The 2026 GMC Sierra 1500 is GMC’s full-size, light-duty pickup, and the lineup starts at $38,300 for the work-ready Pro and tops out at $84,400 for the Denali Ultimate, before destination, taxes, and dealer fees. Eight trims (Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate) pair with four engines: the standard 2.7L TurboMax, the 5.3L V8, the 6.2L V8, and the 3.0L Duramax Turbo-Diesel. Crew Cab is offered across the range, with Double Cab on Pro, SLE, and Elevation and a Regular Cab reserved for the Pro. Properly equipped with the Duramax, it tows up to 13,300 lbs, enough for a loaded gooseneck on a Lakeway job site or a boat headed out to Lake Travis for the weekend. Browse the current Sierra 1500 inventory to see what is on the lot now.
For 2026 the AT4 now comes standard with the Duramax diesel rather than the 5.3L V8, a change worth noting if you cross-shopped the prior model year. Super Cruise hands-free driver assistance is standard on the Denali Ultimate and available on the Denali, while GMC rates the TurboMax’s 430 lb-ft as best-in-class standard torque and lists best-in-class standard front head- and legroom for the Crew Cab. Shoppers weighing the electric truck can also read the Sierra EV vs Rivian R1T comparison, or look at the off-road Sierra AT4 in stock. Use the guides above to compare trims, dig into specs and towing, plan maintenance, or weigh the Sierra against the F-150 and Silverado.
