5 Affordable CNG Cars to Buy This Diwali: Maruti, Tata and Renault Models Compared

October 28, 2026: If you are planning to buy a new car this Diwali, an affordable CNG model could be a good option. CNG cars are popular among buyers because they can offer lower fuel costs than petrol cars, especially for daily commutes. Maruti Suzuki and Tata Motors offer several models in this segment, while the Renault Kwid can also be fitted with a CNG kit through authorised dealers.

The list of affordable CNG cars includes the Maruti Suzuki S-Presso, Alto K10, Renault Kwid, Tata Tiago and Maruti Suzuki Wagon R. Buyers can compare these models based on their ex-showroom prices, claimed mileage, transmission options, boot space and features before making a decision.

1. Maruti Suzuki S-Presso CNG

Ex-showroom price: ₹4.64 lakh to ₹5.14 lakh

If you want to buy a CNG car at a low price, the Maruti Suzuki S-Presso is worth considering. Its LXi (O) and VXi (O) variants come with a factory-fitted CNG kit. The car is powered by a 1.0-litre naturally aspirated petrol engine. In CNG mode, it produces a maximum power of 57 PS and torque of 82 Nm.

According to the company, the S-Presso delivers a claimed mileage of 32.73 km/kg in CNG mode and up to 25.30 km/l in petrol mode. The CNG version is available only with a manual transmission. Boot space may also be limited because of the CNG cylinder.

Its compact size, high seating position and everyday usability make the S-Presso a practical option for city driving.

2. Maruti Suzuki Alto K10 CNG

Ex-showroom price: ₹4.84 lakh to ₹5.34 lakh

The Maruti Suzuki Alto K10 CNG costs around ₹20,000 more than the S-Presso at the entry level. Its LXi (O) and VXi (O) variants come with a factory-fitted CNG kit. Like the S-Presso, it uses a 1.0-litre naturally aspirated engine that produces 57 PS of power and 82.1 Nm of torque in CNG mode.

The Alto K10 CNG has a claimed mileage of 33.40 km/kg, while the petrol version offers a claimed mileage of up to 24.90 km/l. The CNG variant comes with a manual gearbox and does not offer a dual-cylinder setup.

Its affordable price, practical features and safety equipment, including six airbags, make it an option worth considering for budget-conscious buyers.

3. Renault Kwid CNG

Ex-showroom price: ₹5.23 lakh to ₹5.85 lakh

The Renault Kwid offers a different CNG option because its kit is installed through an authorised dealer rather than being factory-fitted. According to the report, the retrofit option is available for the Evolution and Climber variants.

The car is powered by a 1.0-litre, three-cylinder naturally aspirated petrol engine that produces 69 PS of power and 92.5 Nm of torque in petrol mode. Renault has not officially specified the engine's output in CNG mode.

One advantage of the Kwid is that buyers can choose a more feature-rich variant, such as the Climber, with features including a touchscreen and sound system. However, the CNG setup does not offer an automatic transmission or a dual-cylinder configuration. Buyers should also check the kit's warranty and compatibility with their chosen variant before making a purchase.

4. Tata Tiago CNG

Ex-showroom price: ₹5.87 lakh to ₹8.62 lakh

The Tata Tiago CNG is worth considering if you want more flexibility in terms of transmission and boot space. Unlike several other cars on this list, it is available with both a manual gearbox and an AMT automatic transmission, making it an option for buyers who prefer driving convenience in city traffic.

The Tiago uses a 1.2-litre, three-cylinder naturally aspirated petrol engine. In CNG mode, it produces a maximum power of 75.5 PS and torque of 96.5 Nm. It also features a dual-cylinder CNG system designed to retain more usable boot space than a conventional single-cylinder layout.

According to the report, CNG options are available in the Smart, Pure, Pure Plus, Pure Plus A and Creative variants. This allows buyers to choose a model based on their budget and preferred features. However, the Creative Plus variant does not offer a CNG option. Check the latest variant details with a dealer before booking.

5. Maruti Suzuki Wagon R CNG

Ex-showroom price: ₹5.94 lakh to ₹6.49 lakh

The Maruti Suzuki Wagon R CNG is another option for buyers looking for an affordable car with a spacious cabin. Its LXi and VXi variants come with a factory-fitted CNG kit. Like the S-Presso and Alto K10, it uses a 1.0-litre naturally aspirated engine.

In CNG mode, the engine produces 57 PS of power and 82.1 Nm of torque. According to the company, the Wagon R CNG delivers a claimed mileage of 33.47 km/kg. The CNG version is available with a manual transmission.

The Wagon R's main advantage is its relatively spacious cabin, which makes it suitable for families and buyers who regularly travel with passengers. However, buyers looking for more premium features may want to compare its equipment with that of other models in this price range.

Which CNG Car Should You Choose This Diwali?

If your main priority is a low starting price, the Maruti Suzuki S-Presso CNG is worth considering. If you compare the stated mileage figures, the Alto K10 and Wagon R offer higher claimed figures. Meanwhile, the Tata Tiago CNG stands out for its automatic transmission option and dual-cylinder setup. The Renault Kwid may appeal to buyers who prefer its SUV-inspired styling and are comfortable with an authorised dealer-fitted CNG kit.

However, you should not make a decision based only on the ex-showroom price or claimed mileage. Check the final on-road price, local CNG availability, boot space, safety features, servicing costs and warranty conditions before buying. Prices and variant availability may vary by location, so confirm the latest details with an authorised dealer before making your purchase.
