The Silverado 1500 is available with a variety of engines. In fact, Chevrolet offers a total of six different engines in the Silverado for 2021, ranging from a 3.0L diesel engine, all the way up to a 6.2L V8 that makes 425 horsepower. Transmission options include both 8-speed and 10-speed automatics depending on trim level. Like most trucks in this class, power is generally sent to the rear wheels, though 4-wheel drive is available. The base Chevrolet Silverado trim is known simply as "Work Truck". The Work Truck trim is aimed at people who rely on their trucks as a tool and who care more about its function than how many speakers the stereo has. The Work Truck comes appropriately with cloth seats, 17-inch steel wheels and blacked out trim. However, it's still 2021, so the Silverado also gets a 7-inch touchscreen - even in the Work Truck. The Custom trim is one step up and adds a little visual pizzazz to the truck. 20-inch wheels come standard as do LED tail lamps. And for those who want to sound as good as they look, an integrated dual exhaust system is available as well. The Custom Trail Boss takes the Custom trim and adds various off-roading goodies. The Trail Boss gets a 2-inch lift, rancho shocks, a rear locking differential, skid plates and off-road tires. The LT trim offers chrome accents along the bumpers and front grille, LED headlamps, daytime running lamps and a bigger 8-inch touchscreen inside. The RST is one step up from the LT, adding full LED lighting that includes the fog lamps, headlights and tail lamps. Body colored trim and 22-inch wheels are also included. Like the Custom, the LT is available in Trail Boss form, combining the features of the LT with the off-road suspension and skid plates. The LTZ trim moves fully into luxury vehicle territory with additional exterior chrome accents, power folding mirrors, leather trimmed seats and lots of interior goodies. The top-of-the-line High Country trim offers a power tailgate, chrome assist steps and a very cool two-tone grille design with chrome and bronze finishing.
