When I was in the Navy, we had a truck that was CNG. It drove and felt the same as the gas powered one as far as power. The only limitation was the size of the tank. We had a 60 mile range on it. The tank pressure would show good, but 10 miles later would be starving for fuel. We had to keep a log of mileage at fill up and I got in one day and it was at 82 miles since fill up. The station was about 1 mile away across the base and I did not make it. When I started the truck, it kept sputtering at idle. It was very much like a propane grill. By the time the little pressure gauge showed it was a little low, it was too late to make it back to the fuel station, so we made sure it never got to that point by limiting mileage.
