Vanthoor was revealed at the Goodwood Festival of Speed last month as one of the 10 drivers who will race for the factory Porsche Penske Motorsport team next year across the World Endurance Championship and IMSA SportsCar Championship.
The Belgian will join fellow GT works drivers Kevin Estre, Michael Christensen, Matt Campbell and Matthieu Jaminet, plus Porsche Formula E ace Andre Lotterer and previously-announced pair Felipe Nasr and Dane Cameron. Two more drivers are yet to be announced.
