Monaco’s tight layout presents an unusual power unit dilemma for F1 teams: too much energy. The FIA allows maximum 9 MJ of energy harvesting, and with ample braking zones and short straights, batteries quickly fill. Crucially, the MGU-K’s deployment threshold drops to 200 km/h here, further accelerating energy recovery. This abundance of charge paradoxically becomes a problem.

A full battery prevents the MGU-K from assisting the turbo’s spool-up. Without the MGU-H, this leads to increased turbo lag, blunting acceleration out of Monaco’s many slow corners. Drivers like Liam Lawson confirm the challenge, while Oscar Piastri suggests rivals, including Ferrari with its smaller turbo, might gain an edge. Piastri expects drivers to utilize lower gears more frequently to maintain revs and keep the turbo responsive. Mastering this delicate energy balance, particularly on corner exit, will be critical for pace this weekend.
