History
The 2300 project traces its roots to Italy as project 102/12. A prototype was assembled in 1971 and sent to Brazil for tests in 1972. It was engineered entirely in Italy for the Brazilian market, and it was launched in March 1974 under the slogan “The imported manufactured in Brazil”.
The engine choice was made because of import difficulties in the 1970s. The factory used the four-cylinder engine of the Alfa Romeo 1900, enlarged to 2,310 cc. The car was based technically on the older 1900, and its exterior was similar to the Alfetta, although it was 41 cm longer.
