15 MPG combined isn’t going to win any awards, and it certainly won’t impress the casual pickup truck buyer. But for the individual who needs a 2019 GMC Canyon Cab Chassis 2WD with the 3.6L V6, that fuel economy figure is likely an acceptable cost of doing business. This isn’t a lifestyle vehicle; it’s a tool, and its thirst for gasoline is secondary to its capability. The Canyon Cab Chassis exists to be upfitted with specialized bodies, whether it’s a service bed for HVAC repair, a landscaping rig, or a small delivery box. It’s a workhorse.

City and highway performance

Breaking down that 15 MPG combined figure reveals something unusual: EPA estimates are identical at 15 MPG for both city and highway driving. Typically, trucks see a significant jump in fuel economy on the highway thanks to more consistent speeds and reduced stop-and-go traffic. The fact that the Canyon Cab Chassis doesn’t indicates a couple of things. First, its aerodynamics (especially after upfitting) are likely poor, negating any highway advantage. Second, the 3.6L V6, even with the 8-speed automatic, probably needs to work fairly hard to maintain highway speeds, especially with a load. Don’t expect to see much variation in this MPG number regardless of where you drive, particularly if the vehicle is regularly hauling equipment.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 GMC Canyon Cab Chassis 2WD 3.6L at $2,900. This calculation is based on driving 15,000 miles per year and using national average fuel prices. While your actual fuel cost will vary depending on your driving habits and local fuel prices, this figure provides a benchmark. It highlights that, even for a relatively small truck, the cost of fueling a dedicated work vehicle can be substantial. For businesses relying on multiple Canyon Cab Chassis trucks, fuel expenses can represent a significant portion of operating costs.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy for the Canyon Cab Chassis will depend heavily on how it’s used. A truck constantly loaded with heavy equipment and driven aggressively will likely fall short of 15 MPG. Conversely, a lightly loaded truck driven conservatively might achieve slightly better economy. However, given the vehicle’s inherent characteristics, its weight, aerodynamics (or lack thereof), and the engine’s power requirements, expecting significantly better fuel economy than advertised is unrealistic. This isn’t a vehicle where hypermiling techniques will make a dramatic difference. Owners should track their fuel consumption to understand their specific operating costs and identify any potential maintenance issues affecting efficiency.

How it compares

Compared to other mid-size trucks, the 2019 GMC Canyon Cab Chassis 2WD 3.6L’s fuel economy is, frankly, not great. A similarly configured Chevrolet Colorado, which shares the same engine and transmission, achieves essentially identical fuel economy. A Ford Ranger with its 2.3L EcoBoost engine, for example, can achieve around 23 MPG combined in 2WD form. Even a larger, full-size truck like the Ford F-150 with the 2.7L EcoBoost V6 can achieve 20 MPG combined in the right configuration. However, those trucks aren’t necessarily designed for the same specific upfitting purposes as the Canyon Cab Chassis. The key differentiator is the “Cab Chassis” designation, which implies a focus on customization and commercial applications rather than outright fuel efficiency. For buyers prioritizing fuel economy above all else, looking at all Gmc fuel economy data might reveal other, more economical options within the GMC lineup, or even alternative makes and models. For buyers already committed to the Canyon platform, examining CANYON MPG across all years might highlight minor fuel economy improvements in other model years.

Tips to maximize efficiency

Regular maintenance is critical for maintaining optimal fuel economy. Ensure the engine is properly tuned, the air filter is clean, and the tires are correctly inflated. A poorly maintained engine will burn more fuel, and low tire pressure increases rolling resistance. Don’t neglect scheduled service intervals, as preventative maintenance can catch small problems before they become major fuel-efficiency killers.

Avoid unnecessary idling. The 3.6L V6 consumes fuel even when the vehicle is stationary. If you’re going to be stopped for more than a minute or two, turn off the engine. This is especially important in commercial applications where vehicles often sit idling for extended periods. While seemingly small, the cumulative effect of excessive idling can significantly impact fuel consumption.

Drive smoothly and avoid aggressive acceleration and braking. The harder the engine has to work, the more fuel it will consume. Anticipate traffic conditions and maintain a steady speed whenever possible. A smooth driving style not only improves fuel economy but also reduces wear and tear on the vehicle.

Consider the weight of your load. Overloading the Canyon Cab Chassis will significantly reduce fuel economy. Adhere to the vehicle’s weight limits and distribute the load evenly to minimize stress on the engine and suspension. Reducing unnecessary weight can have a noticeable impact on fuel consumption.

Explore aftermarket accessories with caution. While some accessories, like aerodynamic bed covers, might offer a marginal improvement in fuel economy, others, like oversized tires or lift kits, will almost certainly worsen it. Carefully consider the trade-offs between aesthetics and fuel efficiency when choosing aftermarket modifications. Focus on accessories that enhance the vehicle’s functionality without hurting its fuel economy.
