Chevrolet’s midsize pickup, the Colorado, has a new look for the model year 2021. The previous Chevrolet emblem on the tailgate is gone; instead, it says “Chevrolet” across the tailgate. It also gets a fresh front-end design with more prominent styling features for various Colorado trim levels.

The Colorado ZR2, the off-road variant of the truck, sees a number of substantial modifications. For 2021, the ZR2’s new front fascia has a more prominent and wider-open grill that extends farther and lower than the previous version. The remainder of the Colorado for 2021 is largely unchanged. It has good towing and haulage capabilities as well as an available diesel engine, which is unusual for a midsize vehicle.


For a good all-around truck, get the midlevel LT trim. Cruise control and a remote locking tailgate are among the LT’s attractive amenities that aren’t available on the Work Truck model. It also enables you to access features such as automatic climate control and an upgraded 8-inch touchscreen infotainment system.

If you’re having trouble deciding between the Colorado’s engine options, we recommend opting for the bigger V6. Although the diesel gives the Colorado an unmistakable big-rig appearance, it’s difficult to justify given its high cost.

The Chevrolet Colorado has established itself as one of the finest midsize trucks on the market by combining excellent road manners with outstanding off-road performance and day-to-day use. This two-time MotorTrend Truck of the Year winner comes in a variety of configurations, including gasoline or diesel, and short or long bed. Trim levels range from basic work vehicles to off-road-oriented ZR2 models for those who want a truck that can handle any challenge or go fast in the dunes.

The Colorado’s towing and hauling are not as robust as those on a full-size truck, but they match the capabilities of most full-size SUVs. The distinction is that the Colorado’s bed can haul big and unwieldy goods that would be difficult to transport in an SUV cargo space. With its optional diesel engine, the Colorado can tow up to 7,700 pounds, while with the V-6 it can tow up to 7,000 pounds. The standard four-cylinder engine may only tow 3,500 pounds.
