Delhi's CNG network is one of the densest in India, making CNG taxis the most economical choice for city-based cab drivers. With running costs as low as ₹1.5 per km versus ₹4–5 for petrol, a CNG taxi under ₹3 lakh can recover its cost within 12–18 months of regular use.

What to Check Before Buying a Used CNG Taxi in Delhi
Buying a used CNG taxi requires a few extra checks beyond a regular car inspection. CNG kits wear out and need certification. Always verify the following:
- CNG kit certification: The AIS-137 certified CNG kit must have a valid test report. Uncertified kits fail Delhi's pollution checks.
- Cylinder hydrostatic test date: CNG cylinders must be pressure-tested every 3 years. Check the sticker on the cylinder.
- Gas leakage check: Ask a mechanic to test for leaks at the regulator, pipes, and filler valve.
- RC and fitness certificate: Confirm the vehicle is registered as a commercial vehicle and has a valid fitness certificate from a Delhi RTO.
- Commercial permit: Check the all-India tourist permit or Delhi contract carriage permit depending on your use case.
