McLaren brings long-awaited Hungary F1 upgrade, trials 'Macarena' rear wing

The core of McLaren’s offensive in Budapest revolves around a substantial upgrade package, which includes a redesigned floor and "further other aerodynamic parts." This development effort has been earmarked by the team as its most significant opportunity since earlier overhauls during the Miami and Montreal Grand Prix weekends. McLaren’s senior director of racing, Randy Singh, articulated the team’s immediate objectives: "We have an upgrade package arriving this weekend, and in such a competitive season every development is important so it will be great to gather further understanding on how those parts perform throughout free practice." Singh emphasized the broader goal: "Our aim is to maximise everything we have available, carry positive momentum into the shutdown and put ourselves in the strongest possible position for the second half of the championship.”

Team Principal Andrea Stella previously admitted that the MCL40’s aerodynamic development was two to three months behind its key rivals. This deficit stemmed, in part, from the team’s prolonged focus on the intense 2025 driver title battle and a subsequent shift in its aerodynamic approach for the 2026 regulations. These factors are understood to have diverted resources and attention that might otherwise have been dedicated to the current car’s early-season development. Stella highlighted the progress made in addressing this gap: "The development on the ground has been quite strong for a few months now. This has led to the upgrades we had in Miami and now there will be another round of upgrades which will come in Hungary and then after the shutdown." The Hungaroring, with its tight, twisty layout and emphasis on aerodynamic downforce, presents an ideal proving ground for these critical enhancements.

Beyond the general upgrade package, McLaren will also conduct a highly anticipated trial of its innovative ‘Macarena’ rear wing during Friday’s Free Practice 1 session. This experimental design, characterized by a mainplane that rotates 180 degrees when ‘Straight Mode’ (akin to DRS) is engaged, aims to drastically reduce drag on straights while maximizing downforce in corners. The concept, first publicly debuted by Ferrari during winter testing, has since become a key area of aerodynamic exploration for several teams.

McLaren’s journey with its ‘Macarena’ wing has been marked by a previous delay. The British outfit had initially intended to trial the component at the Austrian Grand Prix. However, issues encountered in the garage during preparations for FP1 prompted the team to withdraw the wing and return it to the factory for further refinement and fine-tuning. This cautious approach underscores the technical complexities and the paramount importance of reliability and safety associated with such a novel aerodynamic solution. Following these additional developments, the revised experimental rear wing is now set for its track debut in Hungary.

It is important to note that the trial in Hungary will be limited to FP1. McLaren has confirmed that the rear wing is "not scheduled to be introduced fully at this or the following race in the Netherlands." The primary objective for the Hungarian test is to gather crucial performance data and validate the design’s functionality and stability under real-world conditions. A successful trial, however, could pave the way for its full deployment later in the season at circuits known for their drag sensitivity, such as Monza in Italy or Baku in Azerbaijan, where the potential for significant lap time gains through drag reduction is substantial.

The introduction of such a radical aerodynamic concept is not without its challenges, as demonstrated by rivals. Red Bull Racing, for instance, experienced a fraught introduction of its own ‘Macarena’ wing earlier in the season. Max Verstappen, the reigning world champion, suffered two concerning spins at Spielberg and Silverstone, which were attributed to the wing’s closure mechanism and the subsequent reattachment of airflow. These incidents highlighted potential reliability and safety concerns, leading Red Bull to temporarily remove the design for the Belgian Grand Prix. Interestingly, Red Bull is also reportedly planning to trial an improved version of its ‘Macarena’ wing as early as the Hungarian Grand Prix, indicating the high stakes and competitive pressure driving this aerodynamic arms race.

McLaren’s season trajectory necessitates such aggressive development. After starting the season in a reasonably competitive position, the team has struggled to maintain pace with the front-runners. Mercedes, in particular, has consistently demonstrated superior performance, while Ferrari has rolled out an impressive series of upgrades that have elevated both Charles Leclerc and Lewis Hamilton into contention for Grand Prix victories. Red Bull, despite its ‘Macarena’ wing woes, has also continued to add significant performance to its RB22 chassis, further widening the gap to McLaren.

This escalating competitive landscape makes McLaren’s upcoming upgrade package and the ‘Macarena’ wing trial particularly crucial. Andrea Stella acknowledged the challenge: "It’s difficult to lean on the range of performance that Ferrari and Mercedes are operating in at the moment, but hopefully as of Hungary we will start to see a bit of an acceleration in our competitiveness." He further elaborated on the team’s long-term vision and its imminent impact: "We have now a clear direction in terms of development, but in some areas of the car it took a couple of months to get it to be realised. So, we should see in Hungary the first results of this approach and then hopefully more and more upgrades for the rest of the season."

The Hungarian Grand Prix weekend thus represents a pivotal moment for McLaren. The success of these new components, particularly the experimental rear wing, will not only dictate the team’s performance for the immediate future but also inform its long-term development strategy. The data collected from Lando Norris and Oscar Piastri’s runs will be meticulously analyzed, providing critical insights into the car’s behavior and the effectiveness of the upgrades. As the grid prepares for the summer shutdown, McLaren aims to leverage these developments to build momentum and reposition itself as a stronger contender in the highly competitive Formula 1 championship.
