  1. 1 With the Max 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.

02 / What changed

New for 2018

The 2018 Suburban against the 2017, the previous model year we hold. Only what Chevrolet’s documents show: nothing here is inferred.

  • No retail configuration added or dropped: the 6 sold in the 2017 are all here.
  • Same range as the 2017: towing, curb weight and length.

03 / Sources

The 2018 documents

4 documents behind the 2018 Suburban’s figures. The maker’s own come first; a third-party page fills in only a number the maker doesn’t publish, and wears its own mark.
