Dani Clos will be back in action for HRT at the German GP, replacing Narain Karthikeyan in Friday's first practice.
The 23-year-old Spaniard was last in action at the British GP, contesting first practice. However, heavy rainfall meant he completed just 11 laps.
But despite his limited running at Silverstone, the Spaniard is confident he still learnt valuable lessons that he will carry through to Hockenheim.
"I'm happy to be getting into the car again just a few weeks later; it's another very good opportunity for me," said the HRT test driver.
"I wasn't able to do much mileage in Silverstone because of the weather but my sensations and the work we did were very positive both for me and the team.
"We did a great job on a wet track and, although it was brief, it was very intense.
"Hockenheim will be a good opportunity to improve and do more miles with the F112. Besides, it's a track I know and that I find enjoyable, and a place where I have good memories.
"I'm confident and really looking forward to getting back on to the track."
