22 MPG combined is the figure associated with the 2021 Chevrolet Colorado 4WD 2.8L diesel. While this might not excite those comparing it to crossovers, it’s often acceptable to the loyal owners who value this truck. The Colorado diesel isn’t bought for fuel efficiency; it’s bought for its unique blend of capability, size, and relatively decent towing capacity in a small package. For many, 22 MPG is an acceptable tradeoff for the diesel’s inherent advantages when hauling or navigating challenging terrain.

City and highway performance

The EPA’s individual ratings are 19 MPG in the city and 28 MPG on the highway. The city figure reflects the diesel’s slightly sluggish response at low speeds, a trait common to many diesels due to turbo lag. Frequent stop-and-go traffic increases fuel consumption. The highway number is more appealing, showcasing the diesel’s strength: effortless cruising. At highway speeds, the engine barely works hard, allowing it to maintain its advertised efficiency. These numbers result from the engine’s design; it’s optimized for low-end torque, not outright fuel efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Chevrolet Colorado 4WD 2.8L diesel at $2,550. This calculation is based on driving 15,000 miles per year, with a fuel price reflecting a national average. Individual fuel costs will change based on local fuel prices and driving habits. Drivers who primarily take short trips or frequently tow will likely exceed this estimate. Those who spend a significant amount of time on the highway might find their actual annual cost to be somewhat lower. Remember that it’s an average, your mileage may vary. Before deciding, research all Chevrolet fuel economy data.

Real-world expectations

The EPA’s numbers are a good starting point, but real-world experiences often differ. Owners report a wide range of fuel economy figures, largely dependent on driving style, load, and terrain. Those who regularly tow heavy loads will see a significant drop in MPG, often below 20 MPG. Off-road driving, with its lower speeds and increased engine load, also hurts fuel economy. Drivers who prioritize fuel efficiency and avoid aggressive driving habits can report numbers close to, or even slightly exceeding, the EPA’s estimates. Understanding the diesel’s strengths and weaknesses and adjusting driving habits is key.

How it compares

The Colorado’s fuel economy is unique within the mid-size truck segment. A similarly equipped Toyota Tacoma 4×4 with its V6 engine typically manages around 18-20 MPG combined. The Nissan Frontier, with its older engine design, often struggles to achieve even that. The Jeep Gladiator generally scores around 19-22 MPG combined with its gas V6 option, while offering similar off-road ability. The key difference is the diesel engine option; none of these offer a torquey diesel engine other than the Gladiator (which returned 24 MPG combined in the EcoDiesel configuration). The Colorado diesel’s 22 MPG then becomes more acceptable when considering its unique capabilities. Buyers choose this engine specifically for its low-end torque and towing advantages offered in a smaller, easier to maneuver package. If fuel economy is the primary concern, other mid-size trucks or even crossovers might be a better fit, but they won’t deliver the same towing experience.

Tips to maximize efficiency

Minimize idling time. Diesel engines, including the Colorado’s 2.8L, are less efficient when idling. If you anticipate stopping for more than a minute, turn off the engine. Restarting it consumes less fuel than letting it idle.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side door.

Avoid aggressive driving. Rapid acceleration and hard braking hurt fuel economy. Drive smoothly and anticipate traffic flow to minimize unnecessary speed changes. Let the diesel’s abundant torque do the work; there’s no need to floor the accelerator.

Reduce weight. Hauling unnecessary weight significantly impacts fuel economy. Remove any items from the bed of the truck that are not needed. A lighter vehicle requires less energy to move, resulting in better fuel efficiency.

Use cruise control on the highway. Maintaining a consistent speed on the highway helps get better fuel economy. Cruise control prevents unintended speed fluctuations, allowing the engine to operate at its most efficient level.
