Mercedes had hoped the 2026 regulations would return it to the front of the field.

It may have got even more than it had bargained for.

The German marque is undefeated in the chase for grands prix victories and has yet to be beaten to a Sunday pole position. Though upgrades in Miami condensed the field, Mercedes has kept its powder dry for upgrades coming to Canada next weekend and is confident it can ensure a straightforward run to the constructors championship.

What it didn’t count on, however, was having a drivers title fight on its hands.

Andrea Kimi Antonelli, in just his second season, leads the championship at a historically young age.

Having won the last three grands prix on the bounce, he heads his more experienced teammate, George Russell, by 20 points.

“What we love about this sport is that the clock never lies at the end of the race,” Mercedes boss Toto Wolff told Gazzetta dello Sport.

“The clock says Kimi has deservedly won the last three GPs.

“Russell hasn’t done as well, in some cases due to team problems, bad luck, and in Miami due to his own mistakes.

“That said, we know George’s value and we know he’ll return, starting from Canada, very competitive and ready to make life difficult for his opponents.”

It’s not just his opponents for whom Russell will be hoping to make life difficult.

To win the title, he’ll have to make life difficult for his Mercedes team too.

It’s been only four grands prix, but already we’ve seen enough to know that Antonelli can be a genuine championship contender. With momentum on his side, he’s had the measure of a driver most expected to be romping his way to a massive title lead by now.

It wasn’t supposed to be this way.

Antonelli, nine years and 128 starts Russell’s junior, was supposed to be the understudy to his British teammate, learning the ropes as the sister car led the way.

It was supposed to be a harmonious, frictionless, mutually beneficial relationship.

Instead, after a decade an intrateam tranquillity, Mercedes could have another internal championship fight on its hands.

FAITH IN ANTONELLI PAYS OFF

At the core of Mercedes’s unexpected reality is Antonelli’s sizzling start to the year.

While he ended 2025 in good form, there was little that indicated these sorts of performances were possible.

He finished on the podium only three times to Russell’s seven, taking no wins to his teammate’s two.

He went missing for most of the middle of the season, scoring just three points in the nine rounds constituting the European leg of the campaign.

His form was so poor during the year, in particular at his home races in Italy, that Wolff and race engineer Peter Bonington had to sit him down to, in Antonelli’s words, “kick him in the butt” in a last-ditch effort to prevent him from drowning on motorsport’s biggest stage.

His form began improving thereafter, but even so, winning three of the opening four grands prix never looked on the cards.

“Absolutely [I’m surprised],” Wolff said. “Last year I often repeated: taking an 18-year-old into the team would have made us experience moments of celebration and others in which we would have liked to tear our hair out for his mistakes, but it was a necessary path to get him to know the team.

“I expected a good start, but I have to admit: three wins in a row were not something we had expected.”

It’s not just that he’s won three on the bounce. It’s that each win has been better than the last.

In China he was fortunate that technical problems in qualifying prevented Russell from challenging him from pole, which in turn gave him a clearer run in the race — though he was strong in converting to victory.

In Japan he needed the safety car to beat Oscar Piastri to victory, though he was clearly the quicker Mercedes driver before that, even if a worse start dumped him into the pack.

In Miami, though, there were no asterisks. He easily had Russell’s measure all weekend, and he was superb in executing the strategy that got him into clear air ahead of Lando Norris, whose pressure he then absorbed for the rest of the race on his way to a hard-earned third win.

Win after win, he’s making good on the potential Wolff and Mercedes saw in him.

“It is easier to calm someone down that is wild, because you won’t be able to accelerate a donkey,” Wolff said.

“For me that was his best race so far. It reminds me of his karting days — there were no mistakes.

“It is astounding, these few races … how he has been able to capitalise [on the car] is special.”

RUSSELL’S UNENVIABLE POSITION

It puts Russell in a potentially awkward position, and for two reasons.

The first is obvious. The more experienced Englishman is being beaten by his younger teammate at a time Mercedes is comfortably ahead of the field. The fight should be as straight as it can get, and Russell has been found wanting.

It would be painful in any season, but it’s especially so when the Briton has been waiting so long for his championship challenge, having toiled at Williams during Mercedes’s title-winning pomp and then having been lumbered with uncompetitive Mercedes cars after finally getting the call-up in 2022.

Already he lamented that his still-young career had been a case of being in the right place at the wrong time. That trend could continue even in championship-contending machinery.

But there’s a second even more uncomfortable element to all of this.

There’s a risk he’s rapidly replaced by his designated successor.

Antonelli was always destined to replace Russell as Mercedes’s number one, but the intention had been for that moment to come several years from now, perhaps after the Briton had won some titles and established himself in the Formula 1 pantheon. Separated in age by almost a decade, there never seemed to be a realistic prospect of them fighting over the same piece of history.

But the future has arrived rapidly.

There’s some important context to this.

One piece of it is that Antonelli is Wolff’s gamble. He accelerated his rise through the junior ranks and then pushed for him to get his Formula 1 debut earlier than planned when Lewis Hamilton decided to quit the team.

Wolff has been riding the rollercoaster with Antonelli, and he’s now basking in the success of his gut instinct.

