Chronology
PredecessorBYD K series

The BYD B series are a line of battery electric buses produced by the Chinese vehicle manufacturer BYD. It is the first bus model powered by BYD's Lithium Iron Phosphate Blade electric-batteries. It is available as a 10-metre single-deck (B10), a 11-metre double-deck bus (BD11), a 12-metre single-deck bus (B12), a 12-metre tri-axle double-deck bus (B12D), a 15-metre tri-axle single-deck (B15) and a 18-metre articulated bus (B18).

History

The BYD B series was launched on 29 July 2020, superseding the highly popular BYD K series. The bodywork was designed by Wolfgang Egger. According to BYD, the new bus models feature LED water lamps, USB charging ports, newer-generation wheel hub motors which are 6% more energy-efficient, as well as a lightweight aluminum frame reducing the body weight by up to 10%.

In May 2023, public-private company Metbus, which operates bus services for Red Metropolitana de Movilidad, the Chilean capital Santiago's public transport authority, imported and tested a single B18 articulated bus as part of a pilot program to test the model, with the goal of eventually renovating its entire articulated bus fleet with battery powered buses, during which it registered an overall energy consumption of 13% compared to their older models. As of November of that year, the firm stated that it had very positive views on the bus' performance and was permitted to run it until March 2024, having already pledged to renovate its entire 160-strong articulated bus fleet once financial conditions improve. In October of that year, 10 B12 double-decker buses entered service on Route 520, a temporary bus service operated by Metbus that was originally meant to run during the events of the 2023 Pan American and Parapan American Games, before Red Movilidad prolonged the service to 24 February due to the positive reception of the double-decker buses by its riders. On 27 March 2024, Metbus started running their B12 double-decker buses on Route 555, which runs from Pajaritos metro station to Santiago's main airport, while the company studied other possible routes to run the buses in.

On 30 September 2025, Metbus imported 10 new double-decker buses and permanently assigned them to Red Movilidad's Route 519, which was extended to run between Peñalolén and Pajaritos metro station, coinciding with Chile's hosting of the 2025 FIFA U-20 World Cup. By December, Metbus had a total fleet of 950 electric buses, 30 of which are B12C01 double-deckers, and 94 are a fleet of brand new B18C01 articulated buses for use on Routes 406 and 506, both being the busiest bus routes in Santiago.
