Known for its excellent towing and hauling capacities, the GMC Sierra 1500 is an all-American pickup truck preferred by people who need a vehicle that can handle a lot of lugging. A powerful workhorse, the GMC Sierra is often compared to its sibling, the Chevrolet Silverado. Although both vehicles have nearly the same features all over, the GMC Sierra 1500 has luxury options not present in its Silverado counterpart.
Late 1990s: Light-duty vehicle
The GMC Sierra 1500 was unveiled to the public in 1998 as a 1999 model. Available in three cab lengths (two-door standard, four-door extended, and front-hinged four door), the GMC Sierra 1500 was perfect for light hauling and towing.
Early 2000s: Heavy-duty variant
In 2001, GMC manufactured a top-of-the-line model of the Sierra 1500. Known as the Sierra C3, the new 1500 features an all-wheel drive and a 6.0 L Vortec 6000 engine. By 2002, the name of the vehicle was changed to Sierra Denali. Although the nameplate had changed, the features of the truck remained mostly the same, with the exception of the adjunct four-wheel steering system more popularly known as the Quadrasteer. The addition of the Quadrasteer augmented the truck's lane-changing capacity while towing. However, the idea of incorporating the Quadrasteer in future models was scrapped after GMC accrued poor sales performance of the Denali due to the expensive option.
Another development in the Sierra took place with the introduction of the Vortec High Output (VHO) option. Launched in 2004 but only to a small market in the United States, the VHO package includes a LQ9 6.0 L V-8 engine, which delivers 380 lb·ft (515 N·m) of torque.
Mid-2000s: Hybrid version
The hybrid version of the Sierra came out in 2004. Known as the Parallel Hybrid Truck (PHT), the vehicle featured an engine that automatically shuts down when the brakes are applied. Using a 42-volt electric power, the engine would start again once the brakes are released. The Sierra hybrid was offered for sale in 2005 but only to a few states and Canada. By 2006, the hybrid truck was made available throughout the United States. It was discontinued sometime in 2008.
Late 2000s: Redesigned Sierra
The 2007 model of the Sierra sported revamped features. From the engine to the suspension, down to the minute details of the interior, the Sierra featured a style reminiscent of the Chevrolet Colorado pickups. With better aerodynamics and fuel efficiency rate, the new Sierra is a pleasure to drive.
