The EPA estimates 22 MPG combined for the 2019 Chevrolet Colorado 4WD with the 2.8L Duramax diesel engine. While that sounds adequate on paper, buyers seeking this specific build of Chevy’s mid-size pickup consider it an acceptable tradeoff for strong capability and durability, not necessarily a primary selling point. This Colorado is for hauling, towing, and exploring with confidence, knowing the diesel engine will provide the torque needed for demanding tasks, not for minimizing trips to the gas station.

City and highway performance

The 2019 Colorado diesel’s fuel economy breaks down to 19 MPG in the city and a respectable 28 MPG on the highway. The city figure reflects stop-and-go driving, where the diesel’s heavier engine components and slower revving diminish efficiency compared to open roads. However, the highway figure is where this engine shines. The 28 MPG rating can be achieved during steady-state cruising, thanks to the diesel’s ability to operate efficiently at lower RPMs while delivering ample power for passing and maintaining speed on inclines. This makes it a strong choice for those who regularly undertake longer trips, especially when towing.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Chevrolet Colorado 4WD 2.8L diesel at $2,550. This figure comes from the EPA’s assumption of 15,000 miles driven per year, with a percentage split between city and highway driving, using national average fuel prices at the time of calculation. It’s a useful benchmark, but individual fuel costs will vary significantly depending on driving habits, local fuel prices, and the actual percentage of city versus highway miles driven. Buyers should consider their own typical driving patterns to get a more realistic estimate of their potential fuel expenses when comparing all Chevrolet fuel economy data, or examining the COLORADO MPG across all years.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the 2019 Colorado diesel 4WD can fluctuate based on many factors. Towing, off-roading, and aggressive driving will all negatively impact fuel efficiency. Expect to see numbers slightly lower than the EPA estimates in mixed driving conditions.

However, conscientious drivers who prioritize smooth acceleration, maintain consistent speeds, and minimize idling can often meet or even exceed the highway MPG rating. The key is understanding how driving style affects fuel consumption with a diesel engine and adapting accordingly.

How it compares

Comparing the 2019 Colorado diesel’s fuel economy to its competitors provides valuable context. The Toyota Tacoma, with its 3.5L V6, typically achieves around 18 MPG combined in its 4×4 configurations, making the Colorado’s 22 MPG a notable advantage. The Nissan Frontier, with its older 4.0L V6, struggles to reach even 17 MPG combined in 4×4 models.

One close competitor is the Honda Ridgeline, generally achieving 21 MPG combined thanks to its unibody construction and 3.5-liter V6. Even though they are similar, the Ridgeline does not provide the diesel towing capabilities that are important to many Colorado diesel buyers. These comparisons highlight that while the Colorado diesel isn’t the most fuel-efficient mid-size truck overall, it offers a satisfying balance of fuel economy and capability compared to many gasoline-powered rivals.

The Jeep Gladiator fares worse, generally coming in around 19 MPG combined; however, its appeal to off-road enthusiasts is undeniable. Buyers need to weigh fuel economy against their specific needs when shopping the midsize truck segment.

Tips to maximize efficiency

Minimize idling time. Diesel engines consume a surprising amount of fuel when idling, so avoid unnecessary idling whenever possible. If you’re stopped for more than a minute or two, shut off the engine.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, leading to decreased fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, which can be found on the sticker inside your driver’s side door.

Drive smoothly and avoid aggressive acceleration. Diesel engines are most efficient when driven smoothly and at a consistent speed. Avoid sudden acceleration and braking, which wastes fuel and increases wear and tear on the engine.

Keep up with scheduled maintenance. Regular maintenance, including oil changes, air filter replacements, and fuel filter replacements, ensures that your engine is running at peak efficiency. Consult your owner’s manual for the recommended maintenance schedule.

Consider using a fuel additive designed for diesels. Some fuel additives can help improve fuel economy by cleaning fuel injectors and increasing the cetane rating of the fuel. Research and choose a reputable additive specifically formulated for diesel engines.
