GMC has just pulled the covers off the 2026 GMC Ultra Beast Truck, and it’s turning heads already. This new model takes the tough Sierra lineup and cranks it up with a more aggressive design. The front grille is bigger and bolder, paired with sharp LED lights that give it a mean stare. The hood has strong lines, and the whole body looks ready to tackle anything. It’s not a complete redesign, but these updates make it feel fresh and commanding on the road.
Powerful Engine Options
The top choice is the 6.2L V8 engine, pumping out around 420 horsepower and tons of torque. It’s perfect for hauling heavy loads or quick acceleration. There’s also a turbocharged 2.7L four-cylinder for better everyday driving, and a durable diesel option for those who need max towing – up to 13,300 pounds in some setups. GMC even added mild-hybrid tech in some versions to smooth things out and save a bit on fuel. Paired with a 10-speed automatic, it shifts nicely whether you’re on the highway or off-road.
Smart Technology Inside
The cabin is quiet and comfy, with premium materials like leather seats that heat, cool, and even massage in higher trims. The big 13.4-inch touchscreen handles infotainment easily, with wireless Apple CarPlay and Android Auto. There’s a 12.3-inch digital gauge cluster too. Safety tech is top-notch: adaptive cruise control, lane-keeping assist, blind-spot monitoring, and automatic braking come standard on most models. GMC’s Super Cruise hands-free driving is available for long trips – it works on many highways and makes towing less stressful.
Mileage and Efficiency
The base turbo four gets around 20-22 mpg combined, which is decent for a big truck. The V8 drops to about 16-18 mpg, but it’s built for power, not sipping gas. The diesel shines here, hitting up to 25 mpg on the highway – great if you drive a lot or tow often. With rising gas prices, the hybrid touches help a little without losing that beastly feel.
Price and Trims
The base Pro trim is around $40,000, good for work folks who want reliability. Move up to SLE or SLT for more comforts, landing in the $50,000 range. The loaded Denali Ultimate or off-road AT4 versions push $70,000+, adding luxury and capability. It’s competitive with Ford F-150 or Ram 1500, but GMC’s premium vibe makes it feel special.
