The 2020 Chevrolet Colorado arrived at a pivotal moment for the midsize pickup segment. As competition from the resurrected Ford Ranger and the perennial favorite Toyota Tacoma intensified, the Colorado leaned into its greatest strength: variety. This model year solidified the Colorado as a truck capable of being many things to many people, ranging from a stripped-down fleet vehicle to a sophisticated rock crawler. Understanding the nuances of the 2020 model requires looking past the spec sheet and evaluating how its diverse configurations handle real-world demands.

Understanding the 2020 Colorado Powertrain Options

Engine choice is the defining characteristic of any pickup truck, and in 2020, Chevrolet offered one of the most diverse lineups in the midsize class. Unlike competitors that often restricted buyers to a single turbocharged four-cylinder or a high-displacement V6, the Colorado provided three distinct paths, each catering to a different operational philosophy.

The Fuel-Efficient 2.5L Four-Cylinder

The entry-level engine for the 2020 Colorado was a 2.5-liter naturally aspirated four-cylinder. Producing 200 horsepower and 191 lb-ft of torque, this engine was paired exclusively with a six-speed automatic transmission. In a market increasingly obsessed with high-output numbers, the 2.5L served as a pragmatic solution for urban fleet operations and light-duty commuting.

In real-world driving, the 2.5L engine is adequate for unladen travel. However, its limitations become apparent during highway merging or when the bed is near its maximum payload. For buyers seeking a daily driver that prioritizes lower initial purchase prices and reasonable fuel economy over raw power, this configuration represents the most accessible entry point into truck ownership.

The Robust 3.6L V6 Workhorse

For the vast majority of Colorado owners, the 3.6-liter V6 is the engine that defines the experience. Generating 308 horsepower and 275 lb-ft of torque, this engine features cylinder deactivation and is mated to a more sophisticated eight-speed automatic transmission. The shift from the six-speed to the eight-speed was a significant upgrade in previous years, providing smoother gear transitions and keeping the engine in its power band more effectively.

The V6 offers a crisp throttle response and a surprising amount of top-end power. On the road, this translates to confident passing maneuvers and a truck that feels surprisingly nimble for its size. It is the "goldilocks" engine of the lineup, balancing refined daily driving manners with enough capability to handle the 7,000-pound maximum towing capacity when properly equipped.

The Class-Leading 2.8L Duramax Turbo-Diesel

The 2.8-liter Duramax turbo-diesel four-cylinder remained the 2020 Colorado’s trump card. While its 181 horsepower might look underwhelming on paper, its 369 lb-ft of torque is the figure that matters. This engine transforms the Colorado into a specialized towing machine.

Experienced truck users value the diesel not just for the torque, but for the driving dynamics it provides. The inclusion of an integrated exhaust brake—a feature typically reserved for heavy-duty trucks—allows the Colorado to manage steep descents with a heavy trailer with significantly less wear on the traditional braking system. Furthermore, the diesel variant consistently delivered superior fuel economy, particularly during long-distance highway cruising, making it the preferred choice for those who frequently venture into the backcountry or tow small campers and boats.

Performance Specs and Towing Capabilities

The 2020 Colorado was engineered to bridge the gap between lifestyle vehicles and traditional work trucks. Its performance specifications reflect a focus on utility without the unwieldy footprint of a full-size Silverado.

Towing Limits by Engine Configuration

Towing capacity is often the primary metric for truck buyers. In 2020, the Colorado’s limits were highly dependent on the chosen powertrain:

  • 2.5L I4 Models: Rated for up to 3,500 lbs, making them suitable for small utility trailers or jet skis.
  • 3.6L V6 Models: Rated for up to 7,000 lbs (with the Z82 Trailering Package), allowing for the transport of most midsize boats and horse trailers.
  • 2.8L Diesel Models: Rated for a class-leading 7,700 lbs (7,600 lbs for 4x4 configurations), rivaling the capacities of some entry-level full-size pickups.

It is important to note that the off-road-focused ZR2 trim, despite its powerful engine options, sees its towing capacity capped at 5,000 lbs. This reduction is a direct result of its specialized suspension components, which prioritize wheel travel and damping over the stiffness required for maximum tongue weight.

Payload Capacity and Bed Options

The Colorado’s versatility extended to its physical dimensions. Buyers could choose between an Extended Cab with a 6-foot-2-inch bed or a Crew Cab with either a 5-foot-2-inch short bed or the 6-foot-2-inch long bed.

Payload capacities peaked at roughly 1,578 lbs for V6 models. In practice, this means the Colorado can comfortably haul a pallet of mulch, a pair of dirt bikes, or a significant amount of construction material. The bed itself featured the innovative CornerStep rear bumper, which remained one of the most ergonomic ways to access the cargo area without a deployable step.

Deciphering the 2020 Colorado Trim Levels

The 2020 lineup consisted of five primary trims, each moving the truck further from its utilitarian roots toward either luxury or extreme off-road capability.

Base and Work Truck (WT) Utility

The Base trim was essentially a "price-leader" model, often found in white and sold to commercial fleets. It featured vinyl flooring and limited power accessories, emphasizing durability and ease of cleaning over comfort.

