Mercedes' early edge is fading

Across the opening 11 rounds of the 2026 Formula 1 season, the pecking order among most teams has fluctuated. Mercedes has been the only consistently strong squad, coming out of the gates fast in this new technical-regulation era in terms of both car package and engine. But the performance edge it held in those early rounds has slowly dissipated as its closest rivals have introduced regular upgrades.

That developmental race will be one of the main factors that determines if any of the other teams can stop Mercedes winning the 2026 constructors' championship. And the gains being achieved are not minor improvements — it's chunks of a second at a time, putting those teams into contention for podiums and even wins. Take Ferrari in Barcelona in June, Red Bull in Austria a couple of weeks later, or McLaren in Hungary last month. All three brought upgrade packages to those weekends that pushed their drivers back into the top mix with Mercedes.

"(But) what we're seeing in 2026 is Formula 1 operating at a level that has never been the case before," McLaren team principal Andrea Stella said in Austria. "The overall gain in terms of pure performance development (is there again), but performance delivery to track is to a higher level than I've ever seen before."

The cost-cap showdown

There is one element shared between all 11 teams: they face the same cost-cap restraint. It was increased by $80million to $215m for this season to reflect the additional development work the new rules required, with the goal of creating a more level playing field by limiting spending overall.

Looking across the grid, a few strategies have emerged: race-by-race incremental upgrades, waiting to add a big package all at once, and a hybrid of the two. Some teams opted to make an early push, including Ferrari and Red Bull. Ferrari brought 32 upgrades across eight races, with its largest package coming during the Miami Grand Prix at the start of May, when 11 components were changed, followed by an eight-component upgrade in Barcelona. The most-upgraded area for Ferrari is the floor and underbody, with 11 developments. McLaren has focused on its car corners and suspension parts, with 10 such upgrades, while Red Bull has done significant work on its rear wing and main bodywork.

Ferrari's aggressive strategy was enough for Mercedes team principal Toto Wolff to raise questions about the Italian team's spending, particularly given Mercedes has introduced just one major upgrade package, which arrived in Canada in late May.

"We're a little bit surprised that Ferrari can throw these huge updates at the car in the way they do," Wolff said in Austria. "In my opinion, they need to be running out of cost-cap money soon, because we can't do that. We simply lack the buffer in the cost cap to be able to bring so many parts in the way they do. Hopefully, that's going to change towards the end of the season. They won't be able to bring any more parts. The logic would say that, and then we're going to come with more."

Ferrari counterpart Fred Vasseur shared his thoughts on Wolff's comments during the subsequent British GP weekend: "I found it quite ironic, coming from Toto and Mercedes. When Red Bull is developing or when Mercedes is developing, they are geniuses. When we are developing, we are cheating."

For Ferrari, it's all about getting upgrades onto the car as fast as it can. "It's better to have a couple of tenths for five races than a couple of tenths for the last two," Vasseur said. Sometimes, he added, such gains come not from a big package of new components but rather "a modification of some parts, nothing else" — remaking existing parts from lighter metal to bring significant lap-time gains.

Different strategies across the grid

Other teams are taking different approaches out of differing necessities. Aston Martin has been essentially making a B-spec car after starting the season badly, bringing 16 developments to Hungary for a big chassis upgrade to be paired with a Honda engine update once the season resumes at Zandvoort. Williams, which Aston moved ahead of in Hungary, is targeting the Azerbaijan GP for its big upgrade.

The development battle carries a degree of mystery for the teams themselves — it's only when a car hits the tarmac that they can see if on-track performance correlates with the factory data.

"You never know what someone's going to bring, and those upgrades can change," Cadillac CEO Dan Towriss said at the British GP. "As the season goes on, in theory, the change is going to become more incremental."

Ferrari has shown the power of a strong development trajectory, steadily closing the gap to just 72 points behind Mercedes with around half of the 23-event season to go. Racing Bulls, meanwhile, overtook Alpine to head the midfield with a series of successful upgrades before the summer break.

Whether the rate of development slurs will depend on where teams sit within their cost-cap restraints and when they must start focusing on their 2027 car — at which point a fresh development race will begin.

"Let's see who is investing early on next year," Red Bull team boss Laurent Mekies said in Austria, "and who is investing a bit more this year, and who has managed to somehow unlock a bit more capacity (to do both)."
