Sebastian Vettel's calamitous Aston Martin debut concluded with him being punished by the stewards for a second time in as many days at the Bahrain Grand Prix.
After the quadruple world champion was thrown to the back of the grid – penalised for failing to slow under yellow flags in qualifying – he then crashed into Alpine's Esteban Ocon during the race.
Vettel was hit with a 10-second penalty for the incident and two points on his licence, taking his tally for the weekend to five. He will be banned for one race if he accrues seven more over the next 12 months.
The 33-year-old signed for the rebranded Aston Martin team in the hope of renewed glory following a dismal end to his six-season spell with Ferrari.
But he has appeared uncomfortable in his new machine. Even before his grid penalty, he was due to line up for Sunday's race only 18th of the 20 runners.
Vettel took the chequered flag last but one, with just the son of his boyhood hero Michael Schumacher, debutant Mick, behind him on track.
Explaining his crash with Ocon, a deflated Vettel said: "I was sure he was leaving me space on the left, but then he crossed back and as soon as I was behind him I locked up and couldn't avoid hitting him.
Aston Martin have struggled to adapt to mandatory rule changes to the to the floors of the cars, which impacts downforce.
Team principal Otmar Szafnauer said: "It was important to mark Aston Martin's return to Formula One with a finish inside the points and Lance drove an intelligent race.
"But it is clear the new regulations have impacted more negatively on teams such as ourselves. Sebastian's race was always going to be tricky with him having to recover from the back of the grid."
