History and Background

PACCAR traces its origins to 1905, when William Pigott Sr. founded the Seattle Car Manufacturing Company. Its early business focused on equipment for the railroad and logging industries, establishing a manufacturing foundation that later expanded into commercial vehicles.

Over time, the company developed into a major truck manufacturer through its Kenworth, Peterbilt, and DAF brands. These brands serve different markets while sharing the broader resources of PACCAR’s engineering, manufacturing, parts, and customer-support operations.

PACCAR’s role in trucking also extends to powertrain equipment. Its engine, transmission, and axle offerings give customers additional ways to configure trucks for highway, regional, medium-duty, and vocational work.
