Chronology | |
Predecessor | GM GMT330 platform |
Successor | GM Theta platform (GMT360) GM Lambda platform (GMT370) |
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 (one, with a retractable roof); 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 (codenamed GMT 361), 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 (also replacing the GM U platform minivans). Production ended in late December 2008.
Chassis overview
The first GM SUV platform not derived from pickup trucks, GMT360 retained body-on-frame construction with fully boxed hydroformed frame rails, A 113-inch wheelbase was used, with GMT 370 released as a long-wheelbase variant (using a 129-inch wheelbase). Rear-wheel drive was standard, with part-time four-wheel drive and all-wheel drive as options.
The platform used double wishbone independent suspension in front, with a 5-link solid rear axle; auto-leveling air suspension was offered as an option for some versions.
Originally developed for the Atlas series of inline engines, in 2003, a 5.3L V8 was introduced as an option, with a 6.0L V8 becoming an option in 2006. All engines were coupled to the 4L60-E/4L65-E 4-speed automatic transmission.
