History of the GMC Sierra
The history of GMC pickup trucks is truly extensive, going back to 1918, but the Sierra nameplate was only a trim level until 1988. The GMC Sierra with its current name didn't arrive until 1999. As part of the naming change, the Sierra 1500 was redesigned and got a new set of engines. The base engine was a 4.8-liter V8 with 255 horsepower, while the top option was a 6.0-liter V8 with 345 horses on the Sierra Denali. This first light-duty Sierra still had minimal production.
In 2003, Quadrasteer became an option on the GMC Sierra, giving the model a class-leading turning radius. It didn't last long, however, ending for the 2006 model year because it was too expensive. If you look at the lineup from that same model year, it is incredibly similar to the current arrangement. There was the choice of a Regular, Extended, or Crew Cab in the Work Truck, SLE, SLT, and Denali trims. The unique feature was that an SLE Hybrid was also offered, although this was eventually dropped due to lack of interest. When the next generation arrived as a 2007 Sierra, the SL and SLE trims offered multiple tiers like they do today. In 2009, a 403-horsepower, 417-pound-foot 6.2-liter V8 engine arrived as did a 6-speed automatic, which would become standard the following year. The current generation arrived in 2014 with higher-quality upholstery, an available 8-inch touchscreen, and a new front grille.
