I want to buy an automatic car. My daily running is around 100 km, with 90% highway use and 10% city driving. I am confused between the Tata Punch CNG AMT and the Kia Sonet Diesel AT. Kindly suggest which one would be the better choice for my usage.

Given you drive 100 km a day and mostly on the highway, the Kia Sonet diesel automatic fits your use case better. The torquier diesel engine means it pulls effortlessly, so overtakes are easy and it cruises calmly for long stretches. The Sonet is also a proper, smooth torque converter automatic compared to the Punch's AMT, so it'll be more seamless to drive with fewer jerks and less effort in slow traffic. On long runs, the diesel’s bigger tank gives a longer range, so you stop less for fuel.

The Tata Punch CNG with automatic suits city-heavy use and those who want the lowest fuel cost, but on the highway, it feels slower, and you need to plan every pass. CNG pumps on many highways are still fewer than diesel, the filling takes longer, and you have to contend with the queues usually seen at CNG pumps. 

Trade-offs with the Sonet: it costs more upfront, and the diesel is a bit louder than a petrol or CNG. Even so, for your high daily highway run, the Sonet diesel automatic lines up best.

I am going to buy a Kia Sonet. Although I am inclined more towards the diesel model, I am really concerned with Suzuki and VW calling off their diesel car sales in India completely. Now with Tesla's entry in Indian Market and the difference between petrol and diesel prices narrowing, Is there a chance that the government, in the near future, will completely ban diesel car sales? Because if they do, the resale value of diesel cars will drop suddenly. [Submitter Vehicle details - Make: Honda, Model:

Yes, some manufacturers like Maruti Suzuki and Volkswagen Group have moved away from diesel passenger cars in India. But that was largely a business decision driven by tightening emissions norms, development costs and their own product strategy, not because diesel is being banned nationally. India is clearly pushing cleaner mobility and stricter efficiency norms, but there is no announced nationwide policy to suddenly ban diesel car sales in the near future.What is true is that diesel may gradually become a smaller part of the passenger car market over time, especially in cities with stricter pollution rules. Delhi NCR already has separate age-based restrictions for older diesel vehicles, but that is a local policy, not a national template.As for resale, yes, diesel resale values could soften over the long term if policy becomes stricter, but it is highly unlikely to be a sudden overnight collapse across India. The bigger question is your usage. If you do high monthly running, regular highway trips and value effortless torque plus efficiency, the Kia Sonet diesel still makes a lot of sense and remains one of the strongest diesel compact SUVs available. If your usage is mostly city commuting with lower annual mileage, then the petrol makes more sense, not because diesel is “dying”, but because your ownership pattern may not justify it.Tesla's entering India does not materially change this equation for a Sonet buyer today. EV adoption will grow, but India’s transition will be gradual, not abrupt.
