As the Formula 1 community gears up for the 2026 power unit regulations, Mercedes’ Toto Wolff expects some teams to lag behind in their development. The new engine will feature 100% sustainable fuels, the removal of the MGU-H system, and a greater reliance on electrification, resulting in a 50/50 power split between internal combustion and electrical components. Wolff believes this shift will lead to varying levels of progress among teams, with some faring better than others.
