Lewis Hamilton returns to drive a Ferrari, and for the primary time, he does so aboard the SF-24. Not like the current TPC assessments, which concerned the usage of automobiles not less than two years previous, the continued assessments in Barcelona are a part of Pirelli’s growth program for the 2026 tires, with McLaren additionally collaborating. The automobiles on monitor are 2024 fashions, however in a particular configuration designed to duplicate, as a lot as potential, the traits of subsequent yr’s automobiles.
The 2026 updates
The targets of the check require important modifications to the automobiles, limiting references to the earlier season, and, in Lewis Hamilton’s case, the familiarization with the newest Ferrari. Essentially the most important distinction issues the tires, which have been revised in building and compound, being very completely different from the present ones. For 2026, Pirelli has chosen to proceed with the 18-inch diameter wheels, narrowing the entrance tires by 25 mm and the rear ones by 30 mm. Regardless of this discount, nonetheless, the automobiles in Barcelona don’t function any adjustments to the braking system.
The 2026 tires are designed to work beneath completely different hundreds than the present ones. Particularly, the next-generation automobiles will use lively wings at each the entrance and rear, considerably decreasing aerodynamic load in straights. Nonetheless, Pirelli’s focus is on the stresses skilled in corners when the automobiles shut the wings, transitioning to a configuration with increased aerodynamic load. “We have now targeted our evaluation on the high-load mode, which at present exhibits values about 15% decrease than the present ones,” defined Mario Isola. Therefore, the necessity to conduct the event assessments on the 2024 automobiles in a particular low-downforce setup.
Greater and lighter automobiles
The distinction in aerodynamic load between the intermediate configuration and the low-downforce one sometimes utilized in Monza is about 10%. In Barcelona, Ferrari and McLaren are working with an much more aggressive setup, decreasing the wing profiles as a lot as potential, however not solely that. By elevating the trip top by only a few millimeters, they lose some load, approaching the anticipated values for 2026.
Elevating the present automobiles can be useful to a different objective of the Pirelli assessments. The upcoming rules may encourage groups to make use of floor impact much less aggressively, elevating the ground to work farther from the bottom. “There are completely different opinions about it; work is being completed in sure instructions, but it surely’s nonetheless not utterly clear,” mentioned Haas Technical Director Andrea de Zordo in a current interview for the Italian media. “They in all probability gained’t be as little as they’re now, however maybe not as excessive as they as soon as have been.”
The 2026 automobiles might be taller and fewer inflexible than the present ones, which, working very near the bottom, require robust stabilizing motion from the suspension system. Due to this fact, Pirelli has each curiosity in elevating the 2024 automobiles within the assessments and softening their suspension changes, elements that tremendously have an effect on how forces are transmitted to the tires. One other necessary distinction between the Ferrari and McLaren that fought for the title in Abu Dhabi and people at present testing in Barcelona.
