Tata Sierra Variants Explained: Features, Engine Options, and What the Base ‘Smart’ Model Offers
The legend is officially back. Tata Motors has launched the all-new Tata Sierra with an aggressive introductory starting price of Rs 11.49 Lakh (ex-showroom). Reimagined for the modern era, the Sierra bridges the gap between its iconic 1991 heritage and a futuristic “Living Room on Wheels” concept.
While the top-spec models are loaded with segment-first tech like a triple-screen setup and sliding lounge seats, the real question for value-conscious buyers is: What do you get in the base variant?

- Safety: 6 Airbags, ABS with EBD, and Electronic Stability Program (ESP) are expected to be standard.
- Suspension: Independent lower wishbone front suspension and semi-independent twist beam rear suspension.

Verdict on Base Model: The Smart+ is ideal for those who want the iconic Sierra look and the practicality of a large SUV (622L boot space) but plan to add aftermarket accessories for infotainment and style.
