2026 GMC SIERRA 1500 DENALI ULTIMATE 4WD 6.2L V8 MASSAGE SEATS SUNROOF 22s KICKER MULTIPRO ONYX BLACK LANCASTER PA
This 2026 GMC Sierra 1500 Denali Ultimate 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission. Finished in Onyx Black with the exclusive Alpine Umber full-grain leather interior, this is GMC's flagship Sierra with massage seats, sunroof, Adaptive Ride Control, 22-inch wheels, and an extensive trailering and camera system.
The 6.2L V8 produces 420 horsepower and 460 lb-ft of torque, giving the Denali Ultimate the strong naturally aspirated power that fits a premium full-size truck perfectly. It's smooth around town, strong on the highway, and has plenty of power when towing or passing.
The Denali Ultimate is the top of the Sierra lineup, and the interior is where you really see the difference. The Alpine Umber full-grain leather interior is unique to the Ultimate and gives the cabin a much more upscale look and feel. You get heated and ventilated front seats with massage, heated second-row seats, heated steering wheel, wireless charging, power-adjustable steering column, and a power sunroof.
Ride quality is another major advantage. Denali Premium Suspension with Adaptive Ride Control continuously adjusts the damping to help keep the Sierra controlled and comfortable over changing road surfaces. It gives this truck a noticeably more refined feel without taking away its capability.
Technology includes a huge 15-inch multicolor Head-Up Display, HD Surround Vision, Bed View Camera, Navigation, and front and rear parking sensors. The 12-speaker Bose Premium Series audio system provides the upgraded sound system you'd expect in an Ultimate.
It's also loaded for towing with the Trailering Package, integrated trailer brake controller, Hitch Guidance with Hitch View, in-vehicle Trailering App, Trailer Camera Provisions, Trailer Side Blind Zone Alert, and trailer tire-pressure monitoring capability. An automatic-locking rear differential adds traction when conditions get slippery.
Out back you get a GMC spray-on bedliner, LED cargo lighting, 120-volt bed outlet, and MultiPro tailgate. This one also has the Kicker MultiPro Tailgate Audio System, adding built-in outdoor audio for tailgating, camping, or jobsite use.
The 22-inch ultra-bright machined wheels, body-color wheel arches, signature Denali grille, and Onyx Black paint give this Ultimate the clean upscale appearance these trucks are known for.
Mileage is another advantagethis Sierra is sitting 4,274 miles below the market average.
If you want the luxury end of the half-ton truck market without giving up V8 power or real truck capability, this one has the right combination: 6.2L V8, Denali Ultimate, massage seats, Adaptive Ride Control, sunroof, 22s, premium Bose audio, and a loaded trailering setup.
