Despite the government and manufacturers' shifting their focus towards electric cars, the fact remains that we are still far from achieving complete electrification. On the other hand, carbon emission caused by cars is ever increasing, and even today the most affordable way of owning a vehicle that reduces your carbon footprint is to own a CNG car. While the most common was is to retrofit an existing petrol car with an aftermarket CNG kit, we do get company-fitted CNG models as well and Maruti Suzuki India continues to offer the widest range of CNG cars. We get everything from a small car, a hatchback to even an MPV with an option of CNG, and here's a list of best/top CNG cars in India.
1) Maruti Suzuki Alto 800 CNG
The Maruti Suzuki Alto 800 is the cheapest CNG car from the company
The most popular small car in the A segment, Maruti Suzuki Alto 800 is available in CNG variant. The hatchback lately received a facelift, featuring subtle cosmetic updates, while mechanically it remains unchanged. Along with cosmetic upgrades on the outside as well as inside, the hatchback also boasts of additional features such as new fabric upholstery for door pads and seats, additional storage space, remote keyless entry and map pockets among several others.
