Vehicle description

This 2021 GMC Sierra 1500 AT4 4WD Crew Cab combines rugged capability with refined comfort, highlighted by a striking gray exterior and a jet black interior accented with Kalahari trim. Powered by a Duramax 3.0L I-6 diesel engine delivering 277 horsepower, this truck offers efficient performance with advanced direct injection, variable valve control, and an intercooled turbocharger. Designed for both work and leisure, the AT4 trim includes a 2-speed transfer case and an integrated trailer brake controller complemented by an in-vehicle trailering app, enhancing towing confidence and convenience. Inside, driver and front passenger seats are ventilated and heated, wrapped in perforated leather-appointed trim for added comfort on any journey. Keyless open and start, along with a remote vehicle starter system, provide ease of access and operation. Technology is well represented with a touchscreen primary display offering wireless audio streaming, internet radio capability, voice-activated controls, and external memory support through the premium GMC Infotainment System, paired with 4G LTE Wi-Fi hotspot capability to keep you connected. Safety features include a rear vision camera, StabiliTrak electronic stability control with proactive roll avoidance, brake assist, an immobilizer, and a Teen Driver mode with restricted driving alerts, supporting a confident and secure driving experience.

AutosXchange Intel uses current dealer-advertised asking prices, not completed sales or appraisals. It compares the same trim and condition (new or used) where at least three are listed nationwide, and adjusts the expected price for mileage; it is not adjusted for options, condition or accident history. Similar listings are searched within 50, 100 and 250 miles of the dealer first, then the dealer's state, then nationwide. The left gauge spans ±25% of the expected price.
