19 MPG combined isn’t going to win any awards, but for the 2019 Chevrolet Colorado ZR2 4WD 2.8L diesel, it’s the price of admission to a world of off-road capability rarely found outside of purpose-built machines. It’s a tool, a toy, and a statement all rolled into one very capable mid-size truck. Its fuel economy is secondary to its ability to conquer trails, ford streams, and generally laugh in the face of obstacles that would leave lesser vehicles stranded.

City and highway performance

The EPA estimates of 18 MPG in the city and 22 MPG on the highway reflect the Colorado ZR2’s purposeful design. The diesel engine, while offering impressive torque for off-roading and towing, isn’t optimized for outright efficiency. The shorter gearing (necessitated by the off-road tires and electronically locking differentials) and added weight contribute to these numbers. The city MPG suffers from frequent stop-and-go driving and the increased rolling resistance of the aggressive tires.

The highway MPG is slightly better, but the ZR2’s aerodynamic profile, compromised by its lifted suspension and off-road accoutrements, keeps it from achieving truly impressive highway economy. These owners generally aren’t as concerned with squeezing every last mile from a gallon, but want to check on all Chevrolet fuel economy data.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,950 for the 2019 Chevrolet Colorado ZR2 4WD 2.8L diesel. This figure is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, using national average fuel prices. It’s a useful benchmark for comparing against other vehicles, but keep in mind that individual driving habits and local fuel prices can significantly impact your actual expenses.

Some drivers who use the ZR2 primarily for shorter trips and off-roading might see a higher annual cost, while those who mostly drive on the highway could potentially see savings.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy can vary significantly based on how the Colorado ZR2 is used. Drivers who frequently engage the four-wheel-drive system, carry heavy loads, or tackle challenging terrain will undoubtedly see lower numbers.

Similarly, those who have modified their ZR2 with accessories like roof racks, larger tires, or heavier bumpers can expect a decrease in fuel efficiency. It’s important to consider your personal driving style and usage patterns when estimating your own fuel costs.

How it compares

In the realm of off-road-focused midsize trucks, the Colorado ZR2’s fuel economy sits in a competitive, but not class-leading, position. The Toyota Tacoma TRD Pro, with its gasoline V6, typically achieves around 19 MPG combined, similar to the ZR2. The Ford Ranger Raptor (not available in the US for the 2019 model year, but highly relevant to the discussion) with its gasoline engine, would likely have even lower fuel economy. Jeep Gladiator Rubicon models hover around 19 MPG combined as well. The ZR2’s diesel engine does offer a potential advantage in towing fuel economy, but that isn’t represented in the EPA’s city/highway cycle.

The tradeoffs are familiar to these buyers, and the information across COLORADO MPG across all years, plus similar trucks, is freely available.

Tips to maximize efficiency

Proper tire inflation is critical, especially with the ZR2’s off-road tires. Run them at the recommended pressure listed on the door jamb sticker for optimal rolling resistance when not actively off-roading. Even a few PSI can impact fuel economy, and proper inflation will also extend tire life.

Avoid aggressive driving habits. The diesel engine provides ample torque at low RPMs, so there’s no need to constantly accelerate hard. Smooth and steady acceleration will significantly improve fuel economy, especially in city driving where you’ll be able to make more use of the truck’s engine braking.

Minimize unnecessary weight. The ZR2 is already a heavy vehicle, so avoid carrying around items that you don’t need. Remove any aftermarket accessories that aren’t essential, such as bed racks or spare fuel cans, when not in use.

Schedule regular maintenance. A properly maintained engine is an efficient engine. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and fuel filter replacements to ensure optimal performance and fuel economy from the 2.8L diesel.

Consider speed limits on the highway, understanding that optimal efficiency is typically found in the 55-65 mph range. Exceeding this range forces the ZR2 to cut through the air and can have a big impact on fuel economy.
