George Russell has singled out Max Verstappen and Charles Leclerc as Mercedes’ chief threats as the 2026 Formula 1 season nears and teams prepare for the Australian Grand Prix.
After a strong pre-season showing, Mercedes are among the bookmakers’ favourites and drew praise from Sky Sports F1 pundits, helped by their history of adapting well after major power unit regulation changes. While Ferrari posted the fastest single-lap times in Bahrain testing, Mercedes appeared particularly competitive over long runs and did not necessarily reveal their full one-lap pace.
When asked who he views as his main challengers for the Drivers’ Championship, Russell pointed to Verstappen and Leclerc. Team-mate Kimi Antonelli echoed those concerns, highlighting Red Bull’s strength and Ferrari’s promising balance on both long runs and qualifying trim. Antonelli also cautioned not to discount Lewis Hamilton and suggested McLaren could still be a factor despite seeming a little behind Ferrari and Red Bull in testing.
On media day Russell tempered his initial comments, praising Red Bull’s engine performance and acknowledging Ferrari’s speed. He noted that Red Bull have surprised many with their power unit, which naturally keeps Verstappen in contention, and reiterated that Leclerc and Hamilton should not be underestimated. He also warned that McLaren’s relative position could change quickly, pointing to recent seasons where teams have moved from the back toward the front.
Having spent four seasons at Mercedes without mounting a full championship assault — largely because the team did not always provide a consistently winning car — the 28-year-old described 2026 as a significant opportunity. Russell said he feels ready to fight, is focused on extracting the maximum from the car, and stressed that sustained development during the season will be crucial: starting well matters, but continuous improvement race by race is what wins titles.
Russell also voiced concern about fluctuations in Red Bull’s testing pace. He said during the first Bahrain session Red Bull looked to hold a sizable advantage in energy deployment, but that gap appeared to shrink dramatically in the subsequent test. Mercedes data suggested Red Bull ran roughly seven tenths slower week to week, while Mercedes and Ferrari picked up performance with upgrades. Under new power unit rules, energy deployment — split roughly 50/50 between the internal combustion engine and electrical output — is expected to be a decisive factor.
Red Bull, which developed its powertrains in collaboration with Ford, had been tipped to face early challenges but largely ran reliably and competitively in testing. Verstappen declined to draw direct comparisons, saying he was pleased with the pre-season work and proud of how the engine and car project had come together. He acknowledged the complexity of the rule changes, said there is room for more performance, and admitted uncertainty about how the teams truly stack up.
As the field heads to Melbourne, teams and drivers must weigh testing data against the unknowns of race weekends. Mercedes, Ferrari and Red Bull are all seen as realistic title contenders entering the opener.
