Owners of the 2021 Chevrolet Colorado 4WD with the 3.6L V6 engine get 19 MPG combined. It’s not designed to sip fuel. This Colorado configuration is for buyers who prioritize capability and strong performance over outright efficiency. They understand that confident towing, decent off-road ability, and the practicality of a pickup bed mean a thirstier fuel tank.

City and highway performance

The EPA estimates for the 2021 Colorado 4WD with the 3.6L V6 are 17 MPG in the city and 24 MPG on the highway. The lower city figure shows the engine working harder during stop-and-go traffic, frequent acceleration, and idling, conditions the 3.6L naturally uses more fuel in. The highway number, while better, shows that this configuration isn’t designed for hypermiling. Even at a steady cruise, the four-wheel-drive system and the vehicle’s weight contribute to higher fuel consumption than a smaller, more aerodynamic vehicle.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Chevrolet Colorado 4WD 3.6L V6 at $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Individual spending will vary based on driving habits and local fuel costs. However, the $2,300 estimate provides a standardized benchmark for comparing the Colorado’s fuel expenses to other vehicles in its class, and it should be factored into the total cost of ownership.

Real-world expectations

EPA estimates provide a useful reference, but real-world fuel economy often changes. Factors like driving style, terrain, and load weight have a significant impact.

Colorado owners who frequently tow trailers, haul heavy cargo, or tackle off-road trails can expect to see fuel economy below the EPA estimates, possibly even dipping into the low teens. Conversely, drivers with a gentle foot who mostly use the Colorado for commuting and errands might achieve figures closer to the EPA combined rating, but surpassing it is unlikely.

How it compares

The 2021 Colorado’s fuel economy compares to its competitors in expected ways. A comparable 4×4 V6 Toyota Tacoma, for example, nets an EPA-estimated 18 MPG combined. The Nissan Frontier, with its older V6, achieves similar figures. The Ford Ranger, particularly with the turbocharged 2.3L EcoBoost engine in a 4×4 configuration, manages slightly better fuel economy, often reaching around 20-22 MPG combined.

Buyers cross-shopping these trucks understand this difference, but for many, the Colorado’s specific blend of V6 power, 8-speed transmission refinement, and Chevrolet’s interior design is worth the fuel economy penalty. If fuel economy is a higher priority, exploring the 2WD versions of these trucks or considering the Colorado’s own 2.8L Duramax diesel engine, which can achieve significantly better MPG, would be beneficial.

Tips to maximize efficiency

Avoid aggressive acceleration. The 3.6L V6 is responsive, but each sudden burst of speed burns unnecessary fuel. Gradual acceleration, especially from a standstill, allows the engine to operate more efficiently and helps maintain a steady fuel flow.

Monitor tire pressure consistently. Underinflated tires increase rolling resistance, which forces the engine to work harder. Maintaining the recommended tire pressure, found on the driver’s side doorjamb, is a simple way to improve fuel economy.

Minimize idling. Letting the engine idle for extended periods, whether waiting in a parking lot or warming it up on a cold morning, consumes fuel without moving the vehicle. If you anticipate a wait longer than a minute, it’s generally more efficient to turn off the engine and restart it when you’re ready to go.

Lighten your load. Remove any unnecessary cargo from the bed or cab. Extra weight increases the engine’s workload and reduces fuel economy. The Colorado is capable, but carrying extra gear daily impacts fuel efficiency unnecessarily.

Consider a tune-up. A properly maintained engine operates more efficiently. Regular maintenance, including air filter replacements and spark plug inspections, ensures the engine runs at its peak performance. This is important for those who subject their Colorado to demanding conditions.
