George Russell entered the Hungarian Grand Prix weekend with a renewed sense of optimism, convinced that Mercedes have finally pinpointed and remedied the power‑unit anomalies that plagued his car at Spa. The British driver had suffered a costly first‑lap retirement at the Belgian round after a collision with Lewis Hamilton, a setback that widened the gap to his title‑leading teammate Kimi Antonelli to 50 points.
Russell believes the incident and his overall under‑performance in Belgium were largely the result of recurring issues with the engine's energy deployment system. During the practice sessions at Spa‑Francorchamps, Russell encountered a brief loss of straight‑line speed on the long Kemmel Straight, a symptom that hampered his lap times on the circuit’s lengthy lap.
In addition, the start of the race was compromised by a separate fault that affected all Mercedes‑powered cars, leaving them vulnerable to rivals behind them. These problems manifested as a lack of power off the line and an inability to fully exploit the car’s aerodynamic efficiency on the high‑speed sections. Despite the setbacks, Russell expressed confidence that the team’s engineers have finally identified the root cause and implemented a fix before the next race in Budapest.
"We’re pretty confident we have got on top of the issues we had in Spa and it should be easy to resolve," he told reporters. "We hope and we think we have got on top of it, so feeling more positive." He added that the data gathered at Spa gave the team the clues they needed to focus their investigations. "At the time we were not sure what it was, but the team have worked so hard to really dig deep.
Spa gave us the right pointers of where to look for the problem. It’s like pulling a needle out of a haystack – once you know where to search, the issue becomes clear. Fingers crossed the power‑unit problem is solved, but we’ll find out this weekend." When pressed about whether his driving style might have contributed to the loss of power, Russell dismissed that notion. "We think it was a software bug.
It wasn’t the driving style that was causing the power loss, so that’s at least one thing clarified," he said. He likened the diagnostic process to a meticulous investigation, emphasizing that the team’s persistence paid off in isolating the software glitch that had been throttling the engine’s performance.
Russell also reflected on the emotional turbulence of his season. Starting the year as a clear favourite for the championship, he has endured a roller‑coaster of form, punctuated by reliability hiccups from the Mercedes package. The 28‑year‑old described the campaign as the toughest psychological battle of his career, citing the mixture of personal shortcomings and external factors that have repeatedly derailed his momentum. "It’s probably fair to say it’s the toughest battle psychologically I’ve had because there have been so many ups and downs, combined with things in my control that haven’t been great and also things outside of my control that have hampered progress," he admitted.
Yet he stressed his resilience, echoing the adage that adversity builds character. "What doesn’t kill you makes you stronger, and I feel proud of my resilience.
Three days after Spa I feel positive and excited for the weekend and I’m looking at future prospects, not past disappointment." The upcoming race at the Hungaroring offers a different set of challenges. Unlike Spa or Silverstone, the Hungarian circuit is less dependent on outright power, favouring chassis balance and cornering stability.
Russell, who has previously stood on the podium there twice and secured his maiden pole position in 2022, sees the venue as an opportunity to rebuild the momentum he enjoyed after his Austrian Grand Prix victory earlier in the season. "I felt some good momentum coming out of Austria and Barcelona, especially after Monaco," Russell recalled. "Monaco was a very low point for me, but then I got pole in Barcelona, P2 in the race, pole in Austria and the win – I felt a real good momentum building, which was halted in Silverstone and Spa. I hope I can continue from where we were in Austria." He expressed enthusiasm for the Budapest weekend, noting that the track’s lower reliance on power plays to Mercedes’ strengths in chassis development.
"We know it’s one of the least power‑sensitive circuits of the season. Ferrari are close behind with a better chassis than power unit at the moment, so you can expect them to be competitive here," he said. He also acknowledged Antonelli’s strong form, warning that the battle for the 2026 world title remains very much alive.
"For sure I can still win it," Russell asserted. "We’re not even halfway through the season. It’s been so up and down – four races ago I was a lot more points behind in the championship than I am now, even with the Spa disappointment. I’m feeling a lot more positive, excited for the weekend ahead, and I hope I can just focus on driving quick." The schedule for the Hungarian Grand Prix weekend includes multiple support series, with practice sessions for F3 and F2, qualifying, and sprint races leading up to the main event on Sunday.
All sessions will be broadcast live on Sky Sports F1, and fans can stream the coverage via NOW without a long‑term contract. In summary, Russell heads into Budapest with a repaired power unit, a clearer mind, and a determination to capitalize on a circuit that rewards handling over raw horsepower. If Mercedes have indeed eliminated the software bug that hampered his Spa performance, the British driver could well turn his season’s narrative from a tale of setbacks to one of redemption, challenging both his teammate and Ferrari for the championship lead as the summer break approaches.
