A diesel engine will deliver punchier performance and better fuel efficiency, but you will have to live with a constant diesel clatter in the cabin – it won’t be as refined as petrol. More importantly, as you rightly pointed out, modern diesels need to be driven at highway speeds at least once every fortnight to prevent clogging of the diesel particulate filter (DPF).
Given your mostly city-focused usage, the Hyundai Creta or Kia Seltos 1.5 petrol with a CVT (automatic) would be a more suitable option to consider.
