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.
After the 2009 model year, General Motors ended medium-duty truck production.
However, all of the GM minivans (save for the China-exclusive Buick GL8) were dropped, ergo the name went unused.
For its production from 2006 to 2011, the compact wagon-bodied Chevrolet HHR rode on the Delta platform.
In 2004, with the release of the first-generation Chevrolet Equinox, the GMT 191 name was internally used to refer to it.
Consequently, the GMT190 name was retroactively applied to the second-generation Chevrolet Tracker, which could be considered one of the Equinox's predecessors.
For 2007, the release of the new Saturn Outlook and GMC Acadia, as well as the Lambda platform, occurred.
Lambda itself was called the GMT960 series, with each individual vehicle it underpinned getting an alternate GMT-designation as well.
