Introduction
The 2021 Chevrolet Colorado Crew Cab Long Box with the 3.6L V6 and 4WD automatic transmission represents a mid-cycle refresh of the second-generation Colorado, which debuted in 2015. Positioned within the highly competitive mid-size truck segment – facing rivals like the Toyota Tacoma, Ford Ranger, and Nissan Frontier – the Colorado aimed to offer a blend of capability, refinement, and technology. The facelift brought updated exterior styling, an enhanced interior, and improved technology features. This particular configuration, with the longer bed and crew cab, catered to buyers needing both passenger space and substantial cargo capacity. The 4WD system further broadened its appeal to those requiring all-weather or off-road capability.
Powertrain & Engine Architecture
At the heart of this Colorado variant lies the LGZ 3.6-liter V6 engine. This engine is a naturally aspirated, 60-degree V6 featuring direct fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT). The LGZ engine is known for its relatively smooth operation and adequate power delivery. The direct injection system optimizes fuel combustion, contributing to improved efficiency and power output. The engine produces 308 horsepower at 6800 rpm and 275 lb-ft of torque at 4000 rpm. This power is channeled through an eight-speed Hydra-Matic automatic transmission, a crucial component in delivering a refined driving experience. The Hydra-Matic transmission is designed for smooth and efficient gear changes, and its eight forward ratios help to keep the engine operating in its optimal power band. The transmission is electronically controlled, adapting to driving conditions and driver input.
Driving Characteristics
The 2021 Colorado 3.6L V6 4WD Automatic delivers a competent and comfortable driving experience. While not as overtly sporty as some competitors, the powertrain provides sufficient power for everyday driving and hauling moderate loads. The eight-speed automatic transmission contributes to smooth acceleration and helps maintain reasonable fuel economy. Compared to the available 2.5-liter four-cylinder engine, the V6 offers a significant performance advantage, particularly when towing or carrying heavy payloads. Against the diesel option (Duramax), the V6 trades some low-end torque and fuel efficiency for a lower initial cost and potentially simpler maintenance. The 4WD system provides enhanced traction in slippery conditions, making it suitable for both on-road and light off-road use. The long wheelbase contributes to a stable ride, but can also make maneuvering in tight spaces slightly more challenging.
Equipment & Trim Levels
The 2021 Colorado Crew Cab Long Box 3.6L V6 4WD Automatic typically came standard with a respectable array of features. These included an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and keyless entry. Higher trim levels, such as the LT and Z71, added features like leather upholstery, heated front seats, a premium audio system, and advanced safety technologies such as forward collision alert and lane departure warning. Optional extras included a spray-in bedliner, a trailering package, and various appearance upgrades. Interior upholstery generally consisted of cloth on lower trims, with leather available on higher-end models. The dashboard layout was functional and straightforward, prioritizing ease of use.
Chassis & Braking
The Colorado II utilizes a body-on-frame construction, providing a robust and durable platform for truck duties. 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 the front discs measuring 310mm and the rear discs measuring 324mm. An Anti-lock Braking System (ABS) is standard. The steering system is a rack-and-pinion setup with electric power steering, providing responsive and precise handling. Tire sizes varied depending on the trim level, with 255/65R17 and 265/60R18 being common options.
Market Reception & Comparison
The 2021 Chevrolet Colorado received generally positive reviews, with critics praising its comfortable ride, capable V6 engine, and user-friendly technology. However, some reviewers noted that its interior materials weren’t as premium as those found in some competitors. Fuel economy was considered average for the segment. Compared to the four-cylinder Colorado, the V6 offered a noticeable performance improvement, justifying the higher price for buyers prioritizing power. The diesel-powered Colorado offered superior fuel economy and towing capacity, but at a significant cost premium. The Colorado generally held its own against the Toyota Tacoma in terms of capability and reliability, while the Ford Ranger offered a more modern driving experience.
Legacy
The LGZ 3.6L V6 engine paired with the Hydra-Matic 8-speed automatic transmission has proven to be a relatively reliable powertrain in the Colorado. While not without its occasional issues (such as potential oil consumption in some cases), it generally provides years of dependable service with proper maintenance. In the used car market, the 2021 Colorado 3.6L V6 4WD Automatic remains a popular choice for buyers seeking a well-rounded mid-size pickup truck. Its combination of capability, comfort, and technology continues to make it a competitive option in its class. Its longevity and relatively straightforward maintenance requirements contribute to its ongoing appeal.
