Both the Hyundai Exter CNG and Hyundai Aura CNG are powered by Hyundai's reliable 1,197 cc Kappa bi-fuel engine, producing 68 bhp and approximately 95 Nm of torque. They also share a 5-speed manual transmission, offer seating for five passengers, deliver an estimated CNG mileage of 24–26 km/kg, and use a 60-litre water-equivalent CNG tank, making both models economical options for daily commuting.
The main difference lies in their design and practicality. The Hyundai Exter CNG is a micro-SUV with a higher driving position and bold SUV-inspired styling. It is priced from approximately 7.45 lakh (ex-showroom) and offers around 391 litres of boot space, making it a great fit for buyers who prefer a compact SUV with better road presence.
The Hyundai Aura CNG, on the other hand, is a compact sedan starting at approximately 9.03 lakh (ex-showroom). It provides a slightly larger 402-litre boot, making it better suited for those who frequently carry luggage or value the traditional comfort and stability of a sedan.
For first-time car buyers in Chennai, the Hyundai Exter CNG stands out as a great choice for those who prefer SUV-inspired styling, higher ground clearance, and a more confident driving position. If carrying more luggage and enjoying the balanced ride of a sedan are your priorities, the Hyundai Aura CNG is a practical choice.

Hyundai CNG mileage is a major reason buyers switch from petrol. Real-world figures reported by owners in city conditions are approx. 24–26 km/kg with AC running, and approx around 28–30 km/kg during highway drives with the air conditioner switched off.
At Chennai's average CNG price of approx. 75–80 per kg, running cost works out to roughly 3–3.3 per km - nearly half the cost of running the same car on petrol, where per-km cost is typically 5.5–6.5.
Fuel cost per km (CNG): approx. 3–3.3
Fuel cost per km (petrol): approx. 5.5–6.5
Monthly savings (1,500 km driven): approx. 3,000–4,500 versus petrol
Annual savings (18,000 km driven): approx. 36,000–54,000

Chennai's CNG refuelling network is expanding steadily, though it's still smaller than metro cities like Delhi. Most stations are clustered along high-traffic commercial corridors and near industrial zones.

Since CNG station density varies by locality, it's wise to check the nearest pump to your daily commute route before buying - Lakshmi Hyundai's sales team can guide you on the closest stations to your home or office.

Yes, for city commuters covering 40–60 km daily, Hyundai CNG cars offer strong fuel savings and lower running costs compared to petrol. The main consideration is ensuring a CNG pump is conveniently located along your regular route, since refuelling frequency is slightly higher than petrol due to smaller effective range per fill.

The Hyundai Exter CNG ex-showroom price starts at approx. 7.45 lakh for the base HX3 CNG trim. On-road price in Chennai, including RTO and insurance, comes to approx. 8.5 lakh, going up to approx. 9.2 lakh for higher trims with added features.

The Hyundai Aura CNG on-road price in Chennai is approx. 10.2–10.8 lakh depending on the variant chosen (S or SX). The ex-showroom starting price is approx. 9.03 lakh, with RTO, insurance, and taxes adding roughly 1.2–1.7 lakh in Tamil Nadu.

There is a mild reduction in power output on CNG mode compared to pure petrol mode, which owners commonly describe as slightly softer throttle response, especially uphill or with a full load. City driving performance, however, remains smooth and adequate for daily use.

Factory-fitted CNG kits, like those in the Exter and Aura, are safer and more reliable than aftermarket kits since they are engineered and warranty-backed by Hyundai. They include pressure-tested cylinders and proper safety shut-offs, unlike unregulated aftermarket installations.

You can buy a Hyundai CNG car through Lakshmi Hyundai, a trusted Hyundai dealership in South India with authorised 3S (Sales, Service, Spares) facilities. This ensures genuine pricing, manufacturer warranty, and proper after-sales support across Tamil Nadu.

Hyundai's CNG lineup - the Exter and Aura - offers Chennai buyers a practical, cost-effective alternative to petrol, with genuine savings on daily running costs and Hyundai-backed reliability. As Chennai's CNG infrastructure keeps growing, now is a smart time for first-time buyers to consider this fuel option.
