I’ve been going through the RPO codes for my Pontiac G6 as listed on the label in the glove box. These are supposed to be the options that were installed at the factory. I ran across a couple that don’t seem to make much sense.
NU6 Emissions system, California PZEV-Maybe the thing was rated for California.
R6F Chevrolet, 10 gallon tank, natural gas vehicle.-I’m quite sure there is not a separate
natural gas tank on the car anywhere.
HP0 Hybrid propulsion not installed-Makes sense because it doesn’t have it.
Just thought it was kind of interesting but never thought an item could be listed on the RPO label and not actually be installed.
