Guillaume Moreau has returned home for the first time since his suffering serious back injuries in a crash at the Le Mans Test Day in June.
The OAK driver has been at the Arch rehabilitation centre in Le Mans since the accident, which left him with spinal damage.
An OAK statement said that Moreau has made excellent progress and is now able to walk again. He has also cycled and driven a car.
The Frenchman described his progress so far as "a miracle".
"When I discover that I am not progressing fast enough, and feel that I have reached a plateau, I remember the diagnosis upon arriving at the hospital along with the wheelchair-bound future that had been predicted," said Moreau.
"But two-and-a-half months later I can walk, which is the first miracle."
Moreau still hopes he can return to racing as soon as possible.
"The aim of the surgeon who operated in Angers, Dr Lucas, was to afford me an opportunity to get back in a racing car," he said.
"December offers me a new target, when the first verdict will be given. I know that the road is still long and uncertain but I have the same objective as the surgeon.
"An accident like mine leads to much thought and awareness of, in particular, the question of safety which unfortunately requires accidents of this nature to take place in order for further advances to be made, but the passion is still there.
"I have also remained in very close contact with my team OAK Racing, with whom I have ongoing exchanges."
OAK president Jacques Nicolet expressed his delight at Moreau's recovery so far.
"Since the start his will has not ceased to surprise us all, including the nursing staff that have had to make a special effort to adapt to the extraordinary will of a patient who they have had to force to relax!" Nicolet said.
"He has demonstrated that the competition is not solely confined to the track and that current results suggest every outcome is still possible.
"For Guillaume this is the most important endurance race of his life and I know that whatever happens we will continue to team up with him."
