Lotus pair Kimi Raikkonen and Romain Grosjean admitted they did not learn much on a Friday that saw plenty of rain hit the Hockenheim circuit.
The Enstone based team brought some very noticeable upgrades to this weekend's German Grand Prix as they tested a Mercedes-like double DRS system on their chassis'.
The new system on first viewing appears to intake air around the roll-over bar behind the driver's head, rather than ducting air from the front wing to stall the rear like that of Mercedes. A new central pylon in the middle of the rear wing was also visible throughout free practice.
Raikkonen, despite the upgrades, felt the session was unfulfilled.
“We didn't learn a lot today with the weather conditions as they were,” he said. “It was like Silverstone when we also didn't have very good conditions.
“We tried a few different things which I think some people noticed today. It would have been nice to have some more dry track time but you can't do anything about that. The track does feel quite slippery when it's wet; it's definitely not very grippy in these conditions. Overall, it was a pretty normal Friday when you try different things and get as much running as the weather allows.”
Grosjean in the sister car was tenth and fifth fastest in the respective sessions and thinks the lack of knowledge in regard to tyres may help him come Sunday.
“It was a difficult session with the rain coming down,” he said. “We had a few things we were hoping to test in dry conditions but unfortunately this was not the case.
“If we get to Sunday without any dry laps then people won't have so much of an idea about tyre degradation and the difference between the compounds, which may help me starting further back on the grid with the penalty. Either way, we now have a good base line setup from today and hopefully this will help bring us a decent result at the end of the weekend.”
