In our first drive video of 2024 Tata Tiago iCNG AMT, we tell you all of its big positives and negatives. We mainly drove it in and around Delhi covering some regular traffic areas and hilly sections on the outskirts of Gurgaon. We basically tested the Tiago CNG AMT on three parameters - 1. is it comfortable on hilly/ghat sections or urban flyovers? 2. Is it as involving to drive as the non-CNG version of the car? 3. Is it fuel efficient - what mileage should you expect out of it?
