One configuration per trim, named under each heading, with its numbers as Chevrolet prints them. “Up to” is a ceiling printed over several configurations (the notes say whose), “from” the lowest figure, and a range is printed across that configuration’s grades. “Door label” means the maker prints it only on each vehicle’s certification label.
Third-partyA double underline marks a figure from a magazine test, dealer or spec site, not Chevrolet’s own documents: shown only where Chevrolet publishes nothing, and never used for a headline, comparison or ranking. Its page is listed under the plate.
