The Chevrolet Colorado diesel is one of the most capable midsize trucks in its class, especially when equipped with the 2.8L Duramax turbo-diesel engine.
Known for its strong low-end torque and impressive towing efficiency, it has become a popular choice for drivers who need near full-size truck capability in a more fuel-efficient and maneuverable package.

Understanding the Diesel Towing Advantage
The diesel version of the Colorado stands out due to its high torque output, which reaches approximately 369 lb-ft. Unlike gasoline engines that build power at higher RPMs, diesel engines deliver pulling strength at lower RPMs.
This makes a significant difference when towing heavy loads, especially on steep inclines or long highway stretches.
The 7,700 lbs maximum towing capacity is achieved only when the truck is properly equipped with:
- 2.8L Duramax diesel engine
- Trailering package
- Proper axle ratio
- 2WD or optimized 4WD configuration
- Factory-installed hitch setup
Without these configurations, the towing capacity may be lower, depending on the trim and equipment.

Trim-Level Impact on Towing
Although all diesel trims of the Colorado share the same engine, towing performance can vary slightly depending on configuration.
WT (Work Truck)
The WT trim is the most basic configuration, but often provides the highest practical towing efficiency due to fewer added accessories that increase weight. It is commonly used in fleet and work environments.
LT Trim
The LT offers a balance between comfort and capability. While towing capacity remains the same on paper, added features slightly increase curb weight, which can affect payload before reaching maximum towing limits.
Z71 Trim
The Z71 is designed for off-road capability. Features like skid plates, off-road suspension tuning, and all-terrain tires add weight and slightly reduce real-world payload margins, though towing capacity remains rated up to 7,700 lbs.

Diesel Engine Performance Breakdown
The 2.8L Duramax diesel engine is the heart of the towing capability. Key performance specifications include:
- Horsepower: ~181 hp
- Torque: ~369 lb-ft
- Transmission: 6-speed automatic
- Turbocharged diesel configuration
While horsepower is moderate compared to gasoline V6 engines, the torque output is what enables strong towing performance. This makes the Colorado diesel especially efficient for hauling heavy loads without excessive strain.
Real-World Towing Applications
The diesel Colorado is commonly used for:
- Small to medium travel trailers
- Boats and fishing rigs
- Utility and cargo trailers
- Landscaping and construction equipment
- Farm and rural utility hauling
Because of its midsize design, it offers better fuel efficiency than full-size trucks while still maintaining strong towing capability.

Fuel Efficiency and Towing Balance
One of the biggest advantages of the diesel Colorado is its fuel economy when towing. Compared to gasoline variants, the diesel engine generally delivers better mileage under load, especially on highways.
This makes it ideal for long-distance towing where fuel stops can become costly and time-consuming. Many users choose the diesel specifically for its balance between power and efficiency.
Important Towing Considerations
Even though the Colorado diesel is rated for 7,700 lbs, real-world towing depends on several factors:
- Passenger and cargo weight inside the truck
- Trailer type and aerodynamics
- Road grade and terrain
- Weather conditions
- Proper hitch and braking systems
Exceeding payload limits can reduce safe towing capacity even if the maximum rating is higher.
Why the Colorado Diesel Was Discontinued
The diesel engine was discontinued after the 2022 model year in the U.S. due to changing emissions regulations and shifting market demand toward gasoline and newer turbocharged engine platforms. However, used diesel Colorado models remain highly sought after for towing-heavy applications.
Final Thoughts
The Chevrolet Colorado diesel remains one of the most capable midsize towing trucks ever produced in its segment. Across all model years from 2016 to 2022, it consistently delivers up to 7,700 lbs of towing capacity when properly equipped.
Its combination of diesel torque, solid fuel efficiency, and midsize practicality makes it an excellent choice for drivers who need dependable towing performance without moving into a full-size truck category.
