the mid-1970s onwards, Volvo began building assembly plants with smaller assembly lines, more worker-centric and with better use of automation, leaving Fordism. These were Kalmar (car assembly, built in 1974), Tuve (truck assembly, 1982) and Uddevalla (car assembly, 1989). Kalmar and Uddevalla were closed down in the early 1990s, following yearly losses. The Tuve plant (called the LB plant) replaced the Gothenburg plant (X plant) for truck assembly through the 1980s, as the former could produce more technologically complex models. In 1982, Volvo gained its first plant in the United States, the New River Valley plant in Dublin, Virginia, after acquiring the assets of the White Motor Corporation. Starting in the late 1980s, Volvo expanded its limited bus production capabilities through acquisitions in various countries (Swedish Saffle Karroseri, Dutch Aabenraa, German Drögmöller Karroserien, Canadian Prévost Car, Finnish Carrus, American Nova Bus, Mexican Mexicana de Autobuses). In the late 1990s, after a short-lived joint venture with Polish manufacturer Jelcz, Volvo built its main bus production hub for Europe in Wroclaw. In the 1990s, Volvo also increased its construction equipment assets by acquiring the Swedish company Åkerman and the construction equipment division of Samsung Heavy Industries. In 1998, the company opened an assembly facility for its three main heavy product lines (trucks, construction equipment, and buses) near Bangalore, India. Volvo sold all its car manufacturing assets in 1999. Following the acquisition of Renault Véhicules Industriels and Nissan Diesel in the 2000s, Volvo gained various production facilities in Europe, North America, and Asia. In 2014, Volvo's Volvo Construction Equipment acquired the haul truck manufacturing division of Terex Corporation, which included five truck models and a manufacturing facility in Motherwell, Scotland.
