•4wI am looking to buy a car mainly for highway commuting and am confused between the Tata Sierra and the 2026 Kia Seltos diesel automatic. My priorities are safety, long-term ownership and reliability. The Sierra may offer better safety, but it is a new product and I am unsure about the reliability of its diesel engine. The Seltos, on the other hand, seems more proven. Which one would be the better choice?

You have correctly summed up the two cars for your requirements. While both the Tata Sierra and the Kia Seltos are yet to be crash tested at either BNCAP or GNCAP, the Sierra is likely to do very well, whereas the Seltos is a bit unknown.
However, bear in mind that this does not mean that it is unsafe. The Seltos meets with the regulations, and the older car secured a 3-star rating, so it's likely the new model could better this. Besides crash ratings, the Seltos is also well equipped on the active safety front with ABS, ESC, downhill brake control and a full ADAS suite.
Given that you are worried about reliability, the Seltos would thus be a safer bet. We would thus say you can go ahead with the Seltos, or if you can wait a few months and then decide on the Sierra.

•2wA Tata car is always suspect in terms of its ride quality and workmanship — areas where the Seltos excels. Moreover, the Sierra is making a comeback after a long hiatus. So, it’s still a unknown quantity, while Seltos is a tried and trusted name. In fact, you can even opt for the 2024 Seltos if the dealership still allows bookings of the older one. Lastly, and this is subjective, looks matter when it comes to a car. On that front, Seltos beats Sierra hands down.

•2wKia/ Hyundai are low rated cars even in middle East, comments on Tata cars come from whom who never owned TATA, just a underdog mentality. Taxi drivers stretch their dollars and even first generation Indiac/ Indigo were largest car pools. Go with TATA a super hit even Africa where people knows what is durability, servicability, and longitivity is. Don't trust Indians who grow up with fixation that India can't produce good things.

•2wLol....First time I am hearing Tata is suspect in Ride quality that too compared to Seltos. Tata is the benchmark in Ride quality in every segment it is present. The Ride comfort is on a different level altogether.
