Abarth will focus on its existing range instead of developing new models based on more recently launched Fiats
Abarth chief Marco Magnanini has told Autocar there will be no bespoke model for the marque in the medium term.
2010's Abarth 'Speedster' sketch had been said to preview roadster and coupé derivatives of the Fiat 500.
Abarth is also unlikely to add more power or supplement its 1.4 turbos with larger Fiat Group powertrains like Alfa Romeo's 1750 TBi: "We like to have the perfect ratio between power and weight," said Magnanini.
The Abarth 500 and Punto ranges currently peak at 178bhp.
