McLaren Upgrades and the Return of the H-Wing
McLaren will introduce a fresh aerodynamic package to the MCL40 for this weekend’s Azerbaijan Grand Prix, aiming to maintain recent race-winning momentum across Baku’s punishing street circuit. The upgrade suite includes the return of the team's rotating 'H-Wing'—first run at Monza and shelved in Madrid—specifically configured to cut drag along the 2.2-kilometre main straight.
The package arrives as McLaren project a tight four-way battle at the front among Mercedes, Ferrari, Red Bull, and themselves. After going winless through the opening 10 rounds of the season, McLaren have surged back into contention. Lando Norris has taken three pole positions across the past four events, collecting two victories and only missing a third in Madrid due to an ill-timed Virtual Safety Car.
The Mechanical Demands of Baku
Baku City Circuit presents one of the calendar’s sharpest mechanical compromises: low-drag configuration for top speed past the Caspian waterfront, paired with tight, low-speed turns around the medieval fortress walls. McLaren Chief Technical Officer Rob Marshall highlighted the specific thermal and electronic challenges awaiting the MCL40 setup.


"Energy management and deployment will be particularly important, as will tyre and brake management with the cars arriving at Turn 1 after the long straight with these areas relatively cold," Marshall explained. "Operationally, there is very little margin for error on a tight street circuit. A small mistake can lead to significant repairs, lost track time and resources being diverted away from performance."
With cars reaching terminal velocity before anchoring hard into Turn 1, managing cold front brake discs and tyres after miles at full throttle will be critical to avoiding lockups and wall strikes.
Development Push Despite Championship Deficit
While Mercedes and Kimi Antonelli hold commanding leads in both the Constructors' and Drivers' Championships, McLaren are not easing up on 2026 development. The technical continuity heading into next season provides strong incentive to continue pushing aero development on the current platform.
All new components will undergo evaluation during Thursday and Friday practice sessions before the team locks in final qualifying and race trims for Saturday's Grand Prix.
