21 MPG combined isn’t going to set any fuel-sipping records, but for the 2018 Chevrolet Colorado 4WD with the 2.5L four-cylinder, it’s an acceptable compromise for those who need a capable truck without the bulk of a full-size pickup. This isn’t a truck for everyone; it’s a deliberate choice made by buyers who value maneuverability, practicality, and a lower price over outright power and towing capacity.

City and highway performance

The EPA estimates the 2018 Colorado 4WD 2.5L at 19 MPG in the city and 24 MPG on the highway. That city figure reflects the inherent inefficiency of stop-and-go driving, which is made worse by the added weight and drivetrain friction of four-wheel drive. The highway number, while better, still lags behind many modern SUVs and crossovers. This is largely due to the Colorado’s truck-like aerodynamics and the relatively small engine working harder at higher speeds to overcome wind resistance. The six-speed automatic transmission, while generally smooth, isn’t geared for maximum fuel efficiency in this configuration, favoring acceleration and low-end torque instead. The Colorado buyer understands this tradeoff; they’re less concerned with squeezing every last mile from a gallon and more interested in the truck’s ability to handle light-duty tasks, inclement weather, and the occasional off-road excursion.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Chevrolet Colorado 4WD 2.5L at $2,100. This figure is based on driving 15,000 miles per year, using national averages for fuel prices. It’s a useful benchmark for comparing the running costs of different vehicles, but it’s critical to remember that your actual fuel expenses will vary depending on your driving habits, location, and current gas prices. Aggressive acceleration, frequent short trips, and prolonged idling will all significantly reduce your real-world fuel economy and inflate that $2,100 figure. Conversely, a smooth driving style, consistent highway cruising, and diligent maintenance can potentially lower your operating costs. Fuel prices fluctuate; a significant increase in gas prices would naturally increase your yearly fuel expenditure.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy can differ significantly. Colorado owners report a range of MPG figures, often falling slightly below the EPA estimates, especially in mixed driving conditions. Several factors, such as tire pressure, vehicle load, and even the use of accessories like roof racks can negatively impact fuel efficiency. Consistent use of the four-wheel-drive system will also noticeably decrease MPG. Buyers should realistically expect to see figures closer to 18-22 MPG in combined driving, possibly dipping lower with heavy loads or frequent off-road use. Remember, the Colorado is a truck, and should be driven accordingly to maintain realistic expectations.

How it compares

Compared to its competitors, the 2018 Colorado 4WD 2.5L’s fuel economy is relatively unremarkable. The Toyota Tacoma, in its 4×4 SR trim with the 2.7L four-cylinder, achieves a similar 20 MPG combined. The Nissan Frontier, with its 4.0L V6 and four-wheel drive, delivers a lower 17 MPG combined. These figures suggest similar performance, but the differences matter to the conscientious buyer. Someone choosing the Colorado over the Frontier likely prioritizes efficiency, even if only marginally. Someone considering the Tacoma may find the Colorado offers a better balance of fuel economy, price, and features. Examining all Chevrolet fuel economy data can help you make a confident decision.

Tips to maximize efficiency

Tire pressure is important. Ensure your tires are inflated to the recommended pressure listed on the doorjamb sticker. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, especially during temperature changes.

Avoid aggressive driving habits. Rapid acceleration and hard braking consume significantly more fuel than smooth, gradual changes in speed. Anticipate traffic flow and maintain a consistent speed whenever possible. Consider using cruise control on the highway to maintain a steady pace and optimize fuel efficiency.

Reduce unnecessary weight. Carrying extra cargo or equipment adds weight to the vehicle, requiring the engine to exert more effort to move it. Remove any unused items from the truck bed or cab to minimize weight and improve fuel economy. Think carefully about what needs to be taken on each journey.

Minimize idling. Avoid letting the engine idle for extended periods, as it consumes fuel without moving the vehicle. If you anticipate being stopped for more than a minute or two, turn off the engine. Restarting the engine consumes less fuel than idling for a prolonged time.
