The Sierra 1500 brings together the refinement, innovation, and capability you expect from GMC. Refinement is highlighted by the Sierra's exceptionally quiet and spacious interior. Innovations like Active Fuel Management and improved aerodynamics, help Sierra get more than 300 horsepower and an EPA estimated 20 mpg highway from a V8 engine.(1) The power of an available 403 hp 6.2L V8 engine with 417 lb-ft of torque and class leading 16,000 lb towing capacity make the all-new Sierra capable of handling any job.
