McLaren Reveals Why Shelved Front Wing Found Success in Barcelona

McLaren has explained why its new front wing, abandoned after a rocky debut in Montreal, delivered strong results upon returning in Barcelona. Team principal Andrea Stella confirmed that rapid behind-the-scenes revisions to the end plates and mechanical setup turned a troublesome upgrade into a success, helping Lando Norris to a podium and Oscar Piastri into the points.

Why it matters:

With Mercedes and Ferrari setting the early pace in the 2026 constructors' battle, McLaren cannot afford development dead ends while chasing a 121-point deficit. The turnaround shows that under Formula 1's still-evolving 2026 regulations, understanding how to run an upgrade is just as critical as the part itself.

The details:

• The front wing was introduced in Montreal as part of McLaren's first big upgrade of the season, but Norris finished the session over 1.4 seconds off the pace, forcing an immediate reversion to the old spec.
• Stella said the team needed time to understand exactly what the wing was delivering, prompting revisions that addressed both aerodynamic conditioning and mechanical behavior.
• After updates were rushed through for Monaco and then refined for Spain, the wing returned in Barcelona with strong correlation to factory data, underpinning Norris's third place and Piastri's fifth.

The big picture:

McLaren now considers its first major upgrade package complete and will switch to continuous development across the MCL40. Stella noted that every team on the grid is still exploring fundamentally different directions with the immature 2026 rules, warning that true design convergence likely remains at least a year away.
