Tata Sierra (EV + ICE) Set to Make a Grand Return:

The original Tata Sierra, sold in the 1990s and early 2000s, holds a cult status in India for its unique boxy, glass-heavy styling and rugged appeal. Now, Tata aims to resurrect that emotional connection while infusing modern design language and advanced technology. The goal: make the Sierra not just a throwback, but a competitive, future-ready SUV.
