FIA Mandates Active Aero Ban and New “Rev1” Engine Map for Monaco Grand Prix
The FIA has mandated strict technical interventions for the upcoming Monaco Grand Prix, Motorsport reports. Alongside a total ban on active aerodynamics throughout the principality, a specific engine mapping known as «Rev1» will be introduced to restrict top speeds by forcing the MGU-K to deploy its electrical power differently.
Monaco remains one of the most iconic fixtures on the Formula 1 calendar. However, the introduction of the latest technical regulations means the sport’s governing body has had to rethink how the new generation of cars tackle the unforgiving street circuit. These sweeping changes are designed to prioritise safety by altering how teams manage their vehicles through the narrow barriers.
Ban on active aerodynamics
The most immediate change is the complete restriction of active aerodynamics. Unlike last year when the drag reduction system was permitted on the main pit straight, drivers will not be allowed to open their wings during qualifying or the race.
The FIA generally defines activation zones only on stretches where a car is not operating at the absolute limit of its grip. This ensures that the tyres are not subjected to maximum lateral or traction loads. The overarching goal is to guarantee that the wings can be opened safely without unsettling the car, even at the end of a stint on heavily worn rubber.
Furthermore, the FIA stipulates that an activation zone must last for a minimum of three seconds. Anything shorter would simply increase the driver’s workload without offering any tangible benefit to lap time or fuel conservation.
Last year, drivers deployed the movable wing on the start straight for just over five seconds to reach speeds of around 290 km/h. Given that the new 350 kW electric motors provide significantly greater acceleration, the FIA deemed the aerodynamic deployment unnecessary.
Scrapping the straight-line mode completely neutralises the risk of cars arriving too fast into the heavy braking zone at Sainte Devote, which features a notorious bump and extremely limited run-off space.
Introduction of «Rev1» engine map
To further bolster safety, the FIA is not relying on aerodynamic restrictions alone. Taking into account the sheer output of the new electrical power units, officials have mandated a bespoke «Rev1» engine map for the event. This introduces a strict alternative power curve for the MGU-K.
The objective is twofold: to prevent excessive top speeds in high-risk areas such as the pit straight, the climb towards Casino Square and the tunnel section whilst simultaneously reducing approach speeds into critical corners.
While the maximum power output will remain untouched at 350 kW, the derating phase, where electrical power is gradually reduced, will be radically altered.
Standard Grand Prix Derating:
- Up to 290 km/h: Full 350 kW deployment
- At 310 km/h: Power drops to 250 kW
- At 345 km/h: Power drops to 0 kW
Monaco Grand Prix «Rev1» Derating:
- Up to 200 km/h: Full 350 kW deployment
- At 270 km/h: Power drops to approximately 100 kW
- At 300 km/h: Power completely cuts out (0 kW)
Fortunately for the teams, Monaco is not a track that strains energy consumption. The circuit features numerous heavy braking zones that allow the battery to harvest energy efficiently, meaning drivers will not be forced to resort to fuel-saving lift and coast techniques.
The overtake mode has also been adjusted to suit these new parameters. At a standard race, this mode allows the MGU-K to maintain its full output up to 335 km/h before zeroing out at 355 km/h. In Monte Carlo, the overtake setting will still begin its derating phase at 200 km/h but the reduction curve will be significantly less aggressive than the standard Rev1 map.
