Laurent Mekies knows exactly what he’s trading.
With the 2026 rulebook about to flip Formula 1 on its head, Red Bull has kept the tap open on RB21 development deep into the run-in. McLaren has gone the other way, parking late-season updates to pour everything into next year’s clean-sheet era. Two title protagonists, two very different bets.
Mekies, running Red Bull’s push from the pit wall, isn’t hiding from the bill that will arrive in January. He just thinks the return is bigger. The team has been drip-feeding small but telling tweaks onto Verstappen’s RB21, and the car has inched forward at precisely the point the title fight tightened against McLaren’s Lando Norris and Oscar Piastri.
“We’re not doing it blindly,” Mekies said after Mexico City. “There’s a cost to 2026, yes, but for us the trade is a net gain.” In other words: spend now, learn now, cash it in later.
The logic is simple enough. Red Bull says the real prize isn’t only here-and-now performance, it’s validation. The team wants hard evidence that its wind tunnel and CFD tools are pointing in the right direction and that the way it interprets those numbers translates faithfully to the racetrack. That correlation loop is gold dust heading into a rules reset. If the ideas you trust produce lap time in 2025, you sleep better building the RB22 for 2026 with the same tools and people.
“It’s important we get to the bottom of what the car’s telling us,” Mekies added. “Even if next year’s regulations are radically different, you still rely on the same methodology. We want confidence in the winter that our way of developing will deliver.”
It’s an interesting contrast with McLaren. Andrea Stella has been clear: their MCL39 hit diminishing returns. To find another point of aero efficiency takes weeks; on the 2026 car, they say they’re finding chunks every seven days. That, plus the pressure of reduced wind tunnel and CFD time at the front of the field, pushed them to make an early call. As Stella put it in Mexico, if they’d kept chasing 2025 gains, “the 2026 project would be heavily compromised.”
There’s competitive theatre baked into these positions. McLaren led the season’s first half with authority; Red Bull looked scruffier than we’ve become used to. As the year wore on, Verstappen chipped away, the RB21 cleaned up, and the hole shrank. You can call it a philosophy split or simply two teams reading their own data and making different bets. Either way, it’s added a fascinating strategic layer to a title race that’s been more knife-edge than many expected.
Make no mistake, Red Bull knows it’s playing with matches. Every extra hour spent understanding the RB21 is an hour you can’t spend finessing early RB22 concepts for the new power unit/aero package arriving in 2026. There’s a reason most teams have hit the off switch on upgrades. But if your winter is built on shaky assumptions, you burn time later. Mekies’ view is that clearing up questions now will save more time than it costs.
The nuance here is worth underlining. This isn’t Red Bull pretending 2026 won’t bite. It’s them saying they’ve found real performance in the late-season changes, and—critically—that those changes confirm their process works. That’s the sort of green light technical groups crave. A few hundreds here, a tenth there, and a big tick in the “our tools are honest” column.
McLaren, on the other hand, sees less value in fighting for incremental steps when the lap-time frontier moves next year. They’ve also felt the squeeze of development restrictions that come with success. When Stella talks about “being realistic,” it’s not defeatism; it’s a ruthlessly pragmatic read of where the next second is hiding.
Who’s right? We’ll find out in March. If Red Bull rolls into the 2026 opener a touch undercooked, these November gains will be thrown back at them. If McLaren’s early-doors package is on rails, Stella’s caution will look savvy. But if Verstappen’s late-year surge flips the championship while Red Bull also turns up competitive out of the gates next season, Mekies’ gamble starts to look like a masterstroke.
What we do know, per the 2025 picture, is that Verstappen has dragged himself back into realistic contention against Norris and Piastri. Titles are won on margins and momentum as much as spreadsheets. Red Bull’s choice is about both: performance on Sundays now, and conviction about the tools that’ll decide 2026.
So yes, there’s a price. Red Bull’s decided it’s a bill worth paying. McLaren’s decided it isn’t. Whichever way you slice it, the final chapters of 2025 just got more tactical—and 2026 already has a subplot before a wheel turns.
