James Allison, Mercedes technical director, revealed the scale of the team’s development pace in the new era of Formula 1. According to the engineer, the gains recorded in the wind tunnel are about six or seven times greater than those observed last season.

The radical change in regulations between 2025 and 2026 accelerated the evolution of the cars and allowed small updates to produce significant effects on performance. This also contributed to frequent changes in the competitive order, with teams managing to change their grid positions throughout the championship.
“One of the defining characteristics of this regulation cycle is how immature they still are,” Allison said on the Nu Silver Arrows podcast. “The development rates are huge compared to previous years. On the aerodynamic side, the rate of gain we are seeing in the wind tunnel is approximately six or seven times greater than last season.”
The Mercedes technical director estimated that this pace represents approximately half a second of gain every two months. For the team, the strategy adopted before the start of the season was to maximize this development curve, anticipating the development of the initial car.

“We made a conscious decision before the season to push the first car harder than we had before. We left things later than usual, and effectively, we built a program with almost no contingency margin,” Allison explained.
The choice allowed Mercedes to arrive at the first race with a very competitive car, but it also brought a consequence. The team consumed much of its development potential early, while rivals who finished their projects earlier were able to start working on updates sooner.
“They have been introducing updates while we were rebuilding our development line,” Allison concluded. As teams are achieving gains at similar rates, the competitive scenario can change quickly, and Mercedes intends to maintain the lead while awaiting its next wave of updates.
