Maruti suzuki Ertiga CNG variant

The Ertiga is fitted with a 60 kg water equivalent CNG tank, the segment norm, which should accommodate 8 to 10 kgs of gas per tank up. Being factory fitted, it's well-integrated too. You fill the tank through the nozzle in the fuel filler cap and there are twin fuel gauges in the instrument cluster. You also get a useful graph in the MID that shows you your fuel usage ratio between petrol and CNG. As with most CNG cars, you miss out on consumption and range data.
