Truck Month is moving fast at Honor GMC, and while our entire front line is built for utility, this week we are turning our attention to the absolute peak of the lineup. For drivers who want massive commercial-grade capability wrapped in world-class luxury or trail-ready engineering, our selection of premium trims has never been stronger.
Right now on the National City Mile of Cars, we are featuring a deep lineup of AT4, AT4X, Denali, and Denali Ultimate models across our Canyon, Sierra 1500, and Sierra HD families. These aren’t just trim levels—they represent the absolute highest tier of GMC performance, technology, and interior refinement.
Here is what defines the premium collection waiting on our lot this week:
The Rugged Elite: AT4 & AT4X
Built for the driver who refuses to let the pavement dictate their weekend plans, but still demands a premium cabin experience.
- GMC Canyon AT4: Combining an ultra-wide stance and a factory 2-inch lift with a premium interior, it’s the ultimate agile trail companion. Powered by the high-output TurboMax™ engine putting down 430 lb-ft of torque, it rules the desert backroads.
- Sierra 1500 & HD AT4: Featuring a rugged 2-inch factory suspension lift, standard 4WD with an autolocking rear differential, and specialized Rancho® monotube shocks. Inside, you are greeted by an exclusive Jet Black interior with Kalahari accents and heated/ventilated perforated leather seating surfaces.
The Luxury Benchmark: Denali & Denali Ultimate
For those who view their truck as a mobile command center and demand the finest craftsmanship available on the road today.
- Sierra 1500 Denali Ultimate: The undisputed king of the light-duty segment. It features an exclusive Alpine Umber interior with full-grain leather seating, authentic open-pore Paldao wood trim, and 16-way power-adjustable massaging front seats. Tech highlights include a massive standard 13.4-inch diagonal infotainment screen and available Super Cruise™ hands-free driver assistance technology.
- Sierra 2500HD & 3500HD Denali Ultimate: When heavy-duty trailering meets ultimate luxury. Driven by the monumental Duramax 6.6L Turbo-Diesel V8, these trucks feature a striking Vader Chrome grille on the outside and standard premium tech like the ProGrade™ Trailering System with up to 14 available camera views to make hauling absolute luxury.
