Monza had been waiting 60 years for an Italian winner. Kimi Antonelli started 19th and ended that wait in 53 laps and had the pace to make his way through the field.
The data give a good measure of the performance behind the comeback. Mercedes had the strongest race-pace distribution of the field, with a team median around 1:25.4, roughly half a second ahead of Red Bull and around 0.6–0.7 s clear of Ferrari and McLaren. Antonelli’s violin is shifted towards the fastest end of the field, with a large concentration of laps between the mid-1:24s and mid-1:25s. His pace during the first stint was superb, but also the tire switch under VSC conditions was decisive.
Indeed, he started on Hard, switched to Medium after the early red flag and then, under the Lap 29 VSC, Mercedes gave him another fresh set of Mediums. Russell went the other way, with the Hard fitted during the stoppage staying on his car until the chequered flag.
Tire degradation at Monza was remarkably low despite track temperatures above 50°C. Long straights gave the rear axle plenty of thermal recovery between traction events, while the amount of graining varied quite significantly depending on the car and stint management. Several drivers actually completed around 50 laps on a single Medium or Hard set.
Antonelli’s extra stop was therefore more about exploiting the VSC window than responding to a tire that was falling away. The reduced pit-loss allowed Mercedes to give him fresher tires and more performance for the final part of the race.
The fuel-corrected trends make it clear. From roughly Lap 30 to the finish, Antonelli’s fitted pace increases by about 0.9 s, with a slope not dramatically different from Russell’s. The main difference is the offset between the two curves: the fresh Medium starts that stint around 0.8–1.0 s/lap quicker than Russell’s much older Hard. That advantage progressively brought Antonelli onto his teammate before the pass on track.
Antonelli crossed the line 3.8 s ahead of Russell, 14.7 s ahead of Verstappen and about 19 s ahead of both McLarens. From P19, after 26 overtakes. Admittedly, the VSC gave Mercedes a useful strategic opportunity, but Antonelli’s underlying race pace had already put him in a position to exploit it.
