 and the profits from this permitted him to regain control of GM in 1916. At approximately the same time, he assembled United Motors.

Durant's founding of United Motors has parallels in his earlier experience in the horse-drawn carriage industry in Michigan. In the late 19th century he was co-owner of the Durant-Dort Carriage Company, one of the nation's leading carriage manufacturers. Concerned that they could not source components and raw materials at affordable prices or in sufficient quantities, Durant-Dort created a vertically-integrated operation owning hardwood forests and manufacturing its own bodies, wheels, axles, upholstery, springs, varnish and whips.

AC-Delco

In 1974, in an effort to streamline its operations and marketing, General Motors merged the AC Spark Plug with United Delco, which for years had been selling to the same customers, to create the new AC-Delco.

By the mid 1990's there were further changes to the division. In 1994, Delco-Remy, part of the division since 1916, was spun off to private investors and is now known as Remy International, Inc.  Also in 1994, GM created Automotive Components Group to run Delco Electronics. ACG was later renamed Delphi and spun off from GM in 1999. 1995 saw a rebranding of AC-Delco. The hyphen was dropped and ACDelco received a new logo and marketing initiative.
