BYD 3-Door Electric SD Bus (LTA 2023 Procurement)

BYD will supply 240 BYD B12 single-deck electric buses to LTA, with buses expected to enter service in December 2024. These buses will be fully-low-floor with three doors.

The bus was showcased in a promotional video published by Zhuhai Guangtong Vehicle Manufacture Co., Ltd., a contract manufacturer of buses based in Zhuhai, China. The bus in the video carries Zhuhai Guangtong badges.

In November 2023, BYD (Singapore) Pte. Ltd. won a tender to supply 240 single-deck electric buses under Contract PT601 for S$108.1 million, representing the largest order of electric buses to date in Singapore. BYD also revealed in a Facebook post that it would supply B12 buses for the LTA tender (final model name TBC, pending local registration).

Other public buses in Singapore built by Guangtong Manufacture are the ADL Enviro500 and the ADL Enviro500 (3-door).

Video screengrabs of the interior reveal seats upholstered in blue and red, with red seats intended as priority seats. Two wheelchair bays are provided, with each wheelchair backrest fitted with a pivoting handlebar and a foldable seat.

Two wheelchair bays are provided, both located opposite the exit door. Each bay accommodates one passenger-in-wheelchair (PIW), and the wheelchair backrest contains both a foldable seat and a pivoting handlebar.

Advanced Driver Assistance Systems and an anti-fatigue system are mounted on the dashboard.

The rear section of the bus is laid out similarly to other BYD B12 buses in Singapore, including the floor step provided for passengers accessing the last row of seats (as seen from the CCTV monitor), despite being positioned at the same height as the facing seats in front.

Model name

The ‘BYD B12’ model designation refers to BYD’s B-series of electric buses built by BYD as integral buses, with a distinctive bodywork design developed by BYD’s design team led by Wolfgang Egger. However, the 240 buses procured by the Land Transport Authority are built by Zhuhai Guangtong on BYD chassis, and could receive a different model designation.

The final model name will be confirmed at a later date, pending local registration.

BYD B12 in Singapore

ComfortDelGro Bus purchased ten BYD B12A03 buses as campus shuttle buses for NUS and NTU, which commenced service in November 2022.

Another BYD B12A03 demonstrator bus (registered SG4013A) was offered to LTA for revenue service trials, commencing service in January 2024.

These BYD B12 units are built entirely by BYD as integral buses, in contrast to the Zhuhai-manufactured buses delivered under Contract PT601.
