Deep Analysis: Hyundai Grand i10 Nios CNG – The Urban Family Hatchback in 2025

Indian urban buyers are flocking to CNG cars, seeking low running costs and eco-friendliness without sacrificing modern features or comfort. The Hyundai Grand i10 Nios CNG has emerged as one of the most popular choices in 2025.

Here’s detailed information examining real-world user experiences, technical details, strengths, and minor compromises of this city hatch.

1. Engine, Power & Transmission

Engine: 1.2L Bi-Fuel Kappa (1197cc, 4-cylinder)
Power: 68 bhp (CNG mode) @ 6,000rpm
Torque: 95.2Nm @ 4,000rpm
Transmission: 5-speed manual
Drive: Front-wheel drive

The CNG engine offers smooth and city-friendly performance, with enough power for daily commutes and family outings. While the output is lower than the petrol-only version, the difference isn’t felt during city use—only at high speeds or on steep inclines will you need to plan overtakes and consider switching to petrol for a boost

2. Mileage & Real-World Efficiency

ARAI Certified Mileage: 27–27.3 km/kg
User-Reported City Mileage: 20–23 km/kg (with AC, city traffic)
Highway Mileage: 25–27 km/kg (steady runs)
CNG Tank Capacity: 60L (water-equivalent)
Petrol Tank: 37L (backup for long distance or low CNG areas)

Why It Matters:
Running costs are a huge win. With CNG, even Mumbai or Delhi commuters report full tank-to-tank costs of just ₹320–380 for 250–300km, half the cost of petrol. Real-world consensus pegs mileage at 20–23 km/kg in city traffic—a top performer in the segment, especially considering traffic and AC use

3. Comfort, Features & Practicality

Seating: Big enough for five; comfortable front seats; rear is best for 2.5 adults (typical for the segment)
Boot Space: 260L usable (CNG cylinder cuts volume compared to petrol variant)
Main Features:
- Touchscreen infotainment with Apple CarPlay/Android Auto
- Rear AC vents (rare among rivals)
- Multifunction steering wheel, power windows, remote locking
- Rear parking sensors + Camera
- ABS, 2 airbags standard; 6 airbags (top trim), ESC, and other advanced safety on higher variants
- Tilt steering, height-adjustable seat
- Tilt adjust steering, body-color ORVMs

Verdict: The Nios CNG doesn’t feel like a stripped-down eco car—it’s well-equipped, smartly packaged, and feels modern inside the cabin, something rivals (especially base trims of Tata or Maruti CNGs) can’t always claim

4. Driving Experience: City and Highway

City: Light clutch and gearbox, compact dimensions, light steering—all make it a breeze in tight traffic and jam-prone streets.
Ride Quality: Absorbs bumps and potholes well; minor vertical movement for rear passengers over big speed breakers, but stays comfortable.
Highway: Stable up to 90–100km/h; overtakes need planning due to lower CNG power—switching to petrol for full-load, hilly area, or high-speed runs is recommended

5. Comparisons & Segment Context

Rivals: Tata Tiago CNG, Maruti Swift CNG (not offered), Wagon R CNG
Advantages: Superior feature list, smoother engine, more refined cabin than Tata; more modern and premium-feeling than the Wagon R CNG.
Limitations: Boot space is tight for big families on trips (a common CNG issue); real-world highway power slightly behind petrol-only variants and top-end diesels

6. Costs, Ownership & Value

Ex-Showroom Price: ₹8.3 lakh (Sportz, July 2025) — on-road in metros is ₹9.5–10.1 lakh
Running Cost: Lowest in its class; maintenance intervals similar to petrol; CNG components covered by warranty.
Resale: High demand keeps resale strong in metro cities with good CNG infra.

7. User & Expert Opinions

Likes: Classy looks, fun city drive, unbeatable fuel savings, loaded with features, AC performance (even in CNG mode), Hyundai’s service support.
Dislikes: Boot space cut by tank, not for frequent high-speed or full-load highway use, premium over petrol model is not recovered at resale but is made up via savings at the pump

Summary Table

Concluding Thoughts

If you want the perfect blend of city practicality, running cost savings, and premium features—with the confidence of Hyundai’s network—the Grand i10 Nios CNG is one of 2025’s best mid-budget picks.
It delivers exceptional value for urban commuting and family use, with few real compromises beyond the expected boot limitation and modest highway power.
