The entry-level model, known simply as Base, covers the truck basics without a lot of extras, but it still has a decent amount of equipment. It's offered only as an extended cab, and standard features include a 2.5-liter inline four-cylinder engine (200 horsepower and 191 pound-feet of torque), a six-speed manual transmission, 16-inch steel wheels, air-conditioning, vinyl upholstery and floor covering, a four-way power driver seat with manual recline, front bucket seats, a tilt-only adjustable steering wheel, power windows, a rearview camera, and a six-speaker sound system with Chevrolet's app-based MyLink system, Bluetooth phone and audio connectivity, voice controls, Apple CarPlay and Android Auto, and a 7-inch display. There aren't too many changes when you step up to the Work Truck (WT) model, but it does come in both extended-cab and crew-cab body styles and adds fold-up rear jump seats (extended-cab models only), cloth upholstery, carpeting and floor mats. Notable options for the WT include remote keyless entry, cruise control, an EZ-Lift tailgate, and OnStar telematics (roadside assistance, turn-by-turn navigation, automatic crash response) and 4G LTE Wi-Fi hotspot connectivity. If you don't want to sort through all the WT's options sheets, you can simply spring for the LT, which gets you most of the above items, plus 17-inch alloy wheels, a leather-wrapped tilt-and-telescoping steering wheel, an 8-inch touchscreen, satellite radio, in-car 4G LTE Wi-Fi, and two additional USB ports. More options are available for the LT, with the most notable ones being heated front seats, automatic climate control, heated exterior mirrors, and forward collision and lane departure warning systems. For more luxury items and some mild off-road ability, you'll want to check out the Z71. It comes standard with most of the LT's optional equipment, plus it adds dark-tinted 17-inch alloy wheels, all-terrain tires (instead of all-season tires), an off-road-oriented suspension, a lock
