The Maranello-based team had originally intended to run last year's SF21 car for the four days of the test, which is scheduled as a warm-up exercise for race drivers Charles Leclerc and Carlos Sainz, plus tester Robert Shwartzman.
However, shortly before the testing programme began, Ferrari had to revise its plans because of confusion over whether or not it was actually allowed to run one of last year's cars.
