Robert Kubica will drive at next month's in-season test

British driver Oliver Rowland wll drive the Williams car on day 1 whilst Kubica will take to the cockpit for the second day. The test will take place in Hungary, in the week after the Hungarian Grand Prix. 

"It's another step in the right direction of achiveing my goal of being in F1," Rowland said. 

"Everything went very well at the last test in Barcelona and it's nice to know they're giving me another chance and have trust in me. I'm aware that you don't get many opportunites to show your talent in F1."

Kubica, Williams test and reserve driver, also drove in the Barcelona tests. He featured in FP1 in Spain and will take part in an aditional two practice sessions this season. 

Both drivers have been rumoured to take over Brendon Hartley at Toro Rosso. Seeing as this test takes place at the end of July/start of August, it probably removes both Kubica and Rowland from this list.
