Weâve just taken in a 2020 GMC Sierra 1500 AT4 Crew Cab Pickup. Itâs finished in Dark Sky Metallic with a Jet Black leather interior accented by Kalahari trim ruggedly bold yet upscale and refined. With 103,817 miles, just one previous owner, and a Good condition rating, this Sierra AT4 offers the rare combination of diesel efficiency, off-road hardware, and premium interior comforts.
At its core is GMCâs Duramax 3.0L turbo-diesel I6 paired with a 10-speed automatic transmission. Delivering 277 horsepower and a massive 460 lb-ft of torque, this setup gives you effortless towing, calm highway cruising, and fuel efficiency of up to 26 MPG highway and 22 MPG city. The AT4âs 4WD system includes off-road suspension, skid plates, hill descent control, and all-terrain tires, making it equally at home on muddy trails or snowy commutes.
Add the integrated trailer brake controller, Hitch Guidance with Hitch View, and the in-vehicle Trailering App, and this truck becomes a confident towing partner. Black running boards and a soft tonneau cover add convenience and protected cargo space.
Step inside, and the AT4 greets you with heated and ventilated front bucket seats, heated rear outboard seats, and a heated steering wheel comfort that takes the sting out of icy mornings and hot afternoons alike. The driver enjoys memory seat settings, a 10-way power seat, and a clear view of key vehicle stats via the color Driver Information Center. The leather-wrapped steering wheel, Jet Black and Kalahari accents, and thoughtful storage in the center console add both sophistication and practicality.
Technology is where the Sierra shines. GMCâs Premium Infotainment System with 8-inch touchscreen delivers wireless Apple CarPlay and Android Auto, Bluetooth, HD Radio, SiriusXM with 360L, voice commands, and available 4G LTE Wi-Fi. Wireless charging keeps your phone topped up, while USB-A and USB-C ports front and rear keep passengers connected. With premium audio, navigation features, and trailer-specific tools, every drive feels both smart and capable.
Utility meets innovation in the truck bed. The spray-on bedliner shrugs off heavy use, LED cargo box lighting keeps gear visible at night, and the MultiPro tailgateâs six functions transform into a step, a workbench, or a load stop as needed. CornerStep rear bumpers, a 120-volt bed-mounted outlet, wheelhouse liners, and integrated tie-downs all make this Sierra ready for real work and real play. Up front, LED reflector headlamps, signature daytime running lights, and body-color bumpers complete its athletic stance.
