McLaren is preparing to replace fuel‑system components in an attempt to eradicate a persistent fuel injection issue that has stunted its straight‑line pace.
Speed Barriers at Baku
During qualifying at Baku, Lando Norris suffered a notable drop in top speed compared with Mercedes‑shared engines, revealing a flaw in the fuel delivery. The short, high‑G straights exposed the problem, diluting McLaren’s performance against rivals.
Despite intrinsic car weaknesses, the driver’s marginally slower car was attributed to the injection glitch, explaining a two‑ to three‑position loss from the other top four teams.
Ongoing Race‑Day Impact
The issue surfaced sporadically in the actual race and also touched Oscar Piastri’s machine, though to a lesser degree. This recurring problem carried over into Bahrain and Malaysia, where the team’s pace suffered on the demanding Sepang track.
McLaren’s technical crew, however, has outlined a plan to modify ancillary power‑unit components, including the fuel system, during the Singapore FP1 session.
Driver Lando Norris expressed frustration but remained hopeful, stating the team had invested considerable effort to untangle the problem and that the next FP1 test would reveal improvements.
Singapore FP1: The Decisive Probe
Singapore offers a circuit where straights are less critical, yet McLaren cannot afford any deficit in a close four‑way contest. A successful resolution here would confirm that the lack of power in Malaysia was not a one‑off irregularity and that the MCL40’s aerodynamics were losing ground on an uneven racing surface.
“You must run the straights as fast as possible, and any loss breeds a slower exit from corners,” Norris explained before Friday’s session. He acknowledged the team’s dedication and expressed confidence that the upcoming data would validate the remedial work.
With the revised fuel system now field‑tested, McLaren’s next objective will be to restore straight‑line speed and secure a competitive position in the midfield battle.
