Which Formula One team is listed as the reigning Constructors' Champion in 2026?

McLaren-Mercedes is listed as the reigning Constructors’ Champion entering the 2026 Formula One season.

McLaren secured the 2025 Constructors’ Championship, its second consecutive team title. The championship is awarded to the constructor whose drivers collectively score the most points across the season, so it measures the strength of the entire team rather than one driver alone.

The 2025 crown was McLaren’s tenth Constructors’ Championship. It also completed a major turnaround for the team, which had returned to the front of the grid after several less competitive seasons. The title was clinched before the 2025 season ended, with McLaren’s points total becoming unassailable.

“McLaren-Mercedes” identifies both the constructor and its power-unit supplier. It should not be confused with the Mercedes works team, which is a separate constructor, or with Red Bull Racing, the dominant team earlier in the 2020s.
