Robert Kubica, who test-tested on Tuesday with Williams at the Hungaroring track, turned out to be spinning during the test drive.
Kubica, who used F1 car for the first time after six years with Renault, began negotiating with Renaut, the final choice of French manufacturer Sainz.

No information was given about the work done on the second test day on Tuesday, but it was announced that the test was efficient.
