New Delhi. After several spy images, videos, official teasers and public displays, the ICE engined Tata Sierra finally goes on sale in India on 25 November 2025. Its booking started from December 15 and it received 70,000 orders in just 24 hours. Its delivery is scheduled to start from mid-January 2026. Tata Motors is now preparing to launch the electric variant of Sierra in the first half of 2026. The official details of Tata Sierra EV have not been revealed yet, but according to the information received so far, let us know what could be special in the upcoming model.
Acti.ev platform in Sierra EV
Acti.ev platform While the new ARGOS (All-Terrain Ready, Omni-Energy and Geometry Scalable Architecture) platform has been given in the ICE variant, the Tata Sierra EV will be based on the Acti.ev platform. Tata’s Acti.ev architecture is also given in Punch.ev, Curvv.ev and Harrier.ev. The platform supports multiple drivetrain systems and advanced technologies such as Level 2 ADAS, V2L (Vehicle-to-Load), V2V (Vehicle-to-Vehicle) functionality and 5G connectivity.
65kWh and 75kWh battery packs
Powertrain taken from Harrier EV Tata Motors can use 65kWh and 75kWh battery packs of Harrier EV for Sierra EV. The 65kWh variant of the Harrier EV comes with a RWD (rear-wheel drive) system and gives an ARAI range of 538km on a single charge. The 75kWh battery pack variant is available in both RWD and AWD (QWD) configurations, offering a range of 627km and 622km respectively. It is expected that Sierra EV will give a range of more than 500km on a single charge.

Most of its features will be taken from the ICE variant, like triple screen setup, panoramic sunroof, JBL sound system, wireless smartphone connectivity, wireless phone charger, TPMS, ESC, 360 degree camera, multiple airbags and other features.
