McLaren unveils crinkled rear wing upgrade at Zandvoort
McLaren has introduced a new rear wing with a rippled endplate featuring multiple swage lines as part of its Dutch GP development package. The upgrade forms the second phase of a package that debuted in Hungary and targets improved rear airflow management alongside revised bodywork and brake ducts.
McLaren's Dutch GP Development Package
McLaren has introduced a new rear wing assembly at the 2026 Dutch Grand Prix with a striking rippled endplate that features multiple swage lines.[1] The design represents the second phase of a development package that first appeared in Hungary.
The package also includes revised central bodywork and tweaked rear brake ducts.[1] All three elements aim to manipulate airflow at the rear of the car for improved downforce levels.
Formula 1 official reporting confirms McLaren plans to debut the new rear wing assembly and revised central bodywork together at Zandvoort.[2]
Technical Context
The upgrade arrives as part of a broader push that began earlier in the summer. No performance data has been released yet, and the car will undergo initial running in free practice sessions.
The changes focus exclusively on aerodynamic detail rather than major structural revisions. McLaren continues to iterate on rear-end solutions following earlier experimental wing tests at other venues.
