Sainz believes Williams needs to replicate Aston's significant progress.

      "We should be capable of achieving the same."

      Carlos Sainz stated that Williams now needs to demonstrate it can replicate the remarkable transformation that Aston Martin experienced in Hungary after Fernando Alonso made a surprising leap from the back of the grid with the team’s significantly modified ’B’ car. Aston Martin arrived at the Hungaroring with a completely overhauled chassis, after spending much of the season towards the back, and Alonso managed to reach Q2 as the new setup resulted in a significant boost in downforce.

      "I believe that as a team, rather than viewing Aston Martin’s situation with worry, we should approach it with motivation and excitement," Sainz conveyed to Spanish journalists. "They’ve demonstrated that a team that had one of the least effective downforce setups on the grid has, from one race to another, achieved the best downforce in the midfield."

      "The fact that a midfield team with similar resources and capabilities as us has accomplished this should motivate us to see that if we are on par with them, we should also be able to do it."

      Williams' own lighter ’B’ specification won’t be ready until Baku, but Sainz has expressed skepticism about its adequacy. "Due to our capacity, we need to implement these changes on next year’s car since the Baku upgrade was planned four to five months ago," he explained. "So, by the time we reach the Baku upgrade, any additional enhancements you wish to make to the car will already be out of reach. They will need to be added to next year's vehicle."

      "After Baku, there won't be anything else, and I believe the team should concentrate on the car for next year."

      Regarding Alonso, he asserted that Aston's breakthrough is more important than simply reaching Q2, as it indicates that the team led by Adrian Newey has finally addressed its ongoing correlation issues. "More significant than Q2 is the fact that we’ve taken a completely new car to a race and proven that it functions," he stated. "We didn't always have that assurance due to correlation problems. The best news is that it appears the issues have been understood, and now we just need time to get everything organized."

      Alonso mentioned that the new car has also highlighted where Aston Martin still needs improvements. "We know exactly what steps to take," said the nearly 45-year-old. "This progress enables us to calculate our requirements in terms of chassis and engine. Until now, we were missing crucial tenths of seconds on both fronts, creating a rather challenging situation."

      However, Alonso acknowledged that the Honda power unit continues to be a shortcoming. "We need a bit more engine power," he noted, with Honda planning to test its revised power unit during a filming day at the Hungaroring next week, ahead of its race debut in Zandvoort.
