Maruti calls its five-speed AMT "Auto Gear Shift" (AGS) and claims 35 km/kg for the Swift S-CNG AMT.

It is also a strong choice for families and fleet-style daily use because of its boot space and safety credentials. It comes in 2 variants and the top-end is priced at Rs. 9.53 lakh, ex-showroom.

Which One Should You Buy?

If price is your main concern, the Aeris is the cheapest CNG automatic today. The Swift is the better pick for a hatchback with Maruti's service network. Choose the Tiago if you want a small, city-friendly car with paddle shifters. Between the Baleno and Dzire, the choice is a hatchback's cabin space or a sedan's boot and extra mileage.

The Tata Altroz iCNG AMT just misses the list. It starts at Rs. 8.69 lakh, but it has features like a sunroof, and its safety rating is strong.

Before you buy, check two things. First, look at CNG station availability in your city. Second, remember that an AMT is not as smooth as a torque-converter or CVT automatic, but it is cheap and works well in heavy traffic. Compare on-road prices, since RTO and insurance costs vary by state, and buy a policy that covers the CNG kit.
