McLaren arrived in 2026 as the team everyone wanted to measure themselves against. One race into the new power unit era, it’s McLaren doing the measuring — and the numbers from Melbourne weren’t flattering.
Lando Norris, defending his world title, didn’t try to dress it up after finishing fifth at Albert Park, more than 50 seconds behind George Russell. Mercedes locked out the front row and converted it into a 1-2 in the race; the next-best Mercedes-powered car was Norris’ McLaren, and even that was nowhere near close enough to pretend this is just “early-season noise”.
What’s bothered McLaren isn’t that Mercedes has a better engine — the regulations are meant to prevent that kind of customer-starvation story. It’s that Mercedes looks like it understands its own package in a way the customers simply don’t yet. And in 2026, that “understanding” is lap time.
Andrea Stella was unusually blunt in Australia, admitting that, for the first time in this partnership, McLaren feels like it’s starting a season “on the back foot” as a customer. He wasn’t talking about hardware. He was talking about the black art of making the new rules work for you: energy deployment choices, where you lift and coast, when you lean into super-clipping, and how you place your battery usage so it lands as performance rather than just numbers on a trace.
Stella said McLaren’s post-Melbourne analysis — including overlays against Mercedes and other competitors — pointed in a pretty clear direction: there’s more performance available from the Mercedes HPP unit than McLaren is currently extracting, and it isn’t obvious how to unlock it quickly.
That’s the uncomfortable bit for customer teams under a rebooted regulations set. The rules require the manufacturer to supply identical hardware and software to its customers, and the power units must be “capable of being operated in precisely the same way”. Calibrations linked to engine oil and fuel must be identical too. But there’s a canyon between “here’s the same kit” and “here’s the roadmap for how to make it sing at every corner on every circuit”.
Norris, in China, essentially confirmed McLaren is having to do the hard yards itself. McLaren and HPP talk, and Norris was keen to underline that relationship has already delivered championships — but he was equally clear that the fine detail isn’t something that gets handed over like a user manual.
“Certain things don’t need to be told,” Norris said, in a line that will resonate across every customer garage up and down the pitlane. In other words: everyone protects their little advantages, and under these regulations “knowledge” is one of the most valuable currencies you can own.
There’s also a practical frustration underpinning all of this. Norris revealed McLaren didn’t get the latest-spec power unit until the start of the Australian Grand Prix weekend, meaning it ran a previous-spec unit in testing. That might be defensible on a spreadsheet somewhere, but in a year when the sport has effectively hit reset, it’s the kind of delay that can snowball. You arrive at round one still learning what the factory already knew months ago.
Norris’ ask is simple: be better prepared. Not because he thinks Mercedes is playing games — he explicitly dismissed the idea that McLaren is being short-changed — but because “finding out things along the way” is an unforgiving way to start a title defence.
That context matters when you rewind to Toto Wolff’s winter comments about wanting to reduce Mercedes’ customer programme by at least one team, and his “enemy in the house” framing of McLaren. Wolff’s position was straightforward: HPP exists to win titles with the works team. Customer success, as he put it, isn’t what anyone inside Mercedes is there for.
It’s exactly the kind of honesty that makes sense politically and commercially — and exactly the kind of honesty that should make a customer team wary of assuming they’ll ever get more than the contractual minimum.
Norris, though, has taken a notably pragmatic line. McLaren “gets everything that we want”, he insisted. The deficit in Melbourne, in his view, wasn’t evidence of Mercedes holding anything back. It was evidence that McLaren hadn’t yet done enough to exploit what it already has.
That’s the sting: if the gap is knowledge-led rather than hardware-led, it’s both fixable and brutal. Fixable, because it’s about process, simulation tools, correlation and trackside decision-making. Brutal, because Mercedes will keep learning too — and because the first races of a new era are when the easy lap time gets banked. Miss it and you’re spending the season chasing performance that your rivals already converted into points.
Shanghai, at least, offers McLaren a chance to steady the mood. Norris expects it to be closer, partly because Melbourne is one of the tougher venues for energy recovery, with more compromises in lift-and-coast and deployment. China is “simpler” in that sense, and Norris believes the learning from Albert Park should translate into a more competitive weekend even if McLaren were to return there now.
Still, he didn’t pretend it’s only about the power unit. The car needs improving too — that’s the longer-term workstream, as he framed it — but the immediate ambition is clear: get McLaren’s operational understanding of the Mercedes unit closer to the works team’s level, quickly enough that 2026 doesn’t become a season of regretful post-mortems about what got away in March.
For a reigning champion, it’s an unfamiliar posture: not defending a position of strength, but defending while learning in public. And in this new era, the teams that learn fastest will be the ones still smiling when the easy gains are gone.
