| Successor | GM Theta platform (GMT360) GM Lambda platform (GMT370) |
GMT 360 is a vehicleplatform that was manufactured byGeneral Motors from the 2002 through 2009 model years. Underpinning the third generation of GM mid-size SUVs, the GMT360 architecture replaced the pickup truck-derived GMT330 chassis introduced for 1983. Vehicles using the platform were produced as five-door SUVs, a retractable-roof wagon/SUV/truck, and a midsize hardtop convertible pickup truck.
The GMT360 architecture is among the most widely rebranded GM platforms in modern history. Alongside its adoption by each GM brand (exceptCadillac,Hummer,Pontiac andSaturn), the SUV platform was additionally marketed by associated brandIsuzu. Following the closure ofOldsmobile after the 2004 model year, its version was adopted by theBuick andSaab brands.
Retired after the 2009 model year, the platform was originally slated to be replaced by a successor body-on-frame SUV (codenamed GMT361), with GM instead replacing the GMT360 vehicles with theTheta platform and the long-wheelbase GMT370 replaced by the three-rowLambda platform (which also replaced all GM minivans). The last GMT360 vehicles were assembled on December 23, 2008.
The first GM SUV platform not derived from pickup trucks, GMT360 retainedbody-on-frame construction, introducing fully boxed hydroformed frame rails. The wheelbase is 113 inches (6 inches longer than the GMT330), with a 129-inch long-wheelbase variant (designated GMT370). Rear-wheel drive was standard, with part-time four-wheel drive and all-wheel drive as options.
The platform useddouble wishbone independent suspension in front with a5-link solid rear axle; auto-leveling air suspension was offered as an option for some versions.
GMT360 vehicles debuted the 4.2LAtlas inline-6 (replacing the 4.3L V6). For 2003, a 5.3L V8 engine was introduced as an option for non-Oldsmobile vehicles, with a 6.0L V8 becoming an option in 2006. The 395hp engine was exclusive to the Chevrolet TrailBlazer SS and the Saab 9-7X Aero. All three engines were coupled to the4L60-E/4L70-E 4-speedautomatic transmission.
An example of early car recycling processes was seen with the use ofThermoplastic olefin (TPO) that had been recycled from bumpers to create the air intake cowling in these vehicles.[2]
