The 2019 Chevrolet Silverado is 450 pounds lighter than the previous model-year, features a wider bed, and offers a wider range of trims and engine/transmissions combinations, including a new turbo-diesel engine.

The 2019 Silverado offers a box that is 7-inches wider, and 1-inch longer than the current truck, and includes a power tailgate that can now be opened or closed by key fob, General Motors announced at the North American International Auto Show.

GM will be offering the new Silverado with six available engine and transmission combinations, which includes the all-new Duramax 3.0L inline-six turbo-diesel engine. Also available are the new 5.3L and 6.2L V-8s with available Dynamic Fuel Management that actively shuts off any number of cylinders, in a variety of combinations, depending on immediate needs to optimize fuel economy, GM said. 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.

The 2019 Silverado includes a wheelbase that is 3.9-inches longer, with an increase in overall length of 1.6 inches. Also, a higher-grade steel is used in the bed of the vehicle, which is 88-pounds lighter than its predecessor, and it has 12 fixed tie-downs, with a strength that has doubled to 500 pounds of force before bending.

The cab itself has also been adjusted for the new model year: crew-cab models now offer 3 inches of additional rear-seat legroom for 44.5 inches of front legroom and 43.8 inches of rear legroom. Meanwhile, newly available storage options include two 10-liter bins integrated into the second-row seatbacks and a large 24-liter storage tray under the second-row seat.

Available technology for the 2019 Silverado includes 4G LTE Wi-Fi connectivity, Apple Car Play, Android Auto, wireless phone charging and OnStar safety and security features. Additional safety and convenience features will be announced later this year.

Three new trims have been added to the 2019-MY: Custom Trail Boss, RST, and LT Trail Boss.
