The vehicle is a Mercedes-Benz Econic NGT 2628 x 2/4 NLA, with three axles and a gross vehicle weight of 26 tonnes, a trailing axle and a six-speed automatic transmission, with EEV certification. The M 906 LAG natural gas engine has a displacement of 6.9 liters and develops 205 kW (279 hp). 

The Econic, introduced in 1998,  has been available with natural gas drive since 2002. Fueled with biogas from renewable resources, the Econic is even carbon-neutral. This is the case in Stockholm, where experience with this technology has been gained over more than six years, and the biogas is produced from waste water and to an extent also from household waste. In Singapore the methane is supplied by GPlus, the natural gas sales division of Sembcorp.

Sembcorp Industries is one of the largest environmental companies on the Asian continent, and not only takes care of waste disposal in numerous cities and densely populated areas, but is also involved in energy and water supply in Singapore, China, Vietnam, Great Britain, the United Arab Emirates and Oman. Sembcorp is also a market leader in marine and offshore technology, according to Chief Operating Officer Goh Swee Ooi during the handover of the Econic.

More than 1,000 of the 12,000 Economic units sold over the last 12 years have natural gas drive.
