Kimi Antonelli stood on the Hungarian Grand Prix podium with another trophy and a larger championship lead. George Russell recovered from a disastrous launch to score points in 7th. Mercedes also left Budapest 72 points clear of Ferrari in the Teams’ Championship.
Those results suggested a successful afternoon. Toto Wolff saw something very different.
Mercedes spent much of the weekend chasing a car balance it never fully found. Antonelli surrendered valuable practice mileage, Russell’s qualifying ended with a water leak, and a fresh power unit failed to respond correctly during the start procedure. At the tight 14-corner Hungaroring, every setback pushed the drivers deeper into traffic and narrowed the team’s strategic options.
Antonelli rescued 3rd with a measured 2-stop race and a tense late defence against Lewis Hamilton. Russell carved through the midfield after falling to the rear. Their work protected Mercedes from a far worse result. It did not hide the mistakes that forced both cars into recovery mode.
Mercedes Paid the Price for a Compromised Friday
Antonelli did not simply volunteer his car to Fred Vesti for opening practice. Mercedes used the session to satisfy part of Formula 1’s rookie running requirement, which requires every regular driver to give up 2 practice sessions during the season. Vesti completed 24 laps and placed 7th in his second rookie outing of 2026.
The allocation was planned, but the timing still carried a cost. Hungary’s resurfaced track was bumpy, rear grip was poor, and tyre degradation ran higher than Mercedes expected. Antonelli returned for FP2 without the reference mileage collected by Russell and immediately struggled with the car’s balance.
A red flag interrupted his soft tyre attempt. Traffic spoiled another lap, while rear locking further complicated his search for confidence. Russell finished 5th in both Friday sessions, but Mercedes lacked convincing single-lap speed and continued making substantial mechanical changes.
By Saturday, the team had improved the W17 without solving it. Antonelli qualified 4th before a 3-place penalty for failing to slow sufficiently under yellow flags sent him back to 7th. Russell qualified 7th, then inherited 6th on the grid.
His final qualifying lap had already exposed a more serious problem.
Russell’s Water Leak Triggered a Full Power Unit Change
Russell reported water spraying toward the tyres during his last Q3 run. Mercedes detected a loss of water pressure and ordered him to stop after the lap as a precaution.
Further checks forced the team to replace the complete power unit before the race. The change moved Russell onto his 4th unit of the season, still within his permitted allocation. Mercedes fitted components of the same specification, so the work incurred no grid penalty or parc fermé sanction.
The fresh engine then created another problem at the worst possible moment.
About 4 seconds before the lights went out, Russell felt the revs surge without matching his throttle input. Telemetry showed the engine climbing to roughly 12,800 rpm, while Antonelli’s remained stable near 12,300 rpm. Russell reduced his pedal input to below 10%, but the revs continued to fluctuate. When he released the clutch, the engine bogged down and triggered anti-stall.
Russell dropped from 6th to the rear before Turn 1. Mercedes initially questioned his launch inputs over the radio, but Wolff later cleared the driver of any fault. “The prevailing feeling is that we should have done better,” he said, directing the blame toward the team rather than the man inside the car.
Russell Tore Through the Midfield
Russell did not wait for strategy to rescue him. He swept around Valtteri Bottas at Turn 5 on the opening lap and immediately began cutting through the traffic ahead.
The Mercedes passed cars almost every lap during the opening phase. Russell attacked into Turn 1, pressured rivals into mistakes through the middle sector and used stronger exits to complete moves before the braking zones. Alpine, Aston Martin, Haas, Williams and Sauber machinery all disappeared behind him as he dragged the car back toward the points.
By Lap 17, Russell had gained 10 positions.
He then cleared both Racing Bulls and settled into the fight around 7th after the pit sequence. Russell finished only 2.015 seconds behind Isack Hadjar’s Red Bull, a margin that sharpened the frustration inside Mercedes.
The pace was clearly present. A podium challenge had vanished before the race had properly begun. Wolff called the weekend “not great,” a blunt assessment of a result that depended far too heavily on Russell repairing the damage from Mercedes’ own technical failure.
Antonelli Faced Hamilton in Ferrari Red
Antonelli anchored Mercedes’ Sunday from 7th on the grid. He gained 1 place at the start and extended his opening medium tyre stint while the leading cars stopped around him.
A possible 1-stop race remained alive until Mercedes brought him in for hard tyres on Lap 22. Antonelli ran long again, but degradation across the rear axle meant the tyres could not reach the finish at a competitive pace. When he questioned his second stop on Lap 54, his engineer delivered a direct answer. The car did not have enough tyre life.
That decision gave Antonelli fresh hard tyres and the pace to move into podium contention. Oscar Piastri’s retirement then triggered a Virtual Safety Car shortly after the stop. Hamilton used the neutralised period to fit soft tyres for Ferrari and initially emerged ahead, but timing at the control line restored 3rd place to Antonelli.
The closing laps carried extra weight. Hamilton, the 7 time world champion who spent 12 seasons with Mercedes, filled the mirrors of the team’s new championship leader while driving for its greatest rival.
Antonelli had the harder and slower compound. Traffic ahead compressed the gap, while Hamilton’s softer tyres gave the Ferrari more grip under braking and better traction out of the slow corners.
Still, Antonelli refused to crack. He protected the inside line, controlled his exits and avoided the wheelspin that would have given Hamilton a clear attack. The Ferrari remained close, but never found a way through.
Antonelli crossed the line in 3rd. Hamilton’s 5-second pit lane speeding penalty later dropped him behind Charles Leclerc in the final classification.
Strong Standings Cannot Hide Weak Execution
Antonelli now leads Hamilton by 50 points and Russell by 59. Mercedes holds a 72-point advantage over Ferrari as Formula 1 enters its summer break.
Budapest still exposed a weakness that the standings cannot measure. Mercedes lost preparation time, missed its ideal setup, changed Russell’s engine and then suffered a software-related launch failure with the replacement unit. Neither driver caused the major setbacks.
Antonelli and Russell supplied the quality that the operation around them lacked. One absorbed pressure from a former Mercedes champion. The other recovered 14 positions after a technical failure destroyed his start.
Heroic driving salvaged the weekend. Mercedes cannot allow it to become the repair plan.

FAQs
Why was Toto Wolff unhappy after the Hungarian Grand Prix?
Mercedes scored a podium, but setup problems, a water leak and Russell’s start failure forced both drivers to recover from avoidable setbacks.
Why did Fred Vesti drive Antonelli’s Mercedes in FP1?
Mercedes used Vesti to complete part of Formula 1’s mandatory rookie practice requirement. Antonelli therefore missed the opening session.
What happened to George Russell at the start in Hungary?
His engine revs fluctuated during the launch procedure. The car bogged down, triggered anti-stall, and dropped Russell to the rear.
How did Kimi Antonelli finish 3rd in Hungary?
Mercedes changed him to a 2-stop strategy. Fresh hard tyres lifted him into contention before he defended 3rd from Hamilton.
How large was Antonelli’s championship lead after Hungary?
Antonelli led Hamilton by 50 points and Russell by 59 after finishing 3rd at the Hungaroring.
