Four Engines with Distinct Strengths
The Sierra offers four engines, each paired with a 10-speed automatic transmission. The enhanced 2.7L TurboMax™ develops 350 hp and 455 lbs. ft. of torque, impressive figures for a turbocharged 4-cylinder. The new 5.7L V8 produces 402 hp and 428 lbs. ft. of torque, while the available 6.6L V8 delivers 481 hp and 501 lbs. ft. of torque. A 3.0L Duramax® Turbo-Diesel contributes 305 hp and 495 lbs. ft. of torque. With an available 34-gallon fuel tank, the diesel is particularly interesting for extended highway journeys.
Towing Capability That Earns Its Keep
Maximum towing capacity reaches 13,500 lbs. when properly equipped with the 5.7L V8. That's substantial capability for transporting snowmobiles, recreational trailers, and equipment across Crawford County. Available integrated trailer brake controls, camera technology, and the ProGradeâ„¢ Trailering System help manage compatible trailers. Payload ratings depend on cab, drivetrain, and equipment, making the individual truck's specifications essential reading before loading up.
AT4 and AT4X: More Than Appearance Packages
The AT4 introduces a factory-installed 2-inch suspension lift, all-terrain tires, skid plates, and specialized suspension tuning. The AT4X takes matters further with Multimatic DSSVâ„¢ dampers, electronic-locking front and rear differentials, and 35-inch mud-terrain tires. These are meaningful mechanical upgrades for uneven forest tracks and snow-covered access roads. Available 4WD and selectable drive modes provide additional flexibility, although neither substitutes for appropriate winter tires when roads become icy.
A Digital Cabin with Working Advantages
The redesigned Sierra offers an available 16.3-inch infotainment display and 11.5-inch passenger screen. Select configurations provide more than 60 inches of combined digital display space, incorporating vehicle information and controls. Google built-in supports navigation and voice commands, while available cameras deliver up to 19 views for maneuvering and trailer connections. Super Cruise® provides hands-free assistance on compatible highways, including supported trailering applications. Drivers must remain attentive, particularly when winter weather limits system operation.
From PRO Workhorse to Denali Luxury
The 2027 lineup includes PRO, Elevation, AT4, AT4X, Denali, and Denali Ultimate. PRO concentrates on essential capability, while Elevation adds distinctive styling and convenience equipment. AT4 and AT4X prioritize demanding terrain. Denali and Denali Ultimate introduce premium appointments, including available heated and ventilated seating, Bose® audio, and a panoramic sunroof. Heated steering wheels and remote start on appropriately equipped models make freezing Michigan mornings considerably more agreeable.
A Cargo Bed Designed for Real Work
The available six-function MultiProâ„¢ Tailgate provides different arrangements for accessing and loading the bed, including a full-width step and inner-gate work surface. It's standard on select trims, including Elevation, AT4, AT4X, Denali, and Denali Ultimate. Available LED cargo lighting, integrated tie-downs, and a spray-on bedliner further support hauling tools and winter equipment.
