The TrailBlazer is the latest entry into Chevrolet’s SUV line, failing between the much older compact Blazer and the heftier full size Tahoe. As a result, the midsize, TrailBlazer positively boils with technological advances and refinements that Chevy engineers have cooked up for this hot market segment. By building the TrailBlazer on an all new platform, designer were able to tweak the vehicle from the ground up, starting with a hydroformed frame similar manufacture to those introduced in their full size trucks a few years ago. It’s stronger, with enhanced torsional stiffness allowing more precise suspension tuning and on road handling. The suspension is compared of double Arms and coil springs in front, and a 5 link live rear axle. This combination, couple with front and rear roll bars, makes for smooth highway cruising and capable off road navigation. Further spicing the TrailBlazer’s handling is hydraulically actuated rack and pinion steering that delivers a tight 34.4 ft. turning diameter good for parking lot or pine thicket maneuvers. Perhaps the most pleasing feature is found under the TrailBlazer’s hood, the all new 4.2 liter engine.
This is an inline 6 that’s high on output and technology, yet relatively low on fuel consumption given the vehicle’s size. The inherent internal balance of the 6 cylinder configuration males for smooth operation, while dual overhead cams with variable cam phasing provide optimal output and a steady torque curve under varying driving conditions. Peak horse power is surprisingly potent and willing 270 bhp, with torque rated at a nicely toned 275 lb-ft.
