Autocar - The World's Finest! In 1950 the Autocar Driver Cab was introduced, which along with the Autocar Sleeper Cab and the Autocar Aluminum Driver Cab, was used on all conventional models produced until Volvo replaced it after purchasing Autocar. In the 1950s Autocar began what it called Custom Engineering, designing each vehicle to the individual customer's specific requirements. At this time Autocar focused on models for construction, logging, mining, quarrying and oil production, as well as lightweight over-the-road designs. Large format photos with informative captions illustrate all of the major models produced during this period. A brief history of the Autocar company is included.
