As a subject matter expert in the field of alternative fuels and automotive engineering, I've spent considerable time analyzing the efficiency and cost-effectiveness of various vehicle propulsion systems. One of the most common inquiries I receive pertains to the comparative fuel efficiency of Compressed Natural Gas (CNG) vehicles versus their gasoline counterparts.
To address the question directly: Do CNG vehicles get better gas mileage? The answer is nuanced and depends on several factors, including the vehicle's engine design, the specific model, and the conditions under which it is operated.
Firstly, it's important to understand that CNG is a cleaner-burning fuel compared to gasoline. When burned, it emits fewer greenhouse gases and pollutants, making it a more environmentally friendly option. However, this doesn't necessarily translate to better gas mileage.
The energy content of natural gas is lower than that of gasoline. A gallon of gasoline contains more energy than an equivalent amount of natural gas. This is why, on a volume basis, gasoline provides more energy and thus can offer better mileage. However, the statement that "One GGE (Gallon of Gasoline Equivalent) of natural gas produces an equal amount of energy as a gallon of gasoline" is accurate. The GGE is a unit designed to compare the energy content of different fuels, and it's used to standardize the comparison between natural gas and gasoline.
When considering the cost of fuel, it's true that CNG often costs significantly less than gasoline. This can be seen in the example provided where the cost of CNG is $1.39 per GGE, which is considerably lower than the price of gasoline. This cost difference can make CNG vehicles more economical to operate, even if their mileage is not superior.
The efficiency of a CNG vehicle can also be influenced by the engine's design. Some engines are specifically optimized for CNG, which can improve their efficiency compared to engines that are not. Additionally, the weight of the CNG tanks and the space they occupy can affect the vehicle's overall performance and efficiency.
It's also worth noting that CNG vehicles may not have the same range as gasoline-powered vehicles due to the lower energy density of natural gas. This means that CNG vehicles might need to be refueled more frequently, which can be a consideration for drivers who travel long distances.
In terms of specific models, such as the 2011 CNG Tahoe mentioned, it's possible for a CNG vehicle to achieve similar mileage to its gasoline counterpart, especially if the vehicle has been designed with CNG in mind. However, this is not universally true for all CNG vehicles and should be considered on a case-by-case basis.
In conclusion, while CNG vehicles do not inherently get better gas mileage due to the lower energy content of natural gas compared to gasoline, they can offer cost savings due to the lower price of CNG and have environmental benefits due to reduced emissions. The decision to choose a CNG vehicle should be based on a comprehensive evaluation of these factors, as well as individual driving needs and preferences.

One GGE of natural gas produces an equal amount of energy as a gallon of gasoline. Therefore it gets the exact same gas mileage. However, a GGE of natural gas costs significantly less (I pay $1.39). For example, the gas mileage for my 2011 CNG Tahoe is the same as its gasoline counterpart: 21 MPG on the highway.Dec 7, 2011
