20th July 2014 (F1Plus / Rosie Baillie) - The Force India duo bemoaned the drop in temperature on race day for their lack of pace.
Temperatures on Saturday reached 55C (131F) while temperatures on race day dropped to 35C (95F).
Hulkenberg, who finished seventh, said the lower temperature meant the front tyres were degrading fastest rather than the rear tyres.
“It was a difficult race and different to what we expected, mainly due to the lower temperatures with the track being 20 degrees cooler than on Friday,” said Hulkenberg.
“We were expecting a lot of rear degradation, but after a couple of laps it became clear the fronts were the limiting tyres, and that changed the game.”
The German driver also suffered engine issues mid-race which he and the team managed to overcome.
“I also had to overcome some engine issues in the middle of the race because there were some hesitations and it was not driving smoothly,” he said.
“It was a good recovery by the team to solve the issue. It was important to score more points and from that point of view I’m feeling satisfied.”
Perez said the lower temperatures made the car harder to drive. The Mexican crossed the line 10th after pitting for new tyres three times.
“It was a very strange race; the track changed a lot compared to Friday and it was the front tyres that were suffering from degradation and not the rears,” Perez said.
“Together with the much lower temperatures, it made the car very difficult to drive.”
Deputy team principal Bob Fernley echoed their comments but was happy with their finishing positions and points faul.
“We were expecting to be stronger in the race today, but the drop in temperatures didn’t help us and both drivers struggled to show the pace we had seen during our long runs on Friday,” said Fernley.
“Considering the challenges we faced today, we can’t be disappointed to come away with seven points.
“It keeps us in fifth place in the standings and demonstrates once again that we can score good points even on days when both drivers are struggling with the balance.”
