* Heritage Edition is a trim package, not a separate model: The RS is a trim level (relatively basic). The Heritage Edition was an *optional package* you could add *onto* an RS (or other trim levels, like the IROC-Z). It wasn't a separate model line.
* Visual Differences: The main differences lie in the appearance:
* Paint: The Heritage Edition offered specific paint schemes, usually featuring a two-tone paint job that harkened back to earlier Camaros (often a combination of black and red or white and red). The RS had a wider range of available single-tone colors.
* Graphics: The Heritage Edition featured special graphics packages, typically including racing stripes and/or "Heritage Edition" badging. The RS had no such special graphics.
* Wheels: The Heritage Edition sometimes (but not always) came with unique wheels. The RS used more standard wheel designs.
* Interior: While there were slight variations, interior differences between a base RS and a Heritage Edition were usually minimal. Sometimes they might have specific interior trim or badging.
* Mechanical Differences: There were *no* significant mechanical differences between an RS and an RS with the Heritage Edition package. The engine, transmission, suspension, etc., were all the same. The Heritage Edition was purely an aesthetic upgrade.
In short: Think of the 1992 Camaro RS as the base model, and the Heritage Edition as a cosmetic upgrade package available for that model. You could have a 1992 Camaro RS *without* the Heritage Edition features. But you couldn't have a 1992 Camaro Heritage Edition without it essentially being an RS with that package.
