Mercedes sees 2026 F1 regulations as “like chasing a moving target”

The ground effect generation of Formula 1 cars is living its final chapter, as the sport prepares for the huge regulation changes set to arrive in 2026. The overhaul will affect both the chassis and the power units. With seven races still left on the current calendar, no major updates or revolutions are expected, since most teams are already shifting their full focus to next year — a season that looks increasingly complex. Engineers are continuing their work on simulations, and from time to time new details and challenges emerge.

A clear example is the development of the active front wing, which has been at the center of debate between the FIA and technical departments due to safety concerns. After months of discussions, the first prototype was completed in July. Ferrari was the only team to bring a mule car fitted with this configuration to the track, running it during the Pirelli test at the Hungaroring.

Andrew Shovlin’s comments

The obstacles hidden behind every piece of data make it difficult for engineers to get a clear picture of how the future cars will behave on track. Andrew Shovlin explained to Motorsport: “The car evolves from week to week, and when its performance changes, the simulator changes as well. For this reason, we are already trying to estimate the downforce levels we will have four months from now, because it makes no sense to focus on something that will never actually make it to the track. Trying to balance the chassis with the engine is like chasing a moving target.”

All forecasts for the 2026 season remain shrouded in uncertainty, and not even speculation exists on which team might be ahead of the others. The first track debut will be a surprise for everyone. To support the designers, the FIA has confirmed three pre-season testing sessions. The first will take place in Barcelona at the end of January, followed by two weekends of running in Sakhir. Still, the Mercedes trackside engineering director does not expect massive performance gaps. “We are all developing our cars in isolation. Nobody knows anything, and even we have very little information about our rivals. Given the way the rules are written, there will not be huge gaps when testing begins. It will be similar to the current situation, where you cannot distinguish one car from another except for the livery. Some aspects are too restricted, there is not much freedom, and only when the limits are understood will the fine details be refined,” added Shovlin.
