New BYD D9RC electric double-deck bus in Singapore

A BYD electric double-deck bus was recently sighted in Singapore, 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. The final model name will only be made known at a later date, after its registration. It is the second electric double-deck bus model in Singapore after the Yutong E12DD.

Trial Bus

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 refer to the model 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 will only be made known at a later date, after its registration.

Bus Specifications

The bus features:

  • BYD Lithium Iron Phosphate battery
  • 2x AC Synchronous wheel hub motors (BYD3425TZA)
  • Luminator ULTIMA Electronic Display System (EDS)
  • Luminator SMART Passenger Information Display System (PIDS)
  • Masats doors
  • TNT Surveillance side alert cameras
  • Ster NewCity seats
  • (TBC) Valeo DD540 air-conditioning
  • Two wheelchair bays, with foldable seat integrated into backrest
  • Licensed passenger capacity of 122 passengers
    (51 upper deck seating + 21 lower deck seating + 50 standing)
  • USB charging ports
Pandemic Public Transport Features

The bus also has 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 push
  • Ventilation windows on lower and upper decks
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.

    Should also consider the K11M for high-demand routes with height restrictions.

    Hopefully this BYDD9RCDD electric bus will be registered in May 2021 as SG4005Z for a trial and lease to SBST and park at SEDEP since the BYDK9SD electric buses park at of.

      I agree… Hope to be for SEDEP.

      SBST have the BYDK9
      SMRT have the Yutong E12DD & SD/BYD C6
      Go-Ahead have the Yutong E12DD & SD
      TTS have Yutong E12DD & SD

      I guess SBST may take in this bus as a demo

        C6 may go over to TT for 825. But since SEDEP has all the BYDs, I’d rather 825 in Seletar. Straight swap with 852.

      As usual, you always hope for SBS. SBST already got B8L and Citaro Hybrid, why not give SMRT or another operator a chance?

      • 26 April 2021 at 11:25 PM

        I dont mind if SMRT get it or maybe for all we know this bus may Debut under Tower Transit for Mandai depot service.

      • 26 April 2021 at 11:52 PM

        As of now, only SEDEP has the chargers for BYD buses, so there is a high chance that the BYD DD bus could go to SBST SEDEP.

    This little window design to make me worry about water leaking during the thunderstorm~~

      Agree. The black finishes around the headlights gives a dark front.
