Tata Motors has dropped another teaser for the upcoming Sierra EV, and this one gives away a key detail. The electric SUV will get an all-wheel-drive setup, or QWD in Tata’s terminology, similar to the system seen on the Harrier EV. The reveal comes just days before the Sierra EV makes its debut on June 30. Tata’s teaser confirms that the model will be offered with front and rear electric motors, making it the second dual-motor EV in the company’s line-up.What Tata Sierra EV's teaser showsThe latest video focuses on the AWD version of the Sierra EV.Along with the dual-motor setup, the teaser also shows diamond-cut alloy wheels that appear to be shared with the ICE version. These are likely to be 19-inch units reserved for higher trims. The SUV also gets black cladding, a two-tone rear bumper with a silver insert, and six parking sensors.The Sierra EV stays true to the original model’s upright and boxy stance. It carries connected LED headlamps and tail-lamps, thick B-pillars and the blacked-out rear glass treatment that nods to the 1991 Sierra. Unlike the ICE version, though, the EV gets a sealed body-coloured grille instead of a functional one.— Tataev (@Tataev) Tata Sierra EV Powertrain and BatteryThe Sierra EV is expected to be based on Tata’s acti.ev+ architecture, the same platform that underpins the Harrier EV.It may be offered with two battery options:65kWh75kWhThe all-wheel-drive version is likely to be paired only with the larger battery pack, though Tata has not yet revealed motor outputs or charging times.This means buyers could see both single-motor and dual-motor versions once the SUV goes on sale.Tata Sierra EV Cabin and FeaturesInside, the Sierra EV is expected to carry over much of the layout seen on the ICE model, though with EV-specific updates.Higher variants may get a triple-screen setup made up of:A 10.25-inch digital instrument clusterA 12.3-inch central touchscreenA 12.3-inch passenger displayLower trims could come with a dual-screen setup and a head-up display.Other expected features include a panoramic sunroof, powered and ventilated front seats, a premium audio system and multiple drive modes.
