For example, in the 1980s you could order a Z28 Camaro with a 2.5 liter engine, although this was rare. However most RPO codes that are promoted to model names are appearance packages only, and are not related to speed or engine performance.

This happened again with the Corvette Z06 models. The Camaro Z28 name came from an option code which specified a performance-oriented configuration. While fairly complete it does not contain every RPO that is on the vehicle.Ī few RPO codes have become notable enough that they have been used as model names. In 2018, the RPO Sticker was replaced by a QR code located on the B pillar (driver's side, between front and rear doors). For RPOs that never became notable the code may be reused for entirely dissimilar options. In some cases (such as this), the RPO specifies a package with similar function (in this case performance) to previous uses of the code. For example, the ZR1 performance option was available for the Corvette for the 1970, 1990 through 1995, 2009, and 2019 model years.
