Volvo Trucks (Swedish: Volvo Lastvagnar) is a truck manufacturing division of Volvo based in Gothenburg, Sweden.

Volvo Trucks was a separate company within Volvo. The Volvo Group was reorganised on 1 January 2012 and as a part of the process, Volvo Trucks ceased to be a separate company and was instead incorporated into Volvo Group Trucks along Volvo's other truck operations, as Renault Trucks and Mack Trucks.^[1]

The first Volvo truck rolled off the production lines in 1928, and in 2016 Volvo Trucks employed more than 52,000 people around the world. With global headquarters in Gothenburg, Sweden, Volvo manufactures and assembles its trucks in eight wholly owned assembly plants and nine factories owned by local interests.^[2] Volvo Trucks produces and sells over 190,000 units annually.

Mack Trucks, Inc., is an American truck manufacturing company and a former manufacturer of buses and trolley buses. Founded in 1900 as the Mack Brothers Company, it manufactured its first truck in 1905 and adopted its present name in 1922.^[1] Mack Trucks is a subsidiary of AB Volvo, which purchased Mack along with its then parent company Renault Véhicules Industriels in 2000.^[2]

Founded originally in Brooklyn, in 1900, the company moved its headquarters to Allentown, Pennsylvania five years later, in 1905. The company remained in Allentown from 1905 until 2009. In 2009, the company relocated its headquarters to Greensboro, North Carolina.^[3] Mack products are produced in Lower Macungie, Pennsylvania,^[4] and Salem, Virginia,^[5] with all powertrain products produced in its Hagerstown, Maryland plant. Mack also maintains additional assembly plants in Pennsylvania, Australia, and Venezuela. The company also once maintained plants in Winnsboro, South Carolina, Hayward, California and Oakville, Ontario, though these plants have been closed.
