The Lyriq order guide has been published, and every RPO code is coded as “Standard” equipment, including Super Cruise. Interestingly, all the usual Emissions RPO codes are listed (Federal, New England, California) even though the car has zero emissions! Initially, there are only two colors available, Silver and Black, with Black being “late availability.” It’s already well-reported that the initial build run will be RWD only.
I’m sure updates and revisions will soon follow.
