The 2019 Silverado is larger than before, including a wheelbase that is up to 3.9 inches (100 mm) longer and an overall length that is 1.6 inches (41 mm) longer, enabling both more cargo volume and more interior room for all cab lengths. Remarkably, it’s also lighter, weighing 450 pounds (204 kg) less than today’s truck when comparing crew cab V-8 models.
The weight savings comes from extensive use of mixed materials and advanced manufacturing processes throughout the next-gen truck. This allowed Chevrolet to use the right material for the application and optimize every component for mass, durability, safety and functionality to meet our customers’ needs.
For example, the body is 88 pounds (40 kg) lighter than before due to mixed materials use. All exterior swing panels (doors, hood and tailgate) are made of aluminum while fixed panels (fenders, roof and bed) are made of steel. The underlying safety cage uses seven different grades of steel, each tailored for the specific application.
The fully boxed steel frame is also 88 pounds (40 kg) lighter than its predecessor, while offering 10 percent greater torsional rigidity. Eighty percent of the frame is made of high-strength steel varying from 2 to 5 millimeters in thickness, and every millimeter is optimized for performance using a variety of processes, including hydroforming, roll forming, conventional stamping and tailor-rolled blanking. As a result, frame sections, gauges, grades, processes and materials strategically vary to maximize strength, durability and stiffness without adding unnecessary mass.
Mixed materials also play a part in the all-new suspension. The front independent short/long arm suspension features new forged-aluminum upper control arms that are lighter and provide better wheel alignment than the stamped component they replace. The live-axle rear suspension is also redesigned, including new carbon-composite second-stage springs on LT models that save about 12 pounds (5 kg) per side over the steel springs they replace.
The 2019 Silverado will be available with six engine/transmission combinations, giving customers more combinations of performance, efficiency and value to best fit their priorities. This includes new 5.3L and 6.2L V-8s with industry-first Dynamic Fuel Management that actively shuts off any number of cylinders, in a variety of combinations, depending on immediate needs to optimize fuel economy. The result of this industry-first technology is instant power when called for, and impressive efficiency.
The Silverado will also be available with an all-new Duramax 3.0L inline-six turbo-diesel. Chevrolet offers diesel engines in more segments and models than any other brand, including Equinox, Cruze, Colorado, Express, Silverado 1500, Silverado HD and upcoming Silverado medium-duty models.
Both the 3.0L diesel and 6.2L engines are paired with a new Hydra-Matic 10-speed automatic transmission as well as start/stop technology to improve fuel economy for optimum performance and efficiency.
