Red Bull team principal Christian Horner has confirmed Max Verstappen suffered a driveshaft issue during qualifying for the Saudi Arabian Grand Prix.
The two-time champion was hot favourite for pole position after dominating the three practice sessions at the Jeddah Corniche Circuit but will start 15th after a mechanical issue forced Verstappen out of Q2.
Verstappen had claimed he was suffering with an engine issue having lost acceleration as he headed towards turn 13, but onboard audio suggested otherwise.
