McLaren shelves revised front wing again as Stella admits concept needs more work

McLaren has parked its revised front wing for a second straight race, reverting to its baseline specification for the Monaco Grand Prix after evaluation runs failed to convince the team the concept was ready to race. Team principal Andrea Stella acknowledged the design is moving in the right direction but still needs fine-tuning before it anchors the development path for the MCL40.

Why it matters:

The front wing is not a standalone upgrade but the foundation for a string of subsequent aerodynamic developments McLaren has in the pipeline. Rushing an unproven concept onto the car risked corrupting the data for future parts and sending the development trajectory sideways at a time when rivals are closing the gap. By prioritizing thorough characterization over immediate deployment, McLaren is protecting its long-term performance gains rather than chasing a short-term fix.

The details:

• The team first trialled the new wing during practice in Canada but elected not to race it after concerns over driver confidence and overall balance.
• An updated iteration appeared in Monaco, but Lando Norris’s early end to second practice limited Friday running and forced the engineers to lean heavily on final practice data from both Norris and Oscar Piastri.
• Stella said the wing’s behavior was "very close to the expectation," though a couple of issues first spotted in Canada still needed to be rectified before it could replace the baseline specification.
• Stella noted the component itself was never intended to deliver a massive performance step in isolation; rather, it marks the beginning of a new aerodynamic concept intended to unlock further gains once fully understood.
• McLaren’s subdued Monaco pace — Piastri qualified seventh and Norris eighth — was attributed to a fundamental downforce shortfall and a car concept that favors tyre kindness over the low-energy demands of street circuits, meaning the wing decision was not the sole cause of its underwhelming weekend.

What's next:

Stella confirmed "a few more developments coming for the next races," with the team planning additional trackside evaluation of the new wing at forthcoming events. Once the concept is fully validated, McLaren intends to introduce a cascade of upgrades tethered to its architecture. Stella also emphasized that the team cannot afford to wait for circuit characteristics to flatter the MCL40, insisting the focus must remain on delivering raw aerodynamic and mechanical improvements rather than hoping specific tracks will mask its current deficits.
