You're right, those are two very different cars. Since your usage is mostly city driving, an EV like the Tata Tiago EV is smooth but limited in space and range. The Mahindra XUV 3XO RevX A Turbo on road price is above your budget, and it has limited boot space.
We recommend the Hyundai i20, which is comfortably within your budget. It offers two great petrol engines (1.2 MPI and 1.0 T-GDI) with two smooth automatic gearboxes (CVT and DCT), good features, comfort, and sufficient space for a family of four.
