Kimi Antonelli strengthened his grip on the 2026 Formula 1 World Championship with another victory at the Spanish Grand Prix in Madrid, but Mercedes team principal Toto Wolff is refusing to consider the title battle over. Despite the Italian now leading George Russell by 81 points and Lewis Hamilton by 101, Wolff believes reliability remains the biggest threat to his championship campaign.
Andrea Kimi Antonelli took advantage of the decisive Virtual Safety Car at the Madring to secure another win for Mercedes and further extend an already significant advantage in the Formula 1 drivers’ standings. On paper, his position is increasingly commanding, but Mercedes has already experienced enough reliability problems in 2026 for Toto Wolff to remain cautious.
Kimi Antonelli extends F1 championship lead in Madrid
Andrea Kimi Antonelli won again in Madrid after the timing of the Virtual Safety Car worked perfectly in his favour. Race Control activated the neutralisation immediately after then-leader Lando Norris had passed the pit-lane entrance, forcing the McLaren driver to complete another lap before stopping.
Andrea Kimi Antonelli and Max Verstappen, running second and third at the time, were therefore able to take advantage of the situation and move ahead of the reigning world champion through the pit-stop sequence.
The result gave Andrea Kimi Antonelli another major championship boost. The Mercedes driver now holds an 81-point advantage over team-mate George Russell and sits 101 points clear of Ferrari’s Lewis Hamilton.
That margin makes the young Italian the clear reference point in the title fight, particularly after a season in which he has repeatedly maximised his opportunities. GP-News has previously examined whether the growing gap between George Russell and Kimi Antonelli could have wider implications for Mercedes.
Toto Wolff warns reliability could still hurt Kimi Antonelli
Despite the increasingly favourable championship picture, Toto Wolff attempted to calm expectations when speaking to Sky Sport F1 after the race.
“It’s a mechanical sport,” Toto Wolff said. “We’ve already seen during this season that our car and also the engine have been a little fragile. Of course, today he [Antonelli] took a step forward [towards the title], and so did the team, and we’re happy about that, very happy. But you only celebrate when it’s mathematically certain.”
Mercedes has enjoyed a highly competitive season, but reliability has not always matched the performance of the W17. That explains why Toto Wolff is unwilling to treat Andrea Kimi Antonelli’s large points advantage as protection against an unexpected swing in the championship.
The team’s situation remains particularly important because any technical retirement could immediately erase a significant portion of the cushion that Andrea Kimi Antonelli has worked to build.
Wolff: ‘The opponent is reliability’
Asked directly whether reliability is now Andrea Kimi Antonelli’s main opponent in the championship, Toto Wolff agreed.
“Yes, absolutely. If you have one or two weekends without scoring points and the others score maximum points, then suddenly you’re no longer talking about 80 points but 50 or 30,” Toto Wolff explained.
“That’s why I keep saying that we need to keep our feet on the ground and stay focused on the work.”
It is a deliberately cautious position from the Mercedes team principal. Andrea Kimi Antonelli may now have a substantial championship advantage, but Formula 1’s long season leaves little room for complacency when mechanical failures can turn a seemingly comfortable lead into a much tighter fight within only a few races.
For Mercedes, the priority is therefore straightforward: maintain the performance that has allowed Andrea Kimi Antonelli to establish himself at the top while improving the reliability needed to protect that advantage.
