Monza is proving to be the ultimate test for energy management in the 2026 Formula 1 cars. The regulation changes this season have made this circuit the most energy-hungry, and distinct patterns in energy deployment are emerging among the teams.
Ferrari arrives with its latest upgraded power unit, but doubts remain whether it can truly challenge Mercedes, which is still considered the benchmark. Data from the practice sessions reveals intriguing patterns that could be key for the race.
FP2 Comparison: Russell vs Leclerc
George Russell's fastest lap in FP2 showcased Mercedes' strength on the straights. Charles Leclerc lost significant time before the Ascari chicane but gained it back in the final sector towards Parabolica.

This suggests a different energy deployment strategy. If this holds, the opening laps on Sunday could be intense, as Ferrari is known for being opportunistic at the start with different engine modes.
The Strength of Ferrari's Upgraded Engine
A comparison between the two Haas drivers offers a unique chance to evaluate Ferrari's upgraded power unit. Ollie Bearman, using the new engine, showed superior straight-line speed compared to teammate Esteban Ocon, who is still on the old spec.
However, the significant time gap is also influenced by the parts inconsistency issues that have plagued Ocon all season, often leading to loss of downforce and affecting overall performance.
To truly measure the engine difference, those consistency issues must be resolved. Meanwhile, Haas's aero upgrade, fitted on both cars, is starting to show positive results, with Bearman describing it as the best Friday since March.
Where McLaren is Lacking
McLaren's expectations of a tough Monza weekend were confirmed on Friday. Lando Norris was nearly four-tenths behind Russell in single-lap pace, and slightly further off in long-run simulations.
McLaren's Technical Director for Engineering, Neil Houldey, admitted that from an energy perspective, they are still working to find the right balance. This is a homework they need to complete quickly to compete at the front.
