Advanced Flying Automobile Company (AFACO) was a small U.S. venture based in Huntington Beach, California that pursued a roadable aircraft in the late 1990s and 2000s. The firm promoted the Sokol A400, a “flying car” concept attributed to aerospace engineer Branko Sarh. The A400 was described as a four-seat automobile that deployed telescoping wings for flight while retaining conventional road use, positioning the project among contemporary dual-mode experiments rather than a production automobile. No evidence emerged of series manufacturing, certification, or sales. AFACO therefore remained a concept-stage marque whose significance lay in its contribution to the period’s revival of interest in roadable aircraft rather than in commercial output.
