The Fiat Ecobasic is a concept car designed by the Italian manufacturer Fiat and presented in December 1999 at the Bologna Motor Show and exhibited in March 2000 at the Geneva Motor Show.

[2] The purpose of this concept was to prove that it was possible to design and build a car capable of transporting four adults in a structure made of fully recyclable composite materials and whose production and operating costs were ultra-low.

[3][4] The Ecobasic has been homologated according to Euro NCAP standards; moreover, the materials that cover the structure are all recyclable.

[5] The design of the concept has been studied in the wind tunnel, boasting a drag coefficient of just 0.28.

[6] The front grille included a sort of transparent hatch that gave direct access to the coolant and oil reservoirs, as well as the positive and negative battery terminals.
