Mercedes is preparing another important development step for the W17 after Formula 1’s summer break, but the championship leaders have no intention of copying one of the most complex solutions adopted by their rivals. While Ferrari, McLaren and Red Bull have invested heavily in the rotating rear-wing concept commonly known as the “Macarena wing”, Mercedes appears determined to pursue a less risky route as it looks to protect its advantage through the second half of 2026.
With Formula 1 currently shut down for the summer break, Mercedes can look ahead with confidence to the return to action at the Dutch Grand Prix in just under two weeks. The Anglo-German team holds significant advantages in both championships: 72 points in the Constructors’ standings and 50 points in the Drivers’ Championship. Andrea Kimi Antonelli’s advantage over Lewis Hamilton can be seen in the latest 2026 Formula 1 driver standings.
However, the season remains long, and Formula 1 has repeatedly demonstrated that no advantage is truly safe until it becomes mathematically impossible for a rival to close it.
Mercedes’ recent results show why another W17 upgrade matters
Mercedes has won eight of the 11 Grands Prix held so far, but there has been a small change in momentum. Across the last five races, the Silver Arrows have reached the top step of the podium only twice.
On the numbers alone, Mercedes has therefore experienced a slight dip. Reliability has not always been completely solid, while its main rivals have recovered performance. Ferrari and McLaren in particular introduced substantial upgrade packages at clearly defined stages during the first half of the campaign.
McLaren’s recent development push has been particularly significant, while Ferrari has also chosen to continue attacking the season with a race-by-race development strategy rather than abandoning its 2026 car.
Mercedes has taken a different approach. Confident in the fundamental strength of the W17, the team has been less inclined to make frequent major changes. Its most important upgrade package so far arrived in Canada, where Mercedes introduced a revised floor, new wings and, crucially, modifications to the start software that substantially reduced the losses it had previously suffered in that phase, particularly compared with Ferrari.
Why the strength of the W17 shapes Mercedes’ 2026 development strategy
Bradley Lord, Mercedes Deputy Team Principal and communications lead, recently explained the philosophy behind the team’s approach in comments published by auto motor und sport.
“The wind tunnel produces a certain number of parts every week, and each one is worth a certain amount of lap time, but with the budget cap you have to decide when to bring the components to the track and realise the performance gain. Ideally, an update arrives when a component has reached the end of its useful life anyway. The skill is all in the timing.”
That timing is expected to lead Mercedes towards another important step after the summer break. The objective will be to generate enough additional performance to keep Ferrari, McLaren and the other challengers at a safe distance until the end of the season.
The first test after the shutdown will come at Zandvoort, where Formula 1 returns for the 2026 Dutch Grand Prix weekend. Mercedes’ decisions over when to introduce its next developments could become increasingly important as the championship moves from Zandvoort towards Monza and the remaining rounds.
Mercedes rejects the Macarena wing risk for the W17
According to AutoRacer.it, however, the next phase of W17 development will not include the so-called “Macarena wing”. Mercedes believes the rotating rear-wing concept offers genuine benefits and accepts that, in the medium or long term, it could become necessary to develop its own version because of the significant contribution it can make to reducing drag and increasing top speed.
For the 2026 season, though, Mercedes is not planning to introduce the solution.
The reasoning is understandable. Developing a rotating rear wing has proved extremely complex. McLaren is still working through the concept after preparing its version for Spielberg and using it briefly in Hungary, while Red Bull encountered significant problems that hurt Max Verstappen on two occasions.
Ferrari, despite appearing to be the most advanced team in this area, also required time before it could use the system with confidence during a race. The Maranello team was only able to run it comfortably in competition from the fourth race of the season in Miami onwards.
Mercedes has less need to gamble than its rivals
The key difference is that Mercedes does not currently suffer from a significant straight-line speed weakness. The W17 has demonstrated strong top-speed performance across different conditions, reducing the need for the championship leaders to invest resources in a particularly complicated and potentially unreliable solution.
Ferrari, McLaren and Red Bull are in a different position. They are the teams chasing Mercedes and therefore have a greater incentive to take technical risks in search of larger gains. Ferrari, for example, continues to push its development programme aggressively as it attempts to close the performance gap during the second half of the season.
Mercedes can afford to be more selective. Rather than reacting to every innovation introduced elsewhere, the team can choose when to convert its wind-tunnel gains into new components and attempt to introduce them at the most efficient moment under the budget cap.
The strength of the W17 has given Mercedes that luxury. Its rivals may need bolder solutions to close the gap, but the championship leaders can focus on timing their next development step correctly and avoiding unnecessary technical risks. If the planned post-summer upgrades deliver the expected gain, that more conservative approach could prove just as important as outright innovation in deciding the 2026 Formula 1 title fight.
