More problems for Red Bull Powertrains: Tsunoda will not start in GP

Over the on-board radio, Tsunoda shouts at one point, "Engine lost." Then the Japanese driver is told to turn off the engine and climb out of the car.

It means big problems again for Red Bull Powertrains. Last week Max Verstappen, Sergio Perez and Pierre Gasly retired and number four is already a fact. Tsunoda, Perez and Gasly have also had to change several engine parts this week.

"I don't know what happened, but looks like something in the drivetrain. We had to stop the car he can't race," team boss Franz Tost said.
