Marussia brought a substantially revised car to the British Grand Prix, featuring a new floor, exhausts, front wing and side pods, but the accident to tester Maria de Villota prior to the Silverstone event, coupled with the bad weather over race weekend meant that the new package could not be evaluated thoroughly.
 
And Glock admitted he is hoping for better weather at Hockenheim in order to get the best out of the new parts.
 
“I hope we just have more stable conditions here to learn more about it,” he said. “It was quite difficult for us to see really what the update gave us – but it definitely felt better in the race [at Silverstone], the pace was quite good, so I’m looking forward to a good weekend here. 
 
“We have some little parts again which should give us a little gain but it’s difficult if everyone else makes at the same time, at the same race, an update, or brings an update, then sometimes it’s a bit difficult to see the step,” he added. “But the car did improve and in the next couple of races we should have a couple more bits and pieces coming.”
 
Glock’s season has been another tough battle at the back of the field with the Marussia team but the German said his motivation never flags despite the lack of results. 
 
“For me it’s quite easy,” he said. “Every day is a new possibility and it’s very easy for me to motivate myself. We are in the greatest championship in motorsport and there is no reason to not be motivated.”
 
Asked if Hockenheim was circuit he has fond memories of, Glock said that his experiences of the track were mixed.
 
“Definitely in 2006 when I won the GP2 race,” he said. “On the last lap I think I overtook the leader and won the race, so I think that was the best one. Not the best memory was 2008 when I finished the race in the wall in the last corner and had to go to hospital, so up and down.”
