Boot Space Impact
The CNG tank sits in the boot, reducing usable luggage space. Alto K10 petrol has 214L boot — CNG reduces it to approximately 150-160 litres. This means you can still fit a medium suitcase or 2-3 grocery bags, but long-trip luggage for 4 people will be challenging. The rear seats do NOT fold flat in CNG variants.
