Technical glitch costs Lando Norris top speed in Azerbaijan GP Qualifying

Lando Norris faced a frustrating qualifying session at the Azerbaijan Grand Prix, as a technical glitch compromised his top speed and left the McLaren driver fifth on the grid. Despite a strong run of form against his teammate, Norris found himself significantly off the pace during Q3, finishing three tenths behind Oscar Piastri—his largest deficit of the current season.

A Specific Power Deficit

“There's more in my car for some reason than the other car,” Norris explained immediately following the session. “So we have to understand why I'm basically having to push more than Oscar to try and make up for my straightline speed.”

Data confirmed the struggle, showing Norris was 3.4km/h slower than Piastri in terms of top speed. McLaren team principal Andrea Stella has already identified a potential culprit: a localized issue with the fuel injection system.

“On Lando's side specifically, we observe a deficit of power that we are investigating,” Stella commented. “It seems to be linked to some behaviour of the fuel injection... It looks that occasionally the power unit generates a bit less power, but this is a specific phenomenon.”

The Battle Against Mercedes Efficiency

Beyond the immediate technical glitch, McLaren is grappling with a broader performance gap regarding straight-line efficiency compared to Mercedes. In Baku, the disparity was stark: George Russell outpaced Piastri by 8.1km/h and was a massive 11.5km/h faster than Norris.

When questioned if the issue stemmed from the power unit or aerodynamic drag, Norris suggested it was a combination of both. He emphasized the need for McLaren to make significant strides to remain competitive on high-speed circuits.

Stella maintained that while both teams use the same Mercedes power unit, the Mercedes package appears more effective overall. “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,” Stella explained. The team views this deficit not as a power unit failure, but as an engineering opportunity to optimize their chassis and aerodynamic profile.
