The original Tata Sierra, launched in 1991, was a landmark vehicle for the Indian automotive industry—the first modern, long-wheelbase SUV designed and built in India. After years of anticipation, the Tata Sierra nameplate has been gloriously resurrected for the modern era. Launched in late 2025, the new Sierra is not just a retro revival; it is a technological powerhouse built on the new ARGOS architecture, ready to dominate the fiercely competitive mid-size SUV segment.
The 2025 Sierra is a massive departure from its predecessor in terms of sophistication, featuring premium materials, a highly flexible and powerful choice of engines, and a cabin bristling with segment-first technology. Furthermore, the Sierra is the foundation for a highly anticipated electric variant, the Tata Sierra EV, set to launch in early 2026. This comprehensive review details the entire Sierra package—the performance of the ICE (Internal Combustion Engine) variants, the innovative features, the confirmed pricing, and a look ahead at the future EV model.
Design: Nostalgia Meets Futurism
The 2025 Tata Sierra successfully balances the rugged, upright stance of the original with Tata’s contemporary design language, seen in models like the Harrier and Safari.
A. Exterior Highlights: The Iconic Alpine Window
- Boxy Proportions: The new Sierra retains the upright, boxy silhouette that defined the original, giving it a commanding road presence and maximizing interior space.
- The Alpine Window: The signature large glass area over the rear bench (often called the Alpine window) is retained in spirit. In the modern version, this is achieved through a large, flushed, blacked-out C-pillar and roof treatment, maintaining the airy feel while meeting modern safety standards.
- Lighting Signature: The Sierra boasts a futuristic look with a connected LED light bar upfront and full-width LED taillamps (“Light Saber” style), featuring welcome and goodbye animations. The main Bi-LED headlamps are positioned lower on the fascia for a bolder look.
- Premium Touches: Higher variants feature bold 18-inch and 19-inch dual-tone alloy wheels, and the inclusion of flush door handles adds a premium, clean aesthetic typically found in higher-end luxury vehicles.
B. Interior Space and Ergonomics
Built on the ARGOS architecture (All-Terrain Ready, Omni-Energy, Geometry Scalable), the Sierra offers excellent cabin space.
- Dimensions: With a long wheelbase of 2,730 mm, the Sierra provides generous legroom and a massive 622-Litre boot space (expandable to 1,257 Litres), making it one of the most practical options in the segment.
- Seating: The cabin is designed for 5 adults, with a focus on rear-seat comfort, including reclining rear seatbacks (in higher trims) and Boss Mode functionality.

The Future is Electric: Tata Sierra EV Details
The ultimate vision for the Sierra is its all-electric form, the Tata Sierra EV, which is slated for a follow-up launch.
A. EV Platform and Battery
- Platform: The Sierra EV will utilize the advanced Gen 2 Acti.ev platform, the same modular architecture that underpins other upcoming Tata EVs like the Curvv EV and Harrier EV. This platform is optimized for packaging large battery packs and supports AWD layouts.
- Battery and Range (Expected): Although official figures are pending, industry speculation based on Tata’s EV portfolio suggests:
- Battery Capacity: Likely to be offered with two battery packs, potentially 55 kWh and a larger 65 kWh unit.
- Range (Claimed): Expected range is ≈420 km to 500 km on the larger pack (AWD expected in higher trims).
- Expected Charging: DC fast-charging is a certainty, with expectations for high-speed charging to achieve 20% to 80% in under 40 minutes. Features like Vehicle-to-Load (V2L) are also anticipated.
B. EV Price and Positioning
- Launch Timeline: The Tata Sierra EV is expected to be launched in early 2026 (tentative).
- Price (Expected Ex-showroom): The EV variants are estimated to start around ₹19.0 Lakh and go up to ₹25.0 Lakh for the top-end, larger battery pack variants.
- Competition: It will directly compete with models like the MG ZS EV and the upcoming Mahindra XEV 9S, offering a compelling alternative with its unique design and robust feature list.
Conclusion: A New Benchmark in the Mid-Size Segment
The 2025 Tata Sierra is more than a comeback; it is a statement of intent from Tata Motors. By successfully reviving an iconic nameplate and packing it with segment-leading performance (Hyperion TGDi) and unparalleled technology (Triple Screen, L2 ADAS, JBL Soundbar), the Sierra poses a serious threat to established players like the Hyundai Creta and Kia Seltos.
With a highly competitive starting price, a wide range of engine and transmission options, and the promise of both a rugged AWD model and a high-range EV, the Sierra caters to nearly every type of buyer in the mid-size SUV segment. The legacy of the Sierra has been preserved, but its future is decidedly modern, powerful, and technologically brilliant
