Fuji Heavy Industries Ltd. unveiled a new gasoline-electric hybrid engine equipped with a more powerful motor at a technology workshop held Monday by the General Motors Corp. group in Tokyo.

The new hybrid system consists of a horizontally opposed engine, an electric motor that can generate 100 kw and a manganese lithium-ion battery, according to the maker of Subaru vehicles.

A 2,000cc vehicle equipped with this system can accelerate to 80 kph using only the electric motor, company officials said. Hybrid vehicles developed by Toyota Motor Corp. and Honda Motor Co. need to use both an engine and electric motor to reach that speed.
