After four seasons of the ground-effect era, 2026 promises a complete reset of the field. One of the biggest questions heading into next year is which ‘midfield’ team could interrupt business as usual at the front.
Mercedes, Red Bull, Ferrari and McLaren have had a firm grip at the front of Formula 1. In 2026, however, there is a real chance they could slide down the pecking order.
More than any of the outside contenders, Williams are poised to make an impact.

Sainz confident Williams are on “upward trajectory”
The last few weeks have seen a flurry of discussion and analysis concerning F1 2026.
Scrutiny over an engine solution being developed by Mercedes and Red Bull is the freshest story of the winter break. Crucially, it is understood that the FIA have given the green light to the solution of these two manufacturers.
Whilst exact figures are impossible to generate, the consensus is that this innovation could be worth a few tenths. Of course, this is good news for Red Bull and Mercedes.
Beyond this, however, the FIA’s verdict is hugely consequential for Williams.
The Grove-based operation were proactive in the 2024 season when opting to begin 2025 development early. Williams did this to be able to focus on the 2026 cars from January 1st this year.
This means, excluding a major oversight, Williams should be in a good place with their aerodynamic oversight. Indeed, team principal James Vowles has confirmed they are comfortably on schedule for pre-season testing and round one.
Amidst this backdrop, it can hardly be a surprise that Carlos Sainz is optimistic:
“The team is on an upward trajectory, and it’s fundamental to continue that trajectory. It’s important to keep showing progress, to not stall that progress that we are showing.
“Having said that, with such a big change of regulations, that progress might look different next year. Because it’s going to be so unpredictable to know where everyone’s going to be – but I trust what the team is doing.
“I trust all the efforts that we’ve been putting into next year’s car, through all the simulator sessions and all the development work.
“I’m feeling positive. I’m relatively happy and confident about it, but with the impossibility to say more than – ‘I don’t know where we’re going to be’.”

Delivering on higher expectations
For the best part of twelve months, Williams have been in unfamiliar territory. This year’s 5th place constructors finish, with two podiums along the way, represents the team’s best campaign in a decade.
More impressively, this was accomplished without introducing any meaningful upgrades.
Consistent with the strategy set in motion during the early months of 2024, Williams were in a position to focus on the 2026 cars from the very beginning of this year. As a bonus, they still enjoyed a very strong year in the midfield.
Still, there is a very big leap from the midfield to the front. McLaren, which itself was a sleeping giant, is the only team to sustainably make this jump in recent years.
For Williams, therefore, the challenge is to prove their bold resource allocation pays dividends for 2026.
