McLaren to Trial Experimental Rotating Rear Wing in Austria

McLaren is set to run an experimental rotating rear-wing during Friday practice at the Austrian Grand Prix as the team hunts marginal gains in a tight development race. The Woking squad confirmed the component is an evaluation piece, adding another layer to an aerodynamic arms race already sparked by Ferrari and Red Bull.

Why it matters:

Ferrari and Red Bull have already trialed their own versions of the concept this season, so McLaren's test shows the idea is gaining traction among the frontrunners. With hundredths of a second deciding grid slots, ignoring any potential efficiency or downforce gain is a luxury no title contender can afford.

The details:

• The wing is part of a modest upgrade package focused on the rear of the MCL40, with engineers gathering real-world data before any race debut.
• Technical director Neil Houldey said the team is "looking for every lap time opportunity," stressing that minor refinements matter when margins are razor-thin.
• McLaren may also face wet weather at Spielberg, creating a rare chance to study energy management and power delivery in the rain.
• The test follows an inconsistent opening phase that has left the team chasing greater stability alongside outright pace.

What's next:

Engineers will study Friday's data to decide whether the rotating wing concept has a future later in the campaign. If the results prove positive, the design could move from an experimental curiosity to a genuine weapon in the development war shaping the season.
