CNG cars offer a lot of autonomy on the road – with even the smallest CNG tanks you can travel hundreds of kilometers. Fueling stations are already very common across Europe and therefore one is almost always nearby.
But what happens if you somehow forgot to fuel your car and have run out of CNG?
In that respect, a CNG car is just like any other car – once the fuel is out, the vehicle wouldn’t be able to run any more, however, there is an added benefit that is present on CNG cars – all of them have a petrol tank too that is used to turn the engine on (after which, the car switched automatically to CNG) but it doubles as a backup to CNG.
So, in the case you run out of it, use the petrol tank to get to the nearest station and fill in there.
