US Grand Prix stewards: why Russell's penalty was halved and the grid penalties that shaped Austin

The stewards' room was busy throughout the United States Grand Prix weekend at the Circuit of the Americas, and one decision in particular may have shaped the 2026 championship timeline. George Russell's first-lap penalty helped drop him to eighth, the exact result he needed to stop Kimi Antonelli being crowned champion, yet the Mercedes driver himself pointed to a bigger problem than the sanction.

Russell's lap-one penalty, explained

On the opening lap Russell was battling Isack Hadjar's Red Bull into Turn 12 when he ran wide. He rejoined ahead of Oscar Piastri before Turn 13 and kept the position, and the stewards ruled that he had left the track and gained a lasting advantage.

The stewards noted that the usual penalty for this kind of offence is 10 seconds, but they halved it to five. They cited two mitigating factors: Russell had been putting pressure on Hadjar, which created the attacking opportunity for Piastri, and the incident happened amid the chaos of the first lap.

Russell served the penalty during his lap-23 stop, rejoined in 10th place on hard tyres, and could not find a way back past Piastri. He finished eighth for four points, which kept him 123 points behind Antonelli with 125 still available.

Russell blames pace, not the penalty

Afterwards Russell accepted that the penalty had cost him two or three places, but he was blunt about his overall performance. "The pace was rubbish today," he said, and he admitted the team did not yet understand why he had been so far off his team-mate, who won the race by 13 seconds.

Stroll sent to the pit lane

The biggest pre-race sanction fell on Aston Martin. After a report from FIA technical delegate Jo Bauer, the stewards found the team had broken parc fermé rules on Lance Stroll's car. Five power-unit components were replaced without approval, the suspension set-up was altered, and work continued well after qualifying had ended. Rather than applying five-place drops for each component, the stewards ordered a pit-lane start. Stroll had been knocked out in Q1 and was due to line up 16th; he eventually finished 15th, one place ahead of team-mate Fernando Alonso.

A reshuffled grid

Several other drivers took grid penalties for using extra engine parts. Audi's Gabriel Bortoleto was sent to the back after the team exceeded its power-unit allocation, and recovered to 13th. Alpine's Franco Colapinto took a ten-place drop and later retired, while Racing Bulls rookie Arvid Lindblad lost five places for an additional internal combustion engine but still finished 12th.

Hadjar warned for practice swerve

Hadjar also had a brush with officialdom before the race. Near the end of Saturday's final practice, Williams driver Alex Albon moved to the outside at Turn 1 to avoid holding up the Red Bull. Hadjar locked up and abandoned his lap, then moved towards Albon in what the stewards described as retaliatory action. He was given a formal warning rather than a penalty, and went on to finish sixth in the race.

Key takeaways

• Russell's penalty was cut from the standard 10 seconds to five because of first-lap mitigating factors.
• Russell finished eighth and said his pace, not the penalty, was the main problem.
• Stroll started from the pit lane after Aston Martin breached parc fermé rules.
• Bortoleto, Colapinto and Lindblad took grid penalties for extra power-unit parts.
• Hadjar received a formal warning for swerving towards Albon in practice.
