De Villota was hospitalized for more than two weeks and had two operations after suffering severe head and facial injuries when she crashed into a team truck during a test at an airfield in England on July 3.
Marussia said Saturday that the 32-year-old De Villota returned home Friday.
The Russian-owned team said she had made “significant progress” over the past two weeks and was well enough to go home. The team thanked the English hospital staff for the “remarkable care and attention” De Villota received.
Marussia race drivers Timo Glock and Charles Pic also wished De Villota well in her recovery.
