The GMC Sierra 1500 SLT is for someone who wants a truck to do truck things but also wouldn't mind being pretty comfortable while doing them. The SLT gives you that nice middle ground, serious capability, an upscale cabin, and enough technology to make you wonder how we ever survived when trucks just had a bench seat, an AM/FM radio, and a heater with three settings.
This 2026 GMC Sierra 1500 SLT is finished in Volcanic Red Tintcoat and powered by the 3.0-liter Duramax turbo-diesel inline-six, paired with a 10-speed automatic transmission and 4WD. The Duramax is the real story here, delivering the low-end torque you want from a truck while still returning an impressive 22 MPG city and 26 MPG highway. That's the kind of fuel economy that can make your buddy with the big gas V8 suddenly stop asking what mileage you're getting.
Duramax diesel. 4WD. SLT. Volcanic Red. A grown-up truck that can work hard, clean up nicely, and doesn't treat every gas station it passes like an old friend.
