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. The 6.0L engine (RPO LS2) was used in the Trailblazer SS model and the Saab 9-7x Aero only, and was rated at 395 hp. All engines were coupled to the 4L60-E/4L70-E 4-speed automatic transmission.

Epsilon is General Motors' mid-size front-wheel drive automobile platform. The architecture was a multi-division project of GM North America, Opel and Saab, and debuted in the 2002 Opel Vectra and 2003 Saab 9-3. Since this platform falls squarely in the center of the worldwide automobile market, GM plans to produce a great many Epsilon vehicles with over a dozen variations. As of 2005, it was GM's highest volume worldwide platform. Even after the dissolution of the GM/Fiat partnership, both companies retain the rights to continue developing Epsilon-derived models.
The Oldsmobile Bravada is a mid-size luxury SUV that was sold by Oldsmobile from 1991 to 2004. The only SUV ever marketed by Oldsmobile, the Bravada was the first light truck offered by General Motors outside of the Chevrolet and GMC divisions since 1924. The flagship of the GM midsize SUV line, the Bravada served as the most luxurious GM SUV prior to the introduction of the GMC Yukon Denali and Cadillac Escalade.
The Chevrolet Tahoe, and its badge engineered GMC Yukon counterpart, are full-size SUVs from General Motors, offered since 1994 and 1991, respectively. Since 1982, Chevrolet and GMC sold two different-sized SUVs under their 'Blazer' and 'Jimmy' nameplates, by introducing the smaller S-10 Blazer and GMC S-15 Jimmy for the 1983 model year, below the full-size Blazer and Jimmy models. This situation lasted into the early 1990s. GMC first rebadged the full-size Jimmy as the 'Yukon' in 1991. Chevrolet however waited until 1994, when they rebadged the redesigned mid-size S-10 Blazer as their 'new Blazer', while renaming the full-size Blazer as the 'Tahoe'. The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States, and was originally used as a trim level on S-10 models. The name Yukon refers to the Yukon territory of northern Canada.
Atlas is a name for a family of modern inline piston engines for trucks from General Motors, used in the GMT355 and GMT360 platforms. The series debuted in 2002 with the Oldsmobile Bravada, and is also used in the Buick Rainier, the Chevrolet TrailBlazer and Colorado, the GMC Envoy and Canyon, the Hummer H3, Isuzu Ascender and i-370, and the Saab 9-7X. The engines use GM's Vortec name, and Straight-4, Straight-5, and Straight-6 engines are all part of the same family, sharing the same manufacturing equipment, rods, pistons, valves, and other parts. They feature coil-on-plug ignition systems, variable valve timing on the exhaust side, electronic throttle control, and a special oil pan with a pass-through for the half shafts in four-wheel drive vehicles. The inclusion of VVT on the exhaust camshaft side allows the Atlas series to meet emissions standards without the use of EGR, simplifying the engine design and increasing power for a broad power curve. The LL8 shares 75% of its components with the LK5 and L52; while the LK5 and L52 share 89% of their components.
The Oldsmobile Custom Cruiser is an automobile that was manufactured and marketed by Oldsmobile from 1971 until 1992.

GMT is a nomenclature used by General Motors to designate multiple vehicle platforms. In use since the early 1980s, the GMT nomenclature is used for light trucks, full-size SUVs, and vans, along with several medium-duty trucks.

The Chevrolet (S-10) Blazer and its badge engineered GMC (S-15) Jimmy counterpart are compact/mid-size SUVs manufactured and marketed by Chevrolet and GMC from the 1983 through 2005 model years, over two generations – until the early 1990s alongside these brands' full-size SUVs with near identical nameplates, but lacking removable hardtops. From the 1992 model year, GMC's big Jimmy had become the 'Yukon', and so the S-15 prefix was dropped on the smaller GMC Jimmy. Starting with the 1995 second generation, the large Blazer was rebranded as the Chevrolet Tahoe, and these mid-size SUVs were simply launched as the 'all-new Chevrolet Blazer'.

As of 2009, the Lambda vehicles have replaced the Buick Rainier, Buick Rendezvous, Buick Terraza, and the GMC Envoy XL and then subsequently the GMC Envoy, Chevrolet TrailBlazer and the Isuzu Ascender. A Denali version of the Acadia debuted for 2011.
