Detroit Diesel's Automotive DELTA Engine Named One of the Top Technologies of 1999

    DETROIT, Jan. 11 -- During the North American International
Auto Show, Detroit Diesel Corporation (DDC) announced that its
DELTA automotive engine was recognized as one of the top technologies of 1999.
    SAE's Automotive Engineering magazine, December 1999, named the new DELTA
engine as one of the top 15 technologies of 1999.  The article, by Kami
Buchholz, reads as follows.

    Detroit Diesel capitalized on its knowledge from other product lines,
    including the high speed direct-injection engine and its one-million-
    miles-plus Series 60 heavy duty engine, as well as input from several key
    suppliers, to develop the new SUV-specific, 4.0L V6 engine.  The 24-valve,
    turbocharged, intercooled direct injection diesel engine, which produces
    157 kW (210 hp) @ 4000 rpm, arrived 228 days after its conception.

    In a typical engineering program, going from CAD data to a machined engine
    block and head entails a 20-40 week timetable.  By using rapid
    prototyping, Detroit Diesel's Engine Light Truck Application (DELTA)
    program took 10 weeks for both engine block and head to be "as cast" and
    machined.  With its new product, Detroit Diesel officials said they can
    fill a light truck / SUV engine void by offering a diesel that makes
    little noise, meets emissions requirements, lasts for 400,000 km (250,000
    mi), and out-gains gasoline engines in fuel economy by as much as 70%.

    Charlie Freese, Director of Automotive Sales for Detroit Diesel, added,
"We are pleased to have been recognized for the success of our DELTA engine
development and technology.  Our work on the DELTA engine is representative of
DDC's design and development capabilities along all product lines.  In fact,
we used the same approach to develop the new 3.0L VECTER automotive engine.
The DELTA was designed for light trucks and SUVs while the VECTER is designed
for high performance automotive applications.  We now have one of the most
complete diesel engine line ups in the automotive industry with 3, 4 & 6
cylinder in-lines and two V6s."
