Williams leapt from ninth place with 17 points in 2024 to P5 in the 2025 Constructors’ Championship with 137 points. That’s a 706% increase in a single season.
The numbers tell part of the story. But I’ve been watching how Sainz actually changed this team, and it goes deeper than podiums and points.
The Thinking Driver’s Advantage
Sainz brings what I call a “thinking man’s approach” to racing. He’s quick and canny, similar to his countryman Fernando Alonso.
But here’s what makes him different: he challenges the pit wall in real-time when his read of the race is sharper than their data. This happened regularly at Ferrari, and he was proven right.
That takes extra mental capacity while driving at the limit. Most drivers can’t process race conditions and question team strategy simultaneously. Sainz can.
At Qatar, Williams entered the weekend with low expectations based on their struggles at similar circuits. Sainz delivered a podium anyway. “We nailed the race pace, the strategy, the tire management, the start, all the defending,” he said after the race.
The Integration That Actually Worked
Williams wanted Sainz badly. When a struggling team gets desperate for talent it creates risk, too much power to one driver disrupts the structure.
That didn’t happen here.
James Vowles and his leadership team are executing a multi-year plan. They wanted drivers who are fast and good team players. Sainz speaks up and pushes, but he’s smart enough to know his place. He learned that from his dad and from Alonso.
The adjustment period was gradual. No single race marked the turning point. Sainz just got stronger as he became familiar with the car and team. Things flowed more naturally.
Here’s the critical part: he found performance without taking unnecessary risks. Williams drivers crashed constantly last year because they had to overdrive a difficult car. Sainz maximized results by being smooth, not aggressive.
The Teammate Dynamic
Sainz out-qualified Alex Albon 13-10 this season. He’s been even better than Albon, which is significant considering Alex brought impressive results over the past two years despite the car’s limitations.
But there’s no friction.
Both drivers push each other. Albon was the established Williams driver everyone knew and admired. Sainz came in as the outsider and race winner. That dynamic elevated the entire team’s performance.
Vowles emphasized that “Albon’s performance across the season is why we’ve secured fifth in the constructors’ championship.” The collaboration works because both drivers deliver without drama or political intrigue.
Why His Career Path Makes Him More Valuable
Most drivers who move around as much as Sainz (Toro Rosso, Renault, McLaren, Ferrari, and now Williams) get labeled as journeymen without a home.
Sainz’s path made him more valuable, not less.
He’s demonstrated he can be paired with Verstappen, Hülkenberg, Norris, Leclerc, or Albon and do well. His adaptability from jumping between teams became his superpower. He takes what’s given to him and figures out how to drive it best.
That intelligence benefits the team beyond just lap times. They can see his data and analyze his approach. His technical feedback accelerates car development.
Sainz stated that “2025 has exceeded my expectations in terms of car performance and what the team is capable of doing.” He added that if someone told him when he signed in summer 2024 that there would be podiums, P5 in constructors, and regular competitiveness, he would have signed even quicker.
What Other Teams Should Learn
Overlooked drivers—those without the accolades of a Verstappen, Leclerc, or Hamilton—can bring tremendous value to a team.
A strong work ethic, sharp mind, and team-oriented approach maximize results. This has been a hallmark of Sainz’s career. Every team he’s joined has improved. Not every driver can say that.
He brings more than outright speed. He brings championship-level execution, strategic thinking, and the ability to deliver in high-pressure situations without burning bridges.
Williams broke their four-year podium drought at Baku. Sainz became the first Williams driver since Felipe Massa and Valtteri Bottas in 2015 to take multiple podiums in a single year.
“This is my life project,” Sainz declared. “If I manage to bring Williams back to being competitive and winning races, it’s everything that I care about.”
Looking Toward 2026
Williams is targeting P4 unless Ferrari or Red Bull bungle the new regulations. If the Mercedes power unit lives up to the rumors, teams like Williams hold an advantage.
What makes the difference is getting strategy calls right consistently, what enabled Red Bull to maximize results this year. If Williams avoids tactical errors like McLaren’s recent mistakes and nails the overall car design, they’re set for strong results.
Vowles said P5 “would have been a dream come true just 12 months ago when we were languishing in ninth.” The second podium at Qatar, on a track that was nearly their worst last year, proved the transformation is real.
Sainz has accelerated Williams’ timeline beyond what anyone expected for 2025. The team was always planning to make 2026 their focus. Their strong 2025 results were supposed to be a bonus.
Instead, Sainz proved once again he’s a catalyst for improvement. Not through hype or drama, but through intelligence, adaptability, and the rare ability to make every team he joins better.
