Swedish bus and truck manufacturer Scania will be showing off their latest hybrid transit bus at the UITP public transport congress in Helsinki next week. Unlike most hybrid buses to date, this one is fueled by ethanol instead of diesel and uses ultra-capacitors instead of batteries. Scania has been working on this bus drivetrain for three years. The Swedes are particularly fond of ethanol as a fuel and Scania is claiming that running this bus on ethanol will reduce ethanol CO2 emissions by up to ninety percent.
The hybrid drive system is claimed to reduce fuel consumption and emissions by twenty five percent or more. Not a lot of detail is given at this point about the hybrid configuration they are using but apparently twelve of these buses will start operating in Stockholm in the next two years.
