Sainz insists Williams has failed with 2026 carCarlos Sainz has delivered his strongest criticism yet of Williams' 2026 campaign, admitting the team has "failed" with this year's car as speculation about his future continues. Carlos Sainz, British GP 2026© WilliamsThe Spaniard, increasingly linked with a move to Audi, says even the team's heavily anticipated 'B' car - set to debut at Baku - is unlikely to transform its fortunes. To be perfectly honest, not this year, Sainz told DAZN when asked if he expected a major step forward. What I do want to focus on is learning as much as possible so we can start designing next year's car in a more competitive way, because it's clear we've failed with this year's car. Sainz said Williams is now slipping well behind its midfield rivals.
