# Mercedes F1 technical updates and Russell's championship gap > Live situation record from CLSTR: https://clstr.news/situations/mercedes-f1-technical-challenges-2026 > Updated: 2026-09-03T07:30:00.000Z. Sources: 253. Developments: 9. Following the summer break, Mercedes identified that George Russell’s performance struggles were caused by a calibration fault in the power unit’s deployment mapping. While these software issues were resolved in Hungary, a significant competitive gap remains in the 2026 championship, with Kimi Antonelli holding a lead over Russell. To manage championship pressures, both drivers have emphasized mental performance. Antonelli shared advice from Roger Federer to focus on one race at a time, while Russell has utilized a sports psychologist since 2020 to manage race weekend pressure. At the Dutch Grand Prix in Zandvoort, Mercedes secured a double podium. Lando Norris of McLaren won the race, but Antonelli finished second and Russell finished third. The race was marked by strategic team orders during a late Virtual Safety Car period; Antonelli pitted for fresh soft tires while Russell remained on track with older hard tires. To protect the team's overall standing and prevent Ferrari drivers from overtaking both Mercedes cars, the team instructed Russell to yield on lap 66. Russell stated the swap was ‘the right decision’ as Antonelli’s tire advantage would have likely seen him pass regardless, noting the move was consistent with team rules. Team principal Toto Wolff defended the move, stating it was necessary to maximize the team's overall points and avoid ‘unnecessary internal fighting’ while under pressure. Antonelli praised Russell as a “great team player” for his cooperation. Despite the order, Russell successfully defended his third-place position against Lewis Hamilton and Charles Leclerc in the closing laps. Following the result, Antonelli maintains a 59-point lead in the championship, while Russell and Lewis Hamilton continue a close contest for second place. At the 2026 Italian Grand Prix in Monza, George Russell showed strong form by topping both the second and third free practice sessions. ## Claims - Andrea Kimi Antonelli finished third at the Hungarian Grand Prix, extending his championship lead.
