•4dI am from Bangalore and planning to buy a new car. My usage will be around 70% on highways, and I am confused between the new Seltos Diesel Manual and the Sierra Diesel Manual. I have already booked the Seltos HTX, but now I am wondering whether I should go for the Sierra Adventure+ instead or continue with the Seltos.

With 70% highway use from Bengaluru and a booking already on the Seltos HTX diesel manual, we would stay with the Seltos HTX rather than switch to the Sierra Adventure+ diesel manual. For long runs, the Kia’s diesel feels strong in higher gears, it is refined, and it stays steady and fairly quiet at cruising speeds. The HTX is also well equipped, and its size is easy to live with in the city.
Pick the Sierra Adventure+ only if you truly need more rear cabin space and value extra features, and if you are okay with a bigger car to park and likely a higher on-road price.
Given your highway-heavy use and the booking in hand, the Seltos HTX diesel manual lines up best right now for strong cruising, easy overtakes and simpler day-to-day use in the city.
