San Diego's Metropolitan Transit System (MTS) has announced the launch of a bus which not only features a
powertrain, but also uses
as fuel. The drivetrain was installed in a regular bus and it's made up from a
ISB Gas Plus engine, a Siemens 165kW electrical generator, two Siemens duo inverters, two Siemens 85kW drive motors and Cobasys-developed NiMH
. Some alterations had to be made to the standard chassis to adapt it to the new configuration. The $
million bus will not only improve overall consumption figures, but will also burn a cleaner fuel which, while still producing CO
, reduces NOx pollutants and noise pollution. All aboard.
