Does the new Tata Sierra diesel not have a DPF filter? I read a Team BHP review on the Sierra diesel that said the car can be driven without any hassle related to DPF issues. Is this right? Please let me know, as I am confused about whether to pick the diesel or the turbo petrol.

In terms of safety, Tata cars usually have a better track record in crash tests than Kia, but it’s important to remember that star ratings are not the only factor that decides how safe a car is. They tell you how a particular variant performed in a specific set of tests, but things like active safety tech, tyre quality, stability at speed and how the car is driven matter just as much in the real world. The updated Kia Seltos now sits on Kia’s K3 platform, which has been engineered to meet stricter global safety norms and offers better torsional rigidity than the older SP2 architecture, so on paper it is a step up in crash protection, even though we do not yet have an official Bharat NCAP rating to point to for the India-spec car. Kia, like every other manufacturer, still has to comply with India’s mandatory crash regulations, which are aligned with UN regulations for frontal and side impact, so it is not an “unsafe” car just because it hasn’t been independently rated yet.On the Tata side, the new Sierra is built on a modern, heavily reinforced platform and is expected to score very well in Bharat NCAP, with a five-star rating widely anticipated, in line with Tata’s recent record with models like the Nexon and Harrier. That, combined with the inherent advantage of a larger, heavier SUV with a strong structure, will naturally give you more peace of mind if crash safety is high on your priority list. For your kind of usage – mostly open roads and highways over long distances – the Sierra diesel will also feel like the better long-distance car, thanks to its strong mid-range performance, relaxed cruising ability and planted high-speed manners. It is the sort of car that feels unflustered at triple-digit speeds and can munch miles comfortably, which suits your 1.4 lakh km over 10 years kind of running very well.The Seltos, particularly in its latest avatar, is also a competent highway car with a comfortable cabin and good performance, but it doesn’t feel as inherently solid or as planted at speed as a larger, heavier SUV like the Sierra. Where the Kia does score is in its more proven reliability record and aftersales experience, which becomes crucial when you’re planning to keep the car for a decade or more. Tata has improved a lot, but Kia still has the edge in consistency of service quality and hassle-free ownership in most markets. On the question of diesel’s future: stricter emission norms and the shift towards electrification will definitely make diesels less common over time, especially in smaller cars. But for now, for larger SUVs that do a lot of highway mileage, diesel is still very relevant in India, thanks to its superior fuel economy and long-range cruising ability. You’re not looking at a fuel that will suddenly become unusable in the next 8–10 years; what you might see instead are higher costs for emission systems and maybe fewer new diesel launches in the long run. So, if a diesel suits your driving pattern – which in your case, with frequent highway use and a long ownership horizon, it does – it can still be a perfectly sensible choice.

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.
