BYD unveiled the world's first 88-foot pure electric bi-articulated bus, its K12A at the company’s headquarters in Shenzhen, China. With a passenger capacity of 250 people, it is the longest pure electric bus in the world and can travel at a maximum speed of 43 mph, according to the company.

Additionally, it is also the world's first electric bus equipped with a distributed 4WD system, which can switch between 2WD and 4WD to meet the demands of different terrains, while also lowering the vehicle’s overall energy consumption.

The BYD K12A is compatible with the global bus rapid transit (BRT) system, featuring an all-aluminum alloy body and BYD’s core technologies of batteries, electric motors, and electronic controls.

The unveiling follows other BYD innovations, including its battery heat management system, energy regenerative system and smart integrated design. The bus is equipped with DC and AC charging ports that can be switched freely to meet customers' every need. One charge can last almost 186 miles, and can therefore respond to the demands of a full day’s operation.
