Double DNS for World Champions as Mercedes Power Unit Faults
Team principal Andrea Stella confirmed that McLaren's two cars failed to leave the garage in front of a packed crowd due to separate electrical issues affecting their shared power units. Drivers Lando Norris and Oscar Piastri were unable to start after engineers discovered distinct faults on identical components within both Mercedes engines, marking an unprecedented double withdrawal for World Champions this season.
Key Points
-
1McLaren failed to make the Chinese Grand Prix with both cars due to separate electrical power unit issues discovered before their scheduled starts.
-
2Team Principal Andrea Stella confirmed that McLaren attempted repairs but determined there was no chance of starting after finding faults on identical components in each car's Mercedes engine.
-
3The double 'Did Not Start' (DNS) marks a historic moment for the team, representing its first occurrence since two decades ago and leaving title hopes significantly impacted by reliability failures ahead of schedule.
Developments
McLaren plans to investigate engine supplier Mercedes regarding simultaneous power-unit failures that prevented Oscar Piastri from starting two consecutive races, a situation team principal Andrea Stella described as exceptional and uncharacteristic for their partnership. These electrical issues have left McLaren behind both rivals in the 2026 regulations era while engineers struggle with root causes believed linked to shared components within Mercedes' High Performance Powertrains system.
McLaren failed to complete a single lap of the 2026 Chinese Grand Prix due to two separate, unfixable electrical faults in their drivers' units that occurred after qualifying. Consequently, both Lando Norris and Oscar Piastri received Did Not Start (DNS) results as mechanics could not resolve the issues before race time expired.
McLaren's double world champion title has been severely damaged by reliability issues at the Shanghai race where both cars retired before qualifying due to power unit electronic problems and an earlier crash for Oscar Piastri. Consequently, Lando Norris dropped 36 points in driver standings while McLaren lost a significant gap of over eight units behind Mercedes on manufacturer results with no immediate fix available from their mechanics team.
