Meaning and history

ACDelco Logo history


ACDelco’s journey began in 1916, named United Motors Corporation by William C. Durant, GM’s founder. Initially, ACDelco unified independent auto parts makers.

In 1918, GM bought United Motors, marking its first major acquisition.

The brand evolved, becoming AC Spark Plug Division in 1927, reflecting its specialization in spark plugs.

The ’70s saw the merger of AC Spark Plug with United Delco, creating the AC-Delco division. This merger expanded its product range beyond spark plugs to a vast array of automotive parts.

In 1995, GM streamlined the brand to “ACDelco”. This rebranding aimed to solidify its market presence globally. Over the years, ACDelco embraced innovation, expanding into electronics and other advanced automotive technologies.

ACDelco stands as a global leader in the auto parts industry, committed to innovation and excellence.
