Orbital-Equipped Scooter Wins Environmental Award

    PERTH, Australia, July 2 Orbital is pleased to announce
that China Hainan Sundiro Motorcycle Co. Ltd (Sundiro) has won a major
environmental award in China for its Orbital-equipped HI-JETER(TM) scooter.
The Golden Award of the Fifth China Environment Protection Industry and the
Seventh International Environment Protection Show was in recognition of the
environmentally friendly nature of the 50cc HI-JETER(TM) scooter, which is
produced by Sundiro and equipped with Orbital's direct fuel injection
technology.  Synerject LLC, a 50:50 joint venture between Siemens Automotive
AG and Orbital, supplies the Engine Management Systems.
    "Recognition by Chinese authorities of the HI-JETER(TM) scooter is
particularly pleasing given the prestigious nature of this award and the
quality of the competition", said Mr. Kim Schlunke, Orbital CEO.
    "Emission standards are now being formalised in China and Sundiro is well
ahead of other manufacturers with a scooter that achieves a 40% improvement in
fuel economy and an 80% reduction in emissions."
    The HI-JETER(TM) scooter also provides a clean transport solution in major
Chinese cities which are starting to prohibit or restrict the use of
traditional two-stroke scooters.  The rapid growth in the use of two-stroke
scooters is a major cause of air pollution in China's cities.
    Sundiro has commenced producing HI-JETER(TM) scooters in an initial launch
phase and is marketing these in four of the more polluted cities in China.
"This award will bring added recognition to the product and assist in
generating increasing
sales in China," Mr. Schlunke said.

    Orbital is a leading international developer of engine technologies using
direct in-cylinder fuel injection and lean-burn systems for enhanced fuel
economy and lower emissions.  The company serves the worldwide automotive,
marine, recreational and motorcycle markets.
    Headquartered in Perth, Western Australia, Orbital stock is traded on the
Australian Stock Exchange (OEC), the New York Stock Exchange (OE) as well as
the Berlin (ORE) and Frankfurt (OREA) Exchanges.
