The 'secret' of the Scuderia was having a lot of aerodynamic downforce, generating less drag and therefore managing the tyres optimally. An update in the wheel area also contributed to this, helping the SF-26 improve its rear tyre management. The excessive heat did not work in Mercedes' favour — they remain the reference package, the most complete one, but with significant battery issues that are requiring further performance-related fixes compared to the start of the season. Conversely, some modifications under the hood of the SF-26 have allowed the Maranello team's engineers to reduce air outlets compared to the start of the season, running in qualifying and the race with a rather closed and highly efficient engine cover. It is no coincidence that, between aerodynamic updates, a more efficient car body, and Mercedes' reliability problems, the SF-26 did not fall too far short at Montmeló from a power unit standpoint. And if the engine gap narrows, the strengths of the SF-26 project come to the surface, giving Hamilton — for now — the ability to consistently fight for the podium and capitalise on opportunities like the one that came his way in Spain to take the win.

Ferrari played an ace of their own at Montmeló: on the SF-26's rear axle, they debuted the new BBS Japan wheels. From this year, in fact, the FIA has returned to liberalising wheel design, after a period during the ground effect era when they all had to be identical.
The International Federation's regulatory opening has reignited research into wheel rims: the teams wasted no time in developing wheels that can contribute to performance. Key factors are stiffness, weight, and more recently the ability to manage temperature during a race stint in order to stabilise pressure and, consequently, control tyre wear.
While Mercedes took advantage of OZ Racing wheels to warm up the tyres in Canada, Ferrari benefited from the new rear wheels to insulate the heat produced by the braking system and prevent the high temperature from being transferred to the tyres through heat radiation from the rim. The Prancing Horse's technicians carried out very thorough work alongside those at BBS Japan: while in Maranello they developed the brake ducts so as to create a layer of cool air between the two carbon walls — with ventilation designed specifically using air intakes that have nothing to do with those for disc and caliper cooling — the wheel suppliers evolved the forged magnesium wheels with a design that allows heat to be dissipated, preventing temperature from being transferred to the tyre.
