Is buying the Tata Tiago Petrol AMT or the Tata Tiago CNG + Petrol AMT a good decision, considering that I do not drive much? My monthly running is around 500 km.
Go for the Tiago petrol automatic. With only 500 km a month, the money you save on CNG won’t recover the higher upfront price and the compromises for a long time. The petrol feels smoother and livelier in traffic, the gearbox works better with it, and you keep your full boot for luggage. CNG adds weight, cuts boot space, and performance drops when you switch to gas, which you’ll feel on flyovers and quick overtakes.
If your city has patchy CNG supply or long queues, the convenience gap gets wider. Petrol also needs less planning on highway runs, and service is simpler.
One honest catch: your running cost per km will be higher on petrol. If fuel prices worry you, or your usage could jump to 1,000+ km a month and you plan to keep the car 7-8 years, the Tiago CNG automatic can make financial sense. For your current 500 km pattern though, petrol automatic is the cleaner, easier choice.
