The Renault Magnum main tractor was produced from 1990 to 2013.
The model’s release time coincided with the acquisition by Renault Industrial Vehicles of the American company Mack Truck in 1990.
Thus, V 8 Mack EE9 engines with a volume of 16.4 liters and a power of 520-560 hp were installed on some models. Renault motors had more modest characteristics, but for their time 380-420hp. it was quite decent performance for the inline six with a volume of 12 liters.
In 2001, Renault Industrial Vehicles itself became part of Volvo and became part of a group called Renault Trucks.
Since then, there has been a consistent unification of components and assemblies brought by the company to common standards.
In 2005, Renault Magnum trucks began to be equipped with new power units with a working volume of 12.0 and 13.0 liters, which received the designation DXi 12 and DXi 13.
