What heraldic family emblem inspired the crest used by Cadillac?

Cadillac’s crest was inspired by the Cadillac family coat of arms.

The automobile company took its name from Antoine de la Mothe, sieur de Cadillac, the French explorer who founded Detroit in 1701. His claimed heraldic arms supplied the visual basis for Cadillac’s emblem, although the automotive version has been repeatedly redesigned.

Cadillac badges have changed substantially over time. Earlier versions included a detailed shield, a crown, and decorative elements; later designs simplified the shield for clearer use on grilles, wheels, and advertising. The emblem is therefore not a direct display of modern Detroit’s municipal arms.

A common mix-up is confusing Cadillac’s crest with the winged designs used by several other luxury marques. Cadillac’s emblem is fundamentally a heraldic shield, while its name refers to a historical French nobleman associated with Detroit’s founding.
