The Chevrolet Silverado 1500 LT Trailboss, a new model for 2019, adds off-road equipment to the LT, including a two-inch suspension lift and the Z71 Off-Road Package, including locking rear differential, skid plates, Rancho shocks, 18-inch wheels and Goodyear Duratrac off-road tires.

Celebrating 100 years of Chevrolet trucks, the iconic brand rolled out the newest generation of its Silverado 1500 pickup at the recent Detroit auto show, an all-new model that’s bigger than the current generation, but also lighter and tougher.

The truck was introduced on the 100th anniversary of the rollout of the first Chevrolet truck in January 1918.

The newest version arrives just five years after the current generation came on the market for 2014, and three years since a major update to those trucks for 2016. Full-size pickups are a competitive product, and the new Silverado will be competing against also all-new Ford F-150 and Ram 1500 pickups for 2019.

General Motors says the new Silverado will have a wheelbase up to 3.9 inches longer than the current model, and will be 1.6 inches longer overall. Those changes will allow for bigger cargo beds and roomier interiors for all cab sizes.

But the trucks will be lighter as well – 450 pounds less than the current model when comparing V-8 powered crew cab versions, GM says. The lighter weight is made possible by the use of mixed materials, including aluminum for doors, hoods and tailgates, and special high-strength steels in the rest of the body and the frame.

As always, the Chevy trucks will have fully-boxed steel ladder-style frames for toughness and durability.

GM promises class-leading cargo volume – 63 cubic feet for the short box, which is 20 percent more than a main competitor’s; a nearly seven-inch wider bed; and a stronger steel bed floor.

There will be storage bins available that fit over the wheel wells, Chevrolet says, with nearly seven cubic feet of lockable cargo space for short-box models. Even with these in place, the truck bed will accommodate a four-by-eight-foot sheet of plywood lying flat.

The all-new 2019 Silverado High Country features an exclusive front grille design with two-tone chrome and bronze finish and body-color accents, plus chrome assist steps from wheel to wheel. It also includes the power up/down tailgate as standard equipment.

Also included will be 12 fixed tie-downs, with their strength doubled to 500 pounds of force before bending, the automaker says. Additionally, there will be nine moveable tie-down points.

The tailgate will be available with a class-exclusive power up/down feature that can be activated through the remote key fob or an interior button, or by hand. The previously introduced CornerStep bumper continues on the new Silverado, but with larger cutouts for bigger shoes and boots. There will be a 120-volt power outlet in the bed, along with available task lighting.

Eight different models will be offered, including new Custom Trailboss and LT Trailboss off-road versions that also have the Z71 off-road equipment. The top of the line will continue to be the High Country model with lots of luxury features, including leather upholstery.

Under the hood, there will be a choice of six engine/transmission combinations, including a new Duramax inline six-cylinder diesel. Gasoline engines include new 5.3- and 6.2-liter V-8s with Dynamic Fuel Management, which shuts off cylinders in a variety of combinations, depending on driving needs, the to optimize fuel economy.

The diesel and 6.2-liter engines come with a new Hydra-Matic 10-speed automatic transmission. They also include automatic start/stop to improve fuel economy.

Some new exterior features include “CHEVROLET” stamped on the tailgate in the style of the Chevy trucks of the 1950s and ‘60s; integrated dual exhausts; and up to 33-inch tire sizes.

Chevy says the eight trim levels are divided into three “distinct buyer profiles”: “High Value” (Work Truck, Custom, Custom Trailboss); “High Volume” (LT, RST and LT Trailboss); and “High Feature,” the luxury models (LTZ and High Country).

The LTZ will have chrome accents on the bumpers, grille, mirror caps, door handles and beltline; power folding/heated outside mirrors; and a leather interior.

High Country models come with a special grille with a two-tone chrome and bronze finish; body-color accents; chrome assist steps; leather; and the power tailgate.

The new High Volume RST model will have a street-performance look that includes body-color trim, full LED lighting and up to 22-inch wheels with all-season tires.

Crew cab models, with four full-size doors, will have three inches of additional rear-seat legroom.

The all-new 2019 Silverado High Country interior features more passenger room, more storage space and more functionality. Every surface has been designed for function and ergonomics, from the rotary knob textures to the infotainment screen angle.

New optional interior storage includes two 10-liter bins integrated in the second-row seatbacks for holding small items like gloves or tie-down straps, as well as a large 24-liter storage tray under the second-row seat.

Silverado was the first pickup to offer 4G LTE Wi-Fi connectivity, Apple Car Play, Android Auto, wireless phone charging and OnStar safety and security services, and those features will be expanded and enhanced for 2019.

Later announcements will detail new safety and convenience features, Chevrolet said.

“Truck customers value capability and functionality above all else,” said Tim Herrick, GM’s executive chief engineer of full-size trucks. “Every truck — including the luxurious High Country — is a work truck with a job to do. As such, we set out to create the best tool for the job at hand, one that makes work more productive and more enjoyable, no matter what they call ‘work.’’’

Production of the 2019 Silverado will begin this summer at the Fort Wayne (Indiana) Assembly Plant, with deliveries to customers beginning in the fall, GM said.
