New team boss Luis Perez Sala has admitted HRT might struggle to get its 2012 ready for pre-season testing.
With a change of ownership during 2011, the Spanish team has now split with boss Colin Kolles and installed former Minardi driver Sala as principal.
In the background, HRT is also reorganising its scattered headquarters and Sala admitted that it will be a tough winter for the former Hispania team.
"Inevitably we will be delayed by this reorganisation," he told Radio Marca.
"Additionally, the FIA now requires us to pass the crash tests before we can test, which sets the bar even higher.
"I hope it is all done in late January and we make the preseason, but if it gets difficult then at least I hope we make the shakedown before Melbourne," added Sala.
