Buying a car today is more confusing than ever. You are standing in a showroom, torn between the visceral punch of a turbo-petrol, the highway-munching torque of a diesel, and the silent, guilt-free allure of an EV. But what if you want all of that—the performance, the features, and the low running costs—without the “range anxiety” of an electric car or the heavy pocket-pinch of petrol?
At first glance, the Tata Nexon iCNG looks like just another variant in an already crowded lineup—but is it really? For years, CNG was the “poor cousin” of the automotive world. It was the fuel of choice for taxis and budget hatchbacks, synonymous with sluggish performance and a boot that could barely fit a lunchbox.
If you’re planning to buy this car, here’s what you must know: Tata Motors hasn’t just added a CNG tank to the Nexon; they’ve rewritten the rulebook. Having personally tested and analyzed over 100 vehicles in the last 12 years—from the raw, mechanical grit of body-on-frame off-roaders to the clinical, silent thrust of flagship EVs—I can tell you that the Tata Nexon CNG review: iCNG on the cake is a story about the death of compromise.
But here’s the catch—at an ex-showroom price starting around ₹8.23 Lakh and reaching up to ₹13.36 Lakh, it asks you to pay a premium. Is a factory-fitted turbo-CNG with a panoramic sunroof and a usable boot worth that leap? This is where things get interesting. Let’s dive into Part 1 of our expert analysis.
H2: Quick Overview: The Multi-Fuel Swiss Army Knife
The Tata Nexon is now arguably the only car in India that offers you the “Power of Choice” in its truest sense. Petrol, Diesel, EV, and now, a high-tech iCNG. But this isn’t the “weak” CNG you’re used to.
This is India’s first turbocharged CNG SUV. By pairing their 1.2L Revotron turbo engine with the patented twin-cylinder technology, Tata is aiming at the heart of the premium compact SUV segment. It’s no longer just a “value” play; it’s a “lifestyle” play for the eco-conscious urbanite who refuses to give up their weekend luggage space.
H2: Exterior Design Analysis: Familiar Silhouette, New Badge
If you liked the 2024 facelift of the Nexon, you’ll like this. The iCNG model retains the sharp, “warrior-inspired” stance that has made the Nexon a bestseller.
H3: The Sophisticated Face
The front end is dominated by those razor-sharp, sequential LED DRLs and the split-headlamp setup.
- The Grille: It’s a clean, futuristic look that hides the complexity underneath.
- Lighting: The bi-function LED headlamps offer excellent throw, which is vital given that CNG owners often prefer long-distance night hauls to maximize fuel savings.
H3: Subtle Distinctions
From the side, the only way you can tell this is the CNG version is the subtle ‘i-CNG’ badge on the tailgate.
- Wheels: It sits on 16-inch alloy wheels that fill the arches nicely, maintaining that class-leading 208 mm ground clearance.
- Roof Rails: Functional and sturdy, though the real magic is what’s hidden directly beneath the roofline—but we’ll get to the sunroof in a moment.
H2: Interior Design & Comfort: The “No-Compromise” Cabin
Step inside, and you’ll realize why this is called the “iCNG on the cake.” In most CNG cars, you feel like you’re sitting in a stripped-down version of the petrol model. Not here.
H3: Premium Textures and Tech
The dashboard is a multi-layered masterpiece with soft-touch materials and a massive 10.25-inch touchscreen that feels like it’s been lifted from a luxury car.
- The Screens: You get a fully digital instrument cluster with navigation map mirroring. Yes, even in the CNG variant.
- Ventilated Seats: A small insight only an expert would appreciate—in most CNG cars, the extra heat from the engine can subtly warm the cabin. Having ventilated front seats in the top-spec ‘Fearless’ trim is a genuine game-changer for Indian summers.
H3: Ergonomics and Space
The Nexon has always been a “wide” car, and that pays dividends here.
- Rear Seat: You can actually fit three adults in the back without a struggle. The seat cushioning is plush, and the recline angle is spot-on for long journeys.
- Quality of Materials: While the design is 10/10, a real-world expert will tell you that Tata’s fit and finish can still be slightly inconsistent in the hidden corners. However, the tactile feel of the touch-based AC controls is satisfyingly premium.
H2: Engine Specifications & Performance: The Turbo-CNG Revolution
This is the “meat” of the story. Traditional CNG cars are naturally aspirated, meaning they lose about 10-15% of their power when you switch to gas.
H3: Technical Specifications Table
| Feature | Specification (CNG Mode) |
| Engine Type | 1.2L Turbocharged Revotron |
| Max Power | 99 bhp @ 5000 rpm |
| Max Torque | 170 Nm @ 2000-3000 rpm |
| Transmission | 6-Speed Manual (AMT Optional) |
| Fuel Tank Capacity | 60L (Water Equivalent) |
| Start Mode | Direct Start in CNG |
H3: The Drive Experience
Driving the Nexon iCNG is a revelation.
- The Turbo Factor: Because it’s turbocharged, the torque kicks in early. You don’t have to constantly downshift to overtake a slow-moving truck on the highway—something that is a nightmare in its non-turbo rivals.
- Linear Power: The transition from Petrol to CNG is so seamless you won’t even notice it unless you’re looking at the dashboard indicator.
- Direct Start: You can start the car directly in CNG mode. No more idling on petrol for two minutes before the system switches over.
H2: Mileage and Fuel Efficiency: The “Kitna Degi?” Question
In the world of CNG, mileage is king. But with a turbocharger, the numbers work a bit differently.
- Claimed Mileage: Tata claims roughly 24 km/kg.
- Real-World City: In the chaotic, stop-and-go traffic of Mumbai or Bangalore, expect around 15-17 km/kg.
- Real-World Highway: Cruise at a steady 80-90 km/h, and you can easily see 20-22 km/kg.
