Mercedes reveals it assessed a rotating rear “Macarena” wing more than a year ago but parked the idea, with deputy technical director Simone Resta citing an unfavourable drag‑versus‑downforce trade on a recent team broadcast.

The concept rotates the main flap in a straight‑line mode to cut drag and lift top speed. Ferrari pioneered the approach, with Red Bull and McLaren conducting their own tests as the idea spread through the pitlane.

Resta says Mercedes’ simulations show the device reliably trims drag, but it also triggers a downforce deficit any time it runs in open mode. That persistent loss undermines overall performance across sessions.

He indicates the engineering effort and manufacturing complexity were not justified at the time. However, Mercedes keeps the option open and continues to benchmark rival solutions as the competitive picture evolves.

That caution comes amid championship momentum. Mercedes leads the constructors’ standings on 578 points, 134 clear of Ferrari, while Kimi Antonelli holds a 102‑point cushion over George Russell heading into Austin.

Development focus remains on coherent package gains rather than headline straight‑line tricks. The team split specifications in Singapore, then Toto Wolff confirmed the latest updates will be installed on both cars for the United States Grand Prix, targeting upgrades that improve overall package performance.

The wider regulatory backdrop also matters. With the concept attracting attention, the balance of risk could shift if an FIA clampdown on the Macarena wing tightens interpretations around moving aerodynamic devices.

Track profile and set‑up windows further shape the decision. Gains on the straights must outweigh time lost through corners and stability compromises, especially with tyre management and DRS effectiveness varying circuit to circuit.

For now, Mercedes prioritises predictable aero characteristics over transient straight‑line gains, a theme consistent with its recent experiment work and incremental updates. The team remains ready to revisit the rotating wing if the cost‑benefit picture changes.

With rivals iterating rapidly, the technical arms race is set to intensify through Austin and beyond, ensuring continual reassessment of high‑payoff concepts such as the rotating rear wing.
