GMC shares its bones with Chevrolet but dresses everything a step nicer, and the Denali trims are a luxury brand of their own: Denali accounts for a huge share of GMC sales for a reason. Trucks and SUVs only, from the Terrain to the 1,000 hp Hummer EV.
Redesigned with a bolder face and a 15-inch touchscreen, the Terrain is the Equinox's dressier twin, and for 2026 it finally gets AT4 and Denali versions.
Grown into a full three-row family hauler: 328 hp turbo, a 15-inch portrait screen, and real AT4 hardware for dirt-road weekends.
The Tahoe's upscale twin, also available stretched as Yukon XL: V8 or Duramax diesel, up to 8,400 lbs of towing, and a Denali Ultimate that flirts with Escalade territory for less.
The Colorado's premium twin: every Canyon gets the 310 hp turbo, and the AT4X AEV is a factory-built rock crawler with 35s.
The Silverado's better-dressed twin with two aces: the carbon-fiber-reinforced CarbonPro bed and the MultiPro six-way tailgate. Denali and AT4X versions out-luxury and out-crawl most of the field.
Sierra 2500HD and 3500HD: gas V8 or 470 hp Duramax diesel with Allison transmission, up to 36,000 lbs of towing, and Denali luxury on top of a work-grade frame.
Up to about 478 miles of range and a MultiPro Midgate that opens the bed into the cab. For 2026 the lineup grows to three trims, and battery coverage runs 8 years / 100,000 miles.
Pickup or SUV, up to 1,000 hp, CrabWalk diagonal driving, and air suspension that lifts about six inches in Extract Mode. Nothing else on the road behaves like it. Battery coverage is 8 years / 100,000 miles.
GMC's all-new 2027 half-ton, revealed alongside the next Silverado: new Gen 6 V8 engines, a redesigned interior, and six trims from Pro to Denali Ultimate.
Future model details come from manufacturer announcements and press reports; timing, specs, and availability can change.
Mechanically they are twins: same engines, transmissions, and frames. The Sierra costs a bit more and gives you GMC-only hardware like the MultiPro six-way tailgate and available CarbonPro bed, plus the Denali and Denali Ultimate luxury trims and the AT4X off-road flagship. If you want a work truck value, Silverado; if you want the nicer cabin, Sierra.
Denali is GMC's luxury sub-brand: signature grille, premium leather, real wood, and top audio and tech. Denali Ultimate stacks exclusive materials and Super Cruise on top. Roughly one in three GMCs sold is a Denali, and resale on them holds up well.
AT4 is the off-road trim: factory lift, all-terrain tires, skid plates, 4WD. AT4X is the flagship: Multimatic DSSV spool-valve dampers, front and rear locking differentials, and a full-luxury interior. AT4X AEV editions add extreme armor and 35-inch tires on Canyon.
The Sierra EV tops out around 478 miles of range in Max Range form, among the longest of any EV sold. The Hummer EV runs up to roughly 380 miles depending on body and trim. Both carry 8 year / 100,000 mile battery coverage and can power tools or even a house with the right equipment.
The Terrain, typically starting around $30K. On Broker Black every Terrain listing shows your real monthly payment with your local Arizona or Nevada taxes and fees included.
