McLaren to Continue MCL40 Upgrade Push Following Baku Validation

McLaren is continuing its development path for the MCL40 despite a points-less weekend in Azerbaijan. Team Principal Andrea Stella has confirmed that while the primary focus has now shifted toward the 2027 challenger, a "tail of parts" previously signed off will still arrive trackside to refine the current car's performance.

Why it matters:

In the high-stakes environment of the 2026 season, maintaining marginal gains is critical. Even as teams pivot toward future regulations, validating aerodynamic concepts on the current car prevents a late-season performance dip and provides essential data for the next generation of chassis.

The Details:

• Technical Updates: The Baku package saw the reintroduction of the 'H-Wing' rear wing concept, alongside several other aerodynamic refinements aimed at increasing overall efficiency.
• Performance Data: Despite the lack of points, Stella noted that the upgrades successfully added lap time. The lack of visible impact in Baku was attributed to the circuit's specific corner profiles rather than a failure of the parts.
• Race Setbacks: The potential of the upgrades was masked by misfortune; Lando Norris was sidelined by a collision during a Safety Car restart, and Oscar Piastri lost a strong podium position following a late-race lock-up.
• Collateral Damage: The collision involving Norris resulted in the loss of several newly introduced components, necessitating the use of backup parts for upcoming events.

What's next:

McLaren will integrate the remaining pre-approved upgrades over the final stretch of the season. While the engineering priority is now firmly set on the 2027 car, the successful validation of the Baku package ensures the MCL40 remains competitive as the 2026 season unfolds.
