The Tata Sierra is one of the most iconic names in India’s SUV history. Originally launched in the early 1990s, it became a cult classic because of its unique design and three-door layout. After decades of anticipation, Tata Motors finally brought the Sierra back—this time as a modern five-door SUV with an all-new diesel automatic powertrain. The new Sierra maintains the charm of the classic model while adding premium features, futuristic design elements, and a comfortable driving experience.
In this detailed first drive review, we explore the diesel automatic variant of the Tata Sierra to understand how it performs on Indian roads, how comfortable it feels behind the wheel, and whether it lives up to the legendary badge.
A Modern Interpretation of a Legend
Tata Motors has always excelled at blending heritage with innovation, and the new Sierra proves this once again. The redesigned SUV showcases a clean, sculpted profile with a signature glasshouse that pays homage to the original Sierra. The upright stance, muscular wheel arches, clamshell bonnet, and clean LED lighting elements give the SUV a rugged-yet-premium persona.
The rear quarter glass—a standout highlight of the original Sierra—has been re-interpreted beautifully, making the SUV instantly recognizable from a distance. While the new Sierra is a thoroughly modern vehicle, the subtle nod to the past brings a nostalgic charm that many enthusiasts appreciate.
