Tata Sierra EV vs Harrier EV: Price and verdict
Sierra EV is around Rs 3 lakh more affordable than the Harrier EV

AWD price | Rs 25.99 lakh | Rs 29.19 lakh | - Rs 3.20 lakh |
The top-spec Tata Harrier EV’s Empowered trim is around Rs 3 lakh pricier than the Sierra EV’s fully loaded Empowered A trim. Although the Harrier EV is larger, the Sierra EV offers more boot space and a higher claimed range with both RWD and AWD. Unlike the Harrier EV, it gets features like a dedicated screen for the co-driver and more speakers while getting the same driving tech as the Harrier EV. Although it misses out on boss mode, an additional knee airbag and a digital IRVM, a Rs 3 lakh difference makes the Sierra EV a better value-for-money proposition.
