Good safety and performance

This vehicle offers a spacious, tech-heavy cabin, good segment and iconic look, trusted safety standards, and a robust body shell. Extremely spacious and airy rear seat experience.

Dont Buy - After sales is awwful... you will be stuck

Me and my colleague bought BYD Atto 3 months ago. Its a wondeful car to drive and we were very happy unless the car met with an accident.It require change in back light and some work on truck. No internal damage was done. It has been over 4 weeks, BYD is unable to repair the car.They only have 1 reason, part is not available.I would recommend not to buy as you will be stuck for after sales support and parts.

More Expert Reviews on Sierra EV and Atto 3

Tata Sierra EV First Drive Review

By Sagar Bhanushali12 Jul 2026

The Sierra has been perceived as a good-looking, relaxed family car rather than a sporty SUV, and the instant torque, near-silent nature and effortless performance of an electric powertrain complement that character beautifully.

BYD ATTO3 First Drive Review

By Ninad Ambre12 Dec 2022

The BYD ATTO 3 is a five-seater electric SUV positioned above the E6 MPV. This new electric SUV might be new to the Indian market but is a successful global model. It's based on the brand’s ‘Dragon Face 3.0’ design philosophy which lends the vehicle attractive styling. The tastefully done-up elements comprise a diffused chrome grille with sleek LED headlamps, funky alloys, brushed silver and aluminium accents, and wrap-around LED tail lamps with a light bar. It's a mid-sized SUV with a compact footprint and proportions. Yet, it stands out be it for its nice styling outside or within.
