  • The Tata Tiago EV offers an MIDC-tested range of 250km to 315km, depending on the battery pack. However, the real-world range could differ from the claimed figures. The same applies to its ICE versions as well.
  • The average 50km daily running cost of the Tata Tiago EV is much lesser than the price of one-liter petrol, making it an ideal offering for city use. However, it is worth noting that this running cost is derived from the public charging rates. Using a home charger will reduce this even further.
