Tata Sierra price in Upper Subansiri

The Kia Seltos works very well for your usage because it is extremely easy to drive in the city, thanks to its smooth IVT automatic. It delivers a very seamless driving experience at low speeds, which makes traffic driving stress-free, and this is exactly where it stands out.

It also feels like the more premium and newer car overall, especially on the inside. The cabin quality, fit and finish give it a more upmarket feel, and importantly, it offers a more spacious rear seat, which adds to overall comfort and practicality.

The Tata Curvv is an interesting option and scores well on design and road presence. But as a package, it is still not as refined or as easy to drive as the Seltos, particularly in city conditions.

If you specifically want a Tata car, you can consider the Tata Sierra. It is larger and more comfortable than the Curvv, but within your budget, you will likely be looking at the 1.5 NA petrol with the DCA automatic. While this engine is refined and well-suited for city use, it is not as powerful, and the DCA gearbox is not as smooth as the Seltos’ IVT.

For your requirements, we would suggest going for the Honda Elevate as your first choice.

The Elevate’s 4-cylinder petrol engine feels much smoother and more refined, so you won’t get those vibrations through the gear lever or cabin anymore. It is also easy to drive in the city, and on the highway, it feels stable with predictable steering, which matches what you like about your current car. Overall, it will feel like a clean, proper upgrade in terms of refinement and ease of ownership.

If you still want to stay with Tata because you like the road grip, steering feel, and safety, consider the lower variants of the Tata Sierra petrol.

The Sierra’s naturally aspirated petrol engine is much smoother than your Tiago, and for city driving, it will feel perfectly fine and easy to use. However, on the highway or during overtakes, it can feel a bit short on power. In terms of performance, it may not feel like a major upgrade over your current car, but it will definitely be far more refined, which is one of your main concerns.

Among the automatic options in your budget, here's a shortlist of models well-suited to Bangalore city driving, as well as a tall driver. 

1) Kia Seltos IVT - Very smooth engine and gearbox, roomy cabin, high-quality interior
2) Tata Sierra 1.5 NA DCT - Smooth gearbox, most spacious interior, great ride comfort. Performance is dull, though
3) Renault Duster 1.3 DCT - Smooth gearbox, punchy engine, great ride comfort. Not as spacious as rivals
4) Kia Syros 1.0 DCT - Spacious interior, feature-packed. Negatives include firm ride comfort, and the gearbox can feel jerky at times 

While a full-on 4x4 system is useful for off-roading, a part-time AWD system, as offered by the Maruti Victoris, is handy in low-traction environments like the loose mud you encounter during your 30 percent rural usage. 

Yes, both the new Renault Duster and Tata Sierra have advanced electronics to deal with low-grip environments. But they can't quite compare to an AWD system that drives all four wheels, in case you get stuck in a tight spot. The Victoris AWD, then, proves to be the best compromise between utility and everyday usage. 

While its engine is not super powerful, it is efficient and reliable, and the Victoris offers good high-speed comfort and stability. It should aid you on the highway, which is where you do most of your driving. 

Given what you're looking for in your SUV, the Tata Sierra makes more sense than the Harrier for you. It will feel like a considerable upgrade from your Ford EcoSport Diesel MT, most notably in size and features. And yes, as you mentioned, its standout design is really one of its biggest selling points. 

The Harrier has a much stronger engine, though build quality isn't too far off, but the premium Tata Motors is asking over the Sierra, spec for spec, doesn't feel worth it when the latter is such a good package. The sunroof, unfortunately, has become an inescapable feature in modern cars, especially in these segments, and it's something that you'll just have to accept and not use if you want the rest of the features as well. 

Tata is known to update its models regularly and add new trim levels, and maybe it will introduce more variants that have the rest of the features minus the sunroof. All things considered, the Sierra represents far better value than the Harrier.

With a daily running of around 50 to 60 km, a diesel automatic makes good sense as your monthly usage will easily justify the better fuel efficiency and relaxed nature of a diesel engine.

Between the two options, the Kia Seltos diesel automatic is the better choice overall. The diesel engine is refined, and the 6-speed torque converter automatic is smooth and well-suited for normal city traffic as well as highway drives.

The Tata Sierra is also a strong Midsize SUV with more cabin space. But its diesel engine is noticeably noisier and less refined than the Hyundai-Kia diesel. It is also over a lakh more expensive in comparable automatic variants.

For your usage and preference for an automatic, the Seltos diesel automatic is the more balanced and sensible option thanks to its refinement, smooth gearbox and lower price.
