Sainz teams up with Alonso in challenging the upgrades of their competitors.

      "The disparities are vast - they’re immense."

      Carlos Sainz has shared the astonishment of fellow Spaniard Fernando Alonso regarding how the leading teams in Formula 1 continue to roll out upgrades nearly every race despite the budget cap in place. Alonso humorously remarked earlier in Austria that the top teams must have a "money machine on the minus one level in the factory" after witnessing another lengthy list of FIA upgrades. Sainz, on the other hand, is becoming increasingly frustrated with Williams' lack of progress amidst growing speculation about his future beyond 2026.

      "I agree with Fernando to some extent about what he mentioned on Thursday," he said. "We are quite surprised by the sheer number of improvements that the top teams are introducing. That’s Formula 1 for you, especially in a season where nearly every team is bringing upgrades to almost every race. The differences are vast - they’re immense."

      Williams did not introduce any new updates in Austria, where Sainz did not make it past Q1. "Once we saw the list of the other teams' upgrades for this race, it became clear to us that if we already struggled in Barcelona with the heat and fast corners, we were going to have issues here as well, given that it’s also hot and has fast corners," he remarked.

      The Spaniard highlighted two persistent weaknesses. "We're still quite heavy, and our car lacks speed in corners. So there are no secrets here—either we introduce new components, or we will continue battling for Q1." Williams is planning a significant upgrade for the upcoming weekend at Silverstone.

      "If I’m competing to make it into Q1, I hope this is the last time," he stated. "If it's not, that’s a concerning indication." He expressed his confusion over how the frontrunners manage to develop so aggressively within the financial regulations. "If it were up to us, without a budget cap, we would implement more upgrades," Sainz stated.

      "I’m unsure how the top teams manage to consistently bring upgrades. They must be more efficient under the cost cap, as they’re always introducing new components, and I don’t understand why we in the midfield can’t do the same. It’s due to being limited by the budget cap. Clearly, there’s a financial element that we’re not getting right."

      However, for the race on Sunday, Sainz acknowledged that Williams would require significant external assistance to score points. "If seven people retire, then we’ll earn some points," he chuckled. "Otherwise, we won’t."
