Both cars are similarly priced, but the Tata Sierra Adventure Plus variant has a few more features than the Harrier Pure X. The Sierra also has a slight edge over the Harrier when it comes to ride comfort, thanks to its Frequency Selective Dampers (FSD). Also, being the newer car, the Sierra feels more desirable, too.
That said, the Tata Harrier has a larger and more powerful 2.0-litre diesel engine, so performance is a lot more effortless in comparison, especially on the highway.
In summary, if you want the newer, better-equipped car, and you're usage is majorly in the city, the Sierra is the one to go for; but if you drive on the highways more often, go for the Harrier, for its larger diesel engine.

Harrier, if you have budget go for the Harrier undoubtedly. There is no comparison between the two.

I 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.

I am confused between sierra tgdi and thar roxx. My driving is 80pc highway 20 pc city. Main requirements are automatic and ample space in car. It should be fun to drive.

Both these are very compelling SUVs that score high on desirability and road presence, as well as on interior space, but also do things very differently from one another. The Thar Roxx has the larger and more powerful engines which, combined with its aggressively calibrated automatic gearboxes, delivery strong and instantaneous performance. The downside, however, is that fuel economy takes a huge nosedive, which might be an annoyance on your long highway journeys. Moreover, the engines are not very refined and can feel a little too highly strung when you aren't driving quickly. And finally, while it is fun to drive in off-road and perhaps dirt-road conditions, it feels relatively large and cumbersome on tarmac, thanks in part to its ladder-frame construction. The Tata Sierra T-GDi, then, proves to be the better choice for you overall, as its monocoque chassis and sharper steering make it a lot more fun on the road. While not quite as powerful as the Mahindra, its 160hp turbo-petrol has more than enough punch and its 6-speed automatic is smooth too. It's also the more comfortable and fuel-efficient of the two by far, which should help on your highway drives.

With your limited running, a petrol-engined vehicle would be advisable. Since you are looking at a top-end automatic version, the Tata Sierra and Kia Seltos are both good options. The Hyryder is good, but it is the oldest of this trio and you won’t see much benefit from its hybrid system with your limited running.Between the Sierra and the Seltos, it depends on where your priorities lie. Both offer refined and powerful 1.5-litre turbo-petrol engines, but the Sierra uses a six-speed torque converter gearbox, which is smoother in the city, while the Seltos uses a 7-speed DCT that is quicker to shift but can sometimes hesitate in traffic. The Sierra is the pricier of the two but also has the roomier cabin and more features.It is worth noting that Tata’s service experience can be hit or miss, while Kia’s is generally regarded as among the best in the segment. If the roomier cabin, features and the sheer road presence the Sierra offers are important to you, then it is the one to have. But if service experience is a priority, then the Seltos is the safer bet. However, before deciding, do take a test drive of both SUVs.
