Scania announces gas-powered double-decker

A gas-powered double-decker will join the UK market in late 2015, Scania has announced.

Speaking at the launch of Reading Buses’ CNG fuelling station, Alan Martin, Manager Special Products – Fleet Sales, says work in conjunction with Alexander Dennis is well underway, with the demonstrator to carry an Enviro400 MMC body.

The gas ‘decker will be powered by the same Euro 6 nine-litre engine already in service in 23 single-deck K270UBs with Stagecoach in Sunderland. Mark Oliver, UK Bus and Coach Fleet Sales General Manager explains that this engine does not require SCR and lacks a variable-geometry turbo, making it less complicated than the diesel unit it has been developed from.

Mr Oliver adds that while there will be a slight penalty in the number of standing passengers which may be carried compared to a diesel double-decker, seating capacity will remain the same. “Operators will be pleasantly surprised by the capacity,” he says, adding that the gas tanks will not be sited within the passenger saloons, although their exact location has not yet been disclosed.

“Our big offering for Euro 6 is gas, in both single- and double-deckers,” says Mr Oliver. “To train an engineer familiar with Scania’s diesel engines to be familiar with gas power units takes just two days.”

Scania will also offer a diesel double-deck chassis at Euro 6, powered by a 250bhp nine-litre engine. This is the same unit which will be used in the Irizar i2 and i3 single-deck buses built on Scania chassis, with Mr Oliver stressing that despite earlier reports suggesting a Cummins unit was to be fitted, Scania’s own nine-litre engine is to be used in both.
