Formula 1 drivers will arrive at the Monaco Grand Prix facing a set of energy deployment restrictions unlike anything seen at other circuits this season. Where most venues have struggled to provide enough energy for the 2026 cars, Monte Carlo sits at the opposite extreme — and that creates its own set of complications.
The tight and twisty street layout, with its heavy braking zones and low-speed corners, is a near-perfect environment for harvesting energy. With short straights offering little room to drain the battery, there is plenty of electrical power available at all times. But that abundance, rather than being a straightforward advantage, has triggered a safety concern: cars with too much deployable power risk arriving at corner entries at dangerously high speeds.
As part of its response, the FIA is mandating a specific engine mode setting for Monaco — designated 'Rev 1' — which limits maximum power deployment on the straights. As previously reported, Monaco will also be the first race of the 2026 season without straight mode activation zones, a decision made in part for the same safety reasons.
Under the standard 'Base' mode, maximum deployment begins tapering off only from 290 km/h. The 'Rev 1' setting is considerably more restrictive: the MGU-K's 350 kW cap starts to taper as early as 200 km/h, and by 300 km/h, no battery deployment is permitted at all.
When overtake mode is activated, the reduction rate is less aggressive — drivers using it can access 150 kW at 300 km/h — but the deployment tapers sharply to zero by 310 km/h.
Monaco also holds the distinction of having the shortest power-limited distance on the 2026 calendar, at just 1,388 metres. For context, Spa-Francorchamps requires mandatory power-reduction compliance over 4,594 metres, while Monza sits at 4,218 metres.
Despite the additional power restriction imposed by 'Rev 1', drivers are broadly optimistic about Monaco. After a season marked by frustrating energy shortfalls and awkward lift-and-coast tactics, the Principality is expected to offer something closer to a natural, free-flowing driving experience.
Haas driver Ollie Bearman was candid about his expectations: "Maybe they'll be a bit more fun to drive! That could be nice. I don't think there's really much opportunity to innovate in terms of energy in Monaco, just because of the limits with the speed, it's very early in Monaco for obvious safety reasons. But I think it's just going to be a bit more like last year, where we can just drive how we want, use the gears that we want, and not have to do any silly lift-and-coast and these things. I'm actually quite looking forward to it. It should be good."
Ferrari's Charles Leclerc shared the sentiment, highlighting the particular advantages the 2026 car characteristics could bring to the streets of Monte Carlo: "I think Monaco is actually going to be one of those races where these cars might be very good. First, we have now lighter cars, which for a track like Monaco, I think this has its benefits. The electric side is going to be a lot less big in Monaco, just because we'll be recharging quite a bit with all the corners that there are. So I think, yeah, I'm quite excited for Monaco. I think it should be a good track for these cars."
