* Engine: The Z28 had a significantly more powerful engine. The RS typically came with a smaller, less powerful engine (often a V6), while the Z28 boasted a V8. This resulted in a considerable difference in horsepower and acceleration.
* Suspension and Handling: The Z28 had a performance-tuned suspension, designed for better handling and cornering. The RS had a more standard suspension setup, prioritizing comfort over aggressive handling.
* Exterior Styling: While both shared the same basic body style, there were subtle differences. The Z28 had more aggressive styling cues, including typically a different front fascia, ground effects, and often specific wheels. The RS had a more understated appearance.
* Interior: The interiors were largely similar, but the Z28 might have featured sportier seats and other minor differences in trim.
In short, the 1992 Camaro RS was the more affordable, comfort-oriented model, while the Z28 was the performance-focused version with a much more powerful engine and upgraded handling components. The RS was essentially a dressed-up base model compared to the Z28's sporty, performance-bred nature.
