HONDA The Power of Dreams

The 2026 Formula One season introduces major changes to the cars, fundamentally altering how they are driven and how races are managed. The introduction of active aerodynamics and an overtaking mode is expected to reshape the balance between attack and defense for drivers.

Among the various changes, the new power unit regulations are likely to have one of the greatest impacts on how the cars perform and how races unfold. Managing electrical energy will become a central element of performance. Generating energy efficiently and deploying it effectively will be one of the biggest challenges in extracting speed from the new cars.

With the output of the internal combustion engine (ICE) and the electric motor now contributing roughly equal proportions of total power—and with the removal of the MGU-H, which previously served as a major energy-generation device—F1 cars will operate under constant pressure to manage electrical energy.

Energy recovered during driving through the MGU-K regeneration system is limited to a maximum of 8.5 MJ per lap, with up to an additional 0.5 MJ available under certain conditions. Within this limit, teams and drivers must determine where and when to deploy electrical power to achieve the greatest performance advantage.

Because the electric motor accounts for a larger share of the car’s output, a shortage of electrical energy can result in a noticeable loss of speed. If too much energy is used at a decisive moment, the car may later enter a situation where energy reserves are depleted, forcing the driver to prioritize energy generation.

Particularly over longer race distances, the challenge will not only be racing competitors on track but also managing how electrical energy is generated and used throughout the race. Teams and drivers will need to balance performance and energy management at all times.

This strategic interaction with electrical energy is expected to be one of the defining elements of the 2026 season. With information such as energy recovery status and battery levels becoming more visible, spectators gain greater insight into the condition of the car and the decisions being made by the driver.

Moments such as full-power overtaking attempts, sudden drops in pace due to depleted energy reserves, or the engine running at high revs to generate electrical energy even at lower speeds will create race situations that differ from previous seasons. Each of these moments could have a significant impact on race results and championship standings.

Drivers will therefore need not only speed, but also a new level of strategic awareness. The balance between driving performance and energy management may become a key element in shaping the outcome of races throughout the season.

To help fans better understand what is happening during races—and to enhance safety—new regulations introduce additional lighting systems that indicate the condition of the car. Understanding what these lights represent can provide additional context while watching a race. The following is a brief overview.

One newly mandated system is the lateral safety light, which is integrated into the mirrors on both sides of the cockpit. These lights are designed to be visible from multiple angles and under a wide range of weather conditions.

The lights illuminate when a car comes to a complete stop or when its speed falls below 20 km/h. They may also activate if a car remains stationary on the grid at the start while still in neutral. Once the driver engages a gear, the lights turn off.

Rear lights, which were traditionally used primarily to improve visibility in wet conditions, now operate together with lights mounted on both ends of the rear wing to improve visibility to following cars.

In addition, these lights indicate the operating status of the Energy Recovery System (ERS). When MGU-K deployment ends and the system switches to energy recovery—causing rapid deceleration—the rear lights flash rapidly in red to warn following drivers. This function helps reduce the risk of rear-end collisions by signaling the sudden change in speed.

Even when the car is running at full throttle, there are situations where the system forces the internal combustion engine to generate electrical energy. This condition is sometimes referred to as “super clipping.”

Rear lights will also continue to illuminate or flash in certain situations, such as when the pit-lane speed limiter is engaged, when wet-weather tires are in use, or when the engine stalls.

A new function has also been introduced in which the rear light illuminates in blue-green. This indicates that a less-experienced driver—such as one participating with a Free Practice-only Super Licence—is on track, alerting other competitors to the situation. In this case, only the main rear light is illuminated, while the rear-wing lights do not activate.

In terms of safety, an impact warning light has also been introduced. Installed above the cockpit, this light works in conjunction with the accident data recorder and alerts the medical team when a significant impact occurs. If forces exceed a certain threshold, the light activates to indicate that the driver may require immediate medical evaluation.

During the early races of the season, teams and drivers will likely still be exploring the best ways to manage the new cars and systems. As the season progresses, however, teams that discover more effective approaches to energy management and driving strategies may begin to demonstrate a clear performance advantage.

The uncertainty that accompanies the first year of a new set of regulations also means that the competitive order could shift from race to race, depending on circuit characteristics and how well each team adapts to the new demands.
