HRT's 2012 car will only make its debut at the third and final pre-season test as the car has failed two of its mandatory FIA crash tests.
HRT was one of two outfits scheduled to use their new car for the first time at the second test, which takes place at Barcelona later this month.
The team, though, has been forced to push back the launch after the car failed to pass all its FIA crash tests.
According to the team's Twitter page, the new car passed 14 tests but failed two by a "minor margin."
The team added that their 2012 car "should" be in action at the second Barcelona test, which kicks off on March 1st.
The first two tests, though, are not a complete waste for HRT as they have been in action at Jerez using a modified F111 fitted with the latest Pirelli compounds.
