I have a 2011 Model of i10 magna which is a company fitted CNG Model.1.2 CC engine. I have driven this car from Delhi to All over Punjab, Haryana, UP, Rajasthan. It is very convenient to drive, Easy to Maneuver, and handling.
The Best part is that it has a company Fitted Sequential CNG, it just shifts from Petrol to CNG and Back to Petrol so smoothly that unless it buzzes you will never understand it has shifted. the Drive is way comfortable. the average on CNG if filled with 9KG runs approx 145-150kms in Delhi and on Highway for around 220-230 Kms. Which is like less than Rs 2 per Kilometer. I find it less than what my bike gives. and the most easy part is the Turning Radius is very Less so it becomes easy to Park as Delhi has a majour Parking issue.
