Robert Kubica will get behind the wheel of the Mecachrome-powered Ginetta G60-LT-P1 for a second time as he continues to assess whether to sign up for the World Endurance Championship.
Kubica was only able to manage two laps in the Manor LMP1 car in the first test at Aragon due to engine trouble, but the Pole will be returning to the track on March 9 to have another opportunity to drive the car.
The Williams reserve driver is still yet to make a decision on whether he will follow in Fernando Alonso's footsteps and compete in the WEC 'Super Season' alongside his Formula 1 commitments.
"Honestly I didn't have time to think about it," Kubica said at the Circuit de Catalunya, home of F1's winter testing. "I'm quite busy here and it's quite a lot of work I'm doing.
"So I will have to review, the schedule is very busy so if I have to add some racing into it will mean from the middle of February until after Le Mans [in June] I will have less than 10 days at home.
"I have to make sure I can do things properly in here [with Williams] and in racing. I don't want to do many things and it will become a bit messy."
