The 2019 GMC Sierra 1500 rests upon an entirely new platform this year. It's longer, has more interior space, and shows off a handsome exterior facelift that further differentiates itself in a meaningful way from its counter-part the Chevy Silverado. Exclusive features include adaptive dampeners, a split folding tailgate, a carbon fiber cargo box, and C-shaped lighting elements to name just a few. The Crew cabs longer wheelbase makes way for 3 more inches of leg room in the back seat. All trims are built on a lighter frame and suspension components with aluminum hood and door panels saves 360 pounds over its predecessor. Also new for 2019 is Dynamic Fuel Management, which is designed to fine-tune the balance between efficiency and power demand. It lets the engine operate anywhere between two and eight cylinders depending on load.
The GMC Sierra 1500 comes in six different drivetrain configurations and one of five distinct body styles - regular cab with a long or standard bed, crew cab with a short or standard bed, and double cab with a standard bed. Beyond that, the 1500 can be equipped with configurations that include a 4.3L V6 that produces 285 horsepower, a 2.7L turbocharged 4-cylinder that makes 310 horsepower and 348 pound-feet of torque, a 5.3L V8 making 335 horsepower and 383 lb-ft of torque with Active Fuel Management. All 1500 and Sierras come with the option of 4-wheel drive except Denali where All-wheel drive is standard. Maximum tow ratings top out at 12,200 pounds when properly equipped.
Trim levels for the 1500 come in four different flavors. Sierra, SLE, SLT and Denali.
In standard Sierra trim, the Sierra is fairly basic with automatic windows and door locks, air conditioning, Bluetooth, a USB port and Teen Driver Safety suite as standard equipment. SLE versions add OnStar, heated exterior mirrors, a leather-wrapped steering wheel and an 8-inch touchscreen audio system with six speakers. The SLT trim includes heated leather front seats, steering wheel mounted audio controls, a remote starter, dual-zone climate control, power adjustable pedals and power-folding mirrors.
Denali versions come in only one trim level and in crew cab and short-bed. Regardless of bed-length, the Sierra Denali includes an 8-inch color touch screen, 10-way power driver seat, heated driver/front passenger seats, a rear-camera mirror, a surround view camera system, MultiPro tailgate, power retractable side steps and wheels up to 20 inches in size. The Denali also comes with a unique grill and other selected trim.
