Norris traces lost speed to fuel-system trouble. McLaren believes it has found the cause. Singapore will provide the first test.
Lando Norris says a fuel-system problem has hurt his pace in recent Formula 1 races, costing him straight-line speed against McLaren team-mate Oscar Piastri. The team believes it has identified the fault, but Norris will not know whether its fix works until he gets the car on track in Singapore.
The timing matters: the issue surfaced during a tight fight in which small qualifying gaps have carried a hefty price. Norris says it played a part in starting fifth at each of the last two rounds, after taking pole at Hungary, the Netherlands and Madrid. He won in Hungary and the Netherlands, and came close to victory in Madrid, but says recent lost speed has narrowed his options. Marina Bay’s short straights may blunt the benefit of a repair, yet the underlying question reaches beyond one circuit: can McLaren restore the car’s expected engine performance and protect its race reliability?
Norris says straight-line speed deficit has hit recent qualifying
Norris described two frustrating weekends spent trying to understand why his car repeatedly lacked speed on the straights. In qualifying, he estimates the deficit has cost him two or three grid places in each of the last two events—positions that can shape the opening stint before strategy has room to respond.
The imbalance was particularly irritating because the car could leave corners strongly, only for rivals to pull away down the following straight. That points to a performance loss between corner exit and the end of the acceleration zone, though McLaren has not publicly detailed the precise fault or its effect on power delivery.
Fuel delivery fix awaits its first track test
A fuel-system fault can disrupt how consistently a power unit receives fuel, but the available details do not confirm the specific mechanism behind Norris’s problem. The distinction matters: identifying a suspected cause is not the same as proving that a repair restores full performance under qualifying and race conditions.
Norris says the team has put substantial work into investigating the issue and he is hopeful the car will improve. He also accepts that his own execution can improve, rather than attributing every lost position to the hardware. The first running in Singapore will turn the team’s diagnosis into measurable evidence.
Singapore offers a limited but telling test for McLaren
Marina Bay’s layout gives the repair a less demanding proving ground than circuits with long full-throttle sections. Norris noted that straight-line speed carries less weight here, so the Singapore result may not reveal the full scale of any improvement. Still, a car should accelerate as expected wherever the lap demands it.
The weekend’s data will help separate the system fault from other factors, including setup and driver performance. McLaren can compare Norris’s speed traces with Piastri’s and check whether the gap changes across acceleration zones, while watching fuel use and power delivery over a race stint. Those comparisons matter for both immediate race results and the championship points at stake in a close intra-team battle.
