No, while Abarth might use mostly Fiat cars as a base, the cars leaving Abarth's factory are almost entirely new. Stellantis Italy owns both Fiat and Abarth, but Abarth is entirely operated on its own, and that is why not all Fiat models received Abarth versions. Everything on the Abarth models is changed except the body of the vehicle, but even the suspension and engines are reworked to cater to the race and sports car market.
