The Mack Magnum was a heavy-duty truck that was produced and manufactured from 1999 to 2003{{cite web |url=http://www.lesrenaultdepapier.fr/ae_magnum.htm |title=AE - Magnum |language=fr |website=lesrenaultdepapier.fr |access-date=1 September 2016}}{{cite web |url=http://www.trucksplanet.com/catalog/model.php?id=517 |title=Mack Magnum |website=trucksplanet.com |access-date=1 September 2016}} by Mack Trucks Australia, a division of AB Volvo. It consisted of a Renault Magnum cab and chassis, with an all American Drive line including a Roadranger 18-speed transmission and had either Rockwell or Dana drive axles. Although a 454 hp Mack engine was an option. This truck was not "replaced" by the Mack Quantum, as both were sold alongside each other, the former being a premium heavy-duty truck, the latter the smaller lighter less expensive model. Its popularity waned quickly in Australia due to electrical problems and parts availability issues and it was removed from Mack Australia's lineup after only five years.
