Delphi Secures Two New MagneRide(TM) Customers

First European Applications for Advanced Suspension System

PARIS, Sept. 24 -- European drivers soon will be able to experience Delphi Corp.'s revolutionary MagneRide(TM) system for the first time, on a European marque, Delphi officials said today at the 2004 Mondial auto show.

Two premier European vehicle manufacturers have selected the technology for future home market applications. The manufacturers will develop controllable dampers utilizing Delphi's newest generation of MagneRide technology to further enhance vehicle ride and handling characteristics. Delphi's collaboration with these two manufacturers on this technology is a first for Delphi in Europe. The customer names and programs remain confidential and will be announced at a later date.

MagneRide is a high-performance, semi-active suspension control system that responds in real time to road and driving conditions based on input from sensors that monitor body and wheel motions. The system provides fast, smooth, continuously variable damping in a cost effective and reliable package that reduces body motion and increases tire road contact on all types of surfaces.

"We are very excited to be working with two new customers to develop technology that will help differentiate their respective brands in the high performance market," said Guy C. Hachey, vice president, Delphi Corp. and president, Delphi Energy & Chassis. "MagneRide enhances both a vehicle's ride and handling performance at the same time, in effect eliminating the traditional compromises engineers must make with conventional, passive suspensions."

Delphi's technical centers in Paris and Krakow, Poland, will be the European centers of expertise for MagneRide. In addition, core-engineering work with take place in Delphi's Dayton, Ohio, USA, technical center.

"Delphi continues to expand its footprint throughout Europe," said Volker Barth, vice president, Delphi Corporation and president, Delphi Europe, Middle East and Africa. "Our global reach, technical prowess and engineering expertise make Delphi the ideal MagneRide partner."

Consumer benefits:

MagneRide(TM) helps provide improved comfort, performance and safety from one revolutionary system, through:

  -- Greater sense of safety and security due to improved wheel control;
  -- Minimized vehicle motion for a flatter ride and more precise,
     responsive handling;
  -- Reduced "dive" and "squat" during braking and acceleration;
  -- Improved load transfer characteristics, providing better roll control
     and handling during sudden, high-speed maneuvers; and
  -- A quieter ride due to improved road isolation.

  Operation:

The system uses Magneto-Rheological (MR) fluids and valve-less dampers to provide a wide range of damping force control with unparalleled responsiveness and high authority. The MR fluid consists of magnetically soft particles suspended in a synthetic fluid. When current is applied to an electromagnetic coil inside the damper's piston, the resulting magnetic field changes the rheology (or resistance to flow) of the fluid, which produces a mechanically simple but very responsive and controllable damping action without any valves. An onboard controller continually adjusts the damping forces up to once every millisecond based on input from four suspension displacement sensors, a lateral accelerometer and a steering wheel angle sensor.

MagneRide has been available only in North America since its debut on the 2002 Cadillac Seville STS. The technology -- marketed as Magnetic Selective Ride Control on the Corvette and Magnetic Ride Control on the Cadillac Seville, XLR and SRX -- has been enthusiastically received by customers and is frequently cited as a key benefit in automotive reviews.

Delphi's European ride dynamics product portfolio also includes the innovative controlled suspension technology, Active Stabilizer Bar System, which can be found on the Land Rover Discovery.
