The Tata Sierra is set to arrive in Indian showrooms during the first quarter of FY27 (April–June 2026). The SUV, which has been spotted on multiple road tests in recent months, is now in the advanced stages of validation as it moves closer to series production.
Positioned above Curvv EV, below Harrier EV
Within Tata’s expanding electric portfolio, the Sierra EV will slot above the Tata Curvv EV while sitting just below the flagship Tata Harrier EV. This positioning suggests a focus on customers seeking a larger footprint, stronger road presence and a more feature-rich cabin without stretching to the brand’s top-tier electric SUV.
Acti.ev+ architecture at its core
The Sierra EV will be underpinned by Tata’s dedicated Acti.ev+ skateboard platform, engineered specifically for next-generation electric models. This flexible architecture is designed to support varying battery capacities and drivetrain layouts, allowing Tata to tailor the Sierra for multiple use cases and price bands.
Two battery options are expected at launch. The entry variant is likely to feature a pack in the 55kWh range, while higher trims could adopt a larger 65kWh unit shared with the Harrier EV. With the bigger battery, real-world driving range is anticipated to exceed 500 km on a single charge under practical conditions. DC fast-charging capability will be standard, and advanced features such as vehicle-to-load (V2L) and bidirectional charging are also being evaluated.
RWD standard, AWD on the cards
Tata is expected to offer the Sierra EV with both rear-wheel-drive (single-motor) and all-wheel-drive (dual-motor) configurations. If introduced as planned, it will become the second Tata EV after the Harrier EV to offer AWD capability, enhancing traction and performance credentials.
There is also speculation that Tata could deploy its integrated drive unit (IDU) concept, seen in the updated Tata Punch EV, which packages the motor and associated components into a compact module. This setup is aimed at improving packaging efficiency and potentially reducing manufacturing costs, which could translate into competitive pricing.
Designed to echo the original Sierra
Styling will blend nostalgia with modern EV design language. The upright stance and squared-off proportions pay homage to the original Sierra, while contemporary cues such as a sealed-off front fascia, full-width LED daytime running lights, split headlamp clusters and a connected rear light bar define its electric identity. Flush door handles, new alloy wheel designs and pronounced wheel arches are expected to further elevate its visual appeal.
Tech-heavy, three-screen cabin
Inside, the Sierra EV is set to adopt a digital-first layout featuring a triple-screen arrangement—comprising a digital instrument cluster, a large central infotainment touchscreen and a dedicated display for the front passenger. Even lower variants are expected to offer generous equipment levels, while top trims will introduce Level 2 ADAS, a 360-degree camera system, connected car features, powered front seats, ambient lighting and dual-zone climate control.
Competitive play, flexible ownership
To widen its appeal, Tata may extend its Battery-as-a-Service (BaaS) model, currently available with the Punch EV, to the Sierra, allowing buyers to lower the initial purchase price. This move could help the SUV compete aggressively against rivals such as the MG Windsor, Hyundai Creta Electric, Maruti e Vitara and Mahindra BE 6.
