Mercedes Vehicle Has Xperion CNG Tanks Feeding M 936 G Engine

Daimler is promoting the new version of its Mercedes-Benz Citaro NGT bus, a dedicated-compressed natural gas vehicle with compact, 7.7-liter M 936 G engine and lightweight Type IV fuel cylinders from Xperion.

‘The newly developed gas tanks can be found under a cover on the roof,’ Daimler says of the Xperion CNG cylinders for the new Mercedes-badged Citaro NGT bus. ‘The tanks are made of a composite material with a plastic core and are coated with carbon fiber and glass fiber layers. This combination of materials is both light and highly robust.’

The six-cylinder engine delivers 302 horsepower with peak torque of 1200 newton meters “consistently between 1200 and 1600 rpm,” the company says. It is turbocharged with EGR/exhaust gas recirculation.

“To some extent, the natural gas engine undercuts the Euro VI emissions limits by a considerable margin,” states a release.

‘Three-Figure’ Orders in Hand

The Citaro NGT is available as both a standard “rigid” vehicle and as a longer articulated bus. The Citaro NGT rigid bus can carry up to 96 passengers. The Citaro G NGT articulated bus can carry 153 passengers.

The lightweight CNG cylinders and compact engine help reduce the weight of the Citaro NGT as compared with diesel buses. The rigid version weighs about 485 kilograms more – 1,069 pounds.

“We have already received three-figure orders of vehicles from Madrid and Augsburg,” the manufacturer said.

Daimler is also promoting its new Mercedes-Benz Future Bus with CityPilot, a Citaro-based vehicle described as ‘a milestone on the way to the autonomous city bus, and a revolutionary mobility system for the future.’
