All of this results in a seven-percent improvement in aerodynamics, according to Chevrolet. In other words, the beds are bigger, tougher and more useful.

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. The LTZ and High Country, like today's Silverado, represent the more luxurious end of the spectrum. That means more space in the cargo box, and in the cab. A spoiler on the back of the cab helps with airflow, boosting aerodynamics and efficiency. The truck's frame is made of 80 percent high-strength steel.

Chevy saved weight by using light materials in targeted applications, including aluminum for the doors hood and tailgate. The live-axle rear suspension also gets new carbon-composite second-stage springs on LT models that save about 12 pounds per side over the steel springs they replace.

As for the bed, there Chevrolet has some fighting talk for Ford.

At the preview of the Silverado on Saturday, GM's product development chief Mark Reuss took yet another shot at the competition, saying "I don't think you can get much work done with an aluminum hammer". There are now 21 tie-down points, twelve of which are fixed in the corners - each capable of handling 500 pounds, twice what the current model can deal with - and nine of which are movable. The bed and frame make extensive use of high-strength steel.

Among the class-exclusive features, General Motors gave to the Silverado is the power up/down tailgate, which can be operated in three ways: by hand, pressing a button in the cabin, and from the key fob. 120V AC outlets are optional.

There's still more to learn about the all-new 2019 Silverado. For the 2019 model year, there'll be eight Silverado models, in fact.

The Trailboss represents the top off-roader for Chevy and sports a 2-inch factory lift, chunkier tires, and the Z71's suspension. An available 3.0-liter turbodiesel will be available in the Silverado 1500 later, officials said.

Full powertrain details have not been announced, but the Silverado will be available with a 3.0-liter diesel engine and 10-speed automatic transmission combo that Reuss expects to outperform the upcoming F-150 diesel. For reference, the Ram's 3.0 liter EcoDiesel engine delivers just 10 HP and 20 lb-ft less than Ford's diesel equivalent. Inside, there'll be Apple CarPlay, Android Auto, wireless charging for your smartphone, and the option of 4G LTE with a WiFi hotspot. The 2019 model year is up to 450 pounds lighter than the previous Silverado, and in total, Chevrolet offers eight flavors of the workhorse with six engine-transmission choices. As for when it will go on sale, and for how much, the automaker hasn't said.
