EPA Fuel Economy: 22 MPG Combined

The 2021 Chevrolet Colorado 2.7L Turbo 4-cylinder Crew Cab delivers a combined EPA fuel economy rating of 22 MPG, making it a competitive choice in the midsize truck segment. This rating reflects the balance between the truck’s powerful turbocharged engine and modern efficiency technologies. The 2.7L turbo engine produces strong performance while maintaining reasonable fuel consumption for a vehicle of this size and capability. Whether you’re using your Colorado for daily commuting, weekend adventures, or light hauling, the 22 MPG combined rating provides predictable fuel costs and extended range between fill-ups.

Turbocharged engines like the one in this Colorado offer an interesting advantage in the efficiency equation. By forcing more air into the combustion chamber, the turbocharger enables the smaller 2.7L displacement to produce substantial power without the fuel penalty of a larger naturally aspirated engine. The 8-speed automatic transmission further optimizes efficiency by keeping the engine in its most efficient operating range across various driving conditions. This combination of technologies helps the 2021 Colorado achieve competitive fuel economy while maintaining the towing and hauling capabilities truck buyers expect.

City vs Highway Performance

The 2021 Chevrolet Colorado 2.7L Turbo achieves 20 MPG in city driving and 24 MPG on the highway. This 4 MPG difference between city and highway ratings is typical for turbocharged engines and reflects real-world driving patterns. City driving involves frequent acceleration, deceleration, and idling, which forces the engine to work harder and consume more fuel. Highway driving at steady speeds allows the turbo engine to operate more efficiently, with the transmission locked into a higher gear and consistent throttle input.

The Colorado’s highway efficiency of 24 MPG demonstrates the advantage of cruising at steady interstate speeds in this truck. Drivers who spend significant time on highways will see better fuel economy than those primarily navigating city streets. However, the 20 MPG city rating remains respectable for a turbocharged truck, especially considering the Colorado’s capability and size. Real-world city driving will vary based on traffic conditions, driving style, and local road layouts.

Annual Fuel Cost

Based on EPA estimates of 22 MPG combined, driving 15,000 miles per year, and assuming a fuel price of $3.50 per gallon, here’s the fuel cost calculation for the 2021 Chevrolet Colorado 2.7L Turbo Crew Cab:

Annual Fuel Cost Calculation:
Miles per year: 15,000
EPA Combined MPG: 22
Gallons needed annually: 15,000 ÷ 22 = 681.82 gallons
Cost per gallon: $3.50
Annual fuel cost: 681.82 × $3.50 = $2,386.36

This annual fuel cost estimate provides a baseline for budgeting. Actual costs will vary based on your local fuel prices, driving habits, and the mix of city versus highway miles you accumulate. Drivers with longer highway commutes may see costs closer to the lower end, while those in heavy city traffic might experience slightly higher expenses.

Real-World MPG Expectations

EPA fuel economy ratings represent standardized test conditions that don’t always match real-world driving. Most 2021 Colorado 2.7L Turbo owners report fuel economy within 1-2 MPG of the EPA estimates, though some variation is normal. Several factors influence actual MPG: aggressive acceleration consumes more fuel, while smooth driving preserves efficiency. Tire pressure significantly impacts fuel economy—underinflated tires increase rolling resistance and reduce MPG. Heavy loads reduce efficiency, and towing decreases fuel economy by several miles per gallon depending on load weight and trailer aerodynamics.

Weather conditions also play a role, with cold temperatures temporarily reducing efficiency as the engine requires enriched fuel mixtures during warm-up. Highway driving typically yields results closer to the 24 MPG rating, while city driving usually settles around 18-21 MPG for most drivers. Using cruise control on highways helps maintain consistent speed and improves efficiency compared to varying throttle input.

How It Compares

When compared to other turbocharged midsize trucks, the Colorado 2.7L Turbo’s 22 MPG combined rating is competitive. The Ford Ranger with its 2.3L EcoBoost engine achieves approximately 21-23 MPG combined depending on configuration, making it very similar. The GMC Canyon with the same 2.7L turbo engine matches the Colorado’s efficiency ratings. Older naturally aspirated truck engines typically achieve 18-20 MPG combined, making the turbo advantage apparent. The Colorado’s efficiency compares favorably to full-size trucks, which generally range from 18-21 MPG combined.

Tips to Maximize Efficiency

• Maintain proper tire pressure: Check tire pressure monthly and maintain the recommended PSI listed on the door jamb to reduce rolling resistance and improve fuel economy.
• Avoid unnecessary idling: Turbocharged engines consume fuel while idling. Turn off the engine if you’ll be stopped for more than a minute.
• Accelerate smoothly: Gradual acceleration reduces fuel consumption compared to hard acceleration, which forces the turbo to work harder.
• Plan efficient routes: Minimize city driving when possible and consolidate trips to reduce overall fuel consumption.
• Service regularly: Keep the engine properly tuned with clean air filters and quality oil to maintain optimal efficiency.

Frequently Asked Questions

Q: Will the 2021 Colorado 2.7L Turbo get better fuel economy than older Colorado models?
A: Yes, the 2.7L turbo engine is significantly more efficient than older naturally aspirated engines found in previous Colorado generations, offering roughly 2-3 MPG improvement in combined ratings.

Q: Does towing reduce fuel economy on this truck?
A: Yes, towing substantially decreases fuel economy. Expect reductions of 3-5 MPG or more depending on trailer weight and aerodynamics when actively towing.

Q: Can I improve the 22 MPG combined rating through modifications?
A: While driving habits and maintenance have the most impact, some drivers report modest improvements through tire upgrades and aerodynamic modifications, but results vary significantly.

The 2021 Chevrolet Colorado 2.7L Turbo 4-cylinder Crew Cab delivers solid fuel economy for a midsize turbocharged truck. With a 22 MPG combined rating, realistic annual fuel costs around $2,386, and the capability to handle various tasks, it represents a balanced choice for truck buyers seeking efficiency without sacrificing performance.
