Fuel Efficiency Expectations

When considering a heavy-duty truck like the 2025 GMC Denali HD Duramax, fuel efficiency might not be the first thing that comes to mind, but it's still an important factor for many buyers. While official fuel economy numbers for the 2025 model haven't been released yet, we can look at previous models to get an idea of what to expect. Generally, heavy-duty trucks with diesel engines are not known for their stellar fuel economy, but they do offer decent mileage considering their size and capability. In the real world, you can expect the Denali HD Duramax to achieve around 15 to 18 miles per gallon on the highway and slightly lower in the city.

The Duramax engine's advanced technology, such as its electronic fuel injection system and variable geometry turbocharger, also contributes to improved fuel economy. Compared to gasoline-powered heavy-duty trucks, the Duramax diesel engine generally offers better fuel economy, especially when towing. This is due to the diesel engine's higher torque output and more efficient combustion process. While the 2025 GMC Denali HD Duramax may not be the most fuel-efficient vehicle on the road, it offers a reasonable balance between power, capability, and fuel economy. If you're looking for a heavy-duty truck that can handle tough jobs without completely breaking the bank at the gas pump, the Denali HD Duramax is a solid choice.
