The 2-day Pirelli take a look at for the event of 2026 tires has concluded in Barcelona. The session featured the 2023 McLaren and the 2024 Ferrari in a particular configuration to copy the anticipated aerodynamic load underneath the upcoming rules, which will probably be 15% decrease than the present one. Evaluating the lap instances with these from the latest Spanish Grand Prix qualifying might sound logical, however paradoxically, the over 3-second deficit truly strengthens expectations that efficiency will probably be very shut between the 2 generations of automobiles. Right here’s why.
The Comparability
The quickest lap of the session was set by Charles Leclerc, whose 1’14’’971 was 3.2 seconds slower than his greatest time within the final Spanish Grand Prix qualifying, regardless of utilizing the identical automotive however with wider tires and considerably increased aerodynamic load. Nevertheless, a fairer comparability for 2026 ought to be with the primary 12 months of ground-effect rules, 2022. A direct comparability is inconceivable, as on the time, Barcelona nonetheless used the previous circuit format, together with the ultimate chicane.
Over the previous three years, lap instances have typically improved by 1.5 seconds, with some variations relying on the monitor, making it doable to approximate the perfect lap from the newest Pirelli take a look at as being 1.5 to 2 seconds slower than 2022 efficiency. Nevertheless, this stays a tough estimate that wants correct context, contemplating variations in environmental circumstances and, most significantly, testing applications. Moreover, as is customary in Barcelona, Pirelli examined the toughest compounds of the longer term 2026 vary—C1, C2, and C3—however it’s unclear whether or not Charles Leclerc’s lap was set on the softest out there compound, though that’s possible.
The Non-Simulatable Components
Efficiency variations between present and future automobiles is not going to be uniform throughout all tracks. Excessive-downforce circuits like Barcelona will penalize the lower-downforce 2026 automobiles essentially the most, whereas on different tracks, they are going to be nearer to present lap instances. Lowering aerodynamic load by 15% just isn’t sufficient to completely replicate the traits of the next-generation F1 automobiles, which will probably be considerably quicker on the straights, even with out contemplating the twin lively aerodynamics on the entrance and rear. The general width will lower from 2 to 1.9 meters, enhancing aerodynamic effectivity, however extra importantly, ground-effect efficiency will probably be lowered. At the moment, the ground generates extreme downforce on the straights, resulting in pointless drag. “At the moment, aerodynamic load comes primarily from the ground. The quicker you go, the extra downforce you generate, to the purpose the place it paradoxically turns into ineffective on the straights,” defined Mario Isola.
On high of this, the minimal weight may even be lowered, with the next-generation automobiles anticipated to be about 30 kg lighter. The narrower tires used within the newest Pirelli take a look at saved 4-5 kg, together with just a few kilograms faraway from different components of the automotive. Nevertheless, it’s unknown how a lot Ferrari and McLaren have been capable of lighten their automobiles, given the present challenges in even reaching the 798 kg minimal weight. This implies further lap time variations in an estimated comparability with precise 2026 automobiles.
General, the scenario doesn’t seem alarming. Quite the opposite, when correctly contextualized, the Barcelona lap instances lend credibility to Nikolas Tombazis’ assertion from final November: “Concerning lap instances, we count on them to be very near these of this era of automobiles.” Nevertheless, the efficiency of the brand new energy models stays the largest unknown within the equation of the brand new rules.
