While the test mule keeps most of its design details hidden, it is evident that Tata Motors is validating the electric SUV across varied road and traffic conditions. The brand has already offered a glimpse of the Sierra EV through official teasers, confirming that while it shares its overall design philosophy with the ICE version, the electric variant will feature several EV-specific visual elements to set it apart.At the front, the Tata Sierra EV is expected to adopt a sealed-off fascia instead of a conventional grille, reinforcing its electric identity. A sleek LED daytime running light bar stretches across the width of the nose just below the bonnet line, giving the SUV a modern and futuristic appearance.
