What Formula 1's Ground-Effect Rules Actually Changed About Racing

Did the Rules Actually Produce Closer Racing?

By the metric the rules were designed to move, the answer is yes, measurably. Across the 2021 season, cars completed 599 genuine on-track overtakes, counting only passes that did not involve pit stops or mechanical retirements. In 2022, over the same 22-race calendar length, that number rose to 785, a 31 percent increase. Pirelli's own internal tracking, using a slightly different counting method, arrived at a similar conclusion, reporting roughly a 30 percent rise in overtakes from 2021 to 2022.

Race broadcasts from that season reflected the shift qualitatively as well as statistically: multiple cars racing wheel to wheel for several laps at a stretch, trading positions more than once in the same corner, became a regular occurrence rather than an occasional highlight. That said, the same season also produced a wider performance gap between the fastest and slowest teams than 2021 had, since ground-effect floors turned out to reward precise aerodynamic development even more than the previous wing-based rules did, meaning closer racing between similarly matched cars did not necessarily translate into a tighter overall field.
