Robert Kubica was perhaps expected to start the Russian Grand Prix low down the field, but taking a new power unit has confirmed he will remain at the back of the grid.
Williams have taken a new Internal Combustion Engine (ICE), turbocharger and MGU-H in Sochi - the fourth Kubica has used all season for each element.
It means he will serve enough penalties to send him to the back of the grid regardless of qualifying performance.
