I previously owned a 110hp, 6-speed diesel Renault Duster, which I have since sold. I am now looking to buy a new diesel SUV and am currently managing with a Maruti Celerio. My daily running is around 60-70km, mostly in and around the city, although I do travel outside the city regularly. I have shortlisted the Tata Sierra 1.5 Diesel Automatic and the 2026 Kia Seltos Diesel Automatic. Which one would you recommend? I have also been told that the Sierra diesel does not require AdBlue. I would appreciate your advice as I need to make a decision soon.

The Kia Seltos Diesel Automatic would be the recommendation here. Coming from a Duster diesel, both the Seltos and Sierra will feel like significant upgrades, but the Seltos is the more rounded package today. The 1.5-litre diesel is refined, proven and very efficient, while the automatic gearbox is smooth and well-suited to your 60-70km daily running. It also offers a premium cabin, good ride comfort and a strong ownership experience.
The Tata Sierra Diesel Automatic is certainly appealing. It offers more road presence, a spacious cabin and should be an excellent long-distance cruiser. One advantage is that its diesel engine does not require AdBlue, as Tata has achieved the latest emission norms using a different emissions control strategy. However, it is important to remember that the Sierra still has a DPF, so it isn't completely free of modern diesel emissions hardware. Fortunately, your usage pattern of 60-70km a day with regular out-of-town driving is well-suited to a modern diesel and should help keep the DPF healthy.
