2027 Chevy Colorado: Duramax, Towing & Engine Updates – The 2027 Chevy Colorado continues as one of America’s top midsize pickups, delivering class-leading towing, strong performance, and modern capability. While the title mentions Duramax diesel, the current-generation Colorado (third-gen, launched for 2023) does not offer a Duramax diesel engine. Chevrolet simplified the lineup to a single advanced gasoline powertrain. This article covers the real story on the 2.7L TurboMax engine, expected 2027 updates, and the truck’s impressive towing credentials for U.S. buyers.
2027 Chevy Colorado Overview
The 2027 Chevrolet Colorado represents the fifth model year of the current generation. Production of the 2027 model is scheduled to begin October 19, 2026, at GM’s Wentzville, Missouri plant, with dealer ordering opening in September 2026.
Buyers can expect evolutionary changes rather than a full redesign. A mid-cycle refresh is anticipated for the 2027 or 2028 model year, bringing a revised front fascia, subtle interior upgrades, and iterative powertrain refinements to keep the Colorado competitive against the Ford Ranger, Toyota Tacoma, and Honda Ridgeline.
Duramax Diesel in the 2027 Colorado: What Buyers Need to Know
The previous-generation Colorado (2015–2022) offered a 2.8L Duramax inline-4 diesel that delivered strong low-end torque and excellent fuel economy for towing and highway driving. However, for the 2023 redesign, Chevrolet dropped the diesel, naturally aspirated four-cylinder, and V6 options in favor of a single turbocharged 2.7L gasoline engine.
No Duramax diesel is expected for the 2027 Chevy Colorado. GM has focused resources on the 2.7L TurboMax, which many reviewers say delivers diesel-like torque delivery without the added cost, DEF fluid maintenance, or emissions equipment of a diesel.
The 2.7L produces peak torque at just 3,000 rpm, giving it strong, usable pull right where you need it for towing or merging. It pairs with an 8-speed automatic transmission and is available in rear-wheel drive or four-wheel drive.
2027 Chevy Colorado Engine Specs and Expected Updates
The heart of the 2027 Colorado remains the 2.7L TurboMax inline-4 (L3B). Current high-output ratings stand at:
- 310 horsepower @ 5,600 rpm
- 430 lb-ft of torque @ 3,000 rpm
A base version of the engine (around 237 hp / 260 lb-ft) is available on lower trims for those who don’t need maximum capability.
Credible industry sources point to a meaningful power increase for the 2027 model year. Leaks suggest the TurboMax could rise to approximately 350 horsepower and 440 lb-ft of torque in higher-output configurations. This update appears tied to broader GM powertrain improvements rolling out across the Colorado/Canyon and full-size trucks.
These figures would make the Colorado even more competitive while maintaining strong real-world fuel economy and low-end response that feels diesel-inspired.
Towing Capacity: How Much Can the 2027 Chevy Colorado Tow?
When properly equipped, the 2027 Chevy Colorado is rated to tow up to 7,700 pounds — best-in-class for midsize trucks.
Towing by Configuration (Current & Expected Similar for 2027)
- Maximum towing: 7,700 lbs (with trailering package and high-output engine on appropriate trims)
- Base WT/LT trims: Around 3,500 lbs
- Z71, Trail Boss, and higher trims: Up to 7,700 lbs with the right equipment
- ZR2 off-road models: Slightly lower (around 6,000 lbs or less) due to suspension and tire setup
Key factors for achieving max towing:
- High-output 2.7L TurboMax engine
- Trailering Package (includes hitch platform, wiring harness, and integrated brake controller on many trims)
- Proper axle ratio (typically 3.42)
- Crew Cab or Extended Cab configurations with the right bed length
The Colorado also offers a maximum payload capacity of nearly 1,700 pounds, making it versatile for both towing and hauling tools, materials, or gear.
Advanced trailering features available on higher trims include a trailering app, camera views, and stability systems that make towing safer and easier for American truck buyers who regularly pull boats, campers, or utility trailers.
2027 Chevy Colorado Refresh: What’s Changing?
Expect these updates for the 2027 model year:
- Revised front fascia and updated exterior styling cues
- Iterative powertrain refinements (possible power bump noted above)
- Interior improvements and technology enhancements
- Continued focus on off-road capability with trims like ZR2 and Trail Boss
These changes are described as evolutionary, helping the truck stay fresh without a complete redesign.
Why the 2027 Chevy Colorado Stands Out for U.S. Buyers?
- Best-in-class towing for a midsize truck
- Strong, diesel-like torque from the turbocharged four-cylinder
- Modern interior with large touchscreen and available advanced driver aids
- Excellent off-road trims (Trail Boss, ZR2)
- Strong value compared to full-size trucks when you don’t need maximum size
Whether you’re towing a travel trailer to the lake, hauling a side-by-side to the trails, or just need a capable daily driver, the 2027 Colorado delivers impressive real-world performance.
Final Thoughts
While the 2027 Chevy Colorado will not bring back the Duramax diesel, its 2.7L TurboMax engine continues to provide outstanding torque, strong towing (up to 7,700 lbs), and efficiency that many owners find preferable to older diesel setups. With a likely power increase and styling refresh on the horizon, the 2027 model should remain a top choice for American truck buyers who want capability without the bulk of a full-size pickup.
