Mercedes introduced their second major package of the season in Malaysia, but the new parts quickly brought unexpected difficulties for the team. According to FormulaUno.it, this forced a weekend of direct comparison between the two configurations at Singapore to get to the bottom of the data. With the championship battle nearly settled due to their earlier dominance, the spotlight remains firmly on the relentless development race across the grid. Mercedes deputy technical director Simone Resta explained that this season has been an intense learning curve with entirely new regulations touching tyres, aerodynamics, chassis rules, power units, and energy management.
Reflecting on the competitive order, Resta noted that while his squad started slightly ahead, rivals have successfully closed the gap and occasionally outpaced them. McLaren proved formidable before and after the summer break, while Red Bull mounted a strong recovery after a difficult start. Speaking on the decision to bring the new components to Sepang, Resta defended the timing by stating they always aim to deploy developments as early as possible to maximize their lifespan. Unfortunately, the Malaysian circuit proved to be an extreme outlier with unique asphalt, variable weather, and massive tyre degradation.
While the data showed higher downforce as intended, the team failed to see the expected performance gains on track in those specific conditions. This prompted George to step up as a team player, making himself available for testing in Singapore to help verify the parts. Resta admitted that the extra load did not translate evenly across all operating conditions, ultimately altering the car's balance. The front end proved sharper than anticipated, requiring time to recentre the car's operating window—a task made much harder during a compressed Sprint weekend.
Looking ahead to Austin, Resta pointed out the contrasting demands of the upcoming American venue, featuring a fast first sector, a long straight, and bumpy, low-speed sections that test tyre wear and cooling. Finally, addressing the much-discussed macarena wing seen on rival machines, Resta revealed that Mercedes actually studied the concept on their drawing boards more than a year ago. While the design successfully cuts drag when opened, it also sacrifices downforce, leading the team to conclude back then that the compromise was not worth the investment in development and production. However, that verdict is not necessarily final, as the squad remains open to re-evaluating rival solutions moving forward.
