Sergio Perez expressed his frustration after failing to complete a single racing lap at the Malaysian Grand Prix.
Perez was set to start the race from 14th place but a technical problem left the Mexican stranded in the garage, unable to start the race.
"I’m disappointed not to have a chance to race today," he said.
"We are still investigating the cause of the problem but the car kept going into neutral when I was downshifting on the way to the grid. I made it back to the garage but we could not find a solution.
"I need to focus on the positives because we learned a lot from the weekend so I hope we can come back stronger in Bahrain. It’s been a frustrating weekend for me but at least we are racing again in seven days and can look forward to putting the disappointment behind us."
