This Year's Model Updates:
For 2006, there's a new "VortecMAX" performance group that includes a 345-hp 6.0-liter V8, a heavy-duty tow package and a stronger rear axle; thusly equipped, the half-ton Sierra is on more equal footing with Nissan's Titan and the Hemi-equipped Dodge Ram. The Quadrasteer four-wheel steering option has been dropped, and the optional camper-style mirrors have been replaced by a folding and extending design with a built-in convex spotter glass. Other changes on the GMC truck include slightly updated front-end styling and minor adjustments to trim levels and body configurations.
Pros:
- Roomy extended and crew cab models, variety of V8 engine options, innovative features, slick hybrid-electric option.
Cons:
- Lags behind the competition in refinement, spotty fit and finish, low-grade interior materials.
