Choosing the right CNG SUV in 2026 is not easy. Buyers today want good mileage, strong safety, low running cost, and comfort — all in one car. Two popular options that come up again and again are Tata Nexon CNG and Maruti Brezza CNG.
Both cars look similar from the outside, but when you go deeper, they are quite different in driving feel, safety, mileage, and ownership experience.
In this detailed comparison, we will break everything down in simple words so that you can clearly decide which CNG SUV is best for you in 2026.
Engine & Performance Comparison
Tata Nexon CNG
- 1.2L petrol engine with factory-fitted CNG

Verdict:

Mileage & Running Cost
Mileage is one of the biggest reasons people choose CNG cars.

Real-World City Mileage Experience
In daily city driving, CNG mileage depends a lot on traffic, driving style, and AC usage. In real conditions, Maruti Brezza CNG usually delivers around 22–24 km/kg in city traffic, which is still very impressive for a compact SUV. The engine feels relaxed and does not struggle much during stop-and-go traffic.
On the other hand, Tata Nexon CNG gives around 15–17 km/kg in city use. The mileage is lower, but the car feels more planted and confident, especially on bad roads and speed breakers. If your daily drive includes rough roads or highways along with city use, Nexon’s stability becomes a big advantage.

- Nexon CNG
