The Spanish Formula One team HRT, who this month signed Indian Narain Karthikeyan as one of their drivers, won't be able to try out their new car until next month's final pre-season test after it failed two crash tests.
The team, which has been using its old car a a two-day testing session, says it hasn't passed mandatory tests.
HRT says the failure means they won't be able to roll out the new car at the second pre-season test in Barcelona later this month.
Under new regulations introduced this season, cars must have passed the FIA crash tests and have had their chassis approved before they can take part in regular testing.
