19 MPG combined is the fuel economy for the 2022 Chevrolet Colorado ZR2 4WD with the 2.8L Duramax diesel. Nobody buys this truck because they’re chasing Prius-like fuel efficiency. This is a purpose-built off-road machine designed to conquer challenging terrain, and the diesel’s relative frugality is a secondary benefit after its strong torque.

City and highway performance

The EPA estimates the ZR2 diesel at 18 MPG in the city and 22 MPG on the highway. These numbers reflect stop-and-go driving and sustained higher speeds. The city figure likely suffers from the weight of the ZR2’s off-road equipment (skid plates, rock sliders, etc.) and the inherent inefficiencies of diesel engines at low RPM. Highway fuel economy benefits from the diesel’s ability to cruise at lower engine speeds, but the ZR2’s aerodynamics, compromised by its aggressive stance and off-road tires, still hold it back.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2022 Chevrolet Colorado ZR2 diesel at $2,950. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It assumes national average fuel prices at the time of calculation. Your actual fuel cost will vary depending on your driving habits, the type of driving you do and fuel prices in your specific area. You can compare this to all Chevrolet fuel economy data to see where this specialized truck stacks up.

Real-world expectations

ZR2 diesel owners report real-world fuel economy that aligns closely with the EPA’s estimates, even a bit higher on longer highway trips. Driving the truck hard off-road, adding aftermarket accessories (roof racks, heavier bumpers), or frequently towing will significantly decrease fuel economy. Consider the cost of Diesel Exhaust Fluid (DEF), which is required for modern diesel engines to meet emissions standards. It’s a relatively minor expense, but it adds to the overall cost of ownership. People who want to understand COLORADO MPG across all years should research the gasoline options as well.

How it compares

The ZR2 diesel occupies a unique spot compared to its competitors. The Toyota Tacoma TRD Pro, equipped with the 3.5L V6, is rated at 18 MPG combined. The Ford Ranger Tremor, with its 2.3L EcoBoost, manages 20 MPG combined. The Jeep Gladiator Rubicon, with the 3.6L V6, achieves 19 MPG combined. The Ranger Tremor offers slightly better fuel economy, but none of these gasoline-powered rivals can match the ZR2 diesel’s low-end torque, an important factor for off-road enthusiasts. For buyers prioritizing off-road capability and diesel grunt over fuel efficiency, the ZR2 is a good choice. If fuel economy is a higher priority, the standard gasoline V6 Colorado is rated at 20 MPG combined in 4WD configuration.

Tips to maximize efficiency

Adopt smooth driving habits. Avoid hard accelerations and sudden braking, as these actions significantly reduce fuel economy, especially in a diesel engine. Gentle acceleration and consistent speeds are key to optimizing fuel consumption.

Maintain proper tire pressure. The ZR2’s aggressive off-road tires are prone to losing pressure, and underinflated tires increase rolling resistance. Check your tire pressure regularly and inflate them to the recommended level, found on the sticker in the driver’s side doorjamb.

Minimize idling. Diesel engines consume more fuel than gasoline engines when idling. Shut off the engine if you anticipate being stationary for more than a minute or two.

Consider your route. Planning your trips to avoid congested areas can make a noticeable difference in overall fuel economy. Highway driving is where the ZR2 diesel will perform best.

Keep up with maintenance. Regular maintenance, including oil changes and air filter replacements, can ensure that your engine is running efficiently. A properly maintained engine will deliver optimal fuel economy.
