    CERRITOS, Calif., April 20 /PRNewswire Interactive News Release/ -- IMPCO
Technologies, Inc. the world's leading source of advanced
alternative fuel systems technology and components for internal combustion
engines, announced today that orders for the company's natural gas fuel
systems products to India have increased over 800% since 1999.
    The Indian market; one of the fastest growing alternative fuel
marketplaces in the Asia Pacific region today, has a total taxi, bus and truck
market potential for alternative fuels at over $1 billion.  There are over
2 million buses, taxis and trucks that are subject to India's Supreme Court
ruling that mandates these vehicles be converted from gasoline and diesel to
clean burning natural gas fuels.
    Mr. Robert Stemmler, Chairman of the Board and CEO of IMPCO, said, "IMPCO
has seen the Indian market expand at enormous rates over the last year.  With
government mandates for the reduction of diesel taxi, bus and truck emissions
by conversion to natural gas; the sale of our products is increasing each
month."
    "IMPCO has received additional orders from Cummins Engine of India and
others which have increased their requirements by over 40% for the next three
months.  This is a sure signal that the key market drivers for alternative
fuels (environment, reduced costs & energy supply) are firmly in place within
India.  The IMPCO business in India has grown from less than $1 million in
sales in 1999 to over $8 million in annualized 2001 sales thus far," Mr.
Stemmler noted.
    Major India cities such as New Delhi, Calcutta and Bombay are implementing
strong regulations directed at air quality in attempts to clean not only their
air, but their reputations as some of the heaviest polluted cities in the
world.  IMPCO's success in significantly reduced air pollution through the use
of clean burning alternative fuels such as natural gas and propane in Mexico
City has demonstrated our ability to successfully support the Indian
government's efforts to reduce pollution.
