Hamilton Questions Mercedes Engine Advantage at Australian GP, Fears Season Could Be ‘Done’
Lewis Hamilton has expressed concern over the sudden surge in performance from former team Mercedes at the 2026 Australian Grand Prix, questioning whether it stems from an exploitation of engine regulations. The Ferrari driver’s comments came after George Russell secured pole position, dominating qualifying with a significant margin over the competition.
Mercedes’ Dominance Raises Eyebrows
George Russell topped all three segments of qualifying at Albert Park, finishing 0.293 seconds ahead of teammate Kimi Antonelli. Red Bull’s Isack Hadjar was a further 0.785 seconds behind, while Hamilton qualified in seventh, nearly a full second off Russell’s pace. This performance sparked questions about the extent of Mercedes’ improvement, particularly given their relatively subdued pace during pre-season testing.
Compression Ratio Concerns
Hamilton specifically referenced the internal combustion engine’s compression ratio, which was reduced to 16:1 for the 2026 season. It has been alleged that Mercedes discovered a loophole allowing their engine’s compression ratio to expand in hotter conditions, potentially providing a performance advantage. “I don’t understand it exactly,” Hamilton stated. “They didn’t show that they could turn it up in testing and now they’ve got this extra power from somewhere and we need to understand what that is. I hope it’s not this compression ratio thing, hopefully it’s just pure power and we’ve got to do a better job.” Source: Motorsport.com
FIA Response and Regulation Adjustments
The FIA has acknowledged the concerns surrounding the compression ratio and announced a compromise in the regulations. Following “significant effort” from all parties, ratio tests will now be undertaken in both hot and cold temperatures starting in June. Source: Motorsport.com
Hamilton Warns Season Could Be Over
Hamilton expressed his fear that if Mercedes’ advantage proves to be substantial and sustained, the 2026 Formula 1 season could effectively be decided early. “If Mercedes has a few months head start, then the season is over,” he warned. “In seven races, in a few months, you lose a lot of points if you are one second behind in the standings.” Source: Sports Illustrated
Ferrari Struggles and Energy Management Issues
Ferrari also experienced difficulties during the Australian Grand Prix weekend, with Charles Leclerc qualifying in fourth and Hamilton in seventh. The team encountered problems with energy recovery and power delivery on the straights. Hamilton noted that the car had “much more potential” but struggled with battery energy management.

Looking Ahead
The coming races will be crucial in determining whether Mercedes’ performance is a genuine breakthrough or a result of exploiting a regulatory loophole. The FIA’s adjusted testing procedures, set to be implemented in June, will play a key role in ensuring a level playing field for all teams. Lewis Hamilton has also warned that the 2026 F1 season could be “done” if Mercedes’ advantage persists. Source: MotorsportWeek
