GMT360


GMT 360 is a former midsize truck platform developed and manufactured by General Motors. Sold between the 2002 and 2009 model years, GMT 360 and its variants were the third generation of mid-size SUVs produced by the company. Outside of the United States, it was sold alongside its GMT 330 predecessor until 2005.
The platform would go on to become one of the most rebadged General Motors product lines in modern history; sold by every GM division except Cadillac, eleven versions of the architecture was marketed under six marques. Chevrolet sold two SUVs and a pickup truck; GMC, three SUVs ; Isuzu, two SUVs; following the closure of Oldsmobile, its SUV product line was revived by both Buick and Saab.
Following the cancellation of a planned SUV replacement, the platform was replaced by two CUV platforms. The short-wheelbase GMT360 was replaced by the Theta platform while the long-wheelbase GMT370 was replaced by the Lambda platform. Production ended in late December 2008.
