About the Sierra

The GMC Sierra --- also known in other GM circles as the Chevrolet Silverado --- is a long-standing truck range that has been part of the GMC truck range since 1998, and is still going strong. GMC Sierra models have spanned 4 generations, the first starting in the 1999 model year, the second arriving in 2007, the third in 2014, and the current fourth-generation in 2019.

The latest versions of the GMC Sierra retain a budget-friendly starting price of just $31,200 for the Sierra 1500 Limited, and $35,400 for the Sierra 1500. There is also the GMC Sierra HD model, which starts at $40,200.

Towing capacity is a big selling point when it comes to any pickup truck, and GMC likes to promote their capacities prominently. Both the Sierra 1500 and Limited can tow up 13,000-lbs, but the HD (Heavy Duty) model blows both out of the water with its colossal capacity of 36,000-lbs.

Besides a huge range of trim levels for each one --- 8 trims on the Sierra 1500, for example --- GMC are also competitive with the likes of Ford when it comes to engine options. To use the Sierra 1500 as an example once again, drivers can choose between 4 different engines and 2 different transmission options.

Standard powertrain is a 2.7-liter 4-cylinder unit delivering up to 310-hp and 420 lb-ft of torque. V8 engines include a 5.3L (355-hp), and a 6.2-liter (420-hp). They even offer a diesel option that delivers up to 460 lb-ft of torque. The base-level engine pairs with an 8-speed automatic, while the others pair with a 10-speed automatic.

One criticism of the Sierra is that off-road capabilities rarely come as standard as they do with models such as the Ford F-150. Drivers have to specifically buy the AT4 trim (from $65,150) to access off-road features like the 2-inch suspension lift on the Sierra 1500. The stark price difference makes it a tough call for some.
