2021-2022 Chevrolet Colorado II (facelift ) Crew Cab Short Box 3.6 V6 (308 Hp) Automatic

The Chevrolet Colorado II, specifically the facelifted 2021-2022 model year Crew Cab Short Box configuration equipped with the 3.6-liter V6 engine and eight-speed automatic transmission, represents a significant iteration of Chevrolet’s mid-size pickup truck. Introduced as a more refined and technologically advanced offering, this variant aimed to compete directly with popular trucks like the Toyota Tacoma and Ford Ranger in the North American market. Positioned as a mid-range to upper-mid-range trim, it offered a balance of capability, comfort, and features appealing to both recreational users and those requiring a versatile work truck. Production of this specific configuration spanned the 2021 and 2022 model years, marking a key phase in the Colorado II’s lifecycle.

Technical Specifications

Powertrain & Engine Architecture

At the heart of this Colorado variant lies the LGZ 3.6-liter V6 engine. This engine is a naturally aspirated, aluminum-block engine featuring direct fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT). The direct injection system optimizes fuel delivery for improved efficiency and power output. The LGZ engine is known for its relatively smooth operation and respectable power delivery. The engine produces 308 horsepower at 6800 rpm and 275 lb-ft of torque at 4000 rpm. Paired with this engine is the Hydra-Matic 8L45 eight-speed automatic transmission. This transmission is designed for smooth shifting and optimized gear ratios to maximize fuel efficiency and provide adequate power for towing and hauling. The transmission’s programming is tuned to balance performance and drivability, offering both manual shift control and a tow/haul mode for enhanced capability.

Driving Characteristics

The 3.6L V6 and 8-speed automatic combination delivers a competent driving experience. While not as quick as some of the turbocharged competitors, the Colorado offers a predictable and usable powerband. Acceleration is adequate for everyday driving and highway merging, though it can feel strained when fully loaded or climbing steep inclines. The eight-speed automatic transmission helps to keep the engine in its optimal power range, providing reasonably responsive shifts. Compared to the available 2.5L four-cylinder engine, the V6 offers a significant performance upgrade. However, it doesn’t match the low-end torque of the Duramax diesel option. The gear ratios are tuned for a balance between fuel economy and towing capacity, with lower gears providing ample torque for hauling and higher gears optimizing fuel efficiency during highway cruising.

Equipment & Trim Levels

The 2021-2022 Colorado Crew Cab Short Box 3.6L V6 typically came standard with features such as an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and a suite of safety features including forward collision alert and automatic emergency braking. Higher trim levels, such as the LT and Z71, added features like leather upholstery, heated front seats, a premium audio system, and off-road-focused equipment like skid plates and an upgraded suspension. Optional extras included a sunroof, navigation system, and a trailering package. Interior upholstery generally consisted of cloth on lower trims and leather on higher trims. Dashboard configurations were relatively consistent across trims, with a focus on functionality and ease of use.

Chassis & Braking

The Colorado II utilizes a body-on-frame construction, providing a robust platform for hauling and towing. The front suspension features independent coil springs, while the rear suspension employs a traditional leaf spring setup. This configuration balances ride comfort with load-carrying capacity. Braking duties are handled by disc brakes on all four wheels, with front discs measuring 310mm and rear discs measuring 324mm. An Anti-lock Braking System (ABS) is standard. The chassis is designed to handle the weight and stresses associated with truck use, offering a stable and controlled driving experience. Stabilizer bars are included to reduce body roll during cornering.

Market Reception & Comparison

Critics generally praised the 2021-2022 Colorado V6 for its comfortable ride, user-friendly technology, and capable powertrain. However, some reviewers noted that the interior materials felt somewhat dated compared to newer competitors. Fuel economy was considered average for the segment, with the V6 engine returning around 18 mpg in the city and 25 mpg on the highway. Compared to the four-cylinder Colorado, the V6 offered a noticeable performance improvement, but at the cost of slightly lower fuel economy. The diesel option provided superior towing capacity and fuel efficiency but came with a higher price tag. Reliability reports generally indicated that the LGZ V6 engine and 8L45 transmission were relatively reliable, though some owners reported minor issues with the infotainment system.

Legacy

The Chevrolet Colorado II, particularly the 3.6L V6 Automatic variant, has established itself as a solid and dependable mid-size pickup truck in the used car market. The LGZ engine and 8L45 transmission have proven to be relatively durable, with many examples exceeding 100,000 miles with proper maintenance. While not the most fuel-efficient or technologically advanced truck in its class, the Colorado offers a good balance of capability, comfort, and value. Its robust construction and readily available parts make it a popular choice for those seeking a practical and reliable pickup truck for work or recreation. The 2021-2022 facelifted models, with their updated styling and improved features, are generally considered to be the most desirable versions of the Colorado II.
