Bono Reveals the 'Stern Conversation' That Ignited Antonelli's Title Run

Kimi Antonelli is Formula 1's newest world champion, and his race engineer says a blunt mid-season reckoning during his rookie campaign was the turning point. Peter 'Bono' Bonnington revealed a "really stern conversation" at the end of the 2025 European season reshaped the Italian's approach — roughly a year before he sealed the 2026 title with third place at the Mexican Grand Prix.

Why it matters:

Mercedes bet on Antonelli as Lewis Hamilton's replacement while he was still a teenager, and the payoff arrived faster than most expected. Bonnington's account also underlines how much of a race engineer's job happens away from the data screens.

The details:

• Antonelli, 20, clinched the championship in Mexico City with nine grand prix wins already banked this season.
• He took the points lead at round three with back-to-back victories in China and Japan, despite George Russell being widely tipped as the title favourite.
• The groundwork was laid in 2025, when a rough stretch through the European rounds left the rookie struggling.
• Bonnington: "We had a really stern conversation... and then we got into the flyaways again and all of a sudden he was just like, 'Why didn't you give me a kick up the arse sooner?'"
• "You learn from your bad days and that's what he's really good at doing — just learning."

Between the lines:

Bonnington, who previously engineered Hamilton and Michael Schumacher, shrugged off the idea that drivers need sports psychologists. "Half of the job is looking after the car, the other half is keeping the driver happy," he said. Few engineers have a better frame of reference for handling elite talent.

What's next:

Antonelli now has to prove he can defend it, with Russell still chasing a first title of his own.
