Tata Motors is geared up to pull the covers off from the new generation of Sierra on 25 November 2025. The company showcased a pre-production concept of the same at the Bharat Mobility Expo earlier in January this year. The Sierra nameplate is being resurrected after the original went off sale in the late 1990s.
Ahead of its official debut, the Sierra has been spotted testing once again. In the latest set of spy shots, a fully-camouflaged test mule of the Sierra is seen carrying an emission testing kit attached to its exhaust. This prototype has been caught on camera in the streets of Pune. The emission testing kit reveals that this is the combustion-powered version of the upcoming Sierra.

For the uninitiated, Tata Motors will bring out both derivatives of Sierra — combustion as well as fully electric. The former will come out first followed by the latter, a few months down the road. Even though the latest test mule was wrapped completely underneath a thick foliage, a few visual elements of the new-gen Tata Sierra stood out clearly.
