A senior figure within McLaren’s technical leadership has expressed strong confidence that the team can close the gap to Mercedes in the 2026 Formula 1 championship fight, insisting the Silver Arrows are far from untouchable despite their commanding start to the season.
After three rounds under Formula 1’s sweeping new regulations, Mercedes-AMG Petronas Formula One Team have emerged as the early benchmark. The Brackley-based outfit has quickly adapted to the revised technical framework, seizing the initiative in both the drivers’ and constructors’ standings. Under the stewardship of Toto Wolff, Mercedes once again appear to have mastered a regulation reset — a hallmark of their previous dominant eras.
However, McLaren believe the competitive picture could shift significantly in the coming weeks.
Earlier this year, the FIA ruled that a compression ratio interpretation used within Mercedes’ power unit would no longer be permitted once a sporting regulation amendment comes into effect on June 1. As a result, Mercedes must introduce a revised engine specification ahead of the prestigious Monaco Grand Prix on June 7.
Industry projections suggest the enforced modification could cost as much as three-tenths of a second per lap — a potentially decisive margin in what has so far been a tightly contested field. Such a reduction would inevitably impact Mercedes’ customer teams as well, including McLaren F1 Team, who also run Mercedes power units.
Yet McLaren’s technical director, Mark Temple, has underlined that the Woking-based squad’s development focus lies elsewhere. Speaking on the F1 Nation podcast, Temple emphasized that the early phase of a new regulation cycle often leaves significant untapped performance within the chassis itself.
According to Temple, many teams are only beginning to unlock the aerodynamic and mechanical potential of their 2026 cars. He suggested that while power unit performance can shape early-season narratives, long-term competitiveness will be defined by how effectively teams evolve their chassis concepts.
McLaren are expected to introduce a substantial upgrade package at the upcoming Miami Grand Prix, targeting gains in aerodynamic efficiency and mechanical balance. The team believes these improvements could narrow — or even eliminate — Mercedes’ current edge before the European leg of the season begins in earnest.
While Mercedes’ early dominance has set the standard, McLaren remain confident that the championship battle is only just unfolding. With regulatory adjustments looming and a major upgrade cycle underway, the papaya outfit are positioning themselves as serious contenders in what could become one of the most dynamic development races of the hybrid era’s next chapter.
