Mazda and Fiat have announced the signing of the Final Agreement which will see Mazda produce an open-top two-seater sports car for Fiat's Alfa Romeo brand at its Hiroshima, Japan plant starting from 2015.

The new Alfa Romeo roadster will be developed for the global market, and will be based on the architecture of the next generation Mazda MX-5.

The agreement provides for both Mazda and Fiat to develop two differentiated, distinctly styled, iconic and brand-specific roadsters featuring rear-wheel drive.

The Mazda and Alfa Romeo variants will each be powered by specific proprietary engines unique to each brand.

Through this contractual agreement, Mazda aims to enhance development and production efficiency and revitalise enthusiasm for open-top two-seater sports cars around the world.

For Fiat, this collaboration will permit the company to deliver a modern interpretation of the classic Alfa Romeo roadster, utilising the latest technical solutions and helping Alfa Romeo to achieve its stated goals by 2016.
