Tata Sierra CNG arriving this festive season Sierra AWD confirmed for 2027
Tata Motors is gearing up for the launch of the much-awaited Sierra EV on June 30, 2026. The company is also expanding the ICE-powered Tata Sierra by introducing new powertrains. The existing model will receive a factory-fitted CNG kit and the rugged All-Wheel Drive (AWD) variants. Recent real-world spy shots have cleared air on their launch timeline and technical details.
Expected Launch Timeline: Around the Diwali 2026 festive season
Current Status: Spotted during active emissions-rig testing
The Tata Sierra lineup currently available with 3 standard ICE choices: a 1.5L NA petrol, a 1.5L turbocharged petrol and a 1.5L diesel motor. However, the homegrown automaker is diversifying into the premium green segment by introducing a factory-fitted CNG version.
Twin Cylinder Layout: To avoid the cargo compromises that associated with traditional aftermarket CNG kits, the Sierra CNG will deploy Tata’s iCNG Twin-Cylinder Technology. This mounts two separate tanks side by side beneath the trunk floor, leaving the boot completely uncompromised for luggage.
Engine Specs: It is yet to be revealed whether the CNG kit will be offered with the 106bhp, 1.5L NA petrol engine or with the high-performance 160bhp, 1.5L turbo petrol engine for punchier driving experience. We expect the naturally-aspirated engine will suit more with the CNG kit.
Expected Launch Timeline: Mid-2027
Current Status: Officially announced, testing yet to begin
The homegrown automaker has confirmed that the Tata Sierra ICE version will receive a dedicated All-Wheel Drive (AWD) setup in 2027. The new Sierra ICE is built on Tata’s brand new All-Terrain Ready Omni-Energy and Geometry Scalable Architecture (ARGOS) platform, which is engineered to support both FWD and AWD drivetrains along with multiple fuel options.
While the standard versions comes with front-wheel-drive setup, the high-end trims with 1.5L GDi engine are likely to receive the AWD option in 2027.
1.5L Direct-Injection Turbo Petrol - 158bhp and 255Nm. 6-speed manual and a 6-speed torque converter automatic gearbox.
