Q. Ertiga CNG or Petrol which should I purchase?

Selecting between the fuel type depends on your daily running with the car. If you drive more than 50kms in a day then the CNG would be a better option for its better fuel efficiency, whereas the petrol would be a good option if the daily usage isn't that high. Moreover, the CNG model churns out 92PS and 122Nm while the 1.5-liter petrol engine produces 105PS of power and 138Nm of torque. For a better understanding of performance and driving comfort, we would suggest you to take a test ride. Follow the link and select your desired city for dealership details.
