Fernando Alonso believes Ferrari have made a step forward in Germany despite missing the weekend's first practice session.
The double World Champion's German Grand Prix weekend got off to a dismal start when his F138 broke down out on track just two laps in.
Ferrari revealed it was an electrical issue that tech director Pat Fry admitted took "a while to work out it was."
Back in action in the afternoon's session, Alonso covered 39 laps with a best time of 131.056, which put him 0.640s short of Sebastian Vettel's P1 time.
"Today went better than last Friday and even if there is still a long way to go, in general we seem to have made a step forward and returned to the level of competitiveness which we had prior to Silverstone.
"One of the positives was the behaviour of the tyres which worked well today and did not create any problems.
"Unfortunately, we lost the morning session because of a programming problem on the electronic control unit, which we then changed.
"That halved our work programme and this evening we will have to do all we can to make up for it, but we already have an idea of where and how to make changes, because Mercedes, Red Bull and Lotus are ahead of us and we want something better than being the third or fourth team in the classification."
