Tata Motors is preparing to expand the Sierra lineup with an all-electric version, expected to be launched in the first half of 2026. The move comes at a time when the brand is seeing strong demand for the revived Sierra nameplate, with the ICE-powered Sierra SUV receiving an overwhelming response soon after its launch.
The Tata Sierra EV will mark another important step in Tata Motors’ broader EV strategy, which already includes models such as the Punch EV and Curvv EV.

Strong Response to ICE Sierra Sets the Stage
Tata Motors launched the ICE-powered Sierra SUV in India on November 25, 2025, with bookings opening on December 15. According to the company, the model received 70,000 confirmed bookings within the first 24 hours, highlighting strong market interest.
Deliveries of the ICE version are scheduled to begin by mid-January 2026. With demand already established, Tata is now shifting focus to the electric derivative, which is expected to attract buyers looking for a premium, long-range electric SUV.
Tata Sierra EV Platform: Acti.ev Architecture
Unlike the ICE Sierra, which is based on Tata’s new ARGOS platform, the Sierra EV will be built on the Acti.ev architecture. This is Tata’s dedicated electric vehicle platform that already underpins models such as the Punch EV, Curvv EV and the upcoming Harrier EV.
The Acti.ev platform is designed to support multiple drivetrain configurations and modern technologies. It is compatible with features such as Level 2 ADAS, Vehicle-to-Load (V2L), Vehicle-to-Vehicle (V2V) charging, and 5G connectivity, all of which are expected to be part of Tata’s future EV roadmap.
Expected Battery Options and Driving Range
While Tata Motors has not officially confirmed battery specifications for the Sierra EV, it is expected to share components with the Harrier EV. This means the Tata Sierra EV could be offered with 65kWh and 75kWh battery packs.
On the Harrier EV, the 65kWh battery is paired with a rear-wheel-drive setup and offers a claimed range of 538km. The larger 75kWh battery is available with both RWD and AWD configurations, delivering a claimed range of 627km (RWD) and 622km (AWD).
Based on these figures, the Tata Sierra EV is expected to offer a real-world range comfortably above 500km, positioning it among the longer-range electric SUVs in its segment.
Design and Expected Features
In terms of styling, the Tata Sierra EV is likely to retain the boxy, upright design of the ICE version, with subtle EV-specific updates. These could include a closed-off front grille, aero-optimised alloy wheels, dedicated EV badging, and revised detailing to improve efficiency.
The electric version is also expected to feature a multi-link rear suspension, which should help improve ride comfort and handling.
Inside, most features from the ICE Sierra are expected to carry over. These may include a triple-screen dashboard layout, panoramic sunroof, JBL audio system, wireless Android Auto and Apple CarPlay, wireless charging, Arcade.ev app suite, TPMS, ESC, 360-degree camera, and multiple airbags.
What This Means for Buyers
For buyers considering a premium electric SUV, the Tata Sierra EV could emerge as a compelling option. With a long driving range, modern EV architecture, and a familiar yet distinctive design, it is expected to bridge the gap between mainstream and premium electric SUVs in Tata’s lineup.
As Tata Motors continues to strengthen its EV portfolio, the Tata Sierra EV is likely to play a key role in attracting customers looking for space, technology, and long-distance usability in an electric package.
