Tata Aeris set to launch on September 25: What to expect

The Aeris will likely stick with the Tigor's current powertrain lineup. That means a 1.2-litre petrol engine and a petrol-CNG option, both offered with either a 5-speed manual or a 5-speed AMT. The electric version, the Aeris EV, could carry over the Tiago EV's battery packs, available in 19.2kWh and 24kWh sizes.
