21 MPG combined is the number to remember for the 2015 Chevrolet Colorado 2WD with the 3.6L V6. Some might consider it disappointing, but it’s a pragmatic acceptance for buyers who need a truck that’s smaller and more maneuverable than a full-size, yet still capable of hauling and towing. This isn’t a truck bought for hypermiling; it’s for those who regularly visit the home improvement store, tow a small boat, or simply prefer the upright seating position and rugged image of a pickup.

City and highway performance

The EPA estimates 18 MPG in the city and 25 MPG on the highway for this Colorado configuration. The difference between city and highway figures illustrates a typical characteristic of trucks: city driving, with its stop-and-go nature, taxes fuel economy more severely. The Colorado’s 3.6L V6, while reliable and offering ample power for most tasks, needs to work harder in urban environments. On the open road, the engine settles into a more efficient rhythm, allowing drivers to approach that 25 MPG estimate, especially when maintaining consistent speeds and avoiding aggressive acceleration. However, factors like prevailing winds, elevation changes, and even tire pressure can subtly alter these numbers, so driver awareness is vital.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,100 for the 2015 Chevrolet Colorado 2WD 3.6L V6. This figure is calculated based on driving 15,000 miles per year, with an assumed fuel price that reflects the national average. Naturally, this is a benchmark and individual expenses will vary, as fuel prices regularly fluctuate across regions and over time. Drivers who cover fewer miles annually will spend considerably less, while those exceeding the 15,000-mile mark will see their fuel costs escalate proportionally, especially if those miles are primarily in urban stop-and-go traffic.

Real-world expectations

While the EPA figures provide a standardized baseline, real-world MPG often differs. Payload, towing, driving style, and even environmental conditions significantly impact fuel consumption. A Colorado regularly loaded with tools and equipment will likely see a lower average than one used primarily for commuting. Aggressive acceleration and frequent hard braking will also diminish fuel economy. Conversely, a conscientious driver who anticipates traffic flow and maintains consistent speeds can often achieve figures closer to, or even slightly exceeding, the EPA estimates. Therefore, it’s beneficial to view the 21 MPG combined as a realistic target, rather than a guaranteed outcome.

How it compares

The 2015 Colorado’s fuel economy sits within a competitive range for mid-size trucks of its era, but comparisons are crucial. The Toyota Tacoma, particularly the 2WD models with the 2.7L four-cylinder, often delivered slightly better combined MPG figures, hovering around 22 MPG, though with less horsepower. The Nissan Frontier, another key competitor, typically mirrored the COLORADO MPG across all years with its V6 engine, offering a similar blend of capability and fuel consumption. The Honda Ridgeline, although technically a unibody truck, provided more car-like handling and typically offered slightly better fuel economy than the Colorado, approaching 24 MPG combined in its 2WD configurations, at the expense of some traditional truck capabilities. For buyers prioritizing fuel economy above all else, these alternatives represented viable options, each with its own compromises.

Tips to maximize efficiency

Regular maintenance is important. Ensure your Colorado’s tires are properly inflated to the pressure recommended on the door jamb sticker. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Similarly, keeping up with oil changes and air filter replacements ensures the engine operates at peak efficiency.

Drive smoothly and avoid aggressive acceleration. The Colorado’s 3.6L V6 responds well to gentle throttle inputs. Anticipate traffic flow and maintain a steady speed whenever possible. Hard acceleration and braking waste fuel unnecessarily and create more wear on the brakes and tires.

Minimize unnecessary weight. Remove any items from the bed or cab that aren’t essential. Extra weight increases the load on the engine and reduces fuel economy. A few extra tools or bags of sand might not seem like much individually, but their cumulative effect can impact your MPG.

Consider using cruise control on the highway. This helps maintain a consistent speed and avoids fluctuations in throttle position, contributing to better fuel efficiency. However, be mindful of road conditions and traffic, and disengage cruise control when necessary for safety.

Plan your trips efficiently. Combine errands into a single trip to minimize cold starts, which consume more fuel. Consider routes that avoid congested areas and stop-and-go traffic. A little planning can save you time and money at the pump. For all Chevrolet fuel economy data, consider the tips here and elsewhere.
