Hyundai EXTER CNG vs Petrol: Which One Should You Buy?

Published: Nov 04, 2026

If you are planning to buy the Hyundai EXTER, choosing between petrol and CNG is an important decision. Both versions offer the same compact SUV design, but they differ in power, transmission options and running costs. The petrol version offers more power and an automatic option, while the CNG version can help reduce fuel expenses if you drive long distances regularly.

Here is a closer look at both options to help you choose the one that suits your daily driving needs.


Hyundai EXTER Petrol and CNG Options Explained

The Hyundai EXTER uses a 1.2-litre Kappa engine in both petrol and bi-fuel versions. The main differences are the fuel used, power output and available transmission options.


1.2-litre Kappa Petrol Engine

The Hyundai EXTER Petrol produces 83 PS of power and 113.8 Nm of torque. It is available with a 5-speed manual or Smart Auto AMT transmission. The AMT is an automated manual gearbox that makes stop-and-go traffic easier to drive.

With more power than the CNG version and two transmission options, the petrol EXTER suits buyers who want flexibility. It is also available across the range, giving buyers more options when selecting a variant.


1.2-litre Bi-Fuel Petrol with CNG

The Hyundai EXTER Hy-CNG can run on both petrol and Compressed Natural Gas (CNG). It produces 69 PS of power and 95.2 Nm of torque when running on CNG.

CNG can cost less per kilometre than petrol, making this version worth considering if you regularly drive long distances. It comes with a 5-speed manual transmission and a factory-fitted dual-cylinder CNG system. The CNG option is available on selected variants, so check the equipment and availability before buying.
