The 600 will be the first Fiat model on a Stellantis platform after the merger of PSA Group and Fiat Chrysler that formed the group in 2021.
The 600 is expected to go on sale by year-end, with a potential unveiling on July 4, according to reports in the Italian news media.
A Stellantis representative declined to comment.
Fiat has used the 600 name for two series of small cars, dating back to the rear-engine replacement for the Topolino in 1955. That version of the 600 was in production until the late 1960s, with variants that included the Multipla ultra-mini van. A second generation was launched in the late 1990s as the Seicento (Italian for 600) minicar and later renamed the 600.
The Fiat 600 will be assembled in Poland at the former FCA Tychy plant, alongside the Jeep Avenger, which was unveiled last October and for which deliveries started in April in Italy.
The e-CMP platform supports gasoline, diesel and full-electric powertrains. The Jeep Avenger is only sold as a battery electric car in most European markets, with a 1.2-liter three-cylinder gasoline engine offered only in Italy, Poland and Spain. The Fiat 600 is expected to follow the same pattern.
A small Alfa Romeo crossover on the same platform will also be unveiled by the end of 2023 and be on sale in 2024. It will also be assembled in Tychy.
The 600 is the first entirely new model unveiled by the Italian brand since the New 500 full-electric small car in 2020. Stellantis said at an analyst conference in February that two Fiat EVs will be launched in the second half of 2023, with a second potentially being a Fiat version of the Citroen Ami quadricycle. Opel already sells a derivative of the quadricycle called the Rocks Electric. The Fiat variant could revive the Topolino name, dealer sources told Automotive News Europe last year.
With few new products in the past decade, Fiat’s European market share has been declining sharply. First-quarter sales were up 7.5 percent to 103,312, according to industry group ACEA. However, the market as a whole grew by 18 percent, and Fiat’s share fell to 3.2 percent from 3.5 percent in the same period in 2022.
