For 2006, the Sierra family offers it all. Willing power. Massive torque. Enviable fuel economy. Tremendous towing and hauling capabilities. Spacious, comfortable interiors. Some of the industry's most advanced technology. Outstanding quality. And the industry-leading convenience and safety of available OnStar°. All of which begs the question: Why drive anything less than the legend?
Legendary Quality
Legends aren't made by just receiving awards. But it doesn't hurt either. The fact that GMC Sierra HD models are J.D. Power and Associates Highest Ranked Heavy-Duty Full-Size Pickup in Initial Quality in the U.S.† just helps further demonstrate our point. GMC Sierra is truly one legendary truck.
Feel The Power
Every Sierra pickup has the power you need to get the job done right. Gasoline engine choices start with Vortec 4300 V6 and range all the way up to a 330 hp big-block Vortec 8100 V8. And for those who prefer diesel power, there's a Duramax 6600 V8 that generates 310 hp and a massive 605 lb.-ft. of torque.**
Exclusive Hybrid Technology
Powered by a 295 hp Vortec 5300 V8 linked to a compact 14 kw electric induction motor, the GMC Sierra Hybrid may be the most advanced pickup in the world. GMC's hybrid technology results in a gain of up to 12 percent in fuel economy with no sacrifice in acceleration or drivability.
Precision Hydroformed Components
Sierra's front frame rails are formed via an advanced process known as hydroforming. The result is a very strong front frame section that also provides better front end crush performance, for improved occupant protection in a frontal collision.
Any Trailer. Anywhere. Any Time
GMC's serious truck engineering makes Sierra an outstanding tow vehicle. Fifth-wheel trailer ratings range as high as 7575 kg (16,700 lb.) and the available factory-installed heavy-duty Trailering Special Equipment Package includes a weight-distributing hitch receiver, a trailer brake control wiring harness and more.
Yes, It Really Is A Pickup
Inside Sierra, it's often hard to believe you're in a pickup at all. The ride is impressively smooth and controlled and the space and comfort rival many quality sedans. Dual-zone climate controls, tinted glass and a multi-function Driver Information Centre are all standard equipment.
