Marchionne said that by moving the Mazda Miata-based sports car from the Alfa Romeo brand to the Fiat brand, the car was delayed only by three or four months. That suggests the sole changes were to badging (it may be called a "Fiat Abarth," with, I think "Fiat" still the car's brand name) and to the grille, which must have lost the signature Alfa nose.
