Gearbox problem for Kubica

Due to mixed weather conditions, it was a difficult test day. Because the track was wet at the beginning, Robert waited for the conditions to improve, but lost time later due to a gearbox problem. This happened when other drivers set their quick lap times in the dry. In the afternoon, Robert worked on a rain set-up, testing extreme weather tyres and wet weather tyres. At the end of the session, he practiced starts in the wet.
