Victor Guerin will drive the #24 Ocean Racing Technology car in the fourth round of the GP2 Series this weekend in Barcelona, while Josef Kral returns to the driving seat at Barwa Addax.
Brazilian driver Guerin is the third driver to have raced the Ocean car so far this season. Jon Lancaster drove the car the season opener in Sepang but budget delays meant that Brendon Hartley took over for the double header in Bahrain.
It will be the third single-seater series Guerin will have raced in in as many weekends, the 19-year-old having also raced in Formula Two at Portimao and Auto GP at the Hungaroring. Contesting the full Auto GP campaign with Super Nova, he lies eighth in the standings and finished second in the first race in Hungary.
Meanwhile, with Dani Clos taking up free practice 1 duties with HRT this weekend, Czech driver Josef Kral returns behind the wheel of the #2 Addax car. He raced in Malaysia with the team but was subsequently left on the sidelines for the Bahrain rounds in favour of Clos.
