The installation of the gas cylinder resulting in loss of boot space is one of the biggest concerns with CNG vehicles. As a compact SUV, the Nexon has already less cargo area than larger SUVs. With a CNG tank installed now, that space is going to shrink even more. The practicality of this is also questionable: what if you're a family or someone who more often than not has to carry around luggage? Can weekend bags still fit in the Nexon CNG? How do you buy daily essentials such as groceries or sports equipment? Even is how does that affect the weight distribution and handling of the car. Others say that the fuel cost savings make up for the loss of boot space (which they argue defeats the point of getting an SUV in the first place). This is the classic case of pros and cons, and different buyers will care about different things.
