The McLaren Formula 1 team has announced it will bring a new set of upgrades to the Dutch Grand Prix, set to take place this weekend at the historic Zandvoort circuit. The news was confirmed by the team on their social media channels on Wednesday, August 19, 2026, and later detailed by the specialized motorsport outlet Last Word on Sports.
Under the leadership of team principal Andrea Stella, McLaren continues to develop the MCL40, the car competing in the 2026 season. The team showed significant progress at the Hungarian Grand Prix, where they debuted their largest upgrade package of the year. Now, at Zandvoort, they will complete that evolution with a new rear wing and new rear brake ducts.
What Are Brake Ducts and Why Do They Matter?
Brake ducts are aerodynamic components that manage airflow around the brakes, helping to cool them while also influencing the car's overall aerodynamic performance. In modern F1, these parts are crucial for optimizing downforce and reducing drag, making them a common area for development upgrades.
Consolidating Progress and Chasing the Leaders
McLaren's Director of Applied Engineering, Niel Houldey, explained that the team has learned a great deal in the first part of the season about extracting performance from the car and managing the reliability issues that plagued them for several months. “We have worked hard on continuous development, with some parts available this weekend, focusing on the rear of the car, to complete the package introduced in Hungary with a new rear wing and new rear brake ducts,” he said.
Houldey also acknowledged that other teams will bring their own updates to Zandvoort, making for a demanding race. “Our goal is to extract everything we can from the car. If we execute well, we can get into the fight with the leading teams,” he added.
The Championship Battle: Mercedes, Ferrari, and McLaren
In the Constructors' Championship standings, Mercedes holds a considerable lead, but on track, the competition is much tighter. Both McLaren and Ferrari are closing the gap to Mercedes' W17, with Ferrari benefiting from improved reliability. McLaren, on the other hand, suffered multiple retirements due to reliability problems in the first half of 2026, costing them valuable opportunities.
The British team has also had to learn how to maximize the potential of the Mercedes power unit, both in terms of horsepower and electrical efficiency—a process that left them feeling they were playing catch-up. However, the internal feeling is that these foundational obstacles are now better understood, allowing them to focus on pure performance.
A Promising Development Path
The key to these new parts is not just the performance they bring, but also finding the ideal operating window. At Zandvoort, McLaren will have two tasks: confirming the data from Hungary (which they analyzed during the summer break) and incorporating the next phase of their development, which could be central to their aspirations of fighting for wins consistently.
With 12 races still remaining in the 2026 season, McLaren is optimistic and confident that these upgrades will allow them to make the definitive leap in the fight against Mercedes and Ferrari. The Dutch Grand Prix takes place this weekend at the Zandvoort circuit, a challenging track known for its banked corners and narrow layout, and will be a key test to see if the MCL40 confirms its progression.
