If you’re inclined toward a diesel, you should go for it, as they are becoming a rare breed in the face of tighter regulations. That being said, your usage is low enough that the higher cost of a diesel variant may not pay off in the long run. You have to also consider the additional maintenance diesel cars now require in the BS6.2 era.
We suggest you check out the new Hyundai Venue, which handily offers both, petrol and diesel options. The diesel is not too exciting, but it does deliver on the torque and fuel efficiency fronts, and mated to smooth manual and automatic gearboxes, it should be a breeze in your moving city traffic commute. The 1.0 Turbo Petrol packs more punch and comes with a slick manual, or a quick, if slightly clunky DCT auto. If you’re inclined towards diesel, you can’t go too wrong with the Venue in this segment.
