Expected to launch in 2027, the Maruti Suzuki Fronx hybrid is expected to deliver stellar fuel efficiency; so wait for it, if you aren’t in a hurry.
However, if you need a replacement sooner than 2027, you could opt for diesel versions of the Hyundai Venue or Kia Sonet. They share their diesel engine, which is smooth, refined and very efficient. Both these are equally user-friendly, and both have adequate space for a child seat, although the Venue has an edge over the Sonet in terms of space. Also, in their top variants, both cars offer ADAS along with other safety features, covering your safety requirements well.
