Between 1991 and 1992, the Italian coachbuilder Zagato offered a conversion package for the Ferrari 348 tb, the "Zagato Elaborazione". The changes were purely cosmetic; engine and mechanicals remained as on the donor car. At the front, the dummy central grille was removed, the side air intakes became larger and lost their strakes, and a glass engine cover revealed the V8. Added to this were round triple taillights, an electronically controlled rear spoiler, Zagato's signature roof with two bulges ("double bubble"), custom wheels from OZ Racing and a redesigned interior with suede. 22 cars were announced, but only 10 were built.
