BYD ATTO 3｜New Bluetooth unlocking
BYD BYD ATTO 3 has been on sale in Hong Kong for several years and also launched a minor facelift in 2025. The exterior changes include full-car design rims and black rear side window shells, but there are not many other changes. The interior has been replaced with an all-black design, especially the "guitar line" in the door storage area has also changed from red to black. Combined with the front and rear seats with yellow stitching, the overall feel is obviously more advanced than before the facelift.
The size is the same as before, with a body length of 4,455 mm and a wheelbase of 2,720 mm, providing ample space and a trunk capacity of 470 L.
In terms of equipment, Bluetooth key and NFC functions have been newly added. The former can be used on a mobile phone that has a BYD dedicated application installed (relevant car information has been added) to unlock and start the car without a key. The NFC function allows you to unlock the car by placing your phone close to the side mirror. In addition, the front seats have a new ventilation function, while the 5-inch digital instrument panel, 12.8-inch rotatable touch screen on the center console and support for Apple CarPlay continue to be provided.

BYD M6｜6/7 seats optional
BYD M6 is a rare seven-seater MPV in the Hong Kong market with an appearance close to that of a station wagon. The front of the car uses a sealed ghost mask and multiple LED headlights with daytime running lights, coupled with 17-inch wheels and a roof rack. Compared with the boxy MPV, it has a more streamlined appearance.
The M6 is available in 7-seat version (2+3+2) and 6-seat version (2+2+2). The two configurations are exactly the same except for the middle row of seats. The nearly 90-degree opening angle of the middle door and the low floor, combined with the handles and pull rods next to the seats, make it easier for passengers to enter and exit the vehicle. The luggage compartment capacity is 652 L, and the trunk space can be increased by folding the rear seatbacks flat.
In terms of equipment, it is equipped with PM2.5 air purification function and can monitor the air index inside and outside the car in real time. The electrically adjustable front seats have ventilation function, sunroof blinds with Cantonese voice control, a 12.8-inch rotatable central touch screen that supports Apple CarPlay and wireless charging, etc.
