McLaren and Ferrari Unveil Upgrades for F1 Dutch GP at Zandvoort
Heading into the late-summer Dutch Grand Prix at Circuit Zandvoort, McLaren is leading an aggressive Formula 1 development push by rolling out crucial rear-end upgrades to its MCL40 challenger. According to official team previews and paddock reports from outlets like Crash.net and MotorBiscuit, the Woking-based squad is bolting on a new rear wing and revised rear brake ducts to complete the aerodynamic package first introduced at the Hungarian Grand Prix.
Completing the Package at Circuit Zandvoort
The strategic timing of this upgrade cycle comes immediately following Lando Norris’s victory at the Hungaroring before the summer break. That triumph was powered by an initial tranche of updates, which notably featured McLaren’s own adaptation of the innovative “Macarena” rear wing—an aerodynamic design pioneered earlier in the 2026 season by Ferrari. As teams grapple with high-speed sections, banked corners, and unpredictable coastal winds at Zandvoort, optimizing the aerodynamic set-up and ride heights across practice sessions remains paramount.
McLaren technical director for applied engineering Neil Houldey emphasized the necessity of rapid validation during track running. “This weekend will see the team introduce further aspects as part of its ongoing development pathway,” Houldey stated in the official pre-race preview. “These parts will be focused on the rear side, to complete the package introduced in Hungary, a new rear wing and new rear brake ducts. The aim will be to validate the new parts quickly, understand their contribution across the weekend and maximize every opportunity available.”

Similarly, the physical toll on modern drivers competing through a demanding 12-race second half requires rigorous physiological management.
Rival Responses in the 2026 Development Race
McLaren enters the Dutch weekend holding strong historical momentum, having secured the last two victories at Zandvoort with Oscar Piastri winning in 2025 and Norris taking top honors in 2024. However, the competitive landscape remains fiercely compressed. Ferrari has similarly pushed forward with its own continuous update plan, aiming to rectify performance deficits from the first half of the campaign. With Red Bull and other front-runners simultaneously introducing aerodynamic adjustments, Houldey acknowledges that reliability and execution will dictate who breaks out of the midfield logjam.
“We have learned a lot in the first part of the season about how this car needs to be driven to extract performance and on containing the issues we faced earlier in the year,” Houldey noted. “We know other teams will bring developments too. Therefore, it will be another tough event, and our focus is on getting everything we can out of the car.” As data logging commences through Friday practice, the battle to extract consistent aerodynamic efficiency from the 2026 ground-effect regulations will set the baseline for the remainder of the championship hunt.
