FIA Imposes Mandatory Engine Mode in Monaco Grand Prix to Prevent Dangerous Top Speeds
· Yahoo Sports
Formula 1 drivers will face a massive restriction on the streets of Monte Carlo this weekend. The FIA has officially mandated a new, restricted engine mode specifically for the Monaco Grand Prix to intentionally cap top speeds and prevent severe safety risks.

The breaking news, highlighted by motorsport commentator @Nachez98 on X, confirms that the governing body is aggressively stepping in to manage the sheer amount of electrical energy the 2026 cars can harvest around the tight circuit.
FIA’s ‘Rev 1’ Safety Cap
According to an exclusive report from The Race, the tight and twisty layout of Monaco presents a unique problem for the new 2026 engine regulations. At other circuits, teams have struggled with severe battery drainage on long straights, leaving drivers completely underpowered. However, Monaco is entirely different. With its short straights and heavy braking zones, the engines can harvest a massive amount of electrical energy with zero risk of running out of deployment power.
This creates a terrifying scenario. If drivers were allowed to deploy their maximum 350kW electrical boost fully, they would arrive at Monaco’s tight corner entries at significantly higher, entirely unsafe speeds.
To neutralize this threat, the FIA is enforcing the “Rev 1” engine map. Under standard operating procedures, known as the “Base” mode, maximum electrical deployment only begins tapering off at 290 km/h. Under the new mandate, the electrical power reduction will aggressively begin at just 200 km/h. By the time a driver reaches 300 km/h, standard battery deployment will drop to zero.
Compounding the Downforce Dilemma
This engine restriction adds a fascinating new layer to the Monaco engineering battle. We already know the FIA designated zero active aero “Straight Mode” zones for this track, forcing cars to run heavy, permanent high-downforce setups. Now, coupled with this extreme engine de-rating starting at 200 km/h, straight-line speed is entirely neutralized.
The race will exclusively reward mechanical grip and slow-speed rotation. This severe limitation punishes power-reliant teams like Mercedes while massively playing into the hands of Ferrari, whose chassis inherently dominates in low-speed traction zones.
The battle for pole position will be a pure test of mechanical balance over brute force. With this radical rule change, fans can expect an unpredictable qualifying session where precision matters more than straight-line dominance.
