Nico Hulkenberg said he had little warning prior to a dramatic front wing failure at the Hungarian Grand Prix.
Hulkenberg's front wing collapsed from his Force India on the pit straight, sending the German into the barriers at Turn 1.
Hulkenberg was able to walk away from his damaged car as he retired for the second time in 2015.
"It’s a shame we lost the opportunity to get a great result today," he said.
"I didn’t have much warning that there was a problem with the front wing - there was a harsh vibration just before it broke and after that I was heading straight into the barriers.
"The final impact was not too bad because that part of the track is well protected and it absorbed the energy nicely."
Hulkenberg was nonetheless encouraged by Force India's pace prior to the failure.
"Up until the accident, things were looking very positive: I had made a great start and was racing with the Red Bulls, which shows the step forward we have made with the b-spec car," he said.
"The good news is that we have time over the next week to analyse what happened today and get the solutions in place before the summer break.
"Reliability has been a real strength of ours this season so it’s unusual for us to have these issues and the team will do its homework before we arrive in Spa."
