Power and Performance

The base trim in the 2020 Chevrolet Silverado 1500 comes with a 4.3-liter V6 engine that generates 285 horsepower and 305 pound-feet of torque. There are also four others to choose from, with the top-of-the-line a 6.2-liter V8 that produces 420 horsepower and 460 pound-feet of torque. This is the one you will want if you will need to tow, as this Chevrolet truck has a towing capacity of 13,400 pounds, which is the highest figure for its class. A 6-speed automatic transmission comes standard with all engines, but an 8- or 10-speed is available. The 2020 Chevrolet Silverado gets excellent fuel economy for its class, with EPA estimates of 23 mpg for city driving and 33 mpg for highway driving.


The Chevrolet Silverado can fit up to six people in its roomy interior. Vinyl upholstery and 4-way manually adjustable front seats are standard. Heated and ventilated front seats, 10-way power-adjustable front seats, and both cloth or leather upholstery are available. Newer Chevy cars are gaining a reputation for their many tech features, and the same is true for their trucks. Bluetooth®, Apple CarPlay™, Android Auto™, a 7-inch touch-screen infotainment, and a USB port are all standard in the 2020 Chevrolet Silverado. Upgrades include keyless entry, a Wi-Fi hot spot, HD radio, a 7-speaker Bose sound system, navigation, and wireless device charging.


Traction control, a rearview camera, and the Teen Driver system all come standard in the new Chevrolet Silverado. With the latter one, parents can control things like the volume of the radio and how fast their teen can drive. Additional safety features include lane departure warning, forward automatic emergency braking, blind spot monitoring, and a surround-view camera system.
