Trims, Powertrains, and Performance

The 2026 Silverado is built in nine trims: the WT (Work Truck), Custom, Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, High Country, and ZR2. As mentioned, Chevy presents a selection of four powertrains with varying availability on specific trims. The standard powertrain on the first six trims couples a TurboMax engine (310 horsepower and 430 lb.-ft. of torque) to an 8-speed automatic transmission with electronically controlled overdrive, Tow/Haul mode, powertrain grade braking, and cruise grade braking. The LTZ and High Country pair a 5.3-liter EcoTec3 V8 engine (355 hp and 383 lb.-ft. of torque) with a 10-speed Electronic Precision Shift automatic transmission (both components are available on the WT, Custom Trail Boss, LT, RST, and LT Trail Boss). The ZR2 retains the 10-speed transmission but it’s mated to the proprietary 3-liter Duramax Turbo Diesel engine, which generates 305 hp and 495 lb.-ft. of torque (it’s available on the Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, and High Country). A 6.2-liter EcoTec V8 (420 horsepower, 460 lb.-ft. of torque) is also an option on the RST and higher.

The Silverado offers two-wheel (2WD) or four-wheel (4WD) drivetrain options—4WD models have a single-speed Autotrac transfer case with 2WD Hi, 4WD Auto, 4WD Hi, and Terrain modes. The nameplate’s maximum towing limit is 13,300 pounds on 2WD versions with the double cab/standard bed or the crew cab/short bed configurations, and the Duramax Turbo Diesel engine with the Max Trailering Package. The 2,260-pound maximum payload capacity is reached when 2WD models are paired with the regular cab/long bed configuration and outfitted with the TurboMax engine.
The ZR2 leads the lineup in fuel efficiency, at an estimated 20 mpg city and 23 mpg highway with its standard Duramax Turbo Diesel V8. The WT, Custom, LT, RST, and LT Trail Boss all follow with an estimated 17 city and 20 highway mpg thanks to their TurboMax powerplant. Next are the LTZ and High Country, whose EcoTec3 V8 achieves roughly 16 city/19 highway mpg, and the Custom Trail Boss brings up the rear with approximately 16 city/17 highway mpg. 

The regular cab, which seats three passengers with a 40/20/40 split bench, is exclusive to the WT and can be paired with either the 79.4-inch standard bed or the 98.2-inch long bed. The 6-seater double cab, with front and rear benches, is available on the WT, Custom, LT, and RST trims and is made only with the standard bed. The 5-passenger crew cab, which replaces the front-row bench with a pair of bucket seats, is offered for the entire lineup when it’s paired with the 69.9-inch short bed; with the standard bed, it’s available on every trim except the ZR2.