That’s not to say Wolff isn’t invested in Russell — the Englishman too is a product of the Mercedes driver academy and is tied directly to the Austrian powerbroker — but his journey to F1 was far more conventional, far more self-made.

Consider that now alongside the second piece of context.

Russell was, for a period of time last year, on the chopping block for a possible Max Verstappen arrival.

The Briton — for all the fanfare around his potential — had his contract negotiations indefinitely halted while Wolff discussed Verstappen’s future with the Dutchman’s representatives.

We know this because Russell told us in a bid to put pressure on his boss to make a call.

Verstappen, in the end, wasn’t free to break his Red Bull Racing contract — ironically he would’ve had to have been behind Russell on the title table to do so — and the deal was eventually done.

Russell now says his contract — which the team announced as lasting only a year but which is regarded as having options for further season on it — is tilted more in his favour, with certain results enough to lock him in for next season and beyond.

But surely that longwinded saga is sitting somewhere in the back of his head, waiting to activate in some particularly dark moment.

That Wolff, his team boss and de facto manager, was willing to trade him in for one of his rivals — and not the young gun who, for all his promise, was flailing through the middle of the season scoreless.

WOLFF’S BATTLE SCARS

Championship rivalries always come with tension, but when the drivers are also teammates, both must endure additional stress.

That stress is borne also by the team. The opposite sides of the garage want badly to beat each other, but management must attempt to keep the ship rowing in the same direction.

Mercedes of course has been here before. Between 2014 and 2016 it hosted one of Formula 1’s most toxic rivalries, between Lewis Hamilton and Nico Rosberg.

The childhood friends turned became bitter nemeses during Hamilton’s 2014–15 championship campaigns but blew up in early 2016, when Rosberg built a head of steam that would eventually set him up to clinch his sole world championship at the final race.

Their crash on the first lap of the Spanish Grand Prix was so internally damaging that threatened both with the sack.

The circumstances and characters involved in 2026 are vastly different to those of a decade ago, but Wolff still carries the scars of those combustive years.

“The oddity in Formula 1 is that the two teammates are also the biggest competitors,” Wolff said earlier this year, per the F1 website.

“There are certain values that we stand for in the team. The team is always bigger than the drivers.

“Having the opportunity to race to be one of the few selected racers for Mercedes also comes with a responsibility.

“The moment the driver feels like this is all about him, that’s not the mindset that we would ever allow, accept, in the team — and we’ve done that in the past.

“I would rather have only one car driving if that wasn’t clear.

“But I think it will never come to that point because our drivers, they’ve been so long in the Mercedes family that they are part of that mindset and this philosophical approach and the legacy that they represent.“

HOW DOES IT END?

Antonelli’s 20-point lead is a healthy buffer but far from unassailable. Three grand prix victories would be enough for Russell to overcome the disadvantage and return the campaign to its expected trajectory.

With so many races still to run, it’s far too early to start counting points.

We can’t even count out the possibility of other teams joining the fray, complicating the mathematics and perhaps even putting Mercedes on the back foot.

And for all of Antonelli’s obvious and prodigious ability, the fact he’s in only his second Formula 1 campaign will surely become a factor at some point this season.

Over the balance of a year at the coalface, you’d still back Russell to be the less error prone and less prone to long stretches of competitive anonymity.

Consider last year as a possibly indicative example.

Russell was arguably the most consistent driver of the year, and though Mercedes’s ceiling was far lower, it was extremely rare that the Englishman didn’t get the maximum from his car.

Antonelli had some exciting highs but also had that three-point Europe slump. Of course there were some additional factors in that fallow period — a Mercedes upgrade that complicated the car and that was eventually corrected, plus some unfortunate unreliability — but he also can’t expect this season to be perfectly smooth either. He may have to overcome similar challenges.

That’s on top of experiencing the fight at the front of the Formula 1 field for the first time. He’ll need to do a lot of learning on the run while contending against a driver with far more experience.

But Russell won’t be able to simply cruise on his experience alone.

Antonelli will feel the pressure, but it will weigh more heavily on Russell the longer the scores remain close — or the further he falls behind.

It’s the reason this has become a topic of interest in the first place.

Russell was expected to win the title because of his experience and because of his good form last year. He’s still expected to win the title for those reasons.

And he knows it. He expects it too.

He’s been talked about as England’s next world champion for years — before and after Lando Norris beat him to it.

He even suggested that, had he arrived at Mercedes a few years earlier — that is, during its title-winning pomp — he would’ve had two world titles to his name by now for having beaten post-2021 Hamilton in non-contending cars in 2022 and 2024.

If Antonelli wins the title, it’ll be a remarkable, historic achievement. If he doesn’t, it’ll be expected and understandable.

If Russell wins the title, it’ll be expected and understandable. If he’s beaten there by Antonelli, it’ll be a remarkable and perhaps defining fumble.

Wolff, meanwhile, has to hold the team together throughout, because one of his drivers will go home from Abu Dhabi disappointed. His job will be to ensure neither burns their bridges on the way out.

There’s always a lot on the line in the fight for the Formula 1 world championship.

But the clock never lies — and the clock is ticking.
