Mercedes' extraordinary F1 title fight claim

Mercedes says it can't respond to McLaren’s Formula 1 resurgence with an urgent upgrade because it hasn’t “got the money” to put extra developments on its car.

Lando Norris delivered his second consecutive victory of the season for McLaren in the Dutch Grand Prix on Sunday as his pace and better tyre management allowed him to overhaul early race leader Kimi Antonelli.

The major step that a two-stage upgrade from McLaren over the Hungarian and Dutch Grands Prix unleashed has caught Mercedes by surprise – and left championship leader Antonelli convinced his squad no longer has the fastest car.

Such a scenario would typically trigger a move to fast-track upgrades to help get Mercedes back to the front.

However, team boss Toto Wolff has suggested that his outfit cannot divert from the strategy it has employed since the start of the campaign to spread out its developments – as it does not have the leeway under the cost cap to bring many changes through.

“We haven't got the money to put developments on the car,” he said.

“I said it before, we are trying to evenly split that through the season, based on our calculations of when we can bring the biggest updates and optimising the championship points. We just can't do what we can't do.”

Mercedes has been much less aggressive than its rivals since the start of the year with its development spending.

It has not had a major upgrade since the Canadian Grand Prix and elected against joining its closest rivals in bringing any major new parts to the Dutch Grand Prix.

Based on the official FIA figures for declared upgrades over 2026, Mercedes is well behind when it comes to the number it has brought.

Ferrari has introduced 40 new components, Red Bull and McLaren 38, while Mercedes has introduced just 24.

However, those basic numbers do not tell the full story of how much spending has been done on development, as a new floor, for example, costs a lot more than a mirror shroud.

A weighted analysis giving a cost grade for each new component puts Red Bull at the top of the leading four teams, just ahead of McLaren, with Ferrari third and Mercedes quite a bit adrift.

It is not clear why, after being so conservative with its upgrades, Mercedes does not have the same headroom as other teams for extra development spending.

One theory could be that it invested more into the 2026 project early on in the hope of building up such an advantage in the championship that it did not need to spend much on development later on and rivals were put off wasting money on a title they could not win.

But any hopes of capitalising on its pace and putting the championship out of reach of its rivals were derailed by early-season reliability woes that have kept Ferrari, and now McLaren, in touch.

When asked by The Race about whether early spending explained why Mercedes did not appear to have the same capabilities as other teams who have brought more, Wolff was not convinced.

“Did we spend too much at the beginning in the initial development? I don't think so,” he said.

“I just think we're an organisation that has a certain size and infrastructure. And, you know, in that respect, we had a really quick car.

“We left between 50 and 100 points on the table with reliability issues and that would have given us a little bit more of a gap than we have today.

“Other than that, we're just continuing to execute what the plan was and what the financial realities mean for us.” 

Speaking before the summer break, Mercedes deputy team principal Bradley Lord said that the squad had plenty of development potential coming through the system – it was just a question of when items were brought to the track.

“There's a decent amount of performance working its way through the production machinery at the moment, that will start coming to the car from the races after shutdown.”

McLaren sceptical

McLaren is not convinced that Mercedes is on the back foot when it comes to cost cap limits, and thinks it has more freedom to bring upgrades than it is suggesting.

This is especially true with an extra cost cap allowance, of two lots of $3 million, that has been added to the regulations aimed at helping teams adjust to the new power unit rules for 2027 and beyond.

Asked by The Race about Wolff’s remarks suggesting it was on the backfoot with spending, McLaren team principal Andrea Stella said: “I would like to believe you, but I actually don't believe you. I don't believe it, because thanks to the 2027 power unit regulations, all teams will have an allowance in their reporting for the cost-cap.

“I'm sure that Mercedes, having seen that the rivals are kind of elevating the game, I'm sure they will now cash in on their development. Surely, it's happening on the ground.

“I'm sure the car in the windtunnel is quite a bit faster than the car they have on track, and they will want to now convert some of this potential into upgrades that make it to the real car. I'm pretty sure that they will have upgrades. Obviously, it would be good if not, but I don't even want to think it.” 

Wolff thinks that ultimately the Mercedes cost cap strategy can only be judged over the full season – as it could be that others may have to switch off spending later in the campaign while his outfit has some more headroom.

“You will see how towards the end of the season if they're going to be able to deploy as much stuff onto the car as they do now,” he said.

“Someone might have a different strategy in spending more at the beginning and in the middle of the year than towards the end.” 

Earlier in the year, Wolff annoyed Ferrari by suggesting Mercedes could not understand how the Maranello squad had been able to be so aggressive with bringing upgrades to the SF-26.

Wolff’s stance triggered a pointed response from Ferrari team principal Fred Vasseur.

"I found it quite ironic coming from Toto and Mercedes," he said. "But when Red Bull is developing or when Mercedes is developing, they are genius. When we are developing, we are cheating.”

Adding to Mercedes’ complications over the choice of timing of committing to bring an upgrade is that Antonelli will take an engine penalty at his home Italian Grand Prix – so his chances of fighting for the win there will be hampered.

Wolff added: “In theory, our calculations say that that's the best track to take it.

“Obviously, algorithms don't take the nationality into consideration. But we're here to fight for a championship and not get the most PR. So, yeah, that's what we're going to do. With George, the discussions are ongoing on if we were to take it.”
