Used 2017 Chevy Colorado Extended Cab Trims Comparison

The entry-level model, known simply as Base, covers the truck basics without much in the way of extra fluff, 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, 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 a 4.2-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.

The major difference between the Base and Work Truck trims is the latter's exclusive list of desirable options. Essentially you can equip the Work Truck with a few tech items, optional engines and exterior trim that makes it feel less basic. From the WT level on up, you can get a six-speed automatic transmission for the base four-cylinder or one of the Colorado's two optional engines: a 3.6-liter V6 (308 hp and 275 lb-ft) paired to an eight-speed automatic transmission or a 2.8-liter turbocharged four-cylinder diesel engine (181 hp and 369 lb-ft) paired to a six-speed automatic.

Notable options that are part of packages for the WT include remote keyless entry, cruise control, and an audio system upgrade package that includes a version of Chevrolet's app-based MyLink system with Bluetooth connectivity, a 7-inch display screen, voice controls, Apple CarPlay and Android Auto, OnStar telematics and 4G LTE Wi-Fi hot-spot 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 and two additional USB ports.

More options are available for the LT, with the most notable ones being heated front seats, automatic climate control, and forward collision and lane departure warning systems.

For more luxury accoutrements and mild off-road ability, the Z71 is the next step up. 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 locking rear differential, hill descent control, unique cloth and simulated leather upholstery, and other model-specific trim pieces. And as a final touch, the LT and Z71 also offer a seven-speaker premium Bose audio system and a navigation system (an enhancement of the standard 8-inch MyLink interface).

Even with the off-road-oriented suspension, the Z71 is still more oriented toward street use. For more ability off the beaten path, the ZR2 is your truck. The ZR2 has a raised suspension with special dampers, bigger all-terrain tires, fender flares, special bodywork for improved approach and departure angles and an electronically locking rear differential. Chevy offers the V6 or the diesel engine for the ZR2.
