The French manufacturers Renault and Heuliez Bus developed the "Mégabus" (officially the Heuliez GX237), a bi-articulated high-floor bus, in the late 1980s.
It was also rumoured that ROCAR (Autobuzul) made a double articulated DAC bus, but nothing is confirmed, as there are no official photos or prospects (while even for prototypes, ROCAR Autobuzul was issuing prospects and flyers), therefore the existence of a double articulated DAC Bus is uncertain.
