the base for Bertone's Camargue coupť.

For those who thought the pure, unadorned lines of
Opron's design were too plain, a variety of accessories were available.
The engine also powered the MEPX Formule Bleue racing cars which
were created by Maurice Emile Pezous, CitroŽn concessionaire at Albi to
allow youngsters to acquire racing skills. Originally powered by
an Ami 8 engine in the MEPX1, this was judged to be insufficiently
powerful and was replaced by the GS engine in the MEPX27 in 1971.
As previously mentioned, in 1977, the GS was given a
gentle facelift - new rear lights, new grille and new dashboard.
