2006 Full size SUV : Chevrolet Trailblazer EXT

Chevrolet’s midsize Trailblazer sport utility vehicle (SUV) debuted early in 2002 as a five-passenger vehicle. It was soon joined by an extended-length Trailblazer EXT with a seven-passenger capacity. Since 2005, a revised V-8 has operated with Displacement on Demand technology, which promises up to 5 percent greater fuel economy. Under certain light-load driving conditions, the number of active engine cylinders decreases from eight to four. Both models offer an optional 5.3-liter V-8, an upgrade from the standard 4.2-liter inline-six-cylinder engine.

General Motors’ Stabili-Trak electronic stability system is standard on 2006 models. LT editions get a revised exterior appearance. The standard six-cylinder engine gains 16 horsepower. Side curtain-type airbags are optional in 2006 models, and an occupant-sensing system for the front passenger seat is also available. Trailblazer EXT SUVs come in LS and LT trim levels. A new high-performance SS model is offered only in the regular Trailblazer’s lineup. Seating for five people is standard in the regular Trailblazer, but the seven-passenger Trailblazer EXT gets a third row with a full foot well and 23.4 cubic feet of space behind the seat. GM’s On Star communication system is standard.

Options include a backseat entertainment system with a DVD player, XM Satellite Radio, power-adjustable pedals, rain-sensing wipers and leather seating surfaces. All-disc antilock brakes are standard. Side curtain-type airbags are optional. Dual-stage front airbags deploy with varying force depending on crash severity. Ride comfort and performance are EXT SUVs strong points, and the standard inline-six-cylinder engine does a credible job. Despite its truck origin, the expertly cushioned suspension planes the sharp points off nearly any reasonable road surfaces.
