Dana Corporation Introduces its First Active Electronic Torque-Coupling Differential

    DETROIT, March 8 /PRNewswire/ -- Dana Corporation (NYSE: DCN) today
introduced an electronic torque-coupling differential that offers significant
enhancements in the mobility of all-wheel-drive vehicles.  The differential
was introduced at the 2004 SAE World Congress in Detroit, Mich.

    This new differential is an electronically controlled all-wheel-drive
solution designed to improve vehicle performance.  Specifically, the
electronic differential controls power to the wheels while the torque coupling
transfers torque from front to rear or rear to front, depending on the vehicle
configuration and driving conditions.  This approach offers a single-package
design by integrating the coupling within the differential.
    "Uneven road surfaces can cause the front or rear wheels on a vehicle to
spin," said Chuck Heine, president of technology development for the company.
"On an all-wheel-drive vehicle, Dana's new electronic-differential torque-
management system automatically delivers power to the axle with the most
traction."
    In addition to enhancing vehicle mobility, Dana engineers designed the
coupling to be smaller and as much as 25-percent lighter than other available
products.  Also, because the coupling rotates at the differential case speed,
vibration levels are significantly lower than most current systems, which run
at the faster driveshaft input speed.
    "Dana has a strong heritage of being innovators in this industry," said
Michael J. Burns, Dana CEO and president.  "This new differential is the first
in a family of active AWD products that Dana will be introducing to improve
the ride and handling of all-wheel-drive vehicles, as the demand for this type
of vehicle around the world grows.  The technology behind this product
demonstrates our ongoing commitment to advancing the science of mobility in
the automotive marketplace."
    Dana Corporation is a global leader in the design, engineering, and
manufacture of value-added products and systems for automotive, commercial,
and off-highway vehicles.  Delivering on a century of innovation, the
company's continuing operations employ approximately 45,000 people worldwide
