McLaren’s double failure to start at the Chinese Grand Prix left team members and drivers frustrated, and the squad has opened a joint probe with Mercedes High Performance Powertrains. The mclaren f1 china weekend ended with Lando Norris and Oscar Piastri watching from the garage after separate electrical issues on the power unit prevented either car from taking the start.
Mclaren F1 China: What went wrong and the investigation
McLaren qualified fifth and sixth on the grid, but troubles began before the lights went out. Norris remained in the garage with a car that would not start and time ran out for him to join the grid. Piastri’s car was later returned to the garage prior to the formation lap and also failed to make the start.
Team leadership has confirmed a joint investigation with Mercedes HPP to determine why both cars suffered terminal electrical faults on the same power unit family. McLaren described the issues as separate electrical problems, with the team and its engine partner working to understand whether the failures were coincidental or indicative of a deeper systems fault.
Drivers’ explanations and team reaction
Oscar Piastri said the problem that afflicted his car in Shanghai was “an electrical problem on the power unit, different to Lando’s” and called the double non-start “disappointing. ” Piastri noted the setback compounded his recent run of bad luck after missing his home race in Australia the previous week following a crash en route to the grid.
Lando Norris described his issue more briefly: “Not a huge amount, honestly – just an issue that’s not letting us even start the car. ” He said the team were still investigating what was preventing the car from working as it should and called the outcome frustrating after a long effort from the whole team.
Stella, the team boss, said the team found problems “on the electrical side of the power unit” on both cars and called the twin failures an “extremely unfortunate coincidence” of two different electrical issues appearing at the same time. He stressed the priority is to regroup, understand the technical problems and ensure they do not recur as the team prepares for the next race in Japan.
Broader reliability concerns at Shanghai and next steps
The double non-start was part of a wider reliability picture at the event. Four cars in total failed to start, including other power unit and hydraulic-related failures. Aston Martin also suffered early exits, with a battery problem affecting one car and another stopping with “discomfort from vibrations. ” Those incidents underline ongoing reliability and systems-integration challenges for several teams this weekend.
McLaren says it will study the race data and the circumstances around both cars’ faults, then take the findings into work ahead of Japan. Drivers urged the team to “learn what the problem was, and make sure it never happens again, ” while leadership emphasised the need to fix the issues and focus on performance improvements in the coming rounds.
The investigation with Mercedes HPP is now the immediate priority, with the team aiming to identify root causes quickly and prevent a repeat as the season continues.
