F1 2026: Mercedes' engine edge amid big rule changes

Formula 1 is undergoing its most significant rule changes in a generation for the 2026 season, with all car components being new. Despite a mixed 2025 season where McLaren dominated, Mercedes is being talked about as an early favorite. Bookmakers have positioned Mercedes as a joint-favorite for the 2026 constructors' championship, alongside McLaren.

Mercedes' history of excelling during major rule overhauls, particularly with engine development, fuels this expectation. Their High Performance Powertrains division has a strong track record. Even with new hybrid regulations for 2026, there are indications Mercedes may have found an advantage, possibly through a loophole in engine compression ratio rules.

This technical advantage, combined with the ability to perfectly integrate new engine designs into their chassis, could significantly benefit Mercedes. Furthermore, the team boasts strong drivers in George Russell and Kimi Antonelli, who are expected to be competitive. Pre-season testing will be crucial to determine if Mercedes can translate this potential into on-track success.
