Teams' upgrade cycle narrows Mercedes' lead after Miami GP

Formula 1’s 2026 pecking order looked simple a month ago. Mercedes had won every Sunday race of the new rules era, Kimi Antonelli was piling up poles and victories, and the rest were chasing shadows. Miami complicated that picture. Mercedes still left with the Grand Prix win, but McLaren, Ferrari and Red Bull all turned up with more aggressive upgrade packages, and the gap suddenly looked a lot smaller. ### What actually changed in Miami? The big shift was developmental, not just dramatic. Sky’s rundown from the weekend said McLaren, Ferrari and Red Bull each brought significant updates, while Mercedes arrived with only a couple of new parts and held back a larger package for Canada. That meant Miami became the first proper side-by-side test of who had found performance during the spring break. ### Did Mercedes still look like the benchmark? Yes — but with an asterisk. Antonelli took his third straight Grand Prix pole and his third straight win in Miami, extending his championship lead and keeping Mercedes unbeaten on Sundays in 2026. That is still the headline result. But the race itself was tighter than the clean win column suggests, and the weekend around it showed rivals getting into the same conversation on raw pace. ### Where did McLaren make the biggest noise? McLaren looked like the clearest immediate threat. Lando Norris ended Mercedes’ unbeaten qualifying run by taking Sprint pole, then converted that into McLaren’s first Sprint win of the season. On Sunday, Norris finished second behind Antonelli, with Oscar Piastri third, which matters because it showed McLaren had pace across the whole weekend — not just one session, one tire window, or one lucky call. ### What about Ferrari? Ferrari brought a heavily upgraded car and flashed speed right away. Charles Leclerc topped the only practice session in Miami, which was the first signal that Ferrari’s package had changed the balance. But the catch is that early speed did not turn into a clean, high-scoring weekend. Inconsistency. ### And Red Bull? Red Bull’s weekend was messy, but not irrelevant. The team debuted new parts in Miami, including changes highlighted around the rear wing area, and Max Verstappen described the turnaround as “incredible” after the car looked more competitive than it had in Japan. He still spun in the Grand Prix and dropped out of the fight for the win, so the result undersold the pace. Basically, Red Bull may have found something even if the final classification hid it. ### Why does Mercedes’ smaller package matter so much? Because it changes how you read the weekend. If Mercedes had arrived fully updated and still got swarmed, that would look like a genuine loss of control. But Mercedes was deliberately lighter on new parts in Miami and is expected to bring a major package to Canada on May 22-24. So the current picture is not “Mercedes got caught.” It is closer to “the field narrowed before Mercedes played its next card.” ### So was Miami a turning point? Maybe — but not yet a completed one. Miami showed that Mercedes’ lead is real in results and shakier in margin. McLaren looks the most immediately dangerous, Ferrari has evidence its upgrade added speed even if execution lagged, and Red Bull seems less lost than it did before the break. The next clean read comes in Canada, when Mercedes brings its larger update and everyone gets another direct comparison. ### Bottom line Mercedes still owns the scoreboard. But Miami made the season feel alive again. The fastest team may still be silver — the catch is that it no longer looks comfortably alone.
