2020 GMC Yukon

One configuration per trim, named under each heading, with its numbers as GMC 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.

  1. 1 With the Heavy-Duty Trailering Package (NHT): the maker’s figure for the configuration with that factory option.

A dash means the maker’s documents we have don’t give that number for that configuration, and a column with no number for any configuration of the year isn’t shown. “Door label” means the maker prints it only on each vehicle’s certification label, and “not published” that the maker doesn’t print it, or points elsewhere. “Up to” is a ceiling the maker prints over several configurations; a range is the maker’s own, printed across the grades of that configuration.

Third-partyA double underline marks a figure from a magazine test, dealer or spec site, not the maker’s own documents: shown only where the maker publishes nothing, and never used for a headline, comparison or ranking. Its page is listed with the year’s sources.

The documents

Every number on this page comes from one of these 8 documents. Last checked .

The maker’s own documents first: press kits, spec sheets, towing guides and owner’s manuals. A third-party page (a magazine test, dealer or spec site) fills in only a number the maker doesn’t publish, never a rating, and the figure wears its own mark. How we source the numbers.
