Tata Altroz iCNG Review: The Smartest and Safest CNG Hatchback – Twin Cylinders, Premium Features, and 5-Star Safety!
Introduction: The Tata Altroz iCNG marks a significant milestone in the Indian automotive landscape, boldly stepping forward as the country’s first premium hatchback to incorporate an ingenious twin-cylinder CNG layout. This innovative design addresses the long-standing compromise of reduced boot space in CNG vehicles, making the Altroz iCNG a truly practical and desirable option for eco-conscious urban and suburban users.
Priced from an ex-showroom ₹ 11,09,000*, the Tata Altroz iCNG is built on Tata’s highly acclaimed ALFA (Agile Light Flexible Advanced) architecture, renowned for its rigidity and safety. This iCNG variant offers a compelling blend of balanced performance, impressive cabin space, and outstanding fuel economy, making it an intelligent choice for families and individuals prioritizing both efficiency and safety in their daily commutes and beyond.
Key Features: Innovation, Safety, and Practicality at its Core
The Tata Altroz iCNG is packed with pioneering features that set it apart in the CNG segment.
- 1.2L iCNG Engine with Dual Cylinder Technology: The heart of the Altroz iCNG is its 1.2L Revotron iCNG engine, optimized for dual-fuel operation. The revolutionary twin-cylinder CNG layout places two smaller CNG tanks (each 30L water capacity) under the boot floor, leaving a usable 210L boot space – a best-in-class figure for CNG hatchbacks and a significant advantage over traditional single-cylinder CNG setups. The engine produces 73.5 PS @ 6000 rpm and 103 Nm of torque @ 3500 rpm on CNG.
- Dual Fuel System with Auto Switch: The car seamlessly switches between Petrol and CNG, and can even start directly in CNG mode, offering unparalleled convenience. It comes with a 37L petrol tank and a combined 60L water capacity CNG tank (approx. 10-12kg CNG), ensuring excellent range.
- Enhanced Safety Protocols: Tata has integrated multiple layers of safety specific to the CNG system, including a Micro-Switch for Safe Refueling (engine automatically turns off when the fuel lid is opened), an advanced Leak Detection System, Thermal Protection to prevent overheating, and a Fire Protection System to mitigate risks.
- 5-Star Global NCAP Safety Rating: Building on the Altroz’s strong foundation, the iCNG variant carries forward the segment-leading 5-star safety rating from Global NCAP for adult occupant protection, making it one of the safest cars on Indian roads.
- Premium Interior and Infotainment: The Altroz is known for its premium cabin, which continues in the iCNG variant. It features a sophisticated infotainment system (details vary by variant, but higher trims offer touchscreen, connected car tech, etc.) and a well-appointed interior.
- 16” Alloy Wheels: The provision of 16-inch alloy wheels (in higher variants) not only enhances the vehicle’s aesthetic appeal but also contributes to better road presence and handling.
- Class-leading 210L Boot Space (in CNG mode): This is a game-changer for CNG cars, making the Altroz iCNG genuinely practical for family use and luggage, a stark contrast to other CNG hatchbacks.

The Driving Experience: Pros and Cons for the Eco-Conscious Urban User
The Tata Altroz iCNG offers a compelling blend of efficiency, space, and safety, but it’s essential to consider all aspects.
✔️ Pros: Why the Tata Altroz iCNG is a Smart Choice
- Innovative Twin-Cylinder CNG Layout: This is the biggest differentiator. By splitting the CNG tanks, it frees up a significant 210 liters of usable boot space, making it vastly more practical than other CNG hatchbacks.
- Best-in-Class Safety with 5-Star Rating: Carries forward the Altroz’s GNCAP 5-star safety rating, making it the safest CNG car available in India, offering unmatched peace of mind.
- Seamless Switching & Direct CNG Start: The ability to start directly in CNG mode and the smooth automatic transition between petrol and CNG modes enhance convenience and user experience.
- Affordable Running Cost: CNG offers significantly lower running costs per kilometer compared to petrol, making it highly economical for daily commutes.
- Premium Interior and Infotainment: The Altroz’s well-designed, feature-rich cabin and advanced infotainment system (in higher variants) provide a comfortable and modern driving environment.
- Comprehensive CNG Safety Features: Tata has equipped the iCNG system with multiple layers of safety, including leak detection, thermal protection, fire protection, and a micro-switch for safe refueling.
- Good Ground Clearance (165mm): Adequate for navigating typical Indian road conditions.
- Runs on Both CNG and Petrol: Offers fuel flexibility, ensuring you’re never stranded even if CNG is unavailable.
❌ Cons: Points for Consideration
- Slight Drop in Power Compared to Petrol: While the iCNG engine is refined, there is a noticeable drop in power (73.5 PS vs 87.8 PS for petrol) and torque (103 Nm vs 115 Nm) when running on CNG, which can affect performance during quick overtakes or on inclines.
- Lower Boot Space Than Petrol/Diesel Variants: While best-in-class for CNG cars, the 210L boot space is still less than the 345L offered by the petrol/diesel Altroz, which might be a factor for users who frequently carry large luggage.
- No Automatic Transmission Option: Currently, the Altroz iCNG is only available with a 5-speed manual transmission. The absence of an AMT or other automatic option can be a drawback for city commuters seeking clutch-free driving.
- Slight Performance Lag on Full Load: When fully loaded with passengers and luggage, the power deficit on CNG might become more apparent, leading to a noticeable performance lag.
- Higher Upfront Cost Than Tiago iCNG: While the Altroz iCNG is premium, its starting price is considerably higher than Tata’s own Tiago iCNG, which might deter budget-focused CNG buyers.
- No Cruise Control: A feature that would enhance comfort on long highway stretches, but is absent in the iCNG variants.
Final Verdict: The Smartest, Safest, and Most Practical CNG Car for Modern India
The Tata Altroz iCNG is not just another CNG car; it’s a revolutionary offering that truly redefines the segment. Its innovative twin-cylinder CNG layout addresses the long-standing boot space compromise, making it the most practical CNG hatchback in India for families and everyday utility. Coupled with Tata’s legendary 5-star Global NCAP safety rating, it also stands as the undisputed safest CNG car on the market, offering unparalleled peace of mind.
While there’s a slight drop in performance compared to the petrol variant and no automatic transmission option, the Altroz iCNG compensates with exceptionally low running costs, seamless dual-fuel operation, and a host of advanced CNG safety features. Its premium interior, comfortable ride, and smart design further cement its position as a top-tier choice.
For eco-conscious urban and suburban family users who are looking for a fuel-efficient hatchback that delivers on safety, practicality, and premium features without compromise on usable boot space, the Tata Altroz iCNG is a standout and highly recommended choice. It’s truly the smartest and safest CNG car in India today.
