2026 Power Battle: Who really won the regulation change?

The 2026 regulations introduced a lot of change in Formula One from the previous 2025 season. Not just due to the changes to the cars themselves, but it completely changed the competition order.

Let’s get into it.

What the new regulations brought

Aerodynamic efficiency

The wheel base has been decreased by 200mm (3600mm to 3400mm), the maximum tyre width by 100mm (2000mm to 1900mm), and the minimum weight has been decreased by 30kg (798kg to 768 kg). Tyre diameter stayed the same, while the front wheels have been reduced by 25mm in width and the rears by 30mm.

Downforce has been reduced by 30%, and drag by 55%. Adjustable front and rear wings took the place of DRS, providing high and low downforce.

Power efficiency

Power from the hybrid unit has dropped from maximum 560kw to 400kw, but the battery element has risen almost 300% from 120kw to 350kw. The amount of energy recuperated while braking has increased to 7MJ per lap (originally changed to 8.5MJ but reduced to 7MJ after Japan).

The goal for these changes

Formula One is trying reduce their carbon footprint by hitting net zero by 2030. The FIA stated that the goal was for a more “agile, competitive, safer, and more sustainable car.”

The reason they got rid of the MGU-H component was because it was not attracting manufacturers as it was too complex and expensive to build. Now with the weight being lower, the cars are faster. This means faster corners and straights. Fast racing brings more revenue into the sport with more people watching, and more sponsorships coming in.

Complications from these changes

So far, the power units have been quite unreliable, with someone out due to problems every race. Drivers are having to face more cognitive demands. This is because the power unit requires a strategic plan every lap, managing the power unit and the tyre simultaneously. A new plan has to happen every lap.

There is also the safety concerns when it comes to the speeds. The FIA recently adjusted the power unit charge after Ollie Bearman’s 50G crash in Japan. We have yet to see how that effects racing in Miami this weekend.

So, who has it down?

Right now the top contenders are Mercedes AMG and Scuderia Ferrari. Both have fast cars, but different strategies.

Mercedes AMG

The silver arrows W17 has been the top car this season. The W17 features a “slotted diffuser” for an enhanced underbody downforce. It also has a push-rod suspension system, this lowers the center of gravity—enhancing stability and handling. Mercedes has the advantage of using fuel provided in their partnership with PETRONAS, design specifically for their complex car.

This far in the 2026 season, Mercedes has shown that they already have a pace advantage. The advantage could be due to their easy handling, or because the drivers are comfortable with the new engines. Both George Russell and Kimi Antonelli have had struggles with their front wings, which causes them to lose significant pace.
