Mitsubishi Fuso Truck and Bus Corp. introduced the diesel-electric Aero Star Eco Hybrid Bus to the Japanese market.
The series hybrid bus cuts emissions of nitrogen oxides and particulate matter by 10% more than required by fiscal 2005 regulations and surpasses the fuel economy target set by the government for fiscal 2015, delivering 5.0 km/liter (11 mpg US or 20 l/100km), according to Mitsubishi Fuso.

The hybrid drive comprises a 4.9-liter diesel engine supplied by Nissan to power a 40 kW generator; a 634V lithium-ion battery pack; and two 79 kW electric traction motors. The bus uses a urea SCR system for NOx reduction.
Ancillary systems such as the air conditioner and the power-steering pump are electric. A new high-efficiency converter was developed for the bus.
Mitsubishi Fuso is targeting sales of 60 units per year, at a price of ¥41.8 million (US$362,000). The conventional version of the bus with a 220 kW engine starts at ¥19.4 million (US$168,000).
