The Maruti Suzuki Dzire is the most widely used CNG taxi in Delhi — more than 60,000 Dzires operate as commercial taxis across Delhi NCR. The CNG variant's claimed mileage of 31.12 km/kg is the ARAI test figure. Real-world taxi use in Delhi is significantly different. Here is the actual data from Delhi Dzire taxi operators in 2026.
Real-World Dzire CNG Mileage — Delhi 2026
- City traffic (stop-and-go, AC on): 22–25 km/kg
- City traffic (AC off): 26–29 km/kg
- Highway/outstation (NH roads, AC on): 28–32 km/kg
- Mixed city + highway (typical Ola/Uber pattern): 24–27 km/kg
- Old CNG kit (pre-2019 models, aftermarket kit): 18–22 km/kg
- Factory CNG (2020+ models): 24–28 km/kg in city use
What Affects Dzire CNG Mileage in Delhi Taxi Use
- CNG pressure: Low cylinder pressure (below 150 bar) drops mileage by 15–20% — fill regularly
- AC usage: Delhi summers demand full AC — this cuts CNG mileage by 3–5 km/kg
- Traffic conditions: Connaught Place–Noida corridor sees worst mileage due to frequent stops
- Vehicle age: Dzires above 1.5 lakh km show 10–15% lower CNG efficiency due to engine wear
- CNG kit type: Factory sequential injection (2020+) is 15% more efficient than aftermarket single-point kits
- Tyre pressure: Under-inflated tyres reduce mileage by 5–8%
Running Cost Calculation — Dzire CNG Taxi Delhi 2026
At current Delhi CNG price of ₹76.59/kg and real-world mileage of 24 km/kg, Dzire runs at ₹3.19 per km. For 150 km/day, daily CNG cost is ₹480. Monthly fuel cost (26 working days): ₹12,480. This compares to ₹22,000–₹30,000 monthly fuel for a diesel Innova Crysta — making the Dzire CNG the most economical taxi in Delhi for per-km operations.
How to Improve Dzire CNG Mileage in Delhi
- Service the CNG kit every 20,000 km — clean injectors and adjust pressure settings
- Check and replace CNG filter every 15,000 km
- Maintain correct tyre pressure (32 PSI front, 35 PSI rear)
- Avoid fast acceleration from traffic lights — CNG engines respond better to smooth driving
- Service the Dzire engine every 10,000 km with Maruti-authorized oil and filters
