The BYD K9RC is a fully electric, low-floor double-deck city bus manufactured by BYD in China. The bus was bodied by Gemilang Coachworks, based in Malaysia.
One such example was sighted in Singapore back in April 2021, featuring the Land Transport Authority (LTA)’s lush green livery and SG Bus Decals.
The bus is built by Gemilang Coachworks on a BYD D9RC chassis (based on delivery documents), equipped with two wheelchair bays and other unique features for a pandemic era. It is the second electric double-deck bus model in Singapore after the Yutong E12DD.

Pandemic Public Transport Features
The Land Transport Authority (LTA) procured 60 electric buses in 2018. With no new electric bus orders since, it is likely that the BYD Double-Deck Electric Bus is offered to the LTA as a trial, similar to that of the MAN Lion’s City SD (3 Door) in 2017, and the Mercedes-Benz Citaro hybrid in 2020.
Based on the VIN number (LC06S44P5J1000001), the chassis was built in 2018 by BYD in Shenzhen, China. It is propelled by two BYD3425TZA motors.
The bus’ traction batteries are located at the rear of the lower deck. Like the Yutong E12DD, the passenger compartment on the lower deck ends just above the rear axle.
More batteries are located in the underfloor next to the exit door, on both sides of the bus. This is similar to the BYD K9 (Gemilang) and results in the raised floor and narrow passenger aisle near the exit door.
Delivery documents on the bus initially referred to the bus as the BYD D9RC, which is likely the name of the chassis and not the actual bus. Similarly, the BYD C6 (Gemilang) buses were built on BYD D6R chassis, and BYD K9 (Gemilang) buses were delivered as BYD D9A chassis. The final model name was later confirmed to be the BYD K9RC.
The bus was fitted with registration plate SG4005Z, pending its registration.
Pandemic Public Transport Features
The bus cabin was fitted with several features installed for public transport in a pandemic era. These include:
- Driver cabin protective shield
- Temperature detectors at the entrance doors
- Touch-less bus stopping bell pushes
- Ventilation windows on lower and upper decks
Some of these non-standard features are expected to be removed prior to its registration and revenue service commencement.
Other BYD 3-axle double-deck buses
BYD has produced 3-axle double-deck buses since as early as 2012, when images of a gold-coloured, right-hand-drive BYD K10 was circulated on Chinese social media, strongly hinting at a potential trial with Kowloon Motor Bus of Hong Kong. The purported trial did not materialize.
In June 2020, the BYD B12D three-axle double-deck bus (full model name: BYD6120BD1EV1) was first mentioned in《道路机动车辆生产企业及产品公告》（第334批）, the 334th issue of a regular publication by China’s Ministry of Industry and Information Technology listing new models of domestic road vehicles. A bus operator in Shenzhen took delivery of 10 units in October 2020, configured as sightseeing buses.
BYD also offers the 45-foot (13.7-metre) BYD C10MS for the North American market, unveiled in January 2020 at the United Motorcoach Association’s annual expo in Nashville, Tennessee.
This article was formerly titled “New BYD D9RC electric double-deck bus in Singapore” and updated to BYD K9RC August 2021 to reflect new information about the bus.
