has just announced that they'll be displaying an updated version of their 4C concept at this year's Frankfurt Auto Show. If you don't recall, the 4C concept was first revealed at Geneva last spring to rave reviews. The updated concept has not been altered styling-wise, but it does now have a new "Fluid Metal" metallic silver paint. The first concept had a matte-red paint job. This two-seater, mid-engined Alfa has been confirmed for production, which is set to begin sometime next year.
