I am currently using the Kia Seltos HTX 1.5L petrol (2023 model). It is almost 3 years old and has run around 35,000km. Now, my running is significantly higher than before. Should I sell my petrol car and go for the 1.5L diesel Seltos automatic? I also want all the features that are available in my current car. Is it worth upgrading from the petrol to the diesel engine?

The new Kia Seltos will feel like a proper step-up over your outgoing car on account of its space, feature set, and tech. And if your monthly running is significantly higher than before, it does make sense to opt for the diesel. Sure, a diesel-automatic will be more expensive to buy than a corresponding petrol-automatic; however, it will be much more fuel-efficient, so you will make up for the price difference if your usage is significant. The diesel engine is quite smooth, and its strong low‑end pull makes overtaking and cruising at full load easier. The 6‑speed automatic is smooth and suits long drives well.
Ensure you regularly drive the diesel Seltos on the highway to maintain engine health, as the DPF tends to clog in frequent slow-moving traffic conditions. But if your usage is primarily in the city, with infrequent highway running, we'd recommend opting for the petrol version instead. Or you could consider a Hyundai Creta Electric instead.
