’s performance even more significant. “His performances were incredible. We didn’t always give him an easy car to drive: some weekends it was competitive from practice, on others it was very difficult. The podiums and wins show his skill. We are very lucky to have him.”
Kimi Antonelli, the Mercedes rookie
Andrea Kimi Antonelli, making his Formula 1 debut, finished the 2025 season in seventh place, securing 3 podiums and finishing behind Leclerc and Hamilton. Toto Wolff praised his first year, acknowledging inevitable highs and lows, particularly early in the season. Despite this, the team never doubted the young Italian driver’s talent. “We saw great races at the start of the season and especially at the end. We never doubted his speed and talent. I believe it was a good season and a solid base for 2026.”
Mercedes expectations for 2026
The season finale confirmed that Mercedes is heading in the right direction. The W16 provided a solid technical base, particularly in understanding car behavior and tire management. The real target, however, is clearly 2026, under the new technical regulations, where the team appears to have a clear advantage according to recent reports.
The driver pairing of George Russell, now recognized as team leader, and Andrea Kimi Antonelli, fresh from a successful rookie year, gives Mercedes a balanced lineup of experience and talent. Expectations are high for the team to return to consistent title contention, building on the lessons learned during a 2025 season that marked a turning point in their reconstruction.
