The company name may allude to the production of expensive-looking but low-quality vehicles, as the element zirconium is used to make cheap diamond substitutes. The Zirconium Building in Liberty City is modeled after the Chrysler Building, although Chrysler's analogue in the HD Universe appears to be Schyster.

- In GTA IV's audio files, this manufacturer is misspelled as "Zireonium" and is mispronounced by the police as "Zireoenium". Interestingly enough, a sound clip with the same mispronounciation can be found in GTA V's files that was probably recorded before being corrected.
- Zirconium is a frequently used material for making cheap diamonds. This is maybe a reference to the Stratum's low impact resistance and low build quality.
