Endurance isn't clearly defined now, there's the possibility to do 24 mins races for 24H, or more laps. By default GT and endurance can't drive together but you can create custom lobbies with your own rules. Also in training mode all cars are allowed.
hi alexander, when wil be able the endurance cars ?
Could you tell us how the endurance mode will work? Will we be able to use GT cars and prototypes at the same time?
