For the second year in a row, Carlos Sainz Jnr set the quickest lap time of any driver in pre-season testing.
He’s changed teams since then, so the bragging rights for fastest overall time go to Williams. But as we all know, headline testing times don’t reveal who is fast and who isn’t. For the same reason, constructors’ champions McLaren are unlikely to be alarmed they only set the fifth-fastest time.Three days of running in Bahrain have yielded some noteworthy data, however.
2025 pre-season lap times
The most striking feature of the teams’ lap times this year is how close they are. This appears to support the view that the field would continue to tighten up in the fourth year under largely unchanged technical regulations.

2025 pre-season lap times compared to last year’s test and grand prix
Three teams stand out when comparing their lap times from this week to the test and grand prix at the same track last year.
Both these teams have indicated the opportunity offered by next year’s rules change is a particular priority for them. They appear to have begun this year with cars closely based on those they had at the end of last season. They should therefore be able to exploit their available performance more easily, which may be reflected in the times, but it remains to be seen what development potential they will have over the year ahead.
Sauber’s times also stand out for two reasons. They are the only team who lapped slower this week than they did in both the grand prix and the test last year, which is a discouraging sign. This was memorably the case for Ferrari in pre-season testing five years ago, and that team went on to endure a tough season.

2025 pre-season mileages compared to last year’s test
Despite several bizarre interruptions – including a power cut, a smashed pane of glass and a wayward bus – the 10-team field got more testing done than last year. Together they racked up 3,896 – almost 200 more than in 2024.
However there was a significant gap between those who did the most and the least. Mercedes, the busiest team of all, covered 50% more running than rivals Red Bull. That 833-kilometre difference is the same as more than two grands prix.

Any driver like Ocon who was adjusting to new teams would have welcomed that kind of mileage. Lewis Hamilton, however, did almost 100 fewer laps in his Ferrari, after his final day in the car came to an early end due to an apparent technical problem.
The only drivers who covered fewer laps than he did were the Red Bull pair and Lance Stroll. The latter had to sit out most of the final day as he was unwell.

@keith – there’s a slight typo in the last time sheet… You’ve mentioned “Ferrari” as the engine supplier for Carlos’ Williams.
Thank you for the insightful article.

I’m quite looking forward to this season, naturally this will be the closest battle for the championships in this regulation era. That alone makes me wish the 2026 regs would not come into play for a few more years. The fans deserve to see the battles which come from convergence; not least because it’s natural, unlike the artificial rules the commission is pushing.

It might be the closest, but 2024 was so unusually competitive that the most likely outcome is reversion to the mean
I.e. we will probably find fewer drivers win 2 races each this year, and we will probably find not so many teams are close at the front… simply because last year was an outlier.

Congratulations to Williams! The rank and file at Williams must have gone into Testing wondering why James was so demanding, why this and that had to change, and why he employed Carlos, and then they leave Testing with the fastest lap time. This is a huge moral boost.

Why would anyone question the hiring of Sainz?

I’m guessing Williams have to pay a lot to employ Carlos, and that he is a demanding driver. Carlos knows what you need in a car which gives it a chance of winning races, and he would have realised what was missing or under-performing in the Williams car. So Williams have to spend time and money listening to Carlos, trying to understand his complaint, then trying to fix it so their car becomes “winning pedigree”. I have seen many good drivers go to lesser teams and lose their ambition. Williams could easily have gotten a cheaper driver, and they could have also fallen into the trap of not listening to Carlos because of apathy. Instead Williams are committing money to trying to bring their car up to the standard Carlos wants.

Amazing start for Williams – I imagine Albon is very closely watching the traces to understand how Carlos beat him
The season is looking fantastic

We all know how little testing and practice times matter, but seeing sainz on top makes me really wonder if he will still have a top car after all; can’t say anything until q1 at the very least, but IF williams turned out to be a top car, it’d be nice, since sainz didn’t deserve to end up in a midfield\bottom car.

It’d easily be the best story of the season. McLaren are miles ahead of anyone, but if we suspended disbelief and imagined Sainz won the WDC it’d likely be the most legendary F1 story ever. Alas, I think the most we can hope for is that he finishes 9th (maybe 8th due to Lawson and if the RBR is as weak as it appears), but that wouldn’t be half bad.
