Square Wheel Arch cladding, high set-bone and signature curved-over rear Windows will further enhance its impressive appearance. The SUV will have a split headlamp setup on the front and LED light strip connected to the rear. The previous spy image confirms that Tata Sierra will have a floating three-screen setup, with each screen of about 12.3-inch. One screen will serve as infotainment systems, the other as instrument cluster and the third will be for the front co-passenger. The SUV will have dual-tone dashboard, harmon sound system, herrier eV-sound for-spoke steering wheel which will have Illuminated Tata logo and ambient lights.
Tata Sierra's base variant can miss some premium features such as panoramic sunroof, ventilated front seats and Level 2 ADAS (Advanced Driver Assistance System). Other major features may include wireless phone charger, 360-degree cameras, 6 airbags, electronic stability control and more.
Poetrain taken from Harrier EV?
Tata Sierra will initially be introduced with electric powertrain, which will probably be taken from the Harrier EV. The Harrier EV has a single motor with 65kwh battery and single and dual motors with 75kwh battery pack. The small battery version gives a range of 538km, while the big battery variant gives 627km (75kh RWD) and 622km (75KWH AWD). In 2026, petrol and diesel version ICE-guard Sierra will have a new 1.5L natural aspirated petrol and 2.0L diesel engines early next year. Later, a new, more powerful 1.5L turbocharged petrol engine will be added to the SUV model lineup.
