Polyphony boss Kazunori Yamauchi has confirmed that Gran Turismo 5 will get a mid-race save feature.
"I’m sorry. Game saves during endurances. They are currently under development," he said in response to a fan when asked about said feature.
No timeline's been given for the release of the feature, though.
Gran Turismo 5 only got a massive update a couple of weeks ago which added online B-Spec mode.
