Compare the 2500HD Base vs. SLE. What is the difference?
Providing the perfect solution for those who simply enjoy the look of a pickup truck or need the extra space and capacity for intermittent hauling, the 2021 GMC Sierra 2500HD Base model is exception even in its simplistic state. The base model is more impressive than most could imagine, promoting a selection of cab configurations including regular, double, and crew cab layouts. It also offers standard interior tech features, such as a Bed View Camera that offers up a cargo bed video feed for drivers to watch and review. An auto-dimming mirror is also a commendable addition on this model.
Boasting a slightly different interior configuration than other models, the base Sierra 2500HD incorporates a 40/20/40 split bench seat setup with a covered armrest to heighten comfort and convenience. In previous model years, even as early as 2020, this design option was not offered at all.
Another element that is not offered on any other 2021 GMC Sierra 2500HD trim level is the option of E85 FlexFuel to power the standard 6.6-liter V8 engine of the base model. This is an option that is completely new for the 2021 model of the GMC Sierra 2500HD, and consumers are loving it. Enhanced flexibility and modern amenities are part of what draws buyers to the 2021 GMC Sierra 2500HD.
The 2021 GMC Sierra 2500HD SLE incorporates many of the underlying design and mechanical elements that the base model sets forth. Most of its obvious changes revolve around the SLE's manipulation of tailgate features and capabilities. Making the GMC MultiPro tailgate standard, the SLE also incorporates a manual tailgate with a lift option into its exterior design.
Compare the 2500HD SLE vs SLT Trim Levels. What is the difference?
The tailgate options are just a taste of what the 2021 GMC Sierra 2500HD has to offer. Making it easier than ever for buyers to choose what they truly care about in a pickup truck, the Sierra 2500HD has laid out many choices for consumers to consider and select from. This is continued with the number wheel options available for the SLE that range from 18-inch aluminum to 20-inch aluminum with silver accents. The options for the 2500HD transcend into the interior of this very vehicle where SiriusXM, Apple Carplay, Android Auto, and various package options are available.
In fact, the 2021 GMC Sierra 2500HD offers a ProGrade Trailering System and a Preferred Package as options on trim levels as low as the SLE. Making customization available to most buyers, GMC works to provide a variety of selections on all trim levels.
The SLT trim level is where the 2021 GMC Sierra 2500HD really begins to pack on the upgrades and changes both on the inside and outside of this pickup truck. From premium rear floor liners that are removable to multiple USB ports to front bucket seats, there are many things buyers can take advantage of in the SLT trim. Gaining access to a new SLT Premium Package and a Texas Edition SLT Premium Package, the SLT trim level has seen the replacement of pre-existing Plus Packages that were available in the 2020 model year of the 2500HD.
Mechanically speaking, the SLE and SLT models still come standard with the same 6.6-liter V8 as the base model. However, they do not offer the same E85 fueling option that sets the base model apart from others. Paired with a six-speed Allison transmission, both the SLE and SLT trims can produce up to 445 horsepower and put out up to 910 lb.-ft. of raw torque. With an option to upgrade to a 10-speed automatic Allison transmission, fans are content with the towing capacity improvement that the 2021 GMC Sierra 2500HD offers.
Compare the SLT vs AT4. What is the difference?
Taking a sleek but standard look to the next level, the 2021 GMC Sierra 2500HD AT4 amplifies this truck and modifies it with reputable off-road enhancements. Switching out body-color moldings and door handles with black accents and adding harsher elements gives the AT4 model a more rugged appearance that appeals to those who enjoy living life off the beaten path. Offering many of the same wheel options as the Denali model, the AT4 manages to balance utility and luxury well in its innate design.
Featuring an AT4 Premium Plus Package that is all its own, the AT4 also gains access to HD Surround Vision cameras for more comprehensive vehicle position awareness and safety precaution measures. Equipped with cameras that allow for two viewing positions plus a bed view camera always allows drivers to maintain awareness of their pickup truck and potential hazardous nearby.
Overall, the 2021 GMC Sierra 2500HD AT4 adds on to the features that the SLT laid out. It provides an adequate medium between the economical SLT trim and the undeniably luxurious Denali trim level. Balancing between these two trims in an effective manner, the AT4 plays an important role with a fun and adventurous twist.
