Last year's Spanish Grand Prix victor will start tomorrow’s race from seventeenth on the grid after failing to progress to Q2 for the third time this season.
Maldonado qualified in eighteenth but moves up one place following a penalty to Esteban Gutierrez.
"We’re having a difficult time with the car at the moment, but we have been working very hard to improve things. We were missing a lot of grip which made it difficult to get a good time today," he said. "In terms of performance, we’re not there but we will keep focusing on the work needed to move us up the grid."
Team-mate Valtteri Bottas will start the race from sixteenth place.
"Unfortunately the result from today shows where we are compared to others, but I still think we’ve made a step forward and we’re heading in the right direction," said the Finn. "It seems everyone else has improved as well which means we are in similar position to the first four races. Hopefully we can keep making the same steps race-by-race. We will try our best tomorrow and I still think we can climb up the grid as our race pace looks good."
