GM GMT Platform - GMT 360

The GMT 360 debuted in 2002 with the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada, as the next generation S/T mid-size SUVs. While it replaced the GMT 330, it shared nothing with the older platform. It used hydroformed frame rails like the larger GMT 800, and was built for GM's Atlas inline engines. The GMT 360 (and the long-wheelbase GMT 370) went on to be one of the most rebadged GM products with six different marques represented.

The 360 uses an independent suspension in front. In the rear, the Ascender and TrailBlazer use a 5-link rear suspension, while the rest have an air suspension. A 4-speed automatic is the only transmission available.

This line is scheduled for replacement during 2009, however, possibly with crossover vehicles based on the Epsilon, Lambda, or Sigma platforms. The GMT 361 replacement program has been cancelled at this point.
