The Tata Sierra has officially made a comeback in a modern avatar. As of late 2025, the internal combustion engine (ICE) version has been launched, while the EV version is scheduled for a release in the first half of 2026.
Here are the complete details and latest updates on the Tata Sierra:
1. Engine & Performance (ICE Version)
The new Sierra is available with three engine options to cater to different driving needs:
- 1.5L Hyperion TGDi Petrol (Turbo): The powerhouse of the range, producing 160 PS of power and 255–280 Nm of torque. It is paired with a 6-speed automatic (Torque Converter) transmission.
- 1.5L Kryojet Diesel: Producing 118 PS and up to 280 Nm of torque. It comes with 6-speed manual and 6-speed automatic options.
- 1.5L Naturally Aspirated (NA) Petrol: A more budget-friendly option producing 106 PS and 145 Nm of torque, available with a 6-speed manual or a 7-speed DCT.
Note: While currently Front-Wheel Drive (FWD), Tata has confirmed that an All-Wheel Drive (AWD) variant is under development.
2. Tata Sierra EV (Upcoming 2026)
The electric version is built on the Acti.ev architecture (the same used for the Punch.ev and Harrier.ev).
- Battery Options: Expected to offer 55 kWh and 65 kWh packs.
- Range: Anticipated to deliver over 500 km on a single charge.

Design & Heritage: “The Modern Classic”
Tata has focused heavily on “nostalgia meeting future” with the new Sierra.
- The Alpine Windows: Unlike the original 3-door model, the new Sierra is a 5-door SUV. To keep the iconic look, it uses a wrap-around glass effect with a blacked-out B-pillar to mimic the original “Alpine” roof while providing the structural strength needed for modern safety norms.
- Clamshell Tailgate: It features a massive rear tailgate that opens wide, similar to premium luxury SUVs, with a 622-litre boot space (expandable to 1,257 litres).
- Wheels: Lower variants get 17-inch steel wheels, while top trims feature massive 19-inch “Magnum” dual-tone alloy wheels.
2. Off-Road & Practicality
While primarily an urban SUV, the Sierra is built on the ARGOS (All-Terrain Ready) architecture.
- Ground Clearance: It boasts a solid 205 mm of unladen ground clearance.
- Water Wading: It can handle up to 450 mm of water, making it capable of surviving heavy monsoon flooding.
- Terrain Modes: The Adventure+ and higher trims include a dedicated selector for Normal, Wet, and Rough road modes.
- Superglide Suspension: Uses Frequency Selective Damping (FSD) to adjust the stiffness of the ride automatically based on the road surface.
3. Interior: “The TheatrePRO Cabin”
The top-tier variants feature a “Lounge” like experience:
- Triple-Screen Setup: A 10.25-inch digital cluster for the driver, a 12.3-inch central infotainment, and a dedicated screen for the front passenger to watch movies or browse apps.
- Audio: A 12-speaker JBL system with a SonicShaft Soundbar integrated into the dashboard.
- Rear Comfort: Features a “Boss Mode” (to move the front seat forward from the back), rear seat recline, and extendable thigh support for long journeys.
4. Color Palette
Tata has named the colors after iconic Indian travel destinations:
- Andaman Adventure (Yellow/Gold)
- Munnar Mist (Green)
- Bengal Rouge (Red)
- Coorg Clouds (Silver)
- Pristine White
- Pure Grey (Dark Grey)
