21 MPG combined is a respectable number for the 2021 Chevrolet Colorado 4WD equipped with the 2.5L 4-cylinder engine. It won’t win any hypermiling awards, but understand what this truck *is*: a body-on-frame, four-wheel-drive pickup. This specific Colorado configuration caters to a buyer prioritizing ruggedness and utility over outright fuel efficiency. This is the work truck, the trim aimed at those who need basic, dependable capability without all the frills, and who are willing to accept relatively modest fuel economy as the cost of doing business.

City and highway performance

The EPA estimates place the city fuel economy of this Colorado at 19 MPG, while the highway figure is a more palatable 24 MPG. That spread reveals something important: this truck does better on the open road than it does navigating stop-and-go traffic. The 2.5L engine, while adequate, needs to work harder to get the truck moving from a standstill, especially with four-wheel drive engaged (even if it’s an on-demand system). Once up to speed on the highway, the engine settles into a more efficient cruising rhythm, aided by the six-speed automatic transmission. Drivers will find that maintaining a steady speed, avoiding excessive acceleration, and limiting city driving can significantly improve their average fuel consumption.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Chevrolet Colorado 4WD 2.5L at $2,100. This figure is based on driving 15,000 miles per year, using the EPA’s combined MPG rating, and assuming the national average price for regular gasoline. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and local gas prices. If you primarily use your truck for short trips around town, expect to spend more. Conversely, if you rack up mostly highway miles, your fuel bill might be lower. It’s worth comparing this figure to similar trucks to understand the long-term cost of ownership.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy often differs. Factors like driving style, terrain, weather conditions, and cargo weight can all impact the MPG you actually achieve. Aggressive driving, frequent hard acceleration, and hauling heavy loads will undoubtedly decrease fuel economy. Off-road driving, even on maintained dirt roads, will also negatively affect your MPG. Many owners report that achieving the EPA’s 24 MPG highway figure requires conscious effort and a light foot on the accelerator. The 19 MPG city figure, however, is closer to what drivers typically experience.

How it compares

When considering fuel economy, it’s critical to examine how the 2021 Chevrolet Colorado 4WD 2.5L compares against its competitors. The Toyota Tacoma SR 4×4 with its base 2.7L four-cylinder engine achieves an EPA-estimated 20 MPG combined, 18 MPG in the city, and 22 MPG on the highway. The Nissan Frontier S 4×4, equipped with its 3.8L V6 engine, is rated at 17 MPG combined. These comparisons show that this Colorado is relatively fuel-efficient *within* its specific segment and configuration. For someone who needs the functionality of a 4WD midsize pickup and isn’t willing to jump to a larger truck, the COLORADO MPG across all years isn’t drastically different, but opting for a more basic trim like this one can save you some money in the long run. Of course, one could consult all Chevrolet fuel economy data to determine the complete picture for the brand.

Tips to maximize efficiency

Tire pressure plays an important role in fuel economy. Ensure your tires are properly inflated to the recommended pressure (found on the door jamb sticker). Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Regular tire pressure checks are a simple yet effective way to maintain optimal fuel efficiency for your Colorado.

Minimize idling. The 2.5L engine consumes fuel even when the vehicle is stationary with the engine running. Avoid excessive idling, especially during cold weather warm-ups. Turn off the engine if you anticipate being stopped for more than a minute or two. This practice can lead to noticeable fuel savings over time.

Lighten your load. The heavier the vehicle, the more fuel it consumes. Remove any unnecessary items from the truck bed or cabin. Tools, equipment, or other items carried “just in case” add extra weight and negatively impact fuel economy. This is especially true in the Colorado since the work-truck trim is often loaded with tools.

Drive smoothly and anticipate traffic. Avoid aggressive acceleration and hard braking. These driving habits waste fuel. Maintain a consistent speed and anticipate traffic flow to avoid unnecessary stops and starts. A smoother, more controlled driving style translates to better fuel economy.

Consider using cruise control on the highway. Cruise control helps maintain a constant speed, which can improve fuel efficiency on long stretches of highway driving. By avoiding fluctuations in speed, the engine operates more efficiently. Just remember to disengage cruise control in heavy traffic or inclement weather.
