Autocar is the oldest operating truck manufacturer in the United States, with a heritage stretching back to 1899 and a singular focus on severe-duty commercial trucks purpose-built for the most demanding vocational applications. Unlike general-market truck builders, Autocar designs every truck from the ground up for specific work — including refuse collection, construction, and specialty hauling — with the ACX cab-over, ACMD medium duty, and ACTT terminal tractor among its core models. Autocar's trucks are built at its Indiana manufacturing facility and backed by a lifetime warranty on cab frame welds, reflecting the company's confidence in its craftsmanship and commitment to long-term fleet partnerships.
