On 24 July 2017, it was announced that Kubica would participate in the test for Renault, which would be held after the conclusion of the Hungarian Grand Prix. Abiteboul, Renault's team managing director, said the test will allow the team to fully assess Kubica's current capabilities, and how likely he might be to "return to competition in the upcoming years". Kubica completed 142 laps of the Hungaroring on his return, finishing fourth-fastest nearly 1.5 seconds behind Sebastian Vettel.
