With a 2,500km monthly usage, opting for a diesel car will be a sensible choice. From the Tata stable, you could consider the Altroz or the Nexon. Both of these Tata cars are spacious, well-built, and have excellent safety ratings. Their engine is fuel-efficient, but these aren’t very refined.
The Kia Syros is also a great option you can consider. It is equipped with a smoother, more refined diesel engine, and it has been awarded a 5-star crash safety score by BNCAP. The new Venue shares its platform and powertrain with the Syros, and with a more conventional design, new-age features, and better cabin space than before, it is one option that you must seriously consider.
