Chrysler has been building the Hemi brand for 50 years. A 1966 426 V8 is shown.

From transmissions (Powerglide, Hondamatic) to suspensions (Iso-Strut, Hydra-Coil), automakers have branded and trademarked virtually every consumer-facing vehicle feature. Some branded features come and go with little fanfare (General Motors’ Quadrasteer) while others become part of the automotive lexicon (Ford’s EcoBoost).   

 Few branded icons have reached the level of positive public awareness as Chrysler’s “Hemi” brand. A brand name born of legitimate technology (all Hemi-branded engines do indeed feature at least partially hemispherical combustion chambers), use of the name Hemi began organically enough, with racing success helping to spread the word.

Chrysler resurrected the Hemi name in the early 2000s, this time investing significant marketing money into strengthening the brand. With great presence of mind behind it, the Hemi brand celebrates 50 years of service in the care of several Chrysler nameplates. Included here is the maker’s unedited press release celebrating the anniversary.
