Lando Norris arrived in Baku on the back of a golden run against Oscar Piastri, but qualifying for the Azerbaijan Grand Prix turned that story on its head. A technical issue robbed his McLaren of straightline speed, and the Norris Baku top speed shortfall left him fifth on the grid, three tenths behind his team-mate in Q3.
That gap matters. Norris had outqualified Piastri nine times in their previous ten sessions this season. Baku broke that pattern badly, handing him his largest qualifying deficit of the year. Losing out to a car problem rather than a driving error stings in a different way. It also pointed to two separate explanations, one specific to his own car and one shared by the whole team. Team principal Andrea Stella addressed both after qualifying: an isolated fault on Norris’ McLaren, and a broader straightline deficit that affected the whole team in Baku.
Qualifying Setback Leaves Norris Facing Baku Uphill Battle
A fifth-place grid slot is a poor return for a driver who has spent most of the year setting the pace over one lap against his team-mate. Norris knew it too. The frustration was obvious as soon as he climbed out of the car, and it centred entirely on power rather than pace through the corners.
“There’s more in my car for some reason than the other car,” he said, pointing directly at Piastri’s identical machinery parked on the other side of the garage. He added: “So we have to understand why I’m basically having to push more than Oscar to try and make up for my straightline speed.”
That is a driver explaining, in plain terms, why he had to carry extra risk through the lap just to stay in touch. Nine wins from ten head to head with Piastri became one defeat that had nothing to do with how he drove the car.
Fuel Injection Glitch Creates Isolated Power Deficit
Stella confirmed the team had traced a specific fault on Norris’ car rather than a wider concern. “On Lando’s side specifically, we observe a deficit of power that we are investigating,” he said, as detailed in Motorsport.com’s analysis of McLaren’s straightline speed.
He pointed to the fuel system as the likely culprit. “It seems to be linked to some behaviour of the fuel injection, something that hopefully we, or the adaptive systems, should be able to improve for tomorrow.”
Stella was careful to separate this from any wider worry about the power unit itself. “It looks that occasionally the power unit generates a bit less power, but this is a specific phenomenon, a specific issue. It has nothing to do with the overall behaviour of the power unit.” This was not a structural flaw in the engine McLaren shares with Mercedes. It was a localised glitch on one car, on one weekend, that the team believed it could fix.
Telemetry Reveals Telemetry Disparity Across McLaren and Mercedes
The telemetry backs up what both driver and boss described. Norris’ top speed in qualifying trailed Piastri’s, a clear gap on a track built around long straights and late braking zones. That shortfall alone explains much of his deficit in Q3.
The wider picture is more revealing again. George Russell’s Mercedes ran faster through the same speed traps than both McLarens, comfortably clearing Piastri and Norris alike. That gap matters at a circuit where straightline speed shapes both qualifying position and overtaking chances. The Norris Baku top speed deficit was really two problems layered on top of each other: a specific fault on his own car, and a broader gap to Mercedes affecting both McLaren drivers equally.
Stella addressed the second point directly. “In a circuit like this, we have seen in every practice session and then in qualifying that we were losing time in the straight compared to Mercedes.” Even without Norris’ individual issue, McLaren knew it was giving speed away all weekend.
Aerodynamic Efficiency Challenges Ahead for Low-Drag Tracks
Norris was asked whether McLaren’s shortfall to Mercedes came down to how the shared power unit was used, or to aerodynamic drag. His answer covered both. “It’s both. They have a very efficient car, they always have done for years. We need to take a big step in that direction if we want to be competitive in any straightline-speed track for the rest of the season.”
Stella gave the technical detail behind that view. “While we have the same power unit, there’s a few differences, and I think it’s fair to say that their package, chassis, ratios, power unit itself, it just seems to be more effective when it comes to generating top speed. We saw how strong they were in Monza, pretty much in every long straight in the championship they were able to generate more speed.”
He was careful not to point at how Mercedes uses the shared engine. “It would be incorrect from an engineering point of view to say that there’s a difference in power unit or they use the power unit a little bit better, because in fact we don’t know and we are not assuming that there’s any difference.” Instead, Stella pointed at the whole car. “It’s the package that is more effective for them, like they might have even less aerodynamic drag; we know that drag is an area that we need to keep working on. As a fact, we think it’s an opportunity to do better.”
That leaves McLaren with two separate jobs before the next low-drag circuit arrives. Fixing Norris’ fuel injection issue solves the isolated problem from Baku, but it won’t touch the wider drag deficit both drivers face against Mercedes on any track built around long straights. We looked at how much this kind of margin matters in our earlier report, and the same trend runs through advanced Formula 1 powertrain technologies shaping this era of the championship. Rather than a single fix, McLaren now needs progress on two fronts at once if it wants to close the gap for good.
