F1 2026: Mercedes dominant, Williams stuck in the garage and the big turbo era

F1 2026: Mercedes sweep the field, Williams can't turn a wheel and the big turbo era begins

The 2026 Formula 1 season got underway with an uncomfortable certainty: the Mercedes engine is once again making the difference. In pre-season testing, the W17 grabbed the headlines and fuelled suspicions that there is more to the German marque's advantage than technical superiority. Meanwhile, Williams, who also run the Mercedes power unit, couldn't even complete the Barcelona test due to safety problems with their chassis. The contrast is brutal: the same engine, opposite results.

Mercedes and the ghost of compression

The W17's first day on track produced one repeated phrase: "Mercedes are scary". It's not an isolated impression. Analysis from various quarters suggests the German engine may be running with compression parameters above the permitted limits, an accusation that keeps circulating and that the team has not publicly denied in the material available. The comparison with a Paco cup is inevitable: if you get caught with a skimmed head, you're disqualified. So far, nobody has shown the head.

The estimated advantage is around eight tenths per lap over the third-fastest team, a margin that at circuits like Barcelona translates into lapping entire teams. Some argue those 15 extra real horsepower are the key, while others prefer to look the other way because the regulations allow interpretations. The fact is the FIA hasn't made a move, and Mercedes' customer teams —Williams among them— don't seem able to exploit the same advantage.

Williams: same engine, no car

The Williams paradox deserves a chapter of its own. With Mercedes power, the British team should be a natural candidate to score points. Instead, they failed the safety tests and couldn't run in Barcelona. It's not a performance problem: they simply don't have a car. Starting from scratch six weeks before the championship begins is a scenario bordering on the farcical, and some analyses already place them last on the grid before they've turned a single wheel.

The comparison with McLaren in 2022 keeps coming up: they also started with the worst car of the era and ended up with the best. But that McLaren had a chassis. Williams' is, for now, a promise on paper. And meanwhile, the Mercedes engine keeps racking up kilometres in the garage across the pit lane.

Aston Martin and Honda: size zero takes its toll again

Aston Martin's case is another of the season's focal points. Alonso and Stroll's team hired a Red Bull engineer and, according to reports, brought along the blueprints of the championship-winning car. The result, far from bringing them closer to the front, has been one "rolling cowpat" after another. The problem is packaging: the Honda engine is so tightly enclosed it can't breathe. Two options: ruin the aerodynamics or change the engine. Neither is cheap.

The story recalls McLaren's "size-zero" era, when they wanted a more compact engine and ended up changing everything two years later. Honda, full of bravado, talk about winning the tests while their customers bleed out. The irony is that Aston Martin left the Mercedes engines to sign with Honda, and the visionary who made that decision may now be resting easy.

The regulations that kill the spectacle

Beyond the engines, the big underlying issue is the regulations. Energy management has replaced the pursuit of top estimulante ilegal. Drivers no longer take corners at the limit: they optimise batteries. DRS has become an energy-redistribution puzzle, and moving an overtaking zone means reconfiguring the entire engine. The result is a sport that looks more like data management than racing.

Safety has also taken its share. Under the current regulations, Senna would be alive, but it's also true that a race can be stopped over a bit of gravel. We've gone from losing two drivers in a single weekend to halting a race over a minor touch. The question is whether the pendulum hasn't swung too far. IndyCar, with its round in Barcelona, is starting to look sideways.

Antonelli and a championship decided in March

On the sporting side, the name on everyone's lips is Kimi Antonelli. The young Mercedes driver has racked up wins and poles while Russell suffers breakdown after breakdown and retirement after retirement. The gap exceeds a hundred points and some are already calculating he could be champion at the next race. Russell changes his engine and starts at the back of the grid; Antonelli, in the same car, starts first. The "chosen one" narrative writes itself.

The comparison with Piastri last year is inevitable: he also arrived young, also had an advantage, also found the season dragging. But Antonelli doesn't seem to feel the pressure. Meanwhile, Ferrari remain Ferrari, Verstappen takes poles that don't turn into wins, and Alonso limps along with the Aslow Martin to qualify sixteenth. At this point, the championship looks like a formality.

---

The 2026 season was supposed to be the closest in history. The data says otherwise: an engine that makes the difference, a team without a car, a rulebook that rewards management and a champion shaping up before the first corner. The question remains whether anyone can stop him. Or whether, quite simply, the spectacle no longer matters.
