BYD launches 27m battery-electric bus, world’s longest; distributed 4WD system

BYD launched the K12A at the company’s headquarters in Shenzhen, the world’s first 27-meter (88.6-foot) pure electric bus. 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 70 km/h.


Additionally, it is also the world’s first electric bus equipped with a distributed 4WD system, which can switch between 2WD and 4WD smoothly 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 bus is equipped with DC and AC charging ports that can be switched freely. One charge can last almost 300kms, and can therefore respond to the demands of a full day’s operation.

To date, BYD has delivered a total of more than 50,000 pure electric buses to its global partners. Its electric buses (longer than 10-m) rank Nº1 worldwide in terms of total sales.

To respond to a surge in orders across the globe, BYD is building a more complete R&D and production presence, and has set up factories for pure electric commercial vehicles in China, the US, Brazil, Hungary, and France. BYD’s new energy vehicles have led the world in sales for the last four years (2015-2018) and are operating in more than 300 cities covering over 50 countries and regions across all 6 continents.



A toy with, may be, 300 kWh (or more?) battery packs?


A hand to BYD for the production of a super large e-bus (train) to lower operation (driver's) cost. ) It is not a toy.

The production/sale of 50,000+large e-buses and batteries make BYD the world leader. Many large cities in China are already or will soon operate large 100% e-bus fleets. The rest of the world will have to follow.
