The Yutong E12 is a fully electric single-deck city bus manufactured by Yutong in China. The Chinese manufacturer sells electric buses of different lengths and sizes for local and international markets.

10 units of the Yutong E12 bus were procured by the Land Transport Authority in 2018 as part of efforts to build a more environmentally friendly public bus fleet. A further 10 more Yutong E12DD double-deck electric buses would be acquired, for a total of 20 Yutong electric buses. In total, 60 electric buses were procured from three separate manufacturers at a total sum of S$50.64 million.

Bus operators in China are primary customers of the Yutong E12, with units operating in multiple Chinese cities.  The bus has been successfully exported overseas, with units entering service in Santiago (Chile), Strasbourg and Marseille (France), Newport (UK), Helsinki (Finland), Roskilde (Denmark), and more.

Individual units have also been trialled in various parts of Australia, New Zealand and the United Kingdom.


The Yutong E12 is marketed as a capable electric city bus featuring a suite of driver assistance features, passenger comfort and safety. The bus design incorporates large-capacity lithium iron phosphate batteries which allow the bus to travel roughly between 230 km and 300 km a single charge, under urban road conditions. However, the actual battery capacity of the Singapore units is to be confirmed.

Different range and power consumption figures have been quoted by different sources around the internet, depending on local route conditions under which the Yutong E12 was trialled.

Yutong ReCtrl Electric Drive

Yutong's Electric Drive Technology (Click to expand)

Yutong’s electric drive technology platform is called ReCtrl (or 睿控). In its most iteration, ReCtrl 4.0 (first released in 2017) combines four electric control technologies and four smart technologies as such:

  1. Electric drivetrain
    — highly efficient electric motor replaces the traditional automatic transmission, offering smoother speed changes and reducing maintenance costs
  2. Regenerative braking
    — motor acts as a generator during braking, recovering kinetic energy into electrical energy which is stored in the batteries
  3. Electric steering
    — electro-hydraulic power steering requiring least steering effort
  4. Electric air-conditioning
    — automatically-adjusted heating/cooling with independent zone control, offering at least 15% energy savings over traditional vehicle air-conditioners
  5. Intelligent vehicle energy management system
    — overall management of energy consumption (such as drivetrain and auxiliary systems), using onboard electronic control units and CAN bus network
  6. Intelligent climate control
    — air-conditioning compressor reacts automatically to deliver optimum cooling capacity
  7. Intelligent telematics
    — key vehicle operating parameters are transmitted over the internet for health and status monitoring
  8. Intelligent charging
    — vehicle charging performance is recorded for monitoring

As illustrated by graphics produced by Yutong, the E12 appears to split its battery packs between the rear section and the roof of the bus, with the roof-mounted batteries typically taller than the air-conditioning unit.

The Yutong E12 buses for Singapore appear to have the roof-mounted batteries split into two separate housing units; in front of and behind the air-conditioner, making for a split-type design.


The Yutong E12 is a fully electric city bus manufactured by the Chinese company Zhengzhou Yutong Bus Co., Ltd (郑州宇通客车股份有限公司), which manufactures road vehicles (primarily buses). The E12 is just one of Yutong’s electric bus products, alongside hybrid and regular diesel buses.

Photos of the Yutong E12 first appeared in Chinese commercial vehicle website 提加商用车网 in September 2019. The bus is seen navigating a test track located within Yutong’s assembly plant in Zhengzhou, China.

In comparison with Yutong E12 buses produced for other markets, the Yutong E12 buses in Singapore appear to have the roof-mounted batteries split into two separate housing units; in front of and behind the air-conditioner, making for a split-type design. More information on the drivetrain can be found in the “Background” section above.

On the 18th of October 2019, this Yutong E12 was seen roaming around the west side of Singapore. The occupants onboard consist of SMRT staff only, leading me to conclude that SMRT would be one of the operators of this bus. Here seen is one of the buses with the registration plate of ‘SG3097P’. While this bus looks oddly weird, do pay attention to the placard at the front of the bus saying ‘Bus 8’ which leads me to conclude that there are at least 8 of these buses that will be seen roaming around Singapore in a few months time. This bus illustrated in the photograph is currently based in Bulim Bus Depot. #SG3097P on #OFFSERVICE ___________________________________ #singapore #singaporebus #singaporebuses #lta #ltasg #green #sg❤️bus #yutong #yutonge12 #smrt #smrtbus #smrtbuses #sbst #sbstbus #sbstbuses #towertransitsingapore #tts #ttsbus #ttsbuses #goaheadsg #gas #gasbus #gasbusea #goaheadsingaporebus #goaheadsingaporebuses

    The EDS is the 24×192 LECIP units, similar to those on the B5LH.

    Doesn’t mean successful in China and Europe will be successful here in tropical climate Singapore…The most they will deploy for split shift or shorter hours operation..

      They are not hybrid buses btw.
