Williams lacked the pace to challenge their rivals at Hockenheim after Pastor Maldonado
and Bruno Senna both finished outside of the points.
Maldonado started fifth on the grid but a bad second stint left the Venezuelan scrambling amongst the midfield to finish 15th.
“It was a difficult race today,” Maldonado complained. “We started okay but the car lacked pace in the second stint and I didn't have the grip needed to maintain my position due to some damage caused in the early part of the race.
“The car improved a bit in the final stint on the soft tyres but we need to go away now and understand why we were not as quick as we were earlier in the week in time for the next race in Hungary.”
Bruno Senna also dropped back from his grid position to finish 17th. The Brazilian was forced to pit on the first lap after making contact with other cars off the start in an incident he feels ruined his race.
“I had a stronger pace in the race than the result suggests so it's disappointing to finish where we did,” Senna said. “It was unfortunate because I lost almost a minute on the first lap after I had to pit after making contact which put me right at the back, and from there it's always difficult to make your way through the pack.
“Nevertheless we do have good pace in the car and if I can qualify higher up the grid next time then we stand a good chance of getting points in Hungary.”by Dan Connor
