Overview
Major platform shift — Mazda ended the Ford partnership and now shares with Isuzu. Underneath is the D-Max RG with the 4JJ3-TCX 3.0L diesel. Mazda interior styling and trim sit on top. Buyers get the toughness of the Isuzu mechanicals with a nicer cabin than the D-Max. Mazda dealer network is thinner than Isuzu Ute Australia's regional reach, especially in remote areas.
