About GMC Sierra

The 2020 Sierra is part of a generation that started with the 2019 model year. Changes for 2020 are mild, coming only one year after a redesign. Towing capacity has decreased marginally from the previous year’s total but remains above 12,000 pounds. A few additional amenities are also available, such as adaptive cruise control, a bed-view camera, and an audio system incorporated into the MultiPro tailgate.

The Sierra had several significant improvements as part of the 2019 facelift. The selection was expanded with two additional trims (Elevation and AT4), as well as two new engine options: a turbocharged four-cylinder and a turbodiesel. A surround-view camera system, pedestrian recognition, and a head-up display are among the new available driver assistance technologies for the 2019 model.

You can possibly save hundreds of dollars by purchasing a used Sierra, but you will miss out on the benefits of the redesign if you purchase a model prior to 2019. If you’re looking for a used GMC, read our reviews of the 2018 GMC Sierra and 2019 GMC Sierra. You should also look through our Used Car Deals page to learn about the many savings and discounts available on used vehicles.

The Sierra has a starting price of around $30,000. That is a normal entry level pricing for the class. Things can quickly get more pricey if you choose a higher trim level or a more powerful engine. Ones with diesel engines begin at $45,000, while models with the biggest V8 begin around $51,000. The Sierra Denali trim level is the most expensive, starting at $54,700.

The Sierra rides comfortably, but the Ram 1500 is likely to have the most comfortable ride in the class. The Ram can tow and haul more than the Sierra, and its base engine is more fuel-efficient. The Ram offers one of the most upmarket cabins in the class, outperforming the GMC, with two rows of roomy seats and an easy-to-use infotainment system. Basically, anything the Sierra can do, the Ram 1500 can do better or at least as well.