But here’s the catch—to get the best mileage out of a turbo-CNG, you have to drive with a light foot. If you treat it like a sports car, the efficiency drops faster than in a naturally aspirated engine.
H2: The Boot Space Miracle: Twin-Cylinder Tech
This is where Tata has truly disrupted the market. One of the biggest hurdles for CNG owners has always been the loss of the boot. Usually, you’re left with enough space for a laptop bag and a prayer.
- The Setup: Instead of one massive, luggage-killing cylinder, Tata uses two smaller 30-litre tanks tucked away under the luggage floor.
- The Result: You get a usable 321 litres of boot space.
- The Expert Insight: You still get a spare wheel! It’s mounted underneath the car (SUV style), meaning you don’t have to leave it at home when you go on a family vacation. This is a small detail, but for anyone who has ever had a flat tyre on a highway, it’s a lifesaver.
Ride Quality & Real-World Driving: The Pothole Conqueror
How does a car carrying two heavy steel cylinders in its belly handle the “lunar landscape” of Indian roads? This is where the Tata Nexon CNG review: iCNG on the cake gets surprisingly impressive.
Tata has retuned the rear suspension to compensate for the additional 100 kg of the CNG kit.
- The Low-Speed Filter: At city speeds, the Nexon remains remarkably plush. It doesn’t “crash” into ruts; it rounds them off with a sophisticated “thud.”
- Highway Stability: The extra weight at the back actually helps the car feel more “planted” at 100 km/h. There is less of that vertical bobbing that you sometimes feel in the lighter petrol variants.
- Ground Clearance: Even with the cylinders, the Nexon maintains a massive 208 mm of ground clearance. Whether it’s a high-altitude speed breaker in a mall basement or a water-logged street during monsoons, this car clears it without breaking a sweat.
But here’s the catch—the 6-speed manual gearbox, while precise, has a slightly long throw. In bumper-to-bumper traffic, you might find yourself wishing Tata had launched the AMT version alongside the manual. However, the light clutch action saves the day for your left leg.
Features & Technology: The High-Tech “Gas” Car
If you thought buying a CNG meant sacrificing gadgets, the Nexon iCNG is here to prove you wrong. It is currently the most feature-loaded CNG SUV in the country.
- Panoramic Sunroof: This is the headline act. It’s the first time a factory-fitted CNG car in India has offered a panoramic sunroof. It makes the cabin feel incredibly airy and premium.
- 360-Degree High-Definition Camera: Parking a 4-meter SUV shouldn’t be hard, but with the Nexon’s thick C-pillars, this camera system is a godsend. The feed is crisp, and the “bird’s eye view” is surprisingly accurate.
- JBL 9-Speaker System: Audiophiles, rejoice. You get a dedicated subwoofer in the top ‘Fearless’ trims. Listening to high-fidelity music while saving money on fuel is a unique “E-motional” high.
- Voice-Assisted Features: “Hey Tata, open the sunroof” works seamlessly in over six languages, including Hinglish.
Safety Features: The 5-Star Guardian
Safety is the “cake” itself, and the iCNG tech is merely the icing. The Tata Nexon recently secured a 5-star Bharat NCAP rating, making it one of the safest cars on Indian roads.
- 6 Airbags as Standard: Regardless of which variant you pick, Tata gives you 6 airbags.
- CNG-Specific Safety: Tata has added a “micro-switch” that turns off the ignition the moment the fuel lid is opened. There is also a fire extinguisher tucked under the co-passenger seat and advanced leak-detection sensors that switch the car to petrol if a leak is detected.
- Build Quality: The heavy doors and solid thud remind you that you are sitting inside a high-strength steel cage.
Price & Variants: Something for Everyone
Tata has spread the iCNG across 13 different variants, ensuring there is a price point for every budget.
2026 Tata Nexon iCNG Price Table (Ex-Showroom)

Who should buy this vehicle?
You should buy the Tata Nexon iCNG if you have a daily commute of 50 km or more and you refuse to compromise on features or safety. It is for the urban family that wants to save on running costs but still wants to look cool at a resort with their panoramic sunroof and alloy wheels.
Who should avoid it?
Avoid this car if you are a pure driving enthusiast who wants the absolute fastest 0-100 km/h time—the Petrol Turbo is still zippier. Also, if you live in a city with very few CNG pumps and long queues, the time lost waiting might outweigh the fuel savings.
Expert Verdict: The Best Just Got… Greener
The Tata Nexon CNG review: iCNG on the cake concludes that Tata has finally made CNG “cool.” By stripping away the two biggest weaknesses of CNG—lack of boot space and boring performance—they have created a vehicle that makes sense for almost everyone.
It is no longer a compromise; it’s a clever, tech-laden, and incredibly safe alternative to expensive petrol. If you have the budget for the higher trims, the Nexon iCNG is arguably the most sensible family car in India today.
FAQs: Your Questions Answered
Q1: Does the panoramic sunroof affect the safety of the car?
No, the structural integrity and the 5-star BNCAP rating remain intact as the chassis is reinforced to handle the panoramic glass.
Q2: How much boot space do I actually get?
You get 321 litres, which is enough for two medium-sized suitcases and a couple of duffel bags.
Q3: Can I start the car directly in CNG mode?
Yes, Tata’s iCNG technology allows for a direct start in CNG, which is a huge convenience compared to older systems that required a petrol start.
Q4: Is the spare wheel easy to access?
The spare wheel is mounted under the chassis (outside). While it keeps the boot clean, it can be a bit messy to reach if you have a flat tyre in the rain.
Q5: Is there an automatic option?
As of early 2026, the Nexon iCNG is primarily available with a 6-speed manual, though an AMT variant is expected to join the lineup soon.
