Robert Kubica will join up with the Manor LMP1 team for a three-day test at Aragon with a view to racing for them in the World Endurance Championship.
The Pole, who will be Williams' reserve driver for the 2018 season, has declared an interest in the endurance series and will get behind the wheel of the Mecachrome-powered Ginetta LMP1 on Monday.
Manor are stepping up into LMP1 category for the 'Super Season' which begins at Spa in May and concludes at next year's Le Mans. As it stands, there are no conflicts with the Formula 1 calendar after WEC opted to move Fuji away from the United States Grand Prix weekend.
The British team are set to field two cars in the LMP1 class which, Fernando Alonso's Toyota aside, is largely made up of privateers such as Rebellion Racing, SMP, Dragonspeed and ByKolles.
If all goes well in the test, Kubica could well be getting his teeth stuck into a full competitive campaign alongside his commitments with Williams.
