Tata Motors is finalising the powertrain strategy for its upcoming Sierra EV, with the entry-level Pure variant set to be equipped with a 65 kWh battery pack. Higher-spec all-wheel-drive (AWD) or QWD variants will borrow the larger 75 kWh battery from the Harrier EV, according to reliable dealer sources.
This tiered battery approach allows Tata to offer the Sierra EV at a more accessible price point while delivering stronger performance and range in the top trims.
The Sierra EV is expected to share its powertrain components with the recently launched Harrier EV. The 65 kWh battery in the base Pure variant will power a rear-wheel-drive setup, making it suitable for buyers prioritising efficiency and value. In contrast, the 75 kWh battery will be paired with the dual-motor QWD (Quad Wheel Drive) system on higher variants, offering superior acceleration, traction, and all-weather capability.
Tata’s Harrier EV already uses these two battery options successfully:
- The 75 kWh pack delivers a claimed range of up to 627 km (MIDC) in the Harrier.
- The Sierra EV, being potentially lighter and more aerodynamic in certain aspects, could achieve competitive or even better real-world range figures.
The revival of the iconic Sierra nameplate in electric form has generated significant excitement. The Sierra EV will be built on Tata’s advanced acti.ev+ platform and is scheduled to make its official debut on June 30, 2026.Key highlights expected:
- Dual-motor AWD option (confirmed via recent teasers showing “QWD Dual Motor” badging)
- Modern EV design updates while retaining the rugged, boxy character of the original Sierra
- Premium interior with triple-screen setup, Level 2 ADAS, 360-degree camera, and connected car technology
- Strong focus on both urban usability and light off-road capability
By offering a 65 kWh base variant, Tata aims to make the Sierra EV more competitive against rivals in the ₹18–25 lakh range. The larger 75 kWh AWD version will target buyers seeking premium performance and longer highway range.
This flexible battery strategy mirrors Tata’s successful approach with other EVs like the Curvv EV and Harrier EV, allowing the company to cater to different customer segments without developing entirely new powertrains.
