Nico Hulkenberg says missing out on Friday afternoon practice cost him the chance to challenge in the top ten qualifying shootout which has made his task trickier in tomorrow's Hungarian Grand Prix.

The Force India driver's team-mate Sergio Perez suffered rear suspension failure during the opening free practice at the Hungaroring, sending the Mexican into a dramatic roll which he walked away from unhurt.

With the driver safety paramount Force India pulled out of running in the afternoon session to discover and analyse the full extent of the fault with its new B-spec VJM08. Hulkenberg felt losing that key practice time has limited his setup progress and hampered his qualifying charge as he had to settle for 11th.

"The main penalty of yesterday was losing the track time and maybe with more set-up time we would have been able to make it through to Q3 today," Hulkenberg said. "It's been quite a difficult weekend for the team, but I have to give credit to the way they have handled the situation and fixed it."

The German driver also had to pull out of his first qualifying run in Q2 after Fernando Alonso's McLaren stopped on track and caused a brief halt to proceedings.

"The red flag caught me out because I was on my first quick lap and had to abort it," he said. "So I only had one lap to get the job done and I just missed out by two hundredths of a second."

Perez echoed his team-mate's comments after only managing 13th in qualifying and says his team have been unable to keep up the rate of improvements on the new car because of his incident in FP1.

"I was very optimistic on Friday, before the accident, but what happened has affected us quite a lot," Perez said. "We have lost some of the new upgrades that we had brought to the race - parts that were working really well and were making a big difference."
