Andrea Kimi Antonelli believes Mercedes is finally beginning to unlock the potential of its upgraded W17 after dominating the 2026 United States Grand Prix, although problems with front-wheel locking in slower corners remain unresolved. The Italian secured pole position and converted it into a commanding victory at the Circuit of The Americas, while teammate George Russell finished eighth, more than 50 seconds behind.
The contrasting performances highlighted just how effectively Andrea Kimi Antonelli has adapted to Mercedes’ latest development package. Having previously insisted that he would continue using the upgraded car until he could extract its full potential, the championship leader delivered the clearest indication yet in Austin that the team’s recent technical changes are beginning to produce the expected improvements.
Kimi Antonelli finally unlocks Mercedes W17 upgrades at Austin
Mercedes’ latest development programme has not been straightforward. The upgraded W17 initially proved difficult to optimise, with changes to the car’s aerodynamic characteristics creating challenges for both drivers. However, the United States Grand Prix offered an encouraging first glimpse of the performance available from the latest specification.
Andrea Kimi Antonelli controlled the Austin weekend, securing pole position before winning Sunday’s race by a substantial margin. The Italian completed the Grand Prix with a single pit stop, demonstrating the combination of outright speed and tyre management that allowed Mercedes to maximise its performance.
George Russell experienced a very different race. The British driver finished eighth and crossed the line more than 50 seconds behind his teammate, a striking difference considering that both were driving for the same team.
The result reinforced the contrast between Andrea Kimi Antonelli’s ability to extract performance from the updated package and the difficulties George Russell encountered in Austin. It also provided Mercedes with important evidence that its development direction could deliver competitive gains when the car operates within the correct setup window.
The team is still working to understand the revised characteristics of the W17, particularly after its upgrades altered the aerodynamic balance and made the car more sensitive to setup changes. Mercedes’ latest progress suggests that some of those difficulties can be mitigated, even if the operating window remains demanding.
Mercedes upgrades improve high-speed performance but front locking remains
Speaking during the post-race press conference, Andrea Kimi Antonelli explained where the upgraded Mercedes is beginning to deliver positive results and which areas still require further development.
“In some respects, I would say this package still hasn’t given us as much as we expected, but in others it is delivering very good results,” Andrea Kimi Antonelli explained.
“In the high- and medium-speed corners, the car is very competitive. The balance is good. We still have some difficulties at low speeds because of front-wheel locking. Overall, I feel that the package is finally starting to deliver. We’re beginning to see the results and improvements coming from it.”
The Italian’s assessment identifies a clear difference between the W17’s behaviour through faster sections and its performance in slower corners. In medium- and high-speed conditions, the updated car now offers a competitive balance that allows Andrea Kimi Antonelli to attack with confidence.
Low-speed corners remain more problematic, particularly under braking, where the tendency to lock the front wheels can compromise corner entry. This makes it harder to maintain a consistent balance and extract the same level of performance throughout a lap.
Nevertheless, the progress demonstrated in Austin represents an important development for Mercedes. After struggling to fully understand the characteristics introduced by its latest aerodynamic updates, the team appears to be gaining a clearer understanding of how to make the package work effectively.
Mercedes still waiting for ADUO power unit upgrade
The version of the Mercedes W17 used in Austin also offered an indication of the car’s potential before the introduction of the power unit incorporating the ADUO-related developments. That remains the outstanding element of the team’s updated technical package.
For now, Mercedes’ progress has come from extracting more performance from its existing configuration, particularly through the faster corners and improved overall balance. The Austin weekend demonstrated that the aerodynamic updates have genuine potential, even though further refinement is required to address the remaining low-speed weaknesses.
Andrea Kimi Antonelli’s dominant performance therefore represents more than another victory in an exceptional season. It suggests that Mercedes is finally beginning to understand how to maximise its revised W17, providing encouraging signs for the remaining races of the 2026 championship.
With the Italian increasingly comfortable in the upgraded car, Mercedes’ immediate challenge is to eliminate the remaining front-locking difficulties and make the improved performance accessible more consistently across different circuit characteristics.
