Both McLarens out of Chinese GP before the start

Formula One world champion Lando Norris and McLaren teammate Oscar Piastri failed to start the Chinese Grand Prix on Sunday due to car problems.

Champions McLaren discovered an electronics issue with Norris’s car before it was due to head out on track while Australian Piastri’s car was then pushed off the grid and back to the garage.

Mechanics removed the floor on Norris’s car, with the team still working to resolve the problem as the grid closed for the second race of the season.
