The CNG vehicles market is growing, driven primarily by the expansion of CNG refueling networks, increased gas availability, and greater integration of dedicated and bi-fuel CNG systems by OEMs. Meanwhile, the adoption of LNG vehicles is being supported by the development of high-capacity LNG fueling infrastructure and fuel systems tailored for heavy-duty applications. This expansion in infrastructure and technology enables OEMs and fleet operators to match gas powertrains with specific duty cycles. CNG is becoming increasingly well suited for high-frequency urban and regional operations, while LNG is better suited to long-haul applications that require higher onboard fuel capacity and longer operating ranges.
Governments Strengthen Emission Targets and Methane Vehicle Support
- Italy’s Ministry of Enterprises and Made in Italy reopened its Ecobonus program with USD 4.7 million allocated for LPG and methane retrofit in M1 passenger cars. The incentive provides about USD 940 for installing a new methane system on eligible Euro 3 or newer passenger cars, supporting the conversion of the existing passenger car fleet to CNG and demand for methane vehicle retrofit systems.
- The EU applies fleet CO2 targets of 93.6 g CO2/km for new passenger cars from 2025 to 2029, tightening to 49.5 g CO2/km from 2030 to 2034, before reaching a 0 g CO2/km target from 2035. These progressively stricter fleet targets are pushing automakers toward lower-emission powertrains and limiting the long-term scope for conventional CNG passenger cars, although CNG can continue to serve selected applications where it helps manufacturers reduce fleet emissions.
- As per the NITI Aayog's 2026 transport analysis, CNG/LNG four-wheelers provide mileage of around 23 km/kg compared with 15 km/L for petrol vehicles, while LCVs provide 19 km/kg mileage for CNG/LNG compared with 14 km/L for petrol and 15 km/L for diesel.
"Passenger cars are expected to capture the largest market share in the CNG vehicles market during the forecast period."
The growth of passenger cars in the CNG vehicles market is supported by OEMs focused on improving CNG system packaging, fuel efficiency, and everyday usability. To achieve this, OEMs are implementing sequential gas injection systems, electronic pressure regulation, and optimized engine control strategies. These advancements improve air-fuel mixing, combustion stability, and the transition between CNG and gasoline operations.
In September 2026, Maruti Suzuki launched automatic S-CNG versions of its popular models: Swift, Dzire, and Baleno. This move expands CNG availability beyond manual transmission applications. Additionally, OEMs are integrating CNG storage systems into vehicle designs through compact cylinder layouts and optimized packaging. This innovation allows OEMs to increase usable fuel capacity while minimizing the impact on cabin and luggage space.
For example, Hyundai offers the EXTER Hy CNG Duo, which includes two CNG cylinders while retaining 225 liters of luggage capacity, thanks to an underbody spare tire. Similarly, Maruti Suzuki offers the Brezza S-CNG with an underbody CNG tank. Advances in CNG powertrain efficiency, transmission options, and cylinder packaging are enabling OEMs to broaden CNG availability across various passenger car models, supporting growth in the passenger cars segment of the CNG vehicles market.
"The CNG segment is expected to hold the largest share of the CNG vehicles market during the forecast period."
The CNG segment is expected to hold the largest share in the CNG vehicles market throughout the forecast period. The CNG segment's growth is supported by the expansion of CNG powertrains in passenger cars and light commercial vehicles, particularly in applications with high annual vehicle utilization.
In the passenger cars segment, government support for domestic CNG component manufacturing is encouraging original equipment manufacturers (OEMs) to adopt more advanced and lightweight CNG systems. For instance, in May 2026, the government supported NTF Energy Solutions in establishing a facility to commercialize indigenous Type IV composite CNG cylinders under India’s Clean Mobility Vision. This development will support lighter CNG storage systems and improved vehicle packaging, enabling CNG integration across a broader range of passenger car platforms, including SUVs and MPVs.
In the light commercial vehicles sector, OEMs are improving CNG vehicle productivity by increasing payload capacity, expanding fuel storage, and designing powertrains for repeated urban and regional operating cycles. For example, Ashok Leyland offers the DOST+ XL Twin Fuel, which features a 1,410 kg payload, a 148-liter CNG capacity, and a claimed range of 500 km, making it suitable for longer operating cycles in logistics and last-mile applications.
The growing availability of factory-fitted CNG passenger cars and improved light commercial vehicle capabilities are driving CNG adoption across personal mobility, urban distribution, last-mile delivery, and regional logistics. Additionally, CNG offers operational efficiency and lower emissions in various applications. Its higher mileage can reduce fuel consumption and operating costs, making CNG a more attractive option for cost-sensitive passenger cars and high-utilization light commercial vehicles.
“Europe is estimated to hold a significant share of the CNG vehicles market during the forecast period.”
An established gas refueling network and an increasing integration of renewable gas into transportation bolster the growth of CNG and LNG vehicles in Europe. By early 2026, Europe had approximately 800 LNG refueling stations, creating a growing infrastructure for LNG truck operations along major freight corridors.
Gasum’s strategy for 2026 to 2030 aims to supply 7 TWh of renewable gas annually by 2027, supported by new investments in biogas production. This includes plans for two Swedish plants, each expected to produce 120 GWh annually, starting in 2028 and 2029. This expansion will enhance the availability of renewable gas for road transport and facilitate the transition from fossil natural gas to biogas.
For passenger cars and LCVs, CNG adoption is becoming more selective as new vehicle registrations increasingly shift toward zero-emission powertrains. However, the existing CNG infrastructure and the availability of renewable biomethane provide a viable path for the continued use of gas-powered vehicles in appropriate applications.
For LNG heavy commercial trucks, the business case is more compelling for long-haul routes, as the technology offers a high range and rapid refueling capabilities. The expansion of Bio-LNG presents a lower-carbon fuel alternative using the same basic vehicle fueling architecture.
Volvo Trucks' 2026 gas-engine portfolio includes a new 13-liter G13 engine with horsepower ratings ranging from 420 to 500 and torque of 2,400 to 2,800 Nm, specifically designed for LNG and Bio-LNG applications in the FM, FH, and FH Aero heavy-duty truck ranges.
The regulatory framework is also supporting infrastructure development in the region. The EU's AFIR (Alternative Fuel Infrastructure Regulation) specifically addresses publicly accessible CNG and liquefied methane refueling points, while the European Commission continues to advocate for biomethane as a renewable gas compatible with existing gas infrastructure. By the end of Q2 2026, Europe’s biomethane production capacity reached 8.2 BCM/year, a 17% increase from 2025 that further enhances the availability of renewable gas for transportation applications. These factors are expected to contribute to growing demand for CNG and LNG vehicles in the region.
Major players in the CNG vehicles market with significant global presence include Maruti Suzuki India Limited (India), Tata Motors Limited (India), Hyundai Motor Company (South Korea), Toyota Motor Corporation (Japan), and Ashok Leyland (India). These players have used organic and inorganic growth strategies, including new product launches, product upgrades, collaborations, partnerships, and agreements, to strengthen their international footprint and capture a greater share of the CNG vehicles market.
