Audi R8 Features Delphi's Revolutionary MagneRide Semi-Active Suspension

Audi's mid-engined sports car joins the Audi TT in offering Delphi's MagneRide suspension.

Controlled fluid damping technology continues to gain acceptance in Europe.

Release Date: November 30, 2006

Audi's new R8 road-going sports car, which incorporates the genes of the five-time Le Mans winning race car, will join the Audi TT in featuring Delphi Corporation's revolutionary MagneRide suspension technology.

The R8 will be available for sale in Europe in the first half of 2007.

Called Audi Magnetic Ride this innovative technology uses magneto-rheological fluid-filled dampers to provide continuously variable real-time suspension damping control. The system offers increased damper tuning capability, a very large range of damping, and faster response over valve-based controlled suspension systems. Audi Magnetic Ride delivers both maximum driving dynamics and superior road isolation that results in excellent driver comfort.

Furthermore, drivers can choose from two driving programs with a console-mounted two-position driver preference switch depending on whether they want to drive with maximum road feel and control, or with the emphasis more on ride comfort.

Principle of Delphi's MagneRide technology
Delphi's MagneRide semi-active suspension uses magneto-rheological fluid to provide continuously variable real-time suspension damping control. It responds in real time to road and driving conditions based on input from sensors that monitor vehicle body and wheel motion.

"The legendary success of the racing Audi R8 is well-known," said Daniel Warrell, Delphi Chassis Product Business Unit executive. "We are delighted to apply MagneRide to its road-going namesake."

Audi Magnetic Ride is based on a magneto-rheological principle. When in a magnetic field, small iron particles in the suspension fluid align themselves in the direction of the magnetic flux. The electromagnetic coil is integrated into the damper piston in such a way that when it is energized the magnetic flux runs exactly transversely to the admission ports in the damper piston. As the piston moves, the aligned iron particles cling together and create flow resistance in the flowing suspension fluid.

The greater the energy applied and the stronger the magnetic field, the greater the attractive force between the iron particles, thereby creating greater resistance and damping power. The energy is controlled in relation to driving dynamics and impulses from the road. This means for every road situation optimal damping power is available. This damping power produces - according to OEM desire - a more comfortable feel or sportier vehicle handling.

The control of these dampers is done by an electronic controller that communicates with the vehicle's sensors and other chassis controllers in order to determine the prevailing driving situation in a matter of milliseconds.

Application
Audi uses the magneto-rheological dampers for both comfort and sport. In its basic mode, the suspension allows for a more comfortable vehicle feel. In sport mode, the vehicle offers a more responsive ride thanks to a push of a button.

Because of the greater emphasis on ride comfort in the basic mode, maximum comfort is assured when driving over long distances or uneven surfaces.

The greater emphasis on precise and responsive handling in the sport mode results in even better control at the limit. It also optimally suppresses the transient rolling tendency of the car's body in corners.

Benefits
Because damper valving is eliminated by using magneto-rheological controlled fluid within the damper, the Delphi technology has a very short response time. The damping force is only dependent on the power applied to the magneto-rheological fluid and can be adjusted up to 1,000 times a second. Thanks to the nearly instantaneous and variable control of the power, the damping force can also be set anywhere in the broad range between the full soft and the full firm settings. This means the magneto-rheological dampers respond in real time and with great sensitivity to impulses from the road. The control system loop uses an enhanced Skyhook control strategy to ensure the greatest possible road-to-wheel contact on uneven road surfaces with the least impulse to the car body. This means that the new Audi R8 with Magnetic Ride has superb agility, great driving dynamics and outstanding ride comfort.

For Audi, the low-energy requirements of the system are another benefit. On average, a damper requires just 5 watts of electrical capacity (25 watts at a maximum).

Delphi's magneto-rheological monotube damper requires roughly the same space requirements as conventional dampers or struts. If required, Delphi can supply the complete semi-active system with dampers and struts including the sensors and the control unit.

FORWARD-LOOKING STATEMENT
This press release, as well as other statements made by Delphi may contain forward-looking statements within the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, that reflect, when made, the company's current views with respect to current events and financial performance. Such forward-looking statements are and will be, as the case may be, subject to many risks, uncertainties and factors relating to the company's operations and business environment which may cause the actual results of the company to be materially different from any future results, express or implied, by such forward-looking statements. Factors that could cause actual results to differ materially from these forward-looking statements include, but are not limited to, the following: the ability of the company to continue as a going concern; the ability of the company to operate pursuant to the terms of the debtor-in-possession ("DIP") financing facility; the company's ability to obtain court approval with respect to motions in the chapter 11 proceeding prosecuted by it from time to time; the ability of the company to develop, prosecute, confirm and consummate one or more plans of reorganization with respect to the Chapter 11 cases; risks associated with third parties seeking and obtaining court approval to terminate or shorten the exclusivity period for the company to propose and confirm one or more plans of reorganization, for the appointment of a chapter 11 trustee or to convert the cases to chapter 7 cases; the ability of the company to obtain and maintain normal terms with vendors and service providers; the company's ability to maintain contracts that are critical to its operations; the potential adverse impact of the Chapter 11 cases on the company's liquidity or results of operations; the ability of the company to execute its business plans, including the transformation plan described in this press release, and to do so in a timely fashion; the ability of the company to attract, motivate and/or retain key executives and associates; the ability of the company to avoid or continue to operate during a strike, or partial work stoppage or slow down by any of its unionized employees; and the ability of the company to attract and retain customers. Other risk factors are listed from time to time in the company's United States Securities and Exchange Commission reports, including, but not limited to the Annual Report on Form 10-K for the year ended December 31, 2004, and its most recent quarterly report on Form 10-Q for the quarter ended September 30, 2005, and current reports on Form 8-K. Delphi disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events and/or otherwise.

Similarly, these and other factors, including the terms of any reorganization plan ultimately confirmed, can affect the value of the company's various pre-petition liabilities, common stock and/or other equity securities. Additionally, no assurance can be given as to what values, if any, will be ascribed in the bankruptcy proceedings to each of these constituencies. A plan of reorganization could result in holders of Delphi's common stock receiving no distribution on account of their interest and cancellation of their interests. Under certain conditions specified in the Bankruptcy Code, a plan of reorganization may be confirmed notwithstanding its rejection by an impaired class of creditors or equity holders and notwithstanding the fact that equity holders do not receive or retain property on account of their equity interests under the plan. In light of the foregoing and as stated in its October 8, 2005, press release announcing the filing of its Chapter 11 reorganization cases, the company considers the value of the common stock to be highly speculative and cautions equity holders that the stock may ultimately be determined to have no value. Accordingly, the company urges that appropriate caution be exercised with respect to existing and future investments in Delphi's common stock or other equity interests or any claims relating to pre-petition liabilities.
