Editing General Motors GMT platform (section)

== Primary applications ==
Primary applications of the platform – those that are equivalent in basic RWD/frame structure to each other – existed from 1981 to 1989, and again since 2018.

=== Light trucks and SUVs ===
Pickups and SUVs have been the main vehicles underpinned by GMT platforms, being involved for the entirety of the platform's existence.

=== Hummer ===
In contrast to the Hummer H1–designed and assembled by AM General, the [[Hummer H2]] and [[Hummer H3]] were developed by GM, receiving their own platform designations. Designated the '''GMT825''', the H2 was derived from the GMT820 (Chevrolet Tahoe/GMC Yukon), with its own midsection frame design and a rear frame shared with the 2500-series GMT800 pickup trucks.<ref>{{cite web|last=Clavey |first=William |title=The Hummer H2 Is A Grand And Opulent Bad Idea |url= http://jalopnik.com/the-hummer-h2-is-a-grand-and-opulent-bad-idea-1796613645 |website=Jalopnik |date=12 July 2017 |access-date=25 September 2017}}</ref>

The H3 SUV was designated the '''GMT345''', a close variant of the GMT355 (Chevrolet Colorado/GMC Canyon). The 2009-2010 H3T pickup truck was designated as the '''GMT745''', adopting a nomenclature closer in line with the GMT700 used by the later second-generation Colorado/Canyon.

=== Vans ===
The 1996 [[Chevrolet Express|Chevrolet Express/GMC Savana]] replaced the previous G-series Van/Vandura, adopting the '''GMT600''' designation. As part of a model update and revision for 2003, GM changed the Express/Savana to '''GMT610''', which remains in use. The model line competes with the [[Ford Transit]], and [[Ford E-Series]] (dependent on configuration), [[Mercedes-Benz Sprinter|Mercedes-Benz/Freightliner Sprinter]], [[Dodge Ram Wagon]], and the [[Ram ProMaster]] (cargo van only).

=== Medium trucks ===
For 1990, the [[Chevrolet Kodiak|Chevrolet Kodiak/GMC TopKick]] medium-duty trucks adopted the '''GMT530''' designation (sharing the cab of the GMT400 trucks). For 2003, the line was redesigned, becoming the '''GMT560''' platform (sharing a version of the GMT610 cab). After the 2009 model year, General Motors ended medium-duty truck production.

Since 2018, a medium-duty version of the GMTK2XX has been produced in a joint venture with Navistar International.
