# Mercedes and Ferrari battle for 2026 F1 championship > Live situation record from CLSTR: https://clstr.news/situations/mercedes-f1-upgrade-strategy > Updated: 2026-09-09T08:49:58.000Z. Sources: 59. Developments: 12. The 2026 Formula 1 championship battle between Mercedes and Ferrari has shifted focus toward engine performance following the Italian Grand Prix at Monza. Ferrari deployed a significant technical package at Monza, utilizing the FIA’s Additional Development and Upgrade Opportunities (ADUO) system to introduce an evolved power unit for Lewis Hamilton and Charles Leclerc. These upgrades targeted engine performance and turbocharger efficiency, paired with a new low-downforce rear wing. The weekend also served as a tribute to Michael Schumacher, with drivers wearing special liveries featuring seven stars. Despite these efforts, Ferrari’s performance at Monza was mixed. Charles Leclerc retired following a collision, and Hamilton finished sixth. Team Principal Frédéric Vasseur admitted that the Scuderia still lacks ‘pure power’ compared to Mercedes-powered rivals. Vasseur noted that while the team can manipulate energy distribution to compensate on straights, such adjustments can trigger a ‘negative spiral in performance.’ Ferrari confirmed it cannot implement further engine hardware upgrades this season, shifting its development focus toward 2027. Mercedes maintains confidence in its championship lead despite facing mounting pressure from Ferrari and McLaren. While not possessing the fastest car in recent outings, Mercedes is preparing a major upgrade package for the Malaysian Grand Prix and an engine update following the Azerbaijan Grand Prix to defend both the drivers' and constructors' titles. ## Claims - Ferrari team principal Fred Vasseur stated the team must improve execution to avoid losing points.
