The Group 5 Pantera race cars were converted by private racing teams from Group 4 and Group 3 cars and competed in Group 5 class racing from 1976 to 1981.
The Group 5 cars only had wider body panels and no significant design, mechanical and chassis modifications.

However, two cars were extensively modified to compete in the IMSA GTX and Group 5 class respectively.
The first car having chassis number #001 was constructed from a new chassis by Italian racing team Sala and Marveti.
The second car, having chassis number #1603 was a Group 4 car campaigned by Hugh Kleinpeter in the US and then underwent modification.
Afterwards, the former was converted to Group C class specifications in 1983 and the latter was converted to IMSA GTP class specifications respectively.
Both cars were uncompetitive in their categories.
