The ZL1 name — dormant since the 69-unit 1969 COPO — returned as a supercharged 6.2 L (580 hp) regular production model. Reportedly it was going to be badged Z/28 until GM felt a blown grand-tourer didn't fit that name. Simultaneously Chevrolet revived COPO as an annual factory-built, race-only drag special — 69 cars for 2012, a deliberate callback to the 1969 count. 2012 also brought a 45th Anniversary edition.
For this model year, CamaroFacts separates documented changes from production totals that remain secondary or unresolved. The engine, identification, and confidence notes below are intended to make those boundaries visible instead of smoothing them into a single unsupported narrative.
