Autocar sold 3300 units, though the number fell to 1000 in 1932 and continued to decline during the Great Depression. Larger trucks with "Blue Streak" gasoline engines and Diesel engines, mainly from Cummins, came later. During World War II, Autocar supplied 50,000 units to the military, including specialty vehicles such as half-tracks; during its entire prewar history, the company had only built 70,000 units. Autocar ranked 85th among United States corporations in the value of World War II military production contracts. Civilian production resumed in 1944 and sales increased greatly after the war. Autocar soon had 100 dealers. Subsidiary of White Motor Company The boom after the war ended quickly, however; and in 1953, Autocar sold out to the White Motor Company, which made Autocar their top-of-the-line brand among their "Big Four" brand portfolio. The Ardmore plant was replaced in 1954 with a new plant in Exton, Pennsylvania, though the Ardmore plant burned while being torn down in 1956 and the fire could have destroyed a neighborhood. Autocar's "Custom Engineering" process for meeting each customer's needs led to a reputation as "World's Finest". White replaced Blue Streak engines with its own Mustang, and production of gasoline-powered trucks ended in 1965. AP off-road vehicles became an important product for Autocar. The 1964 AP19 shown in September 2007 at a Golden Age Truck Museum exhibit "has a GCW of 900,000 lbs, a 30,000lb front axle, planetary rear axles rated at 200,000 lbs, and was originally powered with a 525 HP Cummins V-12 diesel which was later replaced with a 6-cylinder Cummins KT rated at 750 HP." Most Autocar trucks continued to use the Autocar Driver Cab; in 1977 Autocar launched the Construcktor 2 model which used the Xpeditor cab that had recently been launched by sister-company, White. The Exton plant ended production in 1980, with production moving to the modern White plant in Ogden, Utah. White, Volvo and GMC Shortly after the move to Utah in 1980, with White insolvent, in 1981 AB Volvo acquired the U.S. assets and brands to become Volvo-White LLC. Volvo produced trucks under both the White and Autocar brands and Autocar continued as the division focused on severe-duty trucks. The Autocar DK severe-duty line was launched in 1983 and, as a replacement of the venerable DC line, was widely used in heavy dump truck, concrete mixer, refuse, and oil field applications, among many others.
