Hi, I am planning to buy a car but am confused between the Tata Tiago CNG and the Swift CNG.
Between the two, the Tiago iCNG makes more sense if the priority is keeping running costs low. It uses twin CNG cylinders mounted under the boot floor, so unlike the Swift CNG, it does not sacrifice as much usable boot space. It also has a slightly more powerful CNG engine and, importantly, is the only one of the two available with an AMT on CNG.
The Swift CNG has the advantage in cabin space and overall refinement. It is 50mm longer in wheelbase and 51mm wider, so there is more room inside, and the 1.2-litre engine is smooth enough for everyday use. However, the Swift CNG is manual only and uses a single CNG cylinder, which takes up more of the boot area.
The Tiago is also the more affordable option, with CNG prices starting significantly below the Swift.
