Motorious readers are getting an exclusive boost in their chances to take home one of GMC’s most capable heavy-duty trucks. For a limited four-month window, participants can enter to win a brand-new 2026 GMC Sierra 2500 Denali Ultimate — and Motorious readers receive additional entries, increasing their odds in this high-impact giveaway.
At the heart of the Sierra 2500 Denali Ultimate is the 6.6-liter Duramax turbo-diesel V8, paired with a 10-speed automatic transmission. The combination is engineered to deliver substantial torque, confident towing capability, and smooth, controlled performance whether hauling equipment, towing a trailer, or cruising the highway.

The Denali Ultimate trim represents the top tier of GMC’s heavy-duty lineup, blending work-ready engineering with elevated comfort and technology. This example is finished in Onyx Black and features an Alpine Umber interior, creating a striking contrast between bold exterior styling and a richly appointed cabin.
Inside, the Sierra emphasizes refinement as much as strength. Premium materials, advanced infotainment technology, and driver-focused controls position the Denali Ultimate as both a capable workhorse and a long-distance travel companion. It is designed to deliver heavy-duty performance without sacrificing comfort.
The giveaway runs from February 6 through May 21, 2026, with the winner scheduled to be drawn on June 3, 2026. Organizers have also confirmed that federal prize taxes will be covered for the winner, eliminating a common concern associated with high-value vehicle prizes.
Entries support veterans and children’s charities, tying the opportunity to win a premium diesel truck to a broader charitable mission.
With only four months to participate and additional entries available for Motorious readers, the window to secure this 2026 GMC Sierra 2500 Denali Ultimate is limited. When the promotion closes in late May, the chance to claim this turbo-diesel flagship pickup will be gone.