The Work Truck (WT) trim served as the true starting point for most retail buyers. While still basic, it allowed for more customization, such as the addition of the V6 engine, 4WD, and the Crew Cab configuration. The WT trim is an excellent choice for those who want a "blank canvas" for a work vehicle or a budget-conscious build.

The Everyday Comfort of the LT Trim

The LT was the volume seller for 2020. It replaced the basic materials of the WT with higher-quality cloth upholstery, a leather-wrapped steering wheel, and body-colored exterior accents. Most importantly, it upgraded the infotainment screen to an 8-inch unit and included the EZ-Lift and Lower tailgate. For the driver who uses their truck as a primary vehicle for both work and family life, the LT provides the necessary creature comforts without the premium price tag of the off-road models.

Stepping into the Off-Road Z71

The Z71 trim served as the gateway to off-road performance. While not as extreme as the ZR2, it included an automatic locking rear differential (G80), off-road-tuned suspension, and all-terrain tires. The Z71 is often considered the best value for enthusiasts who spend 90% of their time on pavement but need reliable performance for forest service roads and weekend camping trips.

The Specialized ZR2 and ZR2 Bison

The ZR2 was the halo model of the 2020 lineup. It was not merely a lift kit and some stickers; it was a fundamentally re-engineered truck. The most significant feature was the Multimatic Dynamic Spool Valve (DSSV) dampers. Derived from Formula 1 and supercar applications, these dampers provided unparalleled control.

On-road, the ZR2 feels remarkably composed, absorbing bumps that would unsettle a Tacoma. Off-road, the widened track, front and rear electronic locking differentials, and increased ground clearance allowed it to tackle technical trails that would stop most midsize trucks in their tracks. The ZR2 Bison, a collaboration with American Expedition Vehicles (AEV), added boron steel skid plates and unique bumpers, making it one of the most "trail-ready" factory trucks ever produced.

Interior Quality and Infotainment Features

If the 2020 Colorado has a weak point, it is the interior materials. While competitors like the Honda Ridgeline offered car-like luxury, the Colorado stayed true to its truck identity with heavy use of hard plastics. While this makes the cabin durable and easy to wipe down, it lacked the "premium" feel found in some rivals.

However, Chevrolet made up for the dated plastics with excellent technology. Every 2020 Colorado came standard with the Chevrolet Infotainment 3 system, which included Apple CarPlay and Android Auto. The interface is intuitive, with large icons and physical knobs for volume and tuning—a detail often missed in modern, touch-only cabins. The available 4G LTE Wi-Fi hotspot also ensured that the truck could function as a mobile office for contractors and remote workers.

Safety Ratings and Driver Assistance Shortcomings

The safety profile of the 2020 Colorado is a mix of solid structural performance and aging technology. The NHTSA awarded the Colorado a four-star overall safety rating, with a perfect five-star rating in side-impact tests.

However, compared to the 2020 Toyota Tacoma or Ford Ranger, the Colorado lagged in active safety features. While forward collision warning and lane departure warning were available on higher trims, automatic emergency braking was notably absent from the options list. For buyers prioritizing the latest in autonomous safety suites, the 2020 Colorado requires a more cautious approach.

What Changed for the 2020 Model Year?

2020 was a year of refinement rather than revolution for the Colorado. The most significant change was the discontinuation of the six-speed manual transmission, which had previously been available on the base four-cylinder models. This move reflected the declining demand for manuals in the pickup segment.

Other updates included:

  • Tire Fill Alert: This system provides an audible chirp when the tires reach the correct pressure during inflation—a small but highly useful feature for those who frequently air down for off-roading.
  • Infotainment Updates: The transition to Infotainment 3 brought a faster processor and clearer graphics.
  • Tailgate Locking: The tailgate lock could now be operated via the key fob, enhancing cargo security.

Buying a Used 2020 Chevy Colorado in Today's Market

For those looking at the 2020 Colorado in the used market, it represents a strong value proposition. Because it was the final year before the 2021 facelift (which featured the more aggressive "Chevrolet" embossed tailgate and updated grilles), 2020 models can sometimes be found at a slight discount compared to their newer counterparts despite having nearly identical mechanical components.

When inspecting a used 2020 model, buyers should pay close attention to the transmission history, particularly on V6 models. While the eight-speed automatic is generally robust, ensuring that all software updates and fluid services have been performed is crucial for long-term reliability. For those looking at the diesel, checking the DEF (Diesel Exhaust Fluid) system and ensuring the truck hasn't spent its entire life in short-trip city driving (which can clog the DPF) is essential.

Summary

The 2020 Chevy Colorado remains a standout in the midsize truck segment due to its "choose your own adventure" approach to configuration. Whether configured as a budget-friendly 2.5L Work Truck, a cross-country towing 2.8L Diesel LT, or a hardcore ZR2 Bison, the Colorado delivers a level of mechanical honesty and capability that is hard to find. While its interior may show its age and its safety tech is basic by modern standards, its core engineering—the engines, the chassis, and the specialized off-road hardware—continues to hold its own against much newer competition.
