2. Latest Engine Tech & Improvements in 2025

Space & Packaging Innovations

Twin-CNG Cylinder Tech: Tata and Hyundai use twin-cylinder setups (two smaller tanks vs. one big) to maximize boot space and practicality.
Underbody CNG Tanks: Maruti Suzuki is now introducing underbody CNG tanks in new SUVs, liberating boot space and enabling more usable luggage areas, a major development in 2025
Fully Integrated Kits: All company-fitted models come with kits engineered at the factory, ensuring better durability, safety, and performance than aftermarket CNG fits.

Performance & Durability

Better ECUs: Dual ECUs (for petrol and CNG) offer seamless switching and optimal fueling under all conditions.
Corrosion-Resistant Plumbing: Use of stainless steel pipes and corrosion-resistant ferrules to prevent gas leaks and rust, extending lifespan.
Improved Power & Mileage: 2025 engines can achieve up to 34km/kg thanks to high-pressure injectors, enhanced combustion chambers, and more precise gas metering.

Safety and Convenience

Multiple Airbags: Many new CNG cars offer 4–6 airbags, ABS with EBD, and advanced crash protection (even in CNG variants).
Changeover Switch: Automatic or manual systems that let drivers easily switch between petrol and CNG without performance dips or jerks.
Real-Time Fuel Gauges: Modern CNG cars now have digital fuel displays showing accurate gas levels, a convenience over old pressure-based dials.

Smart Features

Hybrid CNG (Emerging): The first CNG-hybrid tech (petrol + CNG + electric assist) is emerging in select models, combining high efficiency with low emissions.
Connectivity: Infotainment, navigation, and smartphone integration are often available even in CNG variants, addressing past complaints about lower feature content.
BS6/OBD2 Compliance: All factory CNG engines meet India’s strictest emission norms and are ready for new diagnostic and emission-testing regimes.

3. Cost & Market Overview

CNG Car Market Share: As of 2025, company-fitted CNG cars account for 20%+ of new passenger car sales in India, outselling diesel passenger cars for the first time.
Price Range: Pricing spans from about ₹5.8 lakh (Maruti Alto K10 S-CNG) to ₹16 lakh (high-end MPVs, SUVs). Hatchbacks and compact sedans dominate volume but compact SUVs (Tata Nexon, Maruti Brezza, Toyota Hyryder) are now increasingly popular in CNG trims.
